Tokina 28-70mm F2.6-2.8 AT-X 270 PRO AF A-mount lens review by tankm
|tankm#1023 date: Jul-16-2006|
flare control: 3
|ownership:||I have experience with this lens|
|compared to:||Minolta 28-75 f2.8|
|positive:||Build. AF/MF clutch.|
|negative:||Heavy. Minimum focus distance of 700mm compare to Minolta 330mm. |
Sharpnest wide open (f2.8) is mixed.
|comment:||f2.6 not usable on the KM5D (not really important). Sharpnest at wide open (F2.8) is mixed, better at the wide side, and become soft around 60mm onward. Stepping down to f3.5-4 helps to regain the sharpnest at the long end.|
Only thing I really missed from the Tokina is the AF/MF clutch mechanism. When set at AF, the lens can be held anywhere without worry of gripping the AF ring. When set to MF, it provides a big grip, easier to MF.
Have to watch out for flare causing situation. Side strong light can cause flare on this lens.
