Sigma 70mm F2.8 EX DG Macro A-mount lens review by derekw
|derekw#9085 date: Jun-4-2011|
flare control: 5
|ownership:||I own this lens|
|compared to:||Minolta 50 & 100 f2.8 macros|
|price paid:||250 GBP|
nice weight - gives the camera good balance
|negative:||Screw in hood.|
Makes a lot of my other lenses look very ordinary.
|comment:||Very good macro and portrait lens.|
Useful focal length.
The ratings say everything else - no CA, no distortion and very sharp even at f2.8. Noticeably sharper than the Minoltas at F2.8, but once stopped down it is difficult to split - they are all extremely sharp.
By the way, mine works fine on alpha 33, as does the 18-250 and my older 17-70
