5D Mark III Specs [CR1]

[Canon Rumors]

The first spec list I am not going to post every spec list I see from anonymous sources. However, it’s slow going at the moment. There’s also a couple of interesting concepts in this list.

It could be a wishlist, it could be legit. Discuss!

Specifications (Japanese to English Google Translated)

• 28megapixel CMOS sensor. Achieved by introducing new technologies such as low-noise photodiode

I'm assuming the "2800 full megapixels" is a mis-translation, or else we can stop right here and throw this one out the window

I updated that. I like to give exact quotes, but I'll just assume 28mp was intended.

I don't see 6 fps and more AF points that the 7D in a 5DIII.  Other than that, there's no news here.  Of course it will have more megapixels and a wider ISO range, because that's the norm.  Of course it will have 1080p.  Of course it will have the 63 zone iFCL metering.  Ok, the electronic level is new to the line, but it's in the 7D and 60D so again, it's obvious.  Video cropping is about the only thing of note.  Woot.

it's I send this link =)

in jap. internet there is rare to see info about 5d mk III, but almost everywhere there is a date of launch about summer-fall 2011

[kubelik]

the approximately 28 MP makes sense, roughly making it the same pixel-sensor density as the 1D Mark IV.  I also highly doubt it's coming with a fancier AF system than the 7D ... 6 FPS would be nice but also a stretch, it'd be more likely to haul the same 5 FPS that the 60D does.

the question is, as the 5D Mark II is really the go-to camera for video shooters, is Canon going to bring the articulated screen to the 5DIII?  honestly, even though I play with video, I couldn't care less for an articulated screen, but it seems like its not beyond reason.

I am also assuming that there will be 720p 60/50 available, not just the 1080p modes ... it'd be awesome to see some really slow-mo stuff ... how about a 72p 72 frame rate mode?  that would be something pretty special that would make the 5DIII stand out against the competition

[blufox]

I didn't understand the autofocus points spec.Can someone please explain it to me?

0.71 magnification , Canon please increase it to somewhere close to .9x.

2 thing worth noting are - No DIGIC V. Dual Digic 4 processors but still 6 fps. What  is it that requires another DIGIC processor now?

Time to put on hold that elusive 7D upgrade.

Whatever it is, it is too late to switch to Noink lol.

The most interesting thing is probably the "low-noise photo diode" thing... Canon seriously need new sensor technologies to keep up with competition.

The 7D still holds up well against new crop cameras, but you need to apply NR and resize etc... Canon needs to be ahead of everyone again without all the processing the users have to go through. And don't get me wrong, I'm happy with my 7D, but I'm expecting the D700 successor to be on par with D3s in noise or maybe slightly slightly behind it.

The Improved AF is expected, how much improved, time will tell...

[Anastas]

If 5D Mark III remains with DIGIC IV processor, I think it will be really disappointment. This camera must be with DIGIC V, to have cleaner high ISO and I think it's time to put 16bit color in the new generation cameras.
Also Canon can remove AA filter and fight the moire with software. Or they can leave a very tiny AA filter like the original 5D camera.

[baldusi]

I think is a dream of some fanboy. Canon would use a Digic V. And 6fps is not the objective of the 5D line. The 28Mpx seems logical.

[MK5GTI]

i was hoping they would have fulltime Video AF introduce, so that they can slowly introduce to the rebel line.

[Bob Howland]

It looks like a wish list to me. Actually, it looks like two, maybe even three, wish lists mashed together, one for a lord of darkness camera, Canon's answer to the D700/D3s, and another for a high resolution studio camera. If this camera is introduced before the 1DsMkIV (or a 50MP merged 1DMkV), Canon might as well simultaneously discontinue the 1DsMkIII.

[Bob Howland]

Also Canon can remove AA filter and fight the moire with software. Or they can leave a very tiny AA filter like the original 5D camera.

How does one make a "tiny" AA filter? Do you mean a "weak" AA filter perhaps? Also, as I understand, MF DSLRs don't use AA filters largely because of cost. Anybody who thinks that aliasing can be well corrected in software simply doesn't understand what aliasing is.

[ronderick]

oh my... not 2CH...

That's like the biggest anonymous gossip website in Japan.

While you might occassionally get a leak or two from undercover industry employees, I won't bet
my money on it.

btw, the last line of the source (the anonymous guy who started the thread) says:

"以上、妄想でした" 

[scalesusa]

The specs actually sound realistic.  There are always those who think they might get $8000 features on a low cost camera, it just won't happen.  Canon does not let features suddenly upward on a model series, they make incremental changes.

I'd like to see improvement in the Auto and Av settings though.  Specifically, the option to change the default shutter speed from 1/focal length to a settable ratio.  This would fix the auto ISO as well, since ISO would rise or fall according to the shutter speed ratio, and in effect, be changing the minimum or maximum limits depending on lens focal length used, at least while in auto or Av mode.  It might help in Tv mode too, I haven't thought much about it.  Right now, I have to use full manual, or set the ISO to get fast shutter speeds in Av mode.
