Reverse Macro question

smallm

I have a Canon XTI with 100mm Macro. What would I need to try reverse Macro. I do know I probably require 58mm for 100 but not sure what size needed for camera end.
Thanks for any replies.

1. remove lens from camera
2. reverse lens
3. hold lens to camera - I use large rubber bands to hold in place
4. snap away

You can buy threaded adaptor rings to secure one lense to another (front-to-front) from Ebay. I have one that allows me to mount a reversed 50mm to an on-camera 28-70mm. I did see some web material on the in's and out's of lens selection for reverse macro, but can't recall at the moment

I'm curious though. Why would you want to reverse your macro lens? I'm not arguing, just asking. When using a lens in reverse orientation, don't you set the focus to infinity for best performance. I don't know you'd gain anything reversing that awesome lens .

You give up so much when you decouple the lens from the camera. Unless you did it this way! But $480's a lot to pay for a reversing ring,

Sorry to dredge up this old thread, but does anyone know a source for these reverse threaded adapters? All the ones I've found on eBay seem to mount a lens backwards directly to a body. Maybe I'm searching for the wrong key words or something.

I'd like a male-to-male step down filter adapter. It will be used to mount a 52mm filter-sized lens backwards onto a 58mm filter-sized lens. (I know these can be made from scratch with step up/down rings and a bit of epoxy, but a solid ready-made one would be better.)

Just got back into the hobby with a new Rebel XSi. So I dug up my old 80's camera gear and rediscovered a 50mm 1.4 and a macro focusing rail.

They are normally called reverse macro couplers - eg like these on ebay http://stores.ebay.com/Camera-Ace-Photographic-Accessories_Stepping-Rings_Macro-Coupler-Rings_W0QQcolZ4QQdirZQ2d1QQfsubZ3QQftidZ2QQtZkm

Thanks very much! That item is exactly what I'm looking for.
