    One of my favorite things to shoot is macro.
    I would almost be interested in shooting even closer (micro?).
    But I’ve got this problem where I have to put the front of my glass about 2-3 inches from my subject. I think it might just be an artifact of the fact that I’m using a screw-on macro converter connected to a 14mm lens… is it? Don’t be too harsh, I’m poor and said converter was like $50.

    As the sig says, I have an Olympus E-500 so I’m a little limited in my lens choices as well as limited by the fact that they all cost a bazillion dollars.

    So does anyone know a good 3/4ths macro lens that can shoot from more like a FOOT or two away and doesn’t cost an entire month’s pay?

    All schooling, advice, and cries of “Noob!” accepted. (Noob)

    You’re going to need something like a 180mm or longer lens to get that kind of working distance. I don’t know how that translates to the olympus 4/3rds land, but that’s a pretty long lens. (And comes with its whole other group of problems, shooting-wise. My 180mm macro drives me nuts). Your best bet might be to get a nice telephoto and look for macro filters that lower the minimum focusing distance.

    Ok. Show and tell time.
    Here’s a few examples (which got shranked and exif stripped because I use free photobucket)
    First one is 14mm and front of lens is about 1 inch from the subject.

    Second is 45mm (about 3 inches from subject. I take blame for camera shake)

    Third is 100mm (about 6 inches from subject. Some wierdness that I DON’T take responsibility for.)

    Last one is 150mm (8 inches from subject. REALLY hard to focus, the AF couldn’t get it at all… so I set it to “max” which should be infinity but with the macro filter on it’s really really not. I opened up the fstop to 4.5 which is wide open for this lens and then moved back and forth until I found this kind of “sort of” focus.)

    er… ok.. so my img got snipped for some unknown reason…
    So in order…

    NOOB! (it never gets old)
    Is it possible your lens and/or filter is getting fogged up and/or catching light from the side?

    I had very similar problems when I was holding the front my lens steady with one hand, the camera with another, and focusing with another.

    I have nothing technical to add. I just came here to say that I love the way you write. 🙂

    Three hands huh?

    I always was suspicious you were an alien, with the stapler obsession and all.

    A hood might help a bit, but I think that’s mostly optical aberration from using a strong closeup lens wide open – stopping down 3 or 4 stops might help quite a lot (but would also require a tripod or flash unless you’re shooting in bright light)

    I have noticed something similar. I have a +10 diopter macro filter that I use occasionally. It works decently on the Kit lens 18-55mm But if I put it on my 70-300 it quickly gets unusable. I always assumed it was a limitation of using a macro filter instead of a true macro lens. Also with that much magnification, you are going to want to shoot with a tripod and remote release if at all possible.

    You need a lower diopter on a longer lens – a +3 or so would probably work a lot better. For a given diopter power, the magnification increases with the focal length of the main lens, but this also increases the optical aberrations in the system.
