Dear all, I am not a very experienced NEX user, NEX 6 is my first mirrorless. I read on the forums that people recommend shooting in M or A or S mode when having an adapted Manual lens on. I have a manual Canon FD 50 mm 1.8 lens right now, however, if I put the mode to "A" the preview of the image that I am about to shoot is reasonably pretty accurate in terms of how it compares to the final image (brightness, color, etc) after I pressed the shutter. However, if I use the M or the S mode, the preview is completely off. For example, if I change the shutter speed to really fast the preview still gives a bright looking image but when I pressed the shutter, I would actually get a very dark image. Because of this I find it extremely difficult to use the S or the M mode. Is this normal or is there something wrong with my camera? Any input is appreciated!
