More Sigma 70-200 2.8 II HSM Shots

I think there are several forum members debating between this lens and the Tamron. I went down to a park by my house yesterday to specifically take some shots at 200mm/F2.8 which is one of the conditions that DPreview in its review of this (non-K mount) lens was critical of.

1. ISO 200 200mm/2.8 on Monopod No PP

Original


Crop:


Judge for yourself, the review indicated softness at these settings... Pretty sharp to my eyes...

The review also mentioned significant CA at these settings. In all my shots yesterday at these settings I did not see any CA, EXCEPT when I added the Tamron 1.4 Tele

2. ISO 200 200mm/2.8 + 1.4TC on Monopod no PP

Original


Crop


So on the crop - I do see a bit of green along the top of the beak, but nothing too bad I think!


And a quick note on using the Tamron 1.4 with this lens. It seemed to want to focus past infinity a sometimes as I could here kind of a "clicking" noise as it focused out...

No - not 100% - just cropped around animal for sure. Will post one at 100% (When I figure out how to do that in Lightroom - When I Zoom out to 1:1 and then press the crop tool, it zooms back out...)

Ok - I still am not sure what represents a 100% crop - but here is the duck cropped a lot more! Perhaps a 'tiny' bit of CA on the highlights on the beak.

100% crop means that if you're gonna show your picture at e.g. 800 x 600 then you take a sample from the picture that's 800 x 600

doesn't look too bad here, but hard to tell for sure if it's because the duck is moving.
what was the shutter speed ?
