Ok so I'm trying to understand something. The lower the focal length, the more magnification you get? I want to buy one of those reverse rings. There are tons on ebay for $20. Should I get one for my 50mm f/1.8 or for my 18-55mm kit lens (been sitting in a box for 3 years lol). Thanks for any info, I'm excited to step into the world of macro!!!!!
Just found the two I needed for $3.99 each, shipped on eBay. I bought a 58-52 (for the 50mm 1.8 plastic lens) and a 52-49 (for the old 28mm). Now I need the EF adapter, $5.78, and I'm ready to rock and roll. Those prices are including shipping!
I don't think I'll be reversing the 50mm 1.4 yet, but it's 58mm and so are the old zoom lenses.
Of course if I want to get fancy, I'll have to dive in the dumpster for a plastic chili bowl and some old aluminum foil, because I wouldn't want to spend the 10 cents on buying them? 
Not macro, but eventually I'd like to connect my EOS to a telescope using the reversing ring and a 1.25" tube. Not sure if I can do that with the reversed lens, or maybe a bunch of step down rings and some machined parts.
Mating the lens mount to the tube is going to be the difficult part, unless I can find an old back lens cap and make some plastic adapters for the 1.25" tube.
Is there a way to calculate the distance that I will be shooting at, or is it just a matter of looking through the viewfinder and seeing when it's in focus?
