I got this lens with my camera when I first bought the camera. I wanted a lens that I could take more zoomed, detailed photos with, and I knew the standard lens on the camera wouldn't allow me to do all this.
The lens resulted in some amazing photographs: great clarity, amazing detail, everything I wanted in my photos, but then the trouble with this lens came.
About a year after I got it and started using it, I noticed that EVERYTHING I focused on showed up dark in my camera. I had it looked at by a camera repair man/ professional photographer, and he discovered that the problem was in the lens. When you put this lens on the camera, everything shows up extremely dark, losing detail and quality of the image, as well. What you saw through the lens is what came out in the pictures, and at the time, it was extremely dark.
I loved this lens while it lasted. It made wonderful photos.
