I was very happy shooting with an Asahi Pentax MX, which to my eye was giving me very good exposures.

Then I had to have it serviced (for some other problem) only to be told that the shutter speeds were all in need of adjusting as they were all out.

This has now been done, and there is very little if any apparent difference in the result.

Go figure
