5DIII same ISO performance as 5DII

[bycostello]

people i know who have the 5d3 say it is a stop better....

Not really the place for it (other than the fact it would result in greatly improved ISO performance), but I think 362 would be lovely. That said, I would much prefer 6x6 or 6x7 medium format, but neither will probably spawn from the Canon stable.

It would be nice to use all my Noritar lenses on digital though, even just to see how they'd perform - would require a customised breech-lock adapter though.....

Why not have a 43mm square sensor, and just accept major vignetting at capture, but you've got the entire image circle. You can then decide how to crop in post. You'd never need to rotate your camera, and so no need for vertical grip. Yes, it would be a bit of a waste of silicon, but so what?

You dismiss the silicon waste too easily. A 43mm square sensor will have an area slightly larger than a P45+ digital back and be considerably more expensive to produce compared to a FF sensor.

in terms of high ISO performance, I can definitely say that 5D3 outperforms 5D2!

Natural Light
Canon EOS 5D MK III + 70-200 F2.8 L II IS
ISO 12,800
1/800
F2.8

there's no way my 5D2 could've taken that shot with less noise

without vignetting is ±30.5mm x 30.5mm.

Why do we care about vignetting at capture? Why not have a 43mm square sensor, and just accept major vignetting at capture, but you've got the entire image circle.

If the viewfinder doesnt become square too it can get really annoying to "fix" ur composition of every photo by cropping. Plus i personally dont wanna crop every photo post.

There is only a .5 to 1 stop improvement over the 5D2.

I love it when people say "ONLY a stop better".

Its TWICE as good. How is that "only"? If my paycheck was one stop improved id be pretty damn happy. If my car's gas mileage was one stop better i'd be jumping for joy. If I had an extra stop down below I'd scare some ladies away.

Anyway, rant over. prestonpalmer, this rant was NOT directed at you, just at people in general who are so ungrateful for what amazing technology we have before us.

LOL. I agree completely. As a wedding photographer I am completely stoked about the improvement. If I can get away with using 6400 iso rather than the 3200 I don't exceed with my 5D2, I couldn't be happier! Especially with the new AF and Dual Card slot. Its a perfect wedding photography camera as far as I am concerned. And with regard to Mega Pixels. PLEASE no more than 22MP. That's PLENTY!

Dude. You are my long lost twin. I do weddings as well, and I never went above 3200 on the 5d2 either. Eventually, more MP will be good, when computer processors double in speed and hardrive price per TB is cut in half too. And maybe when blu-ray is as mainstream as DVD for delivery to clients.

Pushing my 5D3 to 6400 still scares the crap out of me. I just need to post process a few more weddings with it to build my confidence Oh, and LR 4.1 OFFICIAL release will be a big deciding factor as well. And as of this year, I am DONE with DVD's. Now Digital Negatives (if they buy them) are delivered on these:

With custom labeling for the client. Auto slideshow built in as well. I hate DL DVD's with a passion!

As far as more MP. I don't see clients ordering anything much bigger than 20x30. So no real need for more MP unless you plan to do a lot of cropping. I would prefer Canon go to a SQUARE sensor next round with a slight MP increase. see this:

Ditto although the more i shoot with it the more confident i am getting up to 12800.

I also just grabbed a pile of sandisk 16GB usb2 drives for delivery for $9.50 each!
sooooo much easier than dealing with DVDs
