I recently picked up this asahi optical co. smc pentax-m 1:2 50mm serial 8285183
I slapped this on my camera to play around with today and am having an issue taking early evening indoor photos with flash. Even at F-22, with the flash up my camera's max shutter speed tops out at 180, with the flash down its 4000. So when I am taking pic's with the flash up, they come out pure white.
When I set up my promaster to the same specs, with the flash they come out very dark.
I am new to photography, so I am sorry if the answer is an obvious one.
There is more than one issue here.
1 When you use manual lenses, the flash ALWAYS uses full power.
2 Maximum flash sync speed is 1/180th. sec. This is normal. With a Pentax compatible external flash, you can use "high speed sync", which allows you to use higher shutter speed at the expense of range.
3 If your pictures are pure white, the diaphragm might be stuck wide open. Did you set your camera to allow use of aperture ring?
I can't say from what you describe which one it is, but one of your lens might be defective.
