Turkey Vultures are common in central Texas, and these took a break on a dead oak tree to groom and dry out from the morning rain. I made these on an overcast morning from approx. 100 yards away using a tripod-mounted Q and an adapted M42 manual focus Super-Takumar 135mm f/3.5 lens (equivalent focal length about 750mm). These JPEGs are derived from the RAW files cropped to about 80% with some sharpening and basic enhancements. Considering the distance, they’re not bad although the limitations of this screw-mount vintage lens and the sensor “stack up” against any hope of technical excellence. This "extreme telephoto" adapted lens shooting can be fun, but with the original Q’s sensor, I’ll never expect anything better than long-range snapshots.
Pentax Q and adapted M42 Super-Takumar 135mm f/3.5, 1/320 sec at f/5.6, ISO 320.
I stopped down a bit more here to f/8 for the group photo.
Here’s a reference shot from the same camera location, at a “normal” focal length of 9mm (taken the next day). Note the yellow box showing the approx area of the adapted telephoto pics.
