I have some extra money in my pocket. I don't know if I should upgrade to the Maxxum 9 or buy a Maxxum 200mm f/2.8 lens. Advice?
Glass is the most important part of taking pictures (well, aside from the photographer). Everything else just supports it. The 9 won't get you better pictures (in all but a few, extreme circumstances). The 200 2.8 will, especially 8x10 inch prints.
