I used that same lens for a while & got some really amazing results from it. Some really sharp pictures. I can't remember off hand exactly how it works, but I'll check it out this evening when i get home to refresh my memory & let you know what you need to do. One thing I do remember is that you need to close the locking ring before you take a picture.

in the meantime take a look at this: http://michaelguo.com/blog/uploads/peleng.pdf

If I remember correctly you need to choose your F-stop setting on 1 ring, then you need to chose your distance from the subject on the other ring - the distance from what you want to be in focus. Closest focus point is 8mm.
Make sure camera is set on manual and always ALWAYS always makes ure the lock/unlock ring is turned to the LOCK position before shooting or the picture will be out of focus.

Try this & let me know how you get on.

There's really nothing difficult about it. If you're not familiar with using manual lenses, here's what the Peleng site says:
Working with M42 lenses acknowledgement of the focusing with green light is not made. The aperture is set «0.0». Expo-modes:
1. P (program) – identical to Av mode;
2. Tv (flash priority) – doesn’t work;
3. Av (diaphragm priority) – works as usual;
4. M (manual) – aperture and flash are changed. Inaccuracy of exposure defining is indicated by expo-correction.


All this sounds like a lot, but the basic is the same as other manual lenses. Use the AV setting, and you'll set your f/stop by hand. Then the camera will automatically select the appropriate shutter speed for you. If your images are blurred, it's probably because either:
1. the shutter speed is too slow or
2. you didn't manually focus.
Focus, and open the lens up (change your f/stop) until the camera sets a speed you can hand hold, or raise your ISO to compensate.

When you get some shots posted, please let us know. :wink:
