Did some extra testing today. Conspicuously absent were the 28mm lenses in the wide-angle department so I made up for that today. And I did some standard and telephoto tests; not as rigorously as the wide-angle tests, partly because across-the-frame sharpness is less important to me there and partly because I got fed up with testing. Have to do some zooms too, but that's for another time. Minolta MD W.Rokkor 28mm 1:2 Minolta MD 28mm 1:2 Minolta MD W.Rokkor 28mm 1:2.8 There isn't a lot between the 28mm lenses featured here. Both 1:2 lenses are a bit too soft and flary wide-open and need stopping down to f/2.8 to get good center sharpness and contrast; the 28/2.8 is already good wide-open. All lenses are great in a fairly large portion of the frame at f/4. I'd say that the MD 28/2 needs stopping down to f/8 for good corners and the Rokkor 28/2 and 28/2.8 need f/11 for that. I think I'll prefer the MD 28/2 as a 28mm lens in my bag, but I won't use it a lot probably. Lately I got to find this angle of view a bit boring and I tend to use 24mm more often (16mm on the NEX-6, that is). Minolta MD Rokkor 50mm 1:1.4 This lens is a long-time absolute favorite of mine for landscape work, be it on the Panasonic GH2 or the NEX-6. On the A7 it has about the same characteristics: wide-open all the detail is there across the frame, but is very soft and flary, really dream-like. Stopping down gradually expels the softness towards the corners until they are fine at f/8; on the NEX-6 this lens is perfect at f/4. Nice lens, but not exactly a low-light weapon because of the need to stop it down substantially. Minolta MD 85mm 1:2 I knew already that this lens works well wide-open. There is some glow around highlights, but not enough in general to spoil the pictures. Stopping down to f/2.8 gets rid of the glow. Didn't check corner sharpness, but made some test shots to see how the out-of-focus areas look like. Not buttery-smooth, but not very bad either. I think I'll use this lens next weekend when my daughter gets her master's degree; have to practice this week! This lens never really impressed me on the NEX-6, but it really comes into its own on the A7. Minolta MD 100mm 1:2.5 This is a lens that works very well on all formats (µ4/3, APS-C and FE). On the A7 it's sharp across the frame right from the maximum aperture. Bokeh looks OK too, check the pics of the grass. Simply excellent lens. Minolta MD Tele Rokkor 200mm 1:2.8 Just a few hand-held shots because light and motivation were fading . Not too shabby, just as on the NEX-6. This lens makes really sparkling pictures, Minolta at its best. That's it for now, time to start making pictures again!
