New hack w/ MLU and AI Servo for 300D.....

[roanjohn]

Heard some talk about the new firmware hack:

MLU
AI-servo (other than sports mode)
ISO 3200
FEC w/ the "JUMP" button.

Oh where oh where can I find the link for this???

Who needs a 10D when you can have all the features in the Rebel??

.................okay.................except for selectable metering :-(

A Rebel hack that gives you MLU? Pretty slick. I haven't heard about that one.

Now for a hack that will give you a black body.

[roanjohn]

after much research.........

Ro1

will try it 2nite :-)

[msvadi]

So they moved FEC to JUMP - this is nice, I never use the jump button anyway. It says that AI Servo does not work right now, but one can select between AIfocus and ONEshot focus. I hope that solves the focus lock problem. For those who are not familiar, there is a problem on 300D with focus-recompose-shoot technique. When one recomposes, the camera sometimes thinks that the subject is moving and adjusts the focus.

The russian site also says that MLU works differently from 10D. Did anybody try the hack? How does one activates the MLU?

I have to say, I'm tempted ... ;) For me, MLU changes everything. I'm just going to wait a few days to make sure that nobody reports any problems.

[The Photo Tuell]

Works so far. ISO 3200 (H in the display) works, but of course it's pretty noisy.

Jump to change FEC works well. Love having FEC when it's needed.

Need to check out MLU still.

Edit: Well MLU works, I can see the difference in the LCD. It's just a bit sharper with MLU.

Guess I could post the examples in a few minutes.

[dsze]

1. Can anyone tell me where I can get firmware newer/better than the 1.1.1 version from Canon? I didn't see a link anywhere in the above post...at least not one in English. :)

2. Will this allow me to alter the size of the JPG that is saved with the RAW file?

3. If I use another firmware, can I revert back to the old firmware if I want to?

thanks,
daniel

[msvadi]

Thanks for the info, guys! ;) Let us know how it works for you.

[msvadi]

There is a lot of excitement about the new hack on dpreviw.com 300D forum. I think they are celebrating there ;)

[EXA1a]

I know that 2/3 to 3/4 of the forum members are actually serious 10D owners but .............

CHEEERS to the 300D/DRebel owners, Yippppeee!
FEC, MLU, One Shot works! No "intelligent" misfocusing of my portraits anymore! What can we ask more?
(okay, AI Servo and selecting metering mode would be great...)

Thanks to our hero Wasia from Russia!

[The Photo Tuell]

Edit: Took out the picture, test was flawed.

MLU works in my quick test. Guess I should have used the remote release, the non-MLU shot might have been sharper.

ISO 3200 is noisy, but it does allow for faster shutter speeds if really needed.

Wish there was a faster way to use MLU though.

Edit: Weird, did another test, this time using the remote cable release. The Non-MLU shot is slightly sharper...is that normal?

Another test and there was no noticable difference.

What's the best shutter speed to test MLU at?

[Adam Hicks]

Ok I know I'm not the only one here who needs a quick description of what MLU is and how it works. Maybe I'm just the only one without enough pride to ask!

Everything else sounds great though!

[msvadi]

Hi, The Photo Tuell.

Can you tell us how does one activate MLU with this hack? I mean, what buttons do you press to turn it on/off?

Regarding the nln-MLU looking sharper than the one with MLU. I hope it only looks that way. It might mean that mirror slap is not an issue.

anyway, the main reason to install the hack is the one shot mode.

With long telephoto lenses or for macro/micro/telescope shots at shutter speeds between ~1/30 and ~1 sec, the mirror slap vibrations can blur the picture, even when using a very sturdy tripod. Mirror lock-up swings up the mirror after pressing the release button, and after a short break the shutter curtain goes. Therefore, vibrations have died down for the exposure.
I'll use it for moon shots and for microscopic shots with my RC1 IR remote release.

I know that I have seen this question asked but I don't recall having ever seen a clear answer. What happens if you use one of these "hacks" and totally hose your 300D formware or want to go back?

If for someone reason (like I'm a clutz) just totally jack it up what (if anything) do I do to get back to where I can have the original (v1.1.1) and take pictures again?

And please, say it in terms a moron can understand.

If the camera completely dies down, you can't reinstall the original firmware before you send in the camera for service.
If it still works, it's possible to download the original Canon 1.1.1 firmware from Canon's site and reinstall it. On that site are instructions for the installation. You only have to set back all custom functions to default before you reinstall.
However, I predict that you will be happy with the modified firmware and never get back to the original, "incomplete" Canon firmware. Maybe to another advanced modified version...

Menu, Custom Function 12 is MLU.

I think I'll have to read the 10D manual to figure out the AI servo and one shot mode, heh.

[Bruce Hamilton]

Now for a hack that will give you a black body.

