flare control: 4
|ownership:||I own this lens|
|compared to:||Tamron 60 F2|
Minolta 100-300 F4.5-5.6 APO
|price paid:||120 EUR used mint|
|negative:||Built from toy-like plastics, however seems still OK after 3 years of usage|
Normally 1:2, for 1:1 there is a matched adapter
In some situations it seems the actual aperture or maybe light transmission is less than claimed, so need to correct exposure up a bit
Manual focus ring a bit tacky (no smooth turning), but still usable.
|comment:||I got the Soligor F3.2 variety.|
It has to be the cheapest macro lens ever and it is pretty good at that.
Pretty nice wide open with already sharp center, almost tack sharp by F5.6 as a whole.
The AF on my A580 body was spot on, but with A58 I get consistent backfocus. Which is strange, as other lenses worked OK on both bodies. Not much of a problem with macros - best technique is to focus manually or by moving the camera.
The 1:1 adapter is a bit of a hassle - it's a screw on type - so it takes some preparation, also the ability to focus larger distances up to infinity is lost. So I mostly use it without the adapter, unless for static subjects.
To sum up, it's no miracle, but you definitely get more than what you pay for. It's a perfect way to try macro photography before committing to a more costly lens. And at the end you might just decide this is all you really need.
