Since the introduction of the Contax Distagon 2.8/21 in the early 1990’s, the 21mm lenses from Zeiss have a long and glorious history of being some of the best wide angle lenses in the world. While the Loxia 2.0/35 and the Loxia 2.0/50 are refined ZM-Designs, the Zeiss Loxia 2.8/21 is the first Loxia lens that features a new optical design. Lets have a look if the Loxia 2.8/21 can keep the heritage alive. 31/05/17 Update by Bastian: I have been using this lens regularly for a year now and Jannik asked me if there is anything I would like to contribute to his review, so I added a few notes and sample images.
The Voigtländer 12mm 5.6 Ultra Wide Heliar is actually one of the lenses I bought a camera from the A7 series for in the first place. It is worth to mention though, I am reviewing the old M39 version here. The newer Leica M version is optically the same, although there are other differences – apart from the lens mount – which I will talk about at the end of this review.
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.
In this comparison I want to compare two very different lenses.
TheMinolta 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 ebay.com (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).