Don't recall where I saw it, but somebody on the net had stripped down his rebel and painted it black... Looked really sharp!

There have been many discussions on the 300D's so-called "intelligent" AI focus which ought to know better than you when the object is moving or when you're just recomposing. In practice, it's crap.
For instance, you shoot portraits: you aim at the nearest eye of the person with the central AF point, you half-press the release button, you recompose, and now the camera focusses on the background or something else before you can snap the shot. Not always, but way too often. Now it's gone and I'm telling the camera what to do and not vice versa!

--Jens--

[The Photo Tuell]

It might mean that mirror slap is not an issue.

I think that might be true.

Did a couple more tests, this time with the 70-200 F4L (@200) instead of the 50 F1.8. Used remote release, 1/2 second and 1/40 second exposures. Neither have a noticable difference between the MLU or non-MLU shot.

Guess that's good news.

[The Photo Tuell]

Now it's gone and I'm telling the camera what to do and not vice versa!

Is it gone automatically or is there something I need to do in the menu?

Going to read the 10D manual now, hehe.

Edit: Ah I see on the hack page.

- 'Left' button selects the autofocus mode:
PA-1 - ONEShot
PA-2 - AIservo (dosn't work right now)
PA-3 - AIfocusAF

I only seem to be able to get PA-1 though.

[msvadi]

AI servo is not supposed to work yet. But, does it mean AI focus completely gone after you install the hack?

Now it's gone and I'm telling the camera what to do and not vice versa!

Despite what documentation says, AI Servo works fine in my DRebel. All 3 modes works as intended (or at least as they used to work in my old EOS 5). To change between them just press Left arrow and use the main dial to change the setting. Right arrow also change from PA-0 to PA-2, but it seems to modify nothing.

[msvadi]

I have been reading the dpreviwe 300D forums. Apparently, MLU works even better than on the 10D: with 10D one has to press the shutter twice, the first time to lock up the mirror, and the second time to take the shot. With the 300D it's nicer: press once, mirror goes up, delays and then the shutter opens. No need in remote!

[msvadi]

a coouple of users on dpreview reported about problems with their cameras. apparently, problems started after they installed some version of the hack. does not mean that the hack caused it. i think it's only two users. one of them lost the "set" button, other one lost "up" button and the metering modes got mixed:

Probably the hack has nothing to do with it. I took 100s of pictures with the M version of the hack (the last one until now) during a trip and the camera works ok, and I never saw nothing strange with none of the previous versions either, except for the already solved "blinking eye" or the problem present during language switch.

Answer several questions from this thread:

First is DPReviews news on the Black Rebel. See the article is dated back to 8. April. Was this an april's fool dpreview picked up from canon, or have they started producing black Rebels?
http://www.dpreview.com/news/0404/04040801eos300dblack.asp

To the guy mentioning the guy who painted his black, it was probably this:
http://www.slrclub.com/bbs/view.php?id=canon_d30_forum&page=1&sn1=&sid1=&divp age=14&sn=off&sid=off&ss=on&sc=off&select_arrange= headnum&desc=asc&no=72342

I'm happy you 300D users are getting what you've been screaming for since before this camera even hit the shelves :P But I still prefer the "factory-black" with matching rubber-grip my 10D got :)

And lastly, what's the deal with "one shot" on the rebel? Haven't the rebel been able to shoot in "one shot" mode before? Only continous? It doesn't make sense to me, so that's why I'm asking for someone to enlighten me about what the "one shot" issue is. Cause seriously, how many of us 10D users even use the "one shot" mode? It's not like I don't manage to fire one and one shot in continous :P Tried a D2H once, and on that beast I had some troubles doing it, when it was set for 8fps though :P

[Adam Hicks]

How does that 'factory black' match your L tele lenses?

Just curious :twisted:

[The Photo Tuell]

And lastly, what's the deal with "one shot" on the rebel? Haven't the rebel been able to shoot in "one shot" mode before? Only continous?

It's automatically set to AI Focus in the 'Creative Zone' (Manual, Av, Tv, Program). AI Focus means it 'automatically switches between One Shot AF and AI Servo AF according to the subject status.'

Now we can set it to always stay in One Shot mode or always stay in AI Servo mode. Like EXA1a said above, now we have control instead of it being automatic.

Edit: It works, too! Finally figured out an easy test, heh. In One Shot mode I can focus on something with a half-press of the shutter, hold it down and walk towards/away from it and the focus doesn't change. In AI Servo mode I focus on something the same way, walk towards/away from it and the focus changes.

Nice to have control.

[Digital Prophet]

My understanding is that the Black Rebel is only available in Japan. And like some people (I believe it was at DPReview) pointed out, the rest of the world doesn't necessarily get what Japan gets.

