I photograph products (amateur for the firm I work for) for printing in a small brochure that is commercially printed. I use 450d and 50mm 1.8 mk2. This I find gives better results than the standard kit lens. I use Elinchron D-Lites. Exposure is always F8-F11. Camera and lens is not used on anything else.Outside I use a Canon A630. Recently I have been photographing some greeting cards with textured finishes but when photos (RAW) are taken into Photoshop CS5 on 27" imac - no detail is showing of the finish. Another photographer/competitor has photographed similar cards and the amount of detail he obtains is incredible. I know he uses a Sony with a Nikkor lens. My question is would the Canon 1.4 50mm give me a noticable improvement over 1.8. I have done a lot of checking on the web but to be honest I am now confused. As already mentioned camera and lens will only be used with flash at F8-11. Many thanks for any advice.
