I've just tried moosing around with a reverse mounted 50mm to do some macros.

Nice pics... Any chance of a pic showing how you mounted it?

Its made from a nikon adaptor screw mount for an old mirror reflex lens I had years ago. The lens vanished but the mount turned up in a box of film and batteries I had in the shed. I taped an old UV filter to the front of the mount using insulating tape so that the female thread faces outwards. Trim the edges of the tape up with a stanley knife to expose the filter threads. Its then possible to screw a lens onto the UV filter and mount onto the camera.
The Focus ring doesn't work, as the focus mech moves the lens elements relative to the barrel of the lens. When the barrel of the lens is normally mounted to the body, this moves the lens elements relative to the film plane, hence changing the point of focus. But by screwing the front of the lens to the body, it fixes the lens elements to the body and the distance to the film plane, and the focus ring just moves the lens barrel around. Focus is done by moving the camera relative to the subject.

Depth of field as normal is by lens aperture. Smaller aperture = greater depth of field in focus, and because its macro its really the only way to get anything in focus. Because the lens aperture control arm is dangling in free space, the lens aperture is controlled by aperture ring on the lens so will stop down as you stop down the lens. Normally the camera holds the lens aperture open so your viewfinder is bright and then releases the aperture as the mirror comes up before the shutter opens.

That means you need to compose an image with the lens open pretty wide, so nothing is in focus but you can see roughly the composition and get a bit of an idea. You will need to get close, probably 10-15cm from the subject, which is always frustrating with a tripod.
Then just set the shutter speed in manual, stop the lens down to f11-22 and play around to get the right exposure.
It only works with lens which have a manual aperture control so Nikon G lenses and I imagine the newer canon lenses won't work.
Extension tubes would probably be an easier way to get a similar reproduction lens, but I don't know how far you would need to jack the lens out by.
Also, don't grab the camera by the lens as you pack up as the UV filter slips out of the tape and your camera hits the deck. Luckily I made it to the bedroom before this happened which is the one room in our house with carpet.

Nice selective colouring, and raw is a ton better than jpg if your doing any post.

I had a play with soem macro options a while ago wrote it up here (part 1):

Reversed lenses are messy espeiclay on canon with no aperture control, tubes are OK, proper macro lens is ofcourse the best option.

Looking for some bellows though.

:D Thanks! Will print that out and take it with me next time I'm up that way..

In other news I managed to get a great deal on a tamron 90 macro at the weekend... Seems a great macro and a decent potrait lens too.
