Here is a shot taken on a Canon XSi. Mounted is a Leica R 60mm Macro-elmarit f/2.8 type 1. This is possibly my favorite lens in my kit. It is very useful not only for macro (as the example picture should show) but is a great prime lens all-around. I will post more example photos from this lens as time permits.
This is shot outdoors at Rochester, NY's Lilac Festival. It was particularly windy out so I had some trouble taking macro shots. This is the best of the bunch, I feel. It is shot wide open at f/2.8. Shutter is at 1/250 and ISO is at 100. The Leica lens does not report aperture to the camera body so EXIF states f/2.0 but it is really at 2.8.
