I read this Tutorial
and found it in Tutorials section but wasn\'t sure if I posted there that I would get an answer, as the last posting was 2007.

I have a Canon Rebel xTi [400D]and I am interested in trying this macro photography, using equip. in above mentioned tutorial.
I have a
Canon Zoom EF 75-300 mm 1:4-5.6 III [58mm]
a Sigma Super wide II 1:28 24mm [52mm]
I know I need a reverse ring and a step up/down ring but, I am a little unsure of the ring sizes I need and where I would get them.

Thank You

I don't know about the specifics of your setup, but if you comment in the discussion thread for the tutorial, that thread should come back up onto the front page; maybe copy your question there so that all relevant questions/discussions stay in one place.

58 mm reversing ring from Adorama

You will also need a 52-58 step up ring, or some combination that will get you there (when you do this, you won'y always be able to find a single ring that will work, and you'll have to use multiples. For instance, I've never seen a 52 to 72mm step up, so you use a couple that span that same distance). Also be aware that some lens combinations work really well for this and some do not, so it's always a bit of an experiment. You might get significant vignetting at certain zoom distances.

Lastly, you will likely have to utilize a bit of an odd way of setting the aperture on the reversed ring, owing to Canon lenses lacking aperture levers. Mount the lens on your camera, set it in aperture priority or manual. Select whatever aperture you want, depress the depth of field preview button. Then, while still depressing the button, remove the lens while the camera is still on. The blades will be locked down whereever you had them set to. This will enable you to achieve more depth of field, however, it will also make the viewfinder much darker ALWAYS because your front reversed lens is perpetually stopped down. Metering should work fine, but you may need a flashlight to see what you're doing. Also keep in mind your focus distance is going to be very different than you're likely accustomed to, so I would suggest you mount the camera to a tripod and move an object towards your lens to get an idea of what your new focal distance is. It will likely be a few inches.

Good luck- shooting with reversed lenses is an interesting experience and takes a bit of experimenting to get used to. I'd suggest you either use a tripod and non-moving subjects or you use a supplementary flash and prepare to utilize lots of patience while you crawl all around the ground.