Now I personally don't have a problem with the color of my 300D. But it is all about preference. Would I trade my grey case for a glossy black case .... well yeah. But just to be different. Then when everyone had them I'd go back to grey.

Maybe Canon should release a series of colored, camoflaged and tie-died snap on cases like they have for Nokia telephones. :lol:

[msvadi]

vvizard: "one shot" disables AI focus mode - the only DRebel mode in the creative zones. AI makes "focus-recompose-shoot" technique practiaclly impossible, because it can break focus lock.

[Guillermo Freige]

vvizard:
Firts, there is no Black Digital Rebel, but there is a Black Digital Kiss (the Japanese model). Canon´s Chuck Westfall assured there is no plans for a black rebel.
Second, OneShot refers to the AF mode, not the shutter mode. It means the lens locks AF and never changes it unless you releases the button and focus again. The DRebel uses AI Focus (OneShot at the begining, switching to AI Servo if the camera detected movement). Now you can lock the AF mode to OneShot or AI Servo, as in the 10D.

[The Photo Tuell]

the default button in delete prompt was changed from 'Cancel' to 'OK'. So, be aware.

Ahh, that's only right after taking a picture, not when doing playback. Had me confused at first.[/quote]

[roanjohn]

WOW!!! This firmware is the BOMB!!!

Now I have FEC!!! ANd no more annoying AI servo kicking in when you recompose!!! Thank you!!! Thank you!!!

Don't care much about MLU and haven't really tried it yet.

Can't wait for full-time AI servo in AV mode!!!

And also can't wait for selectable metering!!!

Oh.........and ISO 3200 is there if you're tight for speed!!!

YIPEE!!!

And now I can use a cheaper and lighter 420 EX to make beautiful flash photographs!!!

Actually, you have AI Servo in Av mode. The only problem is you can´t take a shot :)
In a previous post I've said AI Servo worked fine to me. It was true until I´ve tried to take an actual picture :(. Shutter release never happens.

Regarding MLU, it´s very useful to me to reduce camera shake handheld induced by the shutter button. I have MLU enabled by default, and use the camera in Continuous shooting mode (MLU has no effect in this mode). When I need to take a stable picture, just switched to single shooting, and shoot. The mirror opens during the button pressing, and a second later the actual picture is taken. I was able to reduce camera shake a lot.

Guillermo................how do you activate MLU??? I'm so excited I can't figure it out.

Ro1

[Guillermo Freige]

Yes!!. You can use AI Servo (PA-2) in the DRebel with a simple trick.
Just keep the shutter button halfpressed during tracking, but when you want to take the actual picture, just release and fullpress the shutter very quickly, and the shutter releases without problems. In continous mode, the camera even keep shooting and tracking the subject between shots, keeping full AI Servo functionality, until the button is released.

[Guillermo Freige]

roanjohn:
Just set "mirror lockup" CF (CF11 I think) to enable, and use Single Shot mode (not Continuous Shot).

This is all so interesting and exciting!

So, functions like MLU are set using custom function settings like a 10D?

Are there any negative side effects from this hack so far?

I've been putting of using a hacked firmware, but there is so much positive response that I might have to give it a try.

I´ve been using the hacked firmware since the first ones, and never had a problem. Probably this void the warranty, but you can always reload the "standard" 1.1.1 firmware before sending the camera to Canon if needed :). The only bug is: you can´t change menu languages with the hacked FW. You must do that with the standard one.

No..........you misunderstood the point. On AV mode, the old firmware forced the user to use AI Focus (I think), where the camera focus and will refocus if it detects movement (not ideal if you focus and recompose).

With the new firmware you have a choice between Single Shot, AI Servo and AI focus...........The only catch is that AI servo does not fully function (which is not a loss cuz you never really had a full-time AI servo mode to begin with). So................you really only gain Single Shot.......and the versatility to switch back to AI focus if you choose.

Hope this helps................No problem with my camera so far :-)

See my following post. There is a trick to use AI Servo in all Creative modes. The Av mode quoted was only an example. There is the same in all Creative modes.
You have no functionality loss with the hached fiwmware (except for the already mentioned inhability to switch menu languages)

[arumdevil]

thanks guys, I already installed the firmware before I saw your answers :D:D so I figured out that I misunderstood what you said.

great stuff

[AzzKicker]

There are a lot of reasons I'm gonna love this firmware. I'm at work so I havent tried it :(.


BUT, I had that FECset program that allowed me to change FEC only via the computers usb to camera. WIth this I have total control of it on the field. I really needed this 2 weeks ago.

Second, ONE SHOT MODE. WHen I use my 50mm f/2.5 lens and I'm shooting a flower or something that slightly moves that little sucker is AutoFocusing like a MOFO!!! To the point I really cant get a shot because its just focusing in and out too damn fast. THis is really good for me, so I dont have to set it to Manual so much.

