I've been offered a nice 17mm 2.8 in good condition, and for a nice price (i think) at 100$. I have been debating with myself about focal lengths, now that i've started a new system from scratch. With my Nikon gear i had both 35mm and 50mm (FF), i just never favored one of them. Both are just great, but my heart was always with the 50mm even though the 35mm was more practical most of the times. Now that i've been starting over with a new system, the dilemma arises again I decided that i absolutely will get the Oly 25 as soon as possible. But buying both 17 1.8 and 25 1.8 is over my current budget. At that price for the 17 2,8 that could be my affordable 35mm substitute when needed. Because i could really use the extra light compared to my 14-42. I've read a few reviews about the 17 2.8 and mst are not so positive, but it seems to be just the corner sharpness... i could live with that. I often shoot close range and wide open anyway. If i need to do some wide outside shots i could use the 14-42. So, whats you opinions on the Oly 17 pancake?
