Albeit the 6D is 4mp less than the 5DIII
2 mp not 4 (20 vs 22).

I don't know what this is doing on a Canon forum!

You don't?  Here's a hint...

as usual another expamle that shows how much canon sensors suck at DR and pushing shadows.

and yes i would love to have that clean output when i do backlight shoots... it´s a matter of real world shooting not taking pictures with a lens cap on....
Did you bother to think that the images should be normalized to 12Mp in order to not compare apples to oranges? Sony would still be better but the difference would be smaller.

In addition you haven't seen a 5D3 with ML... (DUAL ISO feature).

Lenses / Re: Why does a 2x TC lose 2 stops?

The reverse is also true: A 0.5x TC gains 2 stops.

Those are usually sold as speed boosters to use a full frame lens on a crop camera. If i recall correctly, some lens designs with a wide angle and a large aperture have such an element built in.

In astronomy terms, I think these gadgets are called "telecompressors". I used one on my Celestron 8-inch to reduce the EFL from 2000/11 to 1000/5.6, or something like that.
I do not know if there is such a term but there isw a term reducer. For example I do have a Celestron 0.63 reducer.

I'd maybe suggest treading water for a while and see if a 6d mkii is on the horizon.   

Didn't the 6d come out better the 5d mkiii?  And the 5d mkiv is rumored to come out in 2015...,  So maybe they sneak a 6d out beforehand...

Now you're just being cruel  ;)
6D came after 5DMkIII. So 6DMkII may come after 5DMkIV. Now the 5DMkIV has not even been rumored yet. Good luck waiting  :P

I would get the 24-70 II. I am sure the 7D will have much more noise than 6D at high ISO but you will be perfectly happy with your 24-70 II at low ISO. A noisy sharp and correctly focused picture is better than  a clean out of focus image.

Just my opinion.

How about adding in the specific comparison a 5D3 with ML?  :)

I believe we will see a 5DMkIV, a 6DMkII, a 1DxMkII before we see 100-400 II. Not to mention a 7DMkIII  ;D ;D ;D ;D

I would like to ask CR if this proves yet another BS to refrain from mentioning it again and to stick to more plausible rumors please.

100-400 II rumors are good only for laughing!

10K? No way. A 135 format DSLR should not cost 10K. For that price I'd expect at least medium format. If in fact any camera maker made a body so feature-rich that the 10K price tag is justified, it means the camera will have 150 advanced functions that will be useless to me. 200fps? Max ISO at 1,000,000? DR of 100 stops? Ultimate, but totally useless.
MMMM, if Max ISO 1,000,000 means a super clean 25,000 or even better 50,000 and if DR was 25 stops (not necessary 100) then that would be a camera to pay for  8)

P.S 10 fps would be enough too.  :)

I do not want to tempt you but now how about the new 400mm DO II ?  OK maybe I do want to tempt you...  ;D ;D ;D

Not particularly tempted.  Yes, the 400/4 DO II is slightly shorter and a bit lighter than the 300/2.8 II, but the differences are pretty small.  The 300/2.8 gives an excellent 420/4 and a very good 600/5.6, and importantly f/2.8 for indoor gymnasium shooting (currently with my 70-200 @ 2.8, I'm often at ISO 12800 already).

If the DO II is as sharp as the 300/2.8 then by the same argument it should give a excellent 560/5.6 and a very good 800/8 i.e. in a small package replacing two or even three expensive heavyweights further up the lens chain.

But it's still f/4 at best....
If you are at 12800 already then indeed the 300 2.8 is the best choice. Unfortunately as you increase focal length (from 200 to 300) you will possibly need to increase speed too. As a result ISO will have to go up even by a little. In that case granted, a 400 4 would be much much worse. I guess it all comes down to the shooting circumstances.

I found that the maximum sharpness on a 60D was at F9... and F8 was very close to that. Above and below, it fell of. I still say it is a bit soft if you don't step it down.... but honestly, don't we all try to use whatever lenses we have in their sweet spot?

Generally, yes.  But f/9 is getting pretty narrow when you also need a fast shutter speed.

It is definitely a great lens, and superior to the existing 100-400 in the overlapping range..... but I do expect a new version of the 100-400 would reverse that, although at several times the price....

The 70-300L is also better than the current 100-400 in the overlapping range; between that and the 600 II, I had pretty much stopped using my 100-400, so I sold it.  I'm not even certain I'd want the new 100-400, I might just get the 300/2.8 II as a 'portable' option.
I do not want to tempt you but now how about the new 400mm DO II ?  OK maybe I do want to tempt you...  ;D ;D ;D

Lenses / Re: Canon EF 70-200 f2.8L IS II pricing and feedback
« on: October 27, 2014, 07:43:40 AM »
Just the same as last year. Canon would like to increase sales but they are a little greedy on price...

Just my opinion.

Apparently the new 100-400 looks likely to be a scaled up version of the Canon 70-300. What a shame - a scaled up IF version of the 70-200 would have been better.
That would imply that it would be constantly at its max size. For a 100-400mm lens that would be ... big. Bigger that 400mm 5.6L (compare 200 2.8 with 70-200 2.8L IS II to see what I mean)

It is coming in November ouaou. Is it November 2017 or November 2021 though?  ;D ;D ;D ;D
