Ernotar Ernemann 150mm f/4.5

Satisfied with the purchase This is being used on a Pen F with a MMF-2 adapter. Optically, it's very good. Autofocus is slower than the real micro 4/3s lenses, price was right and I usually manually focus anyway. The Pen F has some focus aids which really help and it's hardly slower than waiting for the autofocus to settle. All of the 4/3s adapted lenses have this problem with the micro 4/3s cameras I have, not unexpected. This particular item wasn't used heavily, wasn't in new condition but very good cosmetically, no scratches or dents but a little dinge on the operating rings that cleaned off. Everything operates smoothly and wasn't loose. It's shorter and lighter than the adapted Nikkors I was previously using in that focal length range.

Bad purchase! My fault. Thought all Olympus 4/3 mounts were the same. Not so. Does not fit my Pen E-PL6! May be a perfectly good lens, but I’ll never know. The lens even has the micro 4/3 logo on it but in actuality is much larger and heavier than my current Oly micro 4/3 40-150mm. Not a good value to me, but could have been an excellent value had it fit my camera bodies. My bad.

This is an awesome little lens for the price Pros: -Beautiful, tiny, and light -300mm equivalent on Micro Four Thirds bodies -Pretty sharp throughout the zoom range; even sharper if you tinker with sharpening in the raw files -Focus is very quick -It can do beautiful macros, as it is close-focusing Cons: -You have to buy the hood separately -It has a relatively dim aperture at 150mm, requiring high ISO or slow shutter in dim light
