Unusual happening with 40d today

Hehe!! Great. Whenever something happens on TV that the american networks pickup (the Glasgow airport attack being a good example), it's always something like...

"..and in other news, Scotland has been attacked tonight. Glasgow airport in the US of K 400 miles north of London...."

you know the sort of thing.

An eyepiece extender will probably be more reasonable that a nosejob. Then again, Canon accessories can get pretty pricey

Just wondering if it will help with the 2 things mentioned (better contact and less smudging).

And you know we still have horse and carts down here, plus we like saying "corr, luv a duck" a lot and were pearls on all our clothes.

I must admit i have not had any problems with my other Canons LCD's. So far never got a scratch on them and they seem really easy to clean but i do get a lot of nose marks (daren't use it when i have a cold). Guess im just used to it but i have just ordered the screen protector i mentioned in my last post. Not cheap (£8.99) but i have used these before and they actually improve the LCD slightly, especially out doors.
Would be interested to know what you think if you do get an eyepiece extender.

Regarding the eyepiece extender, I just looked on Amazon and found this review (not my words)...

Is this true???!!! Surely something is wrong here.

I am possibly missing something but this truly is the most foolish design ever. Removing the eyecup every time and slotting on a little piece of rubber seems, while of course do'able, a very clumsy method that needs a rethink on *every* model.

At the moment, I'm just carrying a piece of 'Blutack' around and put that over. Works nicely for me.

BTW, I'm after an eyepiece extender to give better contact with my eye and reduce the amount of smudge on the screen. Would I be right to get the EP-EX15 for this? I.e, does it help?

TDCat.

Yep it is a stupid design, somebody is bound to lose the eyecup sooner or later, I hardly ever use the rubber cap, I just keep my eye close to the VF even when on a tripod, so long as you dont stand well back allowing sunlight to shine on the VF it wont cause a problem.

By the time youve removed the eyepiece & put the rubber thing on, chances are you have lost the shot anyway!

.....Those of you with a mathematics degree will know how outrageous that statement is because an increase less than one is actually a decrease. Yes, this item makes the image you see in the viewfinder half the size.

..... "like looking through binoculars the wrong way round".....

...... examine their conscience whether they should continue to sell it ......

Is this true???!!! Surely something is wrong here.

1. You don't understand -- you are supposed to look into the big glass on the front of the camera and aim the back at the subject to compose the picture -- then flip the rig around to take the shot.
   
2. See previous answer.
   
3. Do marketers have a conscience?

It would seem so:

http://www.the-digital-picture.com …ender-EP-EX15-Review.aspx

i have the eye piece extender on mine. i took all the glass/plastic optics from it out. its just made looking thru it and the camera difficult. having just the extender with no glass makes a big difference. i gotta find my eyecup that i bought off of ebay.

Hmmm. I can't speak for the rest of you, but I came equipped with an eye port cover. It's called a "thumb". Works the same on every SLR I've ever used. I even have a spare with me at all times. They're handy for hitch hiking and other things, too.

This problem has been around since the very first AE/TTL metering system was installed in a 35mm SLR's pentaprism (Konica Autoreflex T, 1967). Whenever relying on the internal light meter to set the exposure for you, it's simply good practice to cover the eye port somehow if your eye isn't pressed up against it. There have been various means of dong this over the years, a device on the strap, a little shutter built into the camera, etc. A thumb actually works pretty darned well.

I personally never lost the eyecup from Elan 7, 10D or 30D (knock on wood), but ended up buying a handful of extras for my EOS3s, they seemed to leap off on their own when I wasn't looking.

I was looking at the EP-EX15 too, thought it might be useful, but found the same complaint. It makes the image area so small it's hard to see.

LCD protectors suck, too. I have one of the eFilm/Delkin that pops up to shade the screen, hoping to make it easier to see in bright daylight situations. The shade portion is removable, leaving a clear screen protector/frame below it. Problem is I'm constantly bumping the shade portion loose. It's currently held in place on my 30D with a couple small pieces of gaffer tape. Real class act, let me tell you! I'd have been better off just putting a clear plastic, low tack/static cling type cover on the LCD screen, but have heard/read many folks reports that the LCD cover is actually pretty durable and cheap to replace if it does get damaged.

I don't have a 40D (yet), but this all leads to an interesting question.... I wonder if the 40D instruction manual goes into covering the eye port when using Live Mode on the LCD? If not, it should.

amfoto1,
No, the 40D manual doesn't say anything about using live view and using the eye piece cover. However it does explain how to use the eye piece cover in the 40D manual on page 97 of 40D manual (page 98 on 5D manual)

Since the mirror is flipped up during live view it blocks the light coming in through the viewfinder. The viewfinder is in effect disabled and you do not need to worry about covering the viewfinder. Another reason why live view is primarily intended for tripod work.

WHOA That's what that is!!!

If the above is true and you need the EVF covered i assume when using live view mode the camera takes this in to account?
I didnt read in the manual that the EVF should be covered when live view is active.
I always thought the EVF only needed to be covered when using long exposure times.

It's an optical, not electronic viewfinder. And as noted, when you're in Live View, the mirror's blocking the light from the pentaprism-mounted metering cells. In Live View, the portions of the main sensor corresponding to the selected metering mode (Eval, CWA, Partial, Spot) are used to meter.

Jon,
Sorry but according to the 40D manual that isn't right. According to page 109 of the 40D manual:

and on page 114

I wish you were right but I found this out the hard way

TDCAT asked:

The reviewer is right. I have a brand new oone sitting on my desk here, as it was only on my camera long enough to get me to read the .5 mag info. With the optic in the EP-EX15 the image is smaller than is easy to use.

I have heard and not tried, that if you remove the optic from the ex15 you will be able to see the viewfinder OK. The extender does help the situations you asked about, but as delivered I found the reduced view unacceptable and put it back in the box it came in.
