Very nice, Sigma macro lense for Olympus mount; this lense will take VERRRY sharp close ups and is very well color-corrected. I have taken shots with this camera that impress the most persnickety photo-buddies I have.
I have used this lense for astro photos, and it does a good job as a mild telephoto; the color correction is very good, so there is virtually no false color.
Lense is missing a little bit of the silk-screened labeling, as seen in the pic, but other than that, it is in great shape. The coatings are beautiful and they have been protected with a 52mm UV filter.
I purchased this lense from KEH about two years ago for $275 and was not disappointed.
I will let it go for $200, shipped and insured in the lower 48.
Thanks for looking.
