Adapter: Novoflex MD-Nex
Used on A7r. My A7r arrived yesterday. I spent a considerable amount of time reading the useless instruction book and charging the battery. Then I had a small play with it.   I have a small number of MD lenses and one ( not the subject of this post) I held great expectations for immediately started to look like a disappointment. The high-hopes lens was the Rokkor 35-70 mm macro zoom. Just a few minutes with it suggested it just wasn't up to the task.. I played round with some of the others and when I fitted the 28mm wide angle I was amazed to find that images in the view finder just seemed to pop. This morning I went out side( just around the corner) and first tried out the 35 -70mm. Looking at the pictures I decided either it was my lack of skill, a dud lens or just not up to the A7r's resolution. So I threw on the 28mm went out again and despite my lack of skill and unfamiliarity with the camera I was still impressed with what this little prime was producing. I took three sample photos at F2.8 F 8 and F 16.   the first photo was over exposed. I would also have to say it was an overcast day just in the process of turning sunny. The sun was behind the camera. The only editing I have done to these photos is use the auto fix on each one. Any experts interested please analyse away and give your feedback on the lenses performance. Feel free to cut and paste the images if you wish to. Please ignore the composition. To get a good comparison I mounted the camera on a tripod and used a 10 second shutter delay.   Is this lens as promising as I have gained the impression it is?   

Shot 1 F 2.8 1/100 sec


Shot 2 F 8 1/40 sec




Shot 3 F 16 1/8 sec

Visited Bratislava yesterday and took the A7r with the 28mm. Both photos were shot wide open

I have recently been playing with this lens ( the first version, I think, with 55mm filter threads) on my A99 with an MD-MA adapter without glass. Can't focus to infinity but this adapter essentially turns the lens into a close focusing macro.

The details rival my true macro lenses (Min. AF 50mm f2.8 & Min. 100mm f2.8)

Adapter can be had for $10. An inexpensive road to macro.
