Hi All

I have the 7D and overall have been very happy with its performance using the 100-400mm ~ yes it can be a bit sluggish focusing in lower light conditions but has a high'ish keeper rate when shooting motor sports, airshows & wildlife.

However, I am looking to add full frame to my kit and the 5D3 gets very good reviews for the sort of subjects I shoot but not necessarily with the lens & TC combo I mention...............hence my question?

Does anyone here use this combo and though in focal length terms there is a drop of 80mm using the 5D3 (none TC lens on the 7D and using the TC on the 5D3) if a crop is needed to best 'frame' the subject in PP what sort of impact do you see/get

Many thanks in anticipation of your insight and user experience plus if you have links to any posted imagery do please point the way

For wildlife close-ups prefer 7D-100-400 L combo. Even 1.4 III teleconverter slows things down. adds weight. harder to handhold steady. have 5D3 too. prefer 5D3 without converter when "reach" is not necessary.

My opinion on this is that the 5D3 paired with the bare 100-400 (no TC) is better than the 7D paired with 100-400 even with the loss of pixels per duck unless you can keep the ISO on the 7D below 400 (i.e. very good light). Adding the TC on the 5D3 works but isn't great in the AF department and that lowers the amount of keepers. IQ holds up but not AF. Basically, the IQ of the 5D3 is allows for deeper crops to make up the reach of the cropped sensor 7D...IMHO.

Many thanks all for the feedback & insight...............food for thought and decisions to be made

@ arbitrage ~ I note that you are in Whitehorse Yukon, I have found out I have somewhat distant cousin who is resident there but not sure whether in Whitehorse. Will have to check with my brother because he saw them recently whilst they were this side of the pond.

Totally Agree...even without doing the math

Putting a TC on any variable aperture slow zoom can't end well. BTDT, shoot naked man.

So if you crop the 5D3 to the dimensions of the 7D and account for pixel density/pixel pitch how many MP do you have in the 'frame' presumably less than the 7D at 18MP but how many in real terms This question presupposes that such a crop yields an image "look" that is right as at the moment I do find myself cropping the 7D sometimes quite markedly but still get very workable images for print.

Box Brownie: You PM'd me -

Have you got any images to show with the 100-400 + 1.4x TC combo

If you have some links and any insight as to how well you find the combo 'works' especially in regard to Image quality compared to not using the TC and the responsiveness of the AF mainly in AI servo mode??

----------------------------------------------------

The combination of the 5diii and 100-400 and 1.4x works pretty well. I tried it last June when I went on a corporate trip and wanted to bring a camera but did not want to seem to intrusive.

Here are some examples shot from a moving boat with 1.4xiii 100-400 and 1.4xiii:

A pod of humpback whales came by. They were bubble fishing. I was reach limited with 100-400 on 5diii but put the 1.4x on anyway and gave it a try. first = 560mm, iso 800, 1/8000, f9. 2nd = iso 800, 560mm, 1/5000

http://stoness.smugmug.com/Family/Kinder-Morgan-Marine-Survey/i-gWGTRMx/0/XL/5D3_5488-XL.jpg

Similarly but in poor light a pod of killer whales went by, the big male in shore scaring the salmon offshore to the waiting orca. Again in poor light with reach challenge, here is the result. iso 1250, f9, 1/2000 560mm.

One last one 1/8000, very hard light almost shooting into the light, cranked to max 560mm, iso 800,f9 - you can see the herring jumping from their mouths

Hi Scott

Many thanks for those...............not much to complain about it in regard to image quality in those or the 5D3 performance in the ISO department

How did you find the AF compared to when only using the lens without the TC The reason I so to speak separate the IQ from the AF is that some reports of this combo said the AF suffered somewhat

Oh are these examples the full frame or (slight) crops?

Thanks again for sharing

Nice whales....

In a pinch, almost anything will work... it just would not be my 1st choice....

The 400 5.6L, OTOH works wonderfully with the 1.4 TC and resulting AF speed is decent enough even for slower, larger BIF.... IMHO, IQ is better than the 100-400 without the TC......

My advice: ditch the 100-400, buy a 400 5.6

I have the 200-400, 600v2, sold the 500 v1, 100-400, and 70-200v1. I would not recommend the 100-400 w 1.4x as a normal shooting practice. I think the focus performance is better than my 70-300 IS non L without the 1.4x but comparing my 600v2 with 1.4x on it, it is a tad slower and the iq definitely is decreased.

I think the question is what is your primary purpose that you want to use buy a 100-400 for. If you want a general purpose lens, safari, large animals, bring it with you everywhere, it is the best. My 200-400 has better Iq but much heavier and larger.

If you want a bird shooting lens, you will always be pinned at 400, so you might as well buy the 400/5.6. The iq is better and reportedly takes the 1.4x better and likely will focus faster. See:
http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=113&Camera=453&Sample=0&FLI=8&API=2&LensComp=278&CameraComp=453&SampleComp=0&FLIComp=1&APIComp=0

But the 100-400 w 1.4x performs fairly well on the 5diii. Just not sure about bird shooting.

However, I never bought the 500/5.6 because I shoot more of range of animals - bears, birds, moose and sometimes they come close.

My view is that if you have the 7d and the 100-400, 5diii, 1.4x and was reach limited, I would only use the 5diii if the light was limited (dawn and dusk or cloudy ) and use the 7d 100-400 otherwise. However I have noticed that since buying the 5diii I tend to use the 600/1.4/5diii way more and the 7d/600 less. I only resort to the 7d/1.4/600 when the subject is stationary and the light is good.

I am not sure if that is helpful. Given that I have the 600mm, I have not needed to use the 100-400.

P.S. Not said in the above postings - there were probably 1/10 that were sharp with the boat moving and the whales suddenly appearing, and the changing light conditions.

I use the 1.4x with the 100-400 on my 5D2 and I'm pleased with the results when atmospheric haze doesn't intervene. Even in winter there can be heat haze.

If it works like this, 100-400 with 1.4x Mark II on 20D crop factor camera, manually focused, then don't worry about the 5D3 and the improved Mark III:

I have both and agree with this view completely The 5D3 IMHO is a much much better camera than the 7D and I only use the 7D in good light or when I'm definite for reach. When Canon bring out a 1DX replacement I will replace the 7D

Thanks for insight & feedback................as for a 1DX, if money were no object :lol:

I believe you just divide the 5D3 23mp resolution by the 1.6 area ratio and come up with 14.3mp in an equivalent crop. Still pretty good.
