Focusing with a reversed lens (and metering)

[buurin]

I got a reverse ring for my 50mm. It attaches directly to the body of my 30d.

I went out to play with it and I found that moving the manual focus ring doesnt appear to have any effect in the viewfinder. I have yet to be able to review the shots on my monitor so I can't say for sure it had no effect.

So is the only method of focusing to physically move the camera? If so that means I simply cannot shoot certain compositions because they will be out of focus?

I think I know the answer to this but I want to know for sure. Thanks.

Also any tips for metering? Can I spot meter with the lens on correctly & apply the same exposure with the lens reversed?

Thanks

Hi - you are right the focus ring has very little effect, you need to focus by moving the camera. I do this anyway with my macro lenses it's the easiest way to ensure accurate focus. If you are on a tripod then a macro focus rail would be necessary.

Metering is done on the camera - I use evaluative mode in TV or Av modes for natural light shooting or just put the camera in M mode and use flash. You get used to using EC for natural light shots or FEC for flash shots to alter the exposure metering.

Hmm I could of sworn my meter wasnt working with the lens reversed. I had it set on spot & throwing my grey card up in front of the lens the meter didnt budge. I'll have to try again, I was in a bit of a rush.

Thanks for the confirmation and the info on the focus rail -- I didnt know there was such a device.
