    reverse ring help

    My reverse ring came, and it is right now. Any help someone can give me would be great, since there are no instructions with it. I put it on the lens, and put it on the camera. I got an error message that says lens is not attached. The view finder is black. How do I take a picture?

    You are getting that message because the ring doesn't provide electrical contact between the lens and camera. You will have to use the camera in full manual mode to take photos. I don't however understand why the viewfinder is black. Do you have the lens cap on?

    No, cuz the lens is facing the body.

    What about the lens cap on the other end?

    Nope, it was the cheap plastic one, and I took it off before I put it on.

    OK, I figured out that part of it. I had the appeture ring locked at f/22, so it was so dark. I set the flash to manual. but I can't seem to get some good pictures. Wow, this is a lot harder than I thought it would be. I just wonder how people get good shots. I have to hold the camera, and it is so hard to hold it perfectly still. I still have to figure out the shutter speed, cuz the whole thing is manual. :-(

    Any hints would be lovely.

    Have you considered camera shake? Look at the focal length you're using and multiply the focal length by 1.5, for the crop factor of your camera sensor. You should not try to hand-hold a shutter speed longer than 1/that number. If you're at 18mm, you shouldn't try to handhold longer than 1/27 second. If you're using your longest focal length, 1/200, you shouldn't hand-hold a shutter speed longer than 1/300 sec.

    Try to keep the aperture between f/8 and f/16 as much as you can, for best sharpness. And I'd recommend not using the on-camera flash ... better to shoot subjects in bright off-camera light.

    I don't think you're rule applies to this situation Toriaj? The reason why holding the camera still becomes a big issue in this case would have to be the reverse magnification factor - Imagine holding a slide with your fingers under a microscope; the slightest bit of movement is mangnified - similar to shooting at extreme focal lenghts 600mm +.

    aparmley, sounds like you're way ahead of me on this ... I don't really know, it was the first thing I thought of

    mugsisme, it might help if you posted a pic. Good luck

    I think a tripod and/or a couple of heavy bean bags plus a wireless remote should probably be your next purchases if you want to persist with the reversed lens.

    I've just got myself two reverse coupling rings that allow you to mount an inverted lens on the front of a regular lens.

    I'm currently experimenting with the 50mm f/1.8 reverse mounted on my 70-300IS, and am facing a similar problem of camera shake...

    From my diagnosis, the reason seems to be that with this setup, the 'focus distance' is so drastically reduced that the front lens element is effectively covering your subject and blocking most of the light, which results is slower shutter speeds leading to camera shake.

    I need to try more during the day in bright sunlight

    On the plus side, it gives you amazing magnification....

    You first see a photo with your mind, and then capture it with your camera!
