Hey, just a brief plug here, but I am selling my Sigma 28mm f/1.8 lens in OM mount. Again.
The person who bought it from me ended up not realizing that there are two popular Olympus film SLR mounts, the OM mount, which the lens is and the Pen-F mount. He had a Pen-F adapter for his NEX and Zuiko 42mm f/1.2 and didn’t want “another big adapter to have to carry around”. sigh.
Anyway, it is relisted on eBay in case you are interested. It is a wonderful lens in great condition that I am sorry to part with, but I need the money with my switch to an OM-D E-M5.
If you are interested or have a friend who is, here is the auction listing. http://www.ebay.com/itm/150841576311?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 ($225). If you are coming from my blog omexperience and choose best offer on it, mention that you are coming from my blog as I am willing to cut a better deal and would certainly take readership in to account to.
