First of the regular roses of the season...

For this photo I used the manual focus 90mm macro lens with an AF
adapter that is default set at f2.0. I shot this photo (AV setting) in
shaded sunlight at f4.5 actual at 1/4000...with this setup you can
manually set the aperture but the exposure is mainly through the shutter
speed, as the camera thinks it is at f2.0.
