5D Mark III [CR1]
« on: May 20, 2011, 07:51:27 AM »
Spec rumors I haven’t heard much about a 5D Mark III in a while, but I did receive some specs this AM. Might as well post them!

It was stressed that below is one prototype, and two others exist.

Specifications

  • 32mp
  • ISO 100-25600 (L1, H1, H2, H3)
  • DIGIC V
  • 4.2fps
  • 19point AF
  • CF Card
  • Slightly larger LCD (new ratio)
  • New autofocus while filming, performance unknown.
  • All the standard video stuff.
  • RAW video still unknown

This is apparently coming before any 1Ds replacement.

Only because of the high-ISO settings it already sounds like a bunch of crap to me.
Why would Canon create a new sensor that wouldn't go past a native 3200 ISO after having one that does a very nice ISO 6400 (5D Mk2)?

I would bet a few dollars on the 5D Mk3 having 19-point autofocus and native ISO 12800 (with at least H2 for 51200 ISO).

I'm hoping we'll get RAW video and maybe even 2K or 3K, but do realise most dreams won't come true ;)

Specs sound good for me.

I want to know ISO performance and cross type AF points.

And for it to have a bloody release date!

I like all the specs except 32mp. Please no..

And also "New autofocus while filming."

Ok, new autofocus is very wanted. But only while filming?!?  :o

32MP? Where am I gonna put all these images into? I just went to Rome for 6 days and I've taken over 64 GB of images! I guess I will need two new 3TB hard disks along with this 5DIII (one for original and one for backup).

I don't mind if Canon will keep it at around 24-27 MP range. I would like to see the noise performance of the current 5DII at ISO 3200 at, say, 6400 or 12800 of the new 5DIII.

I struggle with this too, here are my thoughts...

If large file size is an issue then maybe a full frame is not the right option. In order to get the same pixel density as the 7D, the file size has to be larger.

Also,
You don't have to always shoot with the full size image.

Unlike others, I'm all in favour of as many mp as possible. Storage is cheap and getting cheaper by the day. No, the only problem I have with this rumour is the very last line. I've been holding my breath long enough for the 1Ds mk4 and it's waaaaaay past it's replacement date. The only good news for me is that if the 5D gets 32MP, the IDs will get more. So the 40MP plus rumour is looking possible.

But if Canon wait much longer, they will have to withdraw it yet again because by that time even 40MP will be old hat. I fully understand the current problems in Japan, but don't understand why Canon had not finalised the specs for the 1Ds4 long before that and got it to market.

When you start having more than one value in the raw file per electron in the sensel, it does not make much sense to increase the amplification further, you can just scale in software. Unity gain (1 raw value = 1 electron) happens quite early, say around ISO 1600 or so. Why some cameras still do "native" amplification past unity gain I don't really know, perhaps there are some read noise advantages or something.

Me too :-). I think 40 - 60 megapixels would be ideal for full-frame 36x24mm sensors. Past that the sensor is too small to support it well, and resolution will be higher than needed for most applications. I'd like to be able to produce pictures that can fill a book spread at glorious 400 ppi, which current full-frame cameras can't because resolution is too low. If you shoot detailed landscapes today you'd want a medium format system, which of course are way too expensive for hobbyists. Anyway 32 megapixels is a step in the right direction from my point of view.

english is not my native language. and as I do not understand too much of technique and physics I'd like to ask you if you could translate your obviously intresting post into a more comprehensible one for a non anglo? Hope you don't mind.

So, intuitively I'd take a guess: Even though the native ISO remains ISO 3200 (once read that there is no so called native high ISO beyond that value) it must be a lot cleaner than all what has been seen before.
Is that correct?
If so, is it likely as ISO's remain the same, that ISO 3200 looks pretty much like ISO 400 on my current 30D? In this case, I wouldn't care too much about not being able to shoot above ISO 25600 as there exist the +1 or + 2 EV possibility. Don't know the term...Is that exposure value compensation?

Thanks and regards
Peter

64gb in a few days?

excuse me?

besides, there is always sRAW if you want.

My first thought was exactly the same :D

I know I'm starting to sound like a broken record, but ...

1) Some software packages, like DxO, can't process sRAW & mRAW, so some photographers would be forced to use the full sized raw even though they don't want or need the full resolution.

2) The APS-C sensors today are pretty close in resolution to the 5DmkII - the 600D, 60D, and 7D are all 18MP. It seems Canon is increasing the resolution on the APS-C sensors as well. I don't think 5DmkII owners would be happy to replace it with a 1100D.
