Hi everyone, I just bought a high-end Canon Digital Camera (full frame) so i figure its pretty ridiculous for me to be shooting on my 28-80 standard Canon lense that came with my Rebel 2000 (right?) So, now I'm thinking I should buy a Canon Professional lense (i want something that shoots wide angle, and I also want to be able to zoom to 70 or 80mm (i have another lense for 75-300 and I don't care that its not pro because im most interested in wide angle- 50mm) My questions are the following. what is the difference between standard and professional lenses from canon (i know about chromatic alterations, vignetting) but are the differences major. anyone have a used pro lense or know where i could get one? Also, should i buy a seperate macro lense or a complete zoom. i mostly shoot wide angle, like i said, but sometimes i like to zoom a bit. any thoughts? sincerely, joshua -- Joshua Soros Soros Photography and Installations Soros Web Developments 3241 Center Street Soquel, CA 95073 work: (831) 706-2-NET (2638) fax: (831) 475-8548 Photographic and Installations Art: www.joshuasoros.com info@xxxxxxxxxxxxxxx Web Creation, Marketing, Management & Commercial Photography: www.soroswebdevelopments.com info@xxxxxxxxxxxxxxxxxxxxxxxx Personal: josh.soros@xxxxxxxxx
