Sigma 17-70mm F2.8-4.0 DC Macro HSM C A-mount lens review by fogfire
|fogfire#11385 date: Oct-13-2013|
flare control: 4
|ownership:||I own this lens|
|compared to:||SAL 18-250|
Older Sigma 17-70 (pre HSM) used to own that and this one is much better and that was one of the better zooms in this range.
|price paid:||499 USD|
|positive:||HSM focusing is nearly silent. |
Very sharp across the entire field. At 17mm widest the edges gradually do get softer.. But web tests and mine show it to be really sharp to the edges.. Compared to other lenses I have used in this range.
Size is nice
|negative:||Macro shots can take the lens front right up to the object.|
HSM does make clicking noise when stopping, starting, changing direction. This can be heard on video when shooting a low noise scene.
Overides a77 MF setting. AF/MF switch on lens has final say. This disables DMF but focus peeking still works.
|comment:||I wanted quieter focusing and sharper lens for my new a77. Had been doing casual shooting with A700 but want to do some more serious shots.|
