The Olympus OM 2/28 is the smallest manual 2/28 mm lens you can buy and in this in-depth review on the Sony a7II I check if it is still relevant in 2017.

PR: Dear Mr. Li, let me thank you for this opportunity to ask you some questions about your work and the process of designing a lens.
But first we would like to learn a bit more about you. Can you tell us a little bit about your background and your position at Laowa?

I have already reviewed the Canon EF 200mm 1.8 L and the rare Voigtlander SL 180mm 4.0 APO-Lanthar, but the Olympus OM 180mm 2.0 Zuiko Auto-T is even rarer. I guess most of you didn’t know it even existed.
The Olympus an exotic relic from the past, one of Olympus’ masterpieces when it comes to 35mm lenses. So let us have a look at what I think is the first and only review of this lens on a (high res) digital full frame camera like the A7rII.
The Carl Zeiss Planar 1,7/50 is reputed to be one of the sharpest normal lenses and also the cheapest Carl Zeiss you can buy. In this in-depth review I put it to the test.

Most rangefinder lenses used on a Sony a7 series camera show some serious issues because of the rather thick filter stack in front of the sensor. There are two ways to deal with this. We have previously discussed the use of front filters to counter the induced field curvature. In this article Sebboh reviews another solution.
This is an extended use review of the Kolari Ultra Thin (UT, also sometimes referred to as version 4) sensor stack modification on a Sony A7. This modification removes the AA filter and IR cut filter from a stock Sony camera and replaces it with an ultra thin 0.2mm thick IR cut filter in order to attempt to provide similar levels of performance to the Leica M9 in dealing with the steep ray angles often produced by rangefinder lenses designed for film. I have shot a UT modified Sony A7 for 6 months now and can confirm that it dramatically improves performance with certain lenses (big thanks to Nehemiah for letting me use his lenses and cameras for the comparisons shown here). I will try to outline what kind of improvements can be expected here and what drawbacks there are to getting the conversion done.
