Since I started getting photography I wanted a macro lens. When I was in school I couldn't afford one. As I got older, I just had other things that I had to spend money on. Thanks to ebay, I finally got a macro lens. Here's a shot of my Yashica MAT-124 TLR camera with my new Sigma 90mm f2.8 macro lens.

This shot was made with existing light at f2.8 shutter 1/125 with an ISO of 1600. You might notice that the field of focus is very narrow in this shot. That's because of the f-stop of 2.8. A narrower f-stop (or aperture setting) would give a much wider field of focus and would make the foreground and background of the shot sharper. In this, you notice that where the lens says "3.5" that the "3" is the point of focus. The decimal and the "5" are right on the edge of sharp focus.
