Quite simple, to keep the price's of the xxD line artificially higher, it's
nothing new companies do it all the time. It's cheaper to use the same hardware and just disable stuff in software than to make a whole other line of sensors.

You're still missing the point. The XTi was the current Rebel when the 30D was released. The 30D didn't have native ISO 3200, and the 40D didn't have native ISO 3200. Both were software pushed. So two generations of cameras that COULD have had native ISO 3200 without cutting into sales of anything didn't for what reason?

Great link, thanks for sharing. Followed the instructions and got it to work on 3x 4 GB memory cards.

Any update as to whether this ISO3200 is genuine or just a software overexposure situation?

If you read this thread further back - around post 326 - (or the other chdk one the developers) you'll see that this is just an "unlock" of an already available capability in the Xti.

no PUSH involved.

I did try to read the whole thing, but it didn't seem conclusive to me.

I'm happy though, works v well. :)

Still need to find a use for those focus patterns though!

Hello,

I installed the hack on my 400D, which I bought as a 2nd hand several month ago,
and it works very well.

At that time I spent a lot of time to find out the number of shutter activations, with no success.

But now with help of this hack it is quite easy :cool:
Also the ISO setting and spot metering seems to work fine, although not yet tested in detail...

Thanks a lot for this very helpfull information :lol:

BR

Werner

P.S.

My stdout.txt shows the following value:

*** unofficial information ***

ReleaseCount: 5060

Hope that I have at least another 5000 shutter releases... :grin:

I'm above 18,000 last time I checked.

1 Shutter replacement. That was probably only at 15,000.

It's really not too bad. If you have any trouble along the way (like I did), just search through this thread and I'm sure it will be answered. My only problem is that I tried to do it when it was first released, and then retried with the updated instructions. I was using an outdated CardTricks, I doubt you will have that problem. Good luck! It's worth it.

Couldn't sleep tonight.. so I did the hack. :) Instructions were top notch. Follow it step by step and you can't screw it up!

Something new to learn now with the spot metering..

I just gotta remember to Delete All pictures instead of formatting my card everytime I want it cleared.

With regards to the Release Count - I don't know how accurate the release count is though. STDOUT.TXT says RC is 12723 for my second hand XTi, even though I know I took at least 6000 shots since I got it and the previous owner said he took 8000 pics or so (filename starts with 8134 when I acquired it). Anyone know if sequence # changes when u change from JPG to RAW? Not a big deal but kind of strange.

Thanks for making this hack!

This hack works in Windows 7 Ultimate. Only issues I encountered was I reformatted my 4GB Sandisk Extreme III to FAT, bootable button in Cardtricks143 was grayed out if your filesystem is FAT32.

:)

Thanks!

Praise and endorsement for the hack's increase of an XTi's highest ISO to 3200, a big increase in usability when combined with Imagenomic's Noiseware.

At first glance, the hack instructions appeared to be too complex to be useful. That was wrong.

Using ISO 3200 for indoor sports has made faster shutter speeds possible, and that's improved the images of the sporting events. Applying the batch conversion from Noiseware has taken care of the higher noise that results from the ISO 3200 setting. Examples in this thread.

The hack and Noiseware combination has made lenses such as the 70-300mm IS USM far more useful. At US $30 for Noiseware, it's a far more affordable and practical combination than faster lenses.

is there a Hack like this for the XT? The low ISO is one of the reasons I upgraded to a 50D
