Originally posted by imtheguy Just tried it for you. In Program mode, default in menu is "Normal", using a FA50/1.7 lens in daylight, using either wheel to change settings, I could get the aperture open only until sutter hit 1/8000, which is exactly what I would expect. When I pointed the lens towards shade, I could open the aperture to f1.7 w/o maxing the shutter.
If you are not maxing the shutter then have you changed any settings for Program from defaults?
Yeah, just tried it as well with my K-5 and FA43, also in Auto-ISO.
If I'm pointed at a bright light source and my aperture is already set to a relatively narrow setting (say f/8), I can't widen it beyond what gets the shutter speed to 1/8000th.
However, if I aim at a dark area and change the aperture to f/1.9 I can then shoot at f/1.9 no matter how bright my subject is (though of course the 1/8000 is flashing like crazy in the viewfinder and the shots are waaaay overexposed).
