so, a while back I picked up the Oly LensCap. I liked that it added no depth to the camera, and thought it would be good for some street shooting , which I believe it is , but I'd rather use my Trip 35. I also thought I could use it with my telescope. Eh, not really. Sort of, kind of, but nothing great. Well, it does have one redeeming value. It works great at night on long exposures. Well, I say great, you may say very good ( or not ). If you have one, try it. See what you come up with.
