Holy Hell. I've been out shooting with the 5D3 and I just have to say that the IQ rocks. I think I love everything about this camera except the reach. Personally, I think it knees the 1D4 in the groin. Now, if they could just give me this level of IQ with a 1.6 crop, I would be a happy man, though I think it'll probably be about until the 7D Mark III until we get there.
I think it's more been that they've been limited by processing power, since processing only cares about total MP count and not density, than not wanting high MP on FF, I think. 18MP on APS-C or FF requires the same processing power. But 48MP on FF takes a LOT more processing power than 18MP on APS-C (48MP is 18MP APS-C density scaled to FF).
nuther related note, I think processing requirements go up somewhat if people also select in-camera hi-iso NR. Sure can slow down the shooting speed if I accidentally turn that on... clogs the buffer faster anyway. I reduce in-camera overhead with all processing off, raw only, no jpgs either... unless I need really long bursts at full speed then raw gets turned off and jpg compression to minimum.
if sensor density goes up, not only does the size of the data array increase but the required noise reduction processing going on, even for the raw files, will add a bit more overhead compared to a larger pixeled (lower noise) sensor. Yet another reason to wish for less sensor noise at all sensitivities.
The ff guys talk about IQ
The crop guys talk about reach
The APS-H guys get it in the neck from both
I like me a good APS-H body! I hope the used 1D4 market takes a dump once the 1Dx comes out. Too bad Canon got rid of the 1.3:1 sensor. It really is a great compromise between the APS-C and FF extremes.
All four lens that don't work exhibit the same behavior - it just locks up the camera after one shutter actuation. It never actually takes the picture.
Yes, that's exactly what happens to my 5D III. I replied to Kenko with list of lenses that did not work, and I just got their reply, which is not encouraging since it does not seem like they even want to look into it any further despite multiple user reports. So far I have not seen 5D III owners who report that ALL their Canon lenses work with Kenko, yet Kenko reports their 5D III body copy works with all the lenses. Hmm, is it possible that Kenko's Japan version of 5D III is fine but U.S. version isn't?
Thank you very much for your reply.
We have checked all lenses you mentioned with Canon 5D Mark 3 and Teleplus PRO300 DGX 1.4x Canon.
And we haven't any problems in these combinations.

more to the point any news on finding people that are actually going to buy them?
I may be tempted to get on of them for video...not sure yet. WOuld have to try it and see some reviews, but I do a lot of family video with my 24mm. I like primes but if it was IS on top of it, I would look into it. Though I have other lenses on my hit list first, like the new 24-70 II.
I'm seriously considering selling my 2 580EX II and my 430EX II so it'll be a little easier to afford 3 600EX-RT and a ST-E3-RT.consider just getting the phottix odins
