ownership:I own this lens
compared to:minolta 50 2.8 macro
price paid:60€ (2nd)
positive:cheap, sharp, no minolta colours but OK, did i say i got it nearly for nothing?
negative:it seems like a cheap lens, makes a lot of noise - but it's ok, it's just the construction.
Slow AF
comment:For the amount i paid, including the 1:1 macro add-on - i could've bought worse. It's absolutely fantastic plastic.

If you don't need a 100 macro often and you want one for the occasion - get it, you won't regret it. But try it out on your camera before buying (for the AF) - to see if you are feeling ok with the af-speed.

The AF is not fast, rather very slow - it makes lots of noise (i was warned it sounds like falling apart) - but it's ok - that's something i can live with - i'm not after the most spectacular macro fotographs & flowers don't run away...

For more than occasional use - there's better on the market - both the Tamron 90mm and the good ole 100mm 2.8 may be better suited.

It's wrong to compare it with a 50 f2.8 - but it's the only other macro i have. So it's a good thing to have - if you know what the limitations are.
