I can't enter into the lofty realm of glass that costs thousands (pick your unit of currency). I can, like many of us here, look for those hidden treasure that may end up pleasing (or even astounding) us. A lens that you didn't get because others had already extolled its virtues....one that you stumbled upon...gambled on..or just said "what the hell..." For me, it has been the Hexanon AR 100/2.8. A nice copy didn't cost much...and I wasn't expecting much. A friend had given me his Hex 135/3.5 and it was ok....but...nothing really exciting. I immediately liked the size and feel of it. I really am attracted to metal body lenses......it is small, light with a nice silky focus. It balanced very well on the E-P2. The first shots I took were, to me, pleasing....sharp, contrasty, warm, nice bokeh. Subscribe to see EXIF info for this image (if available) I since then have had it on my camera a lot. This week I am sending it off to be CLA'ed (the aperture ring turns hard). All this for less than $100. Subscribe to see EXIF info for this image (if available) How about you folks.....any favorites?
