I really liked the shrike and the tern. Very impressive with a 2xTC on a 7DII. The bokeh behind the blue wren is a bit rough, but maybe other lenses would have the same problem with such a background.

Are they 100% crops or are they reduced in size and cropped? If reduced, by how much.
Jack Douglas said:Bo, interesting to see the effect of sharpening side by side. While there is an apparent appeal of sharpness improvement, the more I looked the less it seemed to really have benefited. Just me??
I really appreciate these various CR threads.

Bo said:I´d like to show a couple of pictures from a shooting session with European sparrow Hawks hunting along a sand reef. covered by reed and some small water puddles and low bushes. The hawks were mostly flying just above the reed or ground/water. In order to stay hidden I was sitting down and could only se the hawks during e few seconds the last 20 meters as they passed me.
To me this foto event showed the very good AF function with the 7Dmk II and the lens. It wasn´t possible to use a tripod nor to use anything else but automatic selection among all the AF Points. A bit like shooting trap! Still I got my best Hawk pictures ever.
The two first are with the 400DO alone and the two last with 1.4 ext III.

Is seems that getting a lens to use primarily with a x2 TC is not a great idea (if not for IQ, then definitely for AF). If I thought I was going to need to use a x2 on the DO a lot, I'd probably suck it up and get a 500 f4 to use with a 1.4. Both size and weight of the DO really appeal to me though - I will be hiking with it.

I have to sound a note of disagreement. I use the 2xiii (and occasionally the 2xii) on the 500LII and it works fine. Not as fast or as sharp as with the 1.4x but still very good (albeit not fast/erratic subjects like BIF). It's worth stopping down from f/8 to f/10 to have optimal sharpness (on the 5DIII at least).

While there is no doubt the X1.4 is preferable if reach isn't needed the X2 III is well worth owning. There are many CR examples. The only time for me that the AF with the 6D was too slow was if focus was lost completely and it had to recover. If a bird is identifiable within the viewfinder it snaps virtually instantly. Not the best for BIF for sure but that's what I used for my pretty acceptable eagle shots this spring on the 1D4 (300 2.8 II X2 III). Loose the bird for a moment and the shot would be lost due to searching, so the trick was to not hit back button focus unless the bird was under the focus point.
One thing that is hard to come to grips with is the reality that IQ keeps climbing with each generation. Take the 7D for example, since it was a very popular birding camera. Should all the 7D shots be canned because the 7D II is significantly better. It's tough if you tend to be a perfectionist and look at the technical details more than the artistic merit. My head says no we should not denigrate shots that are not up to the latest highest technical level and yet there I am focusing on sharpness just like everyone else, I guess.
Think of paintings. Are the only good ones those that have every feature displayed to the utmost degree of sharpness? So what gives?

This looks perfectly sharp even if it was shot at f/8 so fully open. Did you sharpen it on post? I also see that you used relatively low (1/250) speed although you shot at 800mm with 7DII. Did you used a monopod or very steady hands ? (I guess the IS is very good but up to now I do not rely on it very much - this will have to change...).candc said:this is taken with the 2xiii on a 7dii. cropped and resized with dxo
