Is it possible to create extended exposures using a m42 mount lens?
I just received a SMC Tak 50/1.4 and pentax adapter. On my K20d the only acceptable settings are Av and Manual. The exposures all look fine except when I try to adjust the shutter speed. I always get over-exposed images when I leave the shutter open for more than 1 second. (Even with f/16)
Am a missing a setting? I'd like to be able to take photos of water with extended exposures using this lens.
Thanks for any feedback.

That's a 10 second exposure.
The Takumars are the same as any other lens; you have to use a shutter speed and aperture combination that is appropriate for the amount of light coming into the camera. If you want longer shutter speeds and you've already closed the aperture down as far as you can, then your options are to lower the ISO and/or use ND (neutral density) filters. The above photo was done with an ND8 (kills three stops of light) and a linear polarizer.

Same filter setup, but as this was in a shadier location it is a 30 second exposure.
