I am having issues with an A 100mm macro.
I overexposed in A mode, as if it didn't work in A mode.
Results are perfect in M mode...
I thought it was the K20D, then it worked on K10, now it is doing it again on K10...
How could this be fixed?
Thanks
Sounds like your aperture blades are sticking. Check that by manually opening/closing them a bunch of times off camera - if that's it, you can take it apart yourself or have Eric do it for about $30 plus shipping charges.
