Minolta 200mm 4.0 MD I

Minolta 200mm 4.0 MD I on Sony A7



Minolta 200mm 4.0 MD I. A telephoto lens from the seventies. This is not an apochromatic lens, so at any rate, you get a lot of color fringes at high contrast edges. The big question is: Are the chromatic aberrations correctable in Lightroom?

Clicking on a crop loads the whole image in original size. A tip for Retina display users: Zoom in 1.5x or 2x. Otherwise you are not really in 1:1 mode.
Images are developed from RAW files in Ligtroom 5. All adjustments are Lightroom standard (sharpness: 25/1/25/0).

Conclusion Minolta 200mm 4.0 MD I on Sony A7



f/4 is a little soft. f/5.6 is best! Sharpness is good. Of course, the edges don't get the same sharpness as the center. But it's good enough. The chromatic aberrations are well correctable in Lightroom. Please look at the corrected image below. You may need two or three minutes for correction. The lens is very well built to last for decades. You don't get that quality nowadays very often. Focussing is very precise but rather stiff. The reason is, you have to move a lot of glass. Advantage is, you won't misadjust by accident. Disadvantage is, you may not be fast enough to follow with the focus. Photographing quicker movements, I would use an AF lens. Despite Sony A7's focus peaking you don't get many keepers.
