My 100-400 II arrived today at the local store, collected it at 2.45 pm, adjusted microfocus on Focal by 3.45, when it was nearly dark here, ± 1.4xTC.
I fired 6 quick shots of the local chimney in the near dark at 560 mm (with the 1.4xTC) at f/8, iso 2500 and 1/25 s. All were spot on sharp. The IS is excellent, at least 4 stops, compared with 3 on my Tamron at 600. The image looks really sharp. I couldn't do any extensive testing as I had to photo all the kids at a Christmas party, but I have just done some quick shots of the centre of the iso 1223 chart to compare with the 300/2.8 II and Tamron on the 5DIII. (My 70D is at WEX being assessed for part exchange).
1. At 400mm and f/5.6, it is not as sharp as the 300 + 1.4xTC at 420mm and f/4. I was only at about 8m from the target, and the focal length appeared to be only about a real 370mm.
2. At 560mm and f/8 with the 1.4xTC it is really sharp, and much better than the Tamron 150-600mm at 600mm and f/8.
I am really surprised about how good it is with the 1.4xTC. With it's superb IS and performance at 560mm, I am really pleased I bought it. A little disappointed at 400mm, but maybe microfocus isn't quite right yet. I'll play around with it more in the next few days to see how it shapes up at 400.
Left hand side shots are raw converted to jpeg with no sharpening whatsoever. Right is applying unsharp mask at 0.9 px and 100%.
