Hey guys, last night my K20D went really crazy just wondering if anyone has had similar, thankfully I fixed it.
Was using manual mode with adaptall 35-80mm with the manual (non P/KA adapter) don't recall doing anything strange.
After one shot that turned out really strange, i noticed image count for card was like 3500 instead of 400 so i checked in the menu and it had set to 1.6MP and greyed out the selection menu!
I then noticed I couldn't select a shutter speed slower than 1/25th, powered down and back up - stayed the same. Swapped lens out for my kit one, stuck it into AV and no matter how dark in front of the lens wouldn't go below 1/25th again or in manual still 1.6MP. Tried it without my 4gig SD card in to see if that would help, nope.
so I swapped out the battery for a spare that was charged, really hoping it would fix it - no fix! so I was a bit peeved and starting to panic, I tried last resort of factory reset in the menus and viola! back to normal
The first battery was really low (0 indication) on the camera, I wonder what went wrong - I checked the contacts when I took the manual lens off to make sure none were stuck or blocked on the mount - all clean.
I thought possibly the tamron lens had turned on the adaptall mount while on the camera but i'm not sure if that would've done it.
