I really want to do some monkey macro photography. I am a student with almost no time and money, and want to take some hobby pictures in my spare time. I have the Canon EOS 450D (Rebel XSi/Kiss X2). My lenses are Canon ZOOM lens EF-S 18-55mm 1:3.5-5.6 IS 58mm and Tamron AF 70-300mm f/4-5.7 Di LD Macro 1:2 Both with Auto and manual focus. Both without manual aperture. I bought an extension tube and 58mm reverse adapter ring for the EF-S 18-55mm canon lens but as you can guess, I can't control the aperture. ( I will try to modify the total €7 tube and ring so it will work ).
Next I have this nice looking SMC Pentax-m 1:2 50mm 5539731 ASAHI OPT. CO. JAPAN I want to use as my reverse macro lens. Inside of my lens cap it says 49mm, on my lens it says 50mm. I just can't find the reverse adapter ring for it. Can someone please help me? (found the reverse adapter. It is 49mm)
Image can be found here of my Pentax lens: image of Pentax lens
After some more searching, I've found a 450D macro reverse ring for 49mm lenses. I will buy that one and see if it works. Do you guys think it will work?
