Tamron SP AF 90mm F2.8 Di Macro A-mount lens review by tmoreau
|tmoreau#974 date: Jul-3-2006|
flare control: 2
|ownership:||I have experience with this lens|
|compared to:||Tokina 17mm f/3.5 ATX Pro|
|positive:||Incredible image quality, 1:1 macro|
|negative:||Dosent handle extreme conditions well, poor autofocus|
|comment:||I have the non-di version, Superb image quality, best of any lens I've used. Clarity, color, sharpness, when the conditions are right this lens just 'pops' like no other. |
Flare can be very bad, night street scenes are not even possible with this lens because the whole scene washes out badly. Sometimes a problem indoors with a window in the scene, etc. I've only seen purple fringing once or twice with a backlit scene, but it was very bad. Glad this is a rare occurance.
Autofocus is fast at standard ranges, I use manual focus for macro. In some conditions autofocus is unusable, it hunts and fails to lock on (usually indoors, combination of low-light and close ranges?).
When used for macro I have not seen these issues (except for occasional overexposure), very good performance here. Works great from wide open.
