This lens was made in many different camera mounts but here I have it in Olympus OM. It is a true macro lens providing a 1:1 ratio. I loaded my OM-1 with Fuji 400 film in order to get a little more speed over the 200 ASA I typically use. That one stop can mean the difference between a sharp image and a blurred one. For example while typically you can hand hold a 55mm lens at 1\/60 sec that isn’t necessarily true with macro. The reason is that small amounts of movement are magnified at close distances, while an angular shift of a degree has little effect at 100ft it means an entirely different view at 1 foot. Of course a tripod would be a good idea ordinarily but in this case I either hand held or used a mono-pod. As you would expect with a macro lens it is very sharp and has very little distortion. <\/p>\n

My only wish is that it were in K-mount so I could use it with my DSLR, I really can’t find any reason to fault it, on the OM-1 it performs great and I was able to use it as a normal lens too.<\/p>\n\n\t\t