ISO 3200 is pretty handy for those indoor dark shots like at a stage etc where FLASH is NOT allowed and you need Telephoto. THE MLU will help in these cases as well.


Frankly, unless you have a 10D or higher canon camera, I dont see why you WOULDNT put this hack in your REBEL lol...

[TomC]

Ok. Let me get in on this. I am considering buying a 10D next month. Besides the build and body color, WITH THIS NEW HACK, what, if any, differences are there between the 10D and rebel now?? Please be specific and honest.

in my opinion, the important things are: one still cannot choose between the metering modes, no CF4 - shutter button /AE lock, no CF15 - 2nd-curtain sync. Plus, check the watchout list:

from http://groups.yahoo.com/group/canondigicamhacking/files/Wasia%20B7%20firmware%20features.pdf


• Camera may lock up if you attempt to change the language, maybe possible to change the language but
must be done on the original Canon 300D 1.1.1 firmware
• Some features may not work correctly if you are using another language - use English as a workaround
• If you upgrade and some of the things don't seem to work properly, set the settings in the Custom
Function back to the original values (see below) and install the original 1.1.1 firmware, then upgrade to
the new firmware
• Change the SET button to something other than FEC before upgrading to this version
• When the MLU is enabled and using the self timer, the timer will countdown and beep for 2 seconds then
pause another 7-10 seconds with no countdown in the LCD or beep.
• Names for modes via left/right button will be updated to something more meaningful
• MLU does not work properly when using a flash – flash will fire when the mirror is lifted – not when the
shutter opens

[TomC]

Hah! No thanks. I think I'll stick to my 10D research. I want to be able to select my metering. I dont want the cam to do it for me.

[arumdevil]

I've installed this hack, and it brings some nice features to the 300D, but I'd still rather have a 10D (will upgrade eventually)

[msvadi]

Hah! No thanks. I think I'll stick to my 10D research. I want to be able to select my metering. I dont want the cam to do it for me.

I just want to make sure that we understand each other. At this point, one cannot choose between evaluative, centerweighted and partial metering modes, even with the hack. metering modes determined by camera deafaults. Still, one can have full control over exposure. Further, partial metering is available with "*" button. If you press "*", the camera locks exposure (aperture in Tv, shutter speed in Av, or both in P) according to partial metering at the center area of 9% of the screen. In M, the camera has nothing to lock, it will simply show you by how much you under/overexpose, again, according to partial metering. One can adjust shutter or aperture after pressing the star button. In the M mode, it's quite easy to measure the light accross the scene. Just remember to press "*" when you move the camera.

10D vs. 300D - if you can afford it, go for 10D. if money is an issue, 300D is a very good alternative. You can spend the difference on lenses. Plus, with 300D you get 18mm wide angle for $100. it's far from the best lens on the market, but, check the prices on wide angle lenses.

[roanjohn]

Hah! No thanks. I think I'll stick to my 10D research. I want to be able to select my metering. I dont want the cam to do it for me.

The beauty of digital is that you are able to see your photo after it is taken. Though selectable metering is convenient, you can always check your exposure and compensate if necessary. I don't think that metering is a big issue with the 300D (IMHO), you are still given some latitude between center weighted and partial metering in creative modes.

As far as 2 sec timer is concerned, the remote will allow that option for you.

The biggest breakthrough this hack has given 300D users is by allowing us to use certain features where there would be no workaround otherwise - MLU, Single shot focus and FEC.

- Digital Prophet -

There is a boot loader that is contained in a protected area of the camera's internal flash program memory. It is always executed on power up. It checks to see if there is a firmware update image on an inserted compact flash card, and if so, it writes that image into the updateable area of the internal program flash. It then checks to see if there appears to be a valid camera firmware module in the updateable area of the flash, and if so, if jumps to it. If it turns out that the updateable area of the internal program flash has been hosed with a bad firmware image, the camera my hang or misbehave at that point.

As long as the camera boot loader is working (and it should, unless something electrical has gone wrong with the camera), you can *always* reload the updateable area of the internal program flash, by inserting a compact flash card with a valid firmware image, and cycling the power on the camera (if it's hung, you might have to pull and re-insert the battery). When the boot loader starts, it will see the new firmware image on the compact flash card, and overwrite the bad copy in the updateable area of the internal program flash, then jump to it.

Voila! Restored camera with Canon original firmware.

I sorta skimmed this thread real quick, and I havent made it over to dpreview...but I've known about several firmware hacks since I got my camera a few months ago (was stuck in a heavy course load at school and didnt get to touch it much till these last two weeks) but here were the links I had saved. Never tried either out...always been a whimp about it.
