I dreamed of this lens for a long time to go with my G1, I was put off by the high price tag. After saving hard I decided to treat myself to this lens and I am glad I did as I am having a lot of fun using it both on auto and manual focus when photographing flowers and butterflies etc.

This is a very sharp lens! Great colors, very light weight, like many of the MF3ds lens's. Pretty nice portrait len's just a tad soft in the corners at 2.8, but can be fixed in post if needed or cropped out. This lens has one problem, focus.

"This macro lens give amazing optical performance. It is in my tests flat-field, just as sharp in the corners as in the centre, even at f:2.8, and consistently sharp from f:2.8 through f:9.

This is not a technical review, but more an everyday use description of a fun lens to own. I've used this lens several times now that the weather is cooler. This lens brings a whole new perspective to my photography in that I'm now looking for the smallest of details.

love it, great macro lens

Excellent seller, I recommend to all
