<p>I sure appreciate all the advise. I have three lenses. #1) a 0 with a line through it then 55 Sigma Zoom, 100-300mm, 1:4.5-6.7 UC. It has a red dot on it, has lock then A some kind of angle line the 32 22 16 11 8 4.5. #2) a 0 with line through it 52 Sigma Super-Wide II, 1:28, f=24mm, multi-coated, MACRO Sigma AF Super Wide A with angled line 22 16 11 8 5.6 4 2.8. #3) a 0 with line through it 55 Sigma Zoom 28-80mm, 1:3.5-5.6 MACRO, A with angled line 22 16 11 8 5.6 3.5. This has a slide switch to change from Normal or Macro at 80. Also says ASPHERICAL on it. I also have filters with it. #1) MARUMI 55MM C-P.L #2) TEFFON 5.5MM UV PROTECTOR. All my lenses have a red dot and there are also some pins like on it kind of at an angle down from the red dot. I wish I knew more but I'm not very good with these. I do appreciate all the help you have given already. If not that much I may get a 35MM and a digital that I could use my lenses on. I also have a cup looking device that I'm assuming fits on the lenses as well.<br>
Thank you all very much!<br>
