Picked up a Olympus IS/L B-Macro close-up lens. Got it for $25 with a case and a pretty useful flash diffuser that clips over the lens. Fits any lens with 55mm threads (or with step up/down rings) Works pretty good, mounted on a OM 200mm 3.5 it appears to get down to a little better than 2:1. Please note I was too lazy to mount on the tripod so these are handheld. Hopefully this weekend I will get a chance for a better quality comparison. Note the sd card pictures are resized not crops. I'll post a crop below. Micro-SD card sitting on top of a SD adapter Tokina 90mm 2.5 @ 2:1 for comparison.
