what would be better in your opinion? first or second option? i know 70-200 + TC gives more flexibility but how about IQ or AF speed? whats your point of view? thanks.
thanks guys. i was thinking about shooting mainly wildlife, slow birds etc.
intersting alternative: 70-300 L + TC. I wonder how this would be performing in terms of IQ?
There's also the 70-300mm L which may be worth considering. With a 2x, that would give you up to 600mm.
I would not get a 70-200 4.0 with TC you will not be impressed as you'll never be able to achieve any sort of shutter speed that can produce sharp images. You'll be tied to a tripod taking pix of things that do not move to get any thing sharp.
I have the 100-400 and a 70-200MkII and TC1.4III. Never went for 2X TC as no one has ever had high remarks about it but I do see Pros use it with long primes. For best IQ a 70-200 is a superb bit of kit. I would also say the 200-400 will be a excellent lens when we get it in market and it's 4.0 for the whole range. The 100-400 is dated and while I enjoy the use of it in my bag it does not have the IQ I expect from the 200-400 or that I get from the 70-200. I never find myself using the 100-200 range of the 100-400 only the longer end of the lens. I would not get a 70-200 4.0 with TC you will not be impressed as you'll never be able to achieve any sort of shutter speed that can produce sharp images. You'll be tied to a tripod taking pix of things that do not move to get any thing sharp.
Notwithstanding the aforementioned 2.8 MkII with TC III is the better option of the two you are considering.
is 400 prime a possibility? Affordable second hand......

cheers Thomas.
I was considering prime 400 f/5.6 but sometimes when birds come closer I might need something around 200 or 300mm. its a bloody hard choice. I know if I buy one lens I will be unable to buy another one for next 2 or 3 years(unless I'll sell first one) so need to make wise decision![]()
did anybody tried 100-400 with 1.4 TC? as Richard suggested i've checked thedigitalpicture for sharpness and it looks good to me.
I've tried my 100-400 with the Canon 1.4 II TC on the back. The viewfinder did seem noticeably darker, but it still produced great images.
New 70-200L 2.8 Mk2 plus Mk3 extender runs it very close indeed.
Go to TheDigitalPicture and load up any combination of comparisons you like, including Mk2 and Mk3 extenders side by side. Here, this link should take you straight to it. Toggle on the little arrow in the middle http://www.the-digital-picture.com/...meraComp=453&SampleComp=0&FLIComp=7&APIComp=0
AF speed is an interesting question. Extenders increase it, but then the Mk2 lens is so fast anyway... If I was betting, I would guess the 70-200 plus Mk3 extender (completely new design, better in every respect) would still be faster than the naked 100-400L.
Really?
You know what I mean.

And maybe it matters if you can do the push/pull focus if the 100-400 rather than just the twist if the 70-200.
too slow and only manual focus = not for me, but it does "work". Although I will say that when I used this combo at Oulton park I used live view and zoomed in to focus and came away with a couple good images, not great but good. I would say it was not a normal set up or shoot but I got a couple images during the masters event last month
I was just taking general shots, nothing like motorsport where speed was an issue. I've not tried the tape trick yet, might give it a go next time.
You know what I mean.
