Hi everyone. Currently have: Canon EOS Rebel Xsi with EFS 18-55 mm lens. I need to take rhinestone jewelry picture as shown in the picture but I am not very satisfied with the clarity of the jewelry. I need to clearly see each stones of the jewelry. Following were the settings: Shutter speed: 1/64 sec Aperture: F/5.7 ISO: 400 I am thinking of buying a macro lens hoping that I could get a better picture but wanted get some opinions on this before I make my $$$$ purchase. I read from other posts that 100 mm f/2.8 Macro lens was a good lens to take jewelry pictures. Is there any other lens that would do the job for less $$$? Thank you!
