Sorry no blood and gore knock-out, just some peaceful rose bush shots. And sadly I didn't realize until later that I had been shooting at ISO1250. For your consideration please take a look at the following: Pentax SMC-M 100mm center @f2.8 Minolta MD 100mm center @2.5 Pentax @ f2.8 Minolta @ f2.5 Pentax @ f5.6 Minolta @f5.6 Sharpness: Pentax is clearly winning here, nice resolution wide open. The image really pops. That said the Minolta gives a nice soft glow that is considered a classic portrait look. Personally I'm not a fan of that look. I'd rather soften skin up in post process. Colors: too close to call for me, though looks like the Pentax is slightly warmer toned and due to the sharpness wide open it renders more distinct colors Bokeh: Mixed; wide open the Minolta melts the background away while the Pentax shows more bokeh fringing. However at f5.6 things have reversed. Now, with the Minolta you have more aperture half-stops between f2.5 and f5.6. Ergonomics: the focusing throw is longer on the Minolta. Minolta aperture turns the opposite way of the Pentax. That's fine either way. Portability: Here's the interesting bit. That Pentax is SMALL. Disgustingly small. It balances well with the A6000. The Minolta feels too lens heavy. So, there you have my thoughts on these two lenses. Either one is a good choice. It's the photographer that matters the most.
