Re: Sigma 70-200mm f/2.8 DG DN OS Sports for Sony E and Leica L
Finally Damien's review (sorry it's in french) who does compare the Sigma DN with the Tamron G2 and the Sony GM2 :
A few take aways :
- Image Quality :
a) Sharpness is very close with these 3 zooms (he had to go through 200% magnification to see small differences).
Interestingly (or not), he saw a slight better sharpness of the Sigma vs GM II in the corners at 200mm wide open.
Closing the aperture and we won't see any difference at all.
b) Bokeh : GMII and Sigma have a better bokeh than the Tamron (portaits with trees in background) and bokeh shapes are slightly better than with the Tamron.
- AF success rate on moving sujbect towards the photographer : Tamron and Sigma have a very similar succes rate. GMII is better.
- Stabilization : he does confirm Gerald's analysis and does state that Sigma stabilization is even better than the GMII stab.
- Tamron & Sigma zoom and focus rings have a reverse position vs GMII (not good handling/ergonomics).
- Build quality : Sigma and GMII are clearly ahead of Tamron (in terms of build materials quality, internal zooming -> whether sealing).
GMII has off course all the bells and whistles (TC compatibility and speed limits, internal focus breathing compensation, ...you name it)
