Fun with Old and New Lenses

I wanted to try out both my 30-yr old Minolta 50mm prime lens and a new Nikkor 105mm macro, just to practice with both, not really to compare. But I thought these two photos of the same subject showcased the two lenses well enough to share. I like the warm, painterly effect with the old lens, though it does shoot a lot darker than I expected, given the aperture setting. The result of the adapter, possibly? The top photo was shot in bright sunlight at f5.6, 1/125, ISO 100 and I still had to lighten it a bit with the curve tool in Pshop. The 105mm photo was shot aperture priority at f8, also ISO 100.

An adapter will cause the focal length to be slightly longer, thus affecting the aperture as well...You might have had the aperture ring set @ F5.6, but the true aperture wasn't the same since aperture is determined by the ratio of focal length to aperture diameter & since the adapter adds length, it changes the effective aperture..

Thanks, Scott. I'll have to remember to set the aperture 2 stops lower, or, more likely, shoot a lot slower with that lens. Must go experiment ...
