Since I got my Alpha 7 I have re-discovered shooting with very old Minolta Rokkor manual focus lenses. This is really fun but still quite difficult for me. So some days ago I went on a short walk to test my "Minolta MD Rokkor 28mm/2.8" wide angle lens. I use a Novoflex MC-Nex adapter to mount the lens on my Sony Alpha 7 camera.
The weather was not really good: It was a little foggy so the sky was a featureless grey. But it was not foggy enough to get nice fog shots. Anyway, I wanted to try this lens, so I took a couple of pictures.
First I made some deep focus pictures because this is really easy with a wide angle lens. Although everything in the next picutre is in focus, the picture is quite blurry and a lot of details are missing (click on the picture to go to flickr, where you can get to the full resolution image). I still include the picture here because all of the photos of this football field turned out to look like this.
Maybe this was my fault. Maybe I shook the camera. Or maybe the JPEG lost some details (the JPEG conversion of the A7 received some harsh criticism on other sites). Or maybe it’s because wide angle legacy lenses don’t work well on digital sensors. Or maybe the lens does not perform well at f/22. This is not a comprehensive test, so I assume it was my fault. But I don’t know. Anyway, next time I test a lens, I will shoot in RAW mode.
The lens produces very nice pictures wide open. The bokeh is a little bit nervous in high contrast areas, but still OK - at least in my opinion.
When stepped down a bit, the bokeh is really nice. Also, the pictures are quite sharp. I think I shot this at f/5.6 but I am not 100% sure anymore.
Here is a shot with lots of colors and contrast. It also has some out-of-focus twigs in front of the scene. I can’t remember the exact aperture anymore, but it was neither wide open nor completely closed.
I bought this lens on ebay for 30 Euros. At this price point, it is a really nice lens. Even though some images where rather blurry and the bokeh is nervous in high-contrast areas. The build quality is solid: Metal, Glass, a little bit of rubber. Yet, it is quite small and light. Manual focussing is really easy with this lens (and focus peaking & magnification on the Alpha 7): The depth of field is relatively shallow, so it’s easy to “hit” focus. And contrast is good enough for the peaking to work well - especially when you stop the lens down a bit.
It is a moderate wide-angle lens, very well suited for landscape and city photography. And for 30 Euros, I would buy it again - but I guess I would not pay much more than this.
Here are some more shots from the photo walk.
