//feel free to add your own comments/images to the threadMy copy arrived yesterday with my dealer and I had a chance to pick it up earlier today. Unfortunately, I had not much time for more extensive shooting/testing, but thought you might be interested in some initial impressions (and RAW files).
The size difference to the predecessor is not that much. If the precessor would not be around, someone would be inclined to say - same size, same weight. Not much change.
From a build perspective it feels similar as well
Boy, the AF is fast. Can't say with the limited shots I did today HOW much faster it is, but is significantly faster (tested on the D5). Nice.
The flipped AF/focus rings. 2 obstacles: One is real, one is just a habit thing.
1) The habit one. Years of 70/80-200mm lenses had it in same position and given the frequent use, it becomes over time an automatic, subconscious thing. B ut the new FL E had it arranged in the same way like the AFS 24-120mm. Depending where you come from, you might need to adjust your habit. No problem in normal shooting, but more errorprone when fast reaction is needed - the old automatism is still in my way. I am much more often changing focal length than manually changing focus, so from this perspective the new arrangement is (currently) the better one, as long I am shooting slowly (to avoid getting in my automatism trap). I do thing this arrangement will be much better when you I follow a fast moving subject and I have to change focal length while tracking and shooting (i.e. an object moving diagonal as it closes in) - to be verified.
2) The reversed sun shade issue: This is the same issue like with the AFS 24-120mm. If the sun shade is reversed in the park position, it is almost impossible to reach the focal length ring without removing the sun shade. It might cost precious time in those circumstances, where the photog need to react fast and the sunshade is still in travel position.
If the fast AF required the reversal of the rings, then I prioritize the fast AF benefit over the experience reversal of the rings. Don't know, if the 2 things depend on each other, just in case.
AF accuracy was out of the box very good with the D5. Didn't do any AF adjustment yet. Similar experience as with the AFS 105mm/1.4E, it just works. Haven't checked outer AF focus field accuracy yet (the Sigma Art AF test)
Very nice and unexpected close MFD at 200mm, seems to be longer with shorter focal length (need to check this again)
A few first and quick images, just resized down to 1500x1000 to save NG bandwidth. Please use the filename under the image as index to the RAW files
in this directory, in case you wan't to check out the RAWs directly.
Photos:
1) Visible vignetting with f2.8
2) Same subject with f 5.6.
3) Taken at MFD (plus a few centimeters), f 2.8, AF+reframed
4) f 2.8, AF+reframed
5) like 4), but f8
6) Cat eyes on the border of the frame at f2.8
7) 200mm/f2.8 at 20m distance
8 ) Not sure where the reflections are coming from
9) 175mm/f2.8 at approx 50m distance
Next images will be nicer :-)
