The Voigtländer Ultron 28mm 2.0 is a quite small wide angle lens with Leica M mount. You may look up the specifications here on the official homepage. The lens is a quite modern design and has been introduced around 2012.

It is one of my favorite lenses on the A7s. Phillip read my reports about it and asked me whether I would like to write an in-depth review about it.  Hopefully, at the end of this review, you will know why I like the Voigtländer 2/28 so much.

Test: $20 Minolta MC 1.7/55 vs $1000 Zeiss 1.8/55

55erIn this comparison I want to compare two very different lenses.

The Minolta MC Rokkor-PF 55mm 1:1.7 was introduced in 1968 and it was always an affordable lens. Today it usually sells for around $20 at (affiliate link).
I like it because it has very nice bokeh, the nice focusing feel and the small size. I is not one of my sharpest manual lenses, the Canon FD 1.4/50 for example is noticeably sharper but it has very nice character, not far away from the much heavier and more expensive Minolta MC 1.2/58.

The Sony FE 1.8/55 ZA was introduced 45 years later in 2013 and it costs around $1000 or 50 times as much as the Minolta. It has received very positive reviews and is considered to be one of the best normal lenses available today.

The question I try to answer with this test is: How different are the results I can expect from the lenses? I will look at smaller images optimized for the web but also at 100% crops to judge print quality.

All images are developed from raw and I used a tripod unless I mention otherwise. Please click on them to see them in full size (1500px wide).
