Re: Tamron 150-600mm Reviewed - Returned
So here are the images from the other night. Il repeat so you don't have to go back through the thread
The images all look sharp at this resolution if you go on flickr you will get a better idea links to the albums are at the bottom.
It was good contrasty light so it was good conditions to try the lens out.
I wanted to try some of the points addressed in the thread. BIF, 400mm F5.6 with native expansion AF. 600mm F6.3+ with bird flying toward and horizontally to see if the AF struggles in either. All shots taken hand held.
I had the 5DMKIII set on 1/2000th to reduce 600mm issues, F5.6-8 1600ISO using centre 9 point expansion and case 6 for subjects that change speed and move erratically and lastly IS OFF because of the firmware issue.
Firstly 400mm F5.6 1/2000th 1600ISO bird flying toward and horizontally.
Images have been processed in lightroom, cropped roughly 30% 60 sharpening added (no mask as I would usually target sharpen) and 15 noise reduction

As you can see out of the 17 frames only 2 dropped focus so 88% in focus, the bird was flying fairly well and in a predictable manner which also helped. I found I had no trouble with 400mm in numerous flybys even when the subject was highly erratic.
one caveats - with the lock button engaged at 400mm there is play which equates to 428mm with the smallest of movement. Anything over 400mm moves the aperture to 6.3, I found that i had to hold the zoom function as it would move and found about 1/4 of my shots where I had moved hand position had come out at F6.3 and the hit rate dropped significantly.
Here is an 8 shot sequence of 400mm at F6.3, same settings as above just F6.3
Again images have been processed in lightroom, cropped roughly 80%

As soon as you go over 400mm where the native F is 5.6 the lens does start to struggle a little. 3 out of 8 shots being missed here with the Bird flying towards the camera so 62.5% in focus this time. But the bird was a little distance away and on a more fussy background.
Onto 600mm, here is an 12 shot sequence of the bird flying towards. F8 this time to aid with DOF at 600mm 1/1600th 1600ISO

As you can see it has tracked reasonably well, 6 shots are out of focus and 1 or 2 of them I put down to change in direction by the bird and motion blur. So 6 out of 12 50% in focus, but if we discount the 2 frames 66% are in focus. Again as talked about earlier in the thread the 600mm sharpens up well and I haven't really sharpened aggressively it will take 100 sharpening no problem but I'm at 60 here. The 600mm images are certainly softer but at F8 they look good. Again as before the ones in focus have that instant look of being sharp but delve a little deeper and they aren't quite tack.
Anyway here is the last series, horizontal flying bird but not really a predictable flight path bit of a test.
600mm F8 1/1600th 1600ISO

This is a perfect example of my claims throughout the thread. The images seem to be just a touch OOF, 5 out of 10 50% now maybe I'm being a little harsh and they are fairly big crops. The camera is tracking the bird but its just not tack.
This is my findings of 600mm, I think you won't see much more than 60% of images tack in a sequence which can mean the difference between getting that moment where the wings are perfect and not. Although it does vary the last set of images the light was starting to fade and the bird was moving a touch, if the shutter speed was raised a little to 2000 maybe 2500 it may have done better, but these gulls don't move that quickly and it was a little erratic but compared to other birds they aren't the most erratic so 1600 should have been fine.
There were a few instances where it performed better, against blue sky with the light in front of the subject for more contrast. I do have a 63 shot sequence where it seemed to perform very well but its too much to post.
So 400mm very good 8-10 400+ more around the 6-10. I think I'm improving also, its not an easy focal length to use. Its certainly taken me a while to get to grips with it. But like I said its not a lens you can just put on and expect good results from you have to think about what your doing, select the right settings especially shutter speed.
I think if the firmware was updated and I could have used the IS it may have helped but maybe not with those shutter speeds.
At 400mm its very sharp and quick but the play in the lock switch is a real pain and can quickly get frustrating. It also helps a huge amount if you use back button AF, I got much better results than the first time I took the lens out.
