REVIEW: Carl ZEISS 28mm f/2.8 Biogon T* + 1.5m pcx filter

The Contax G 28mm Biogon was considered one of the best 28mm available on film, but suffers serious issues on digital due to sensor cover glass. Can a simple filter make the lens a competitive performer on Sony cameras? Find out below.

I have shot this lens for years on the Sony A7 and more recently with a PCX filter and then on a Kolari UT modded A7. Unless otherwise noted, all of the tests in this review were performed on a Sony A7RII with a reversed 1.5m PCX filter on the lens (Thanks again to Nehemiah for lending me the A7RII). Check captions on sample pictures to see what camera was used. Bonus: The Contax G 28mm Biogon is both Phillip and my favorite lens on aps-c cameras, so I will also add a second installment later reviewing the lens for aps-c provocatively titled How the A6000 + Contax G 28/2.8 is better than an RX1.

Review: Canon EF 2.8/200 L II on Sony a7rIII

Introduction

There’s a gap in the Sony FE lens lineup that I find particularly irksome. There’s no AF 200mm f2.8. I don’t know when one will come either, because this is not a popular set of specifications. The lens makers think that you will buy a 2.8/70-200 zoom. But not only are they very expensive, they are very large and heavy. I would personally never carry one for the work I do, though of course many do, and many pros need to.

So what to do if that fast zoom is too heavy or expensive? I decided to have a look at a venerable and highly regarded Canon L series prime lens, the EF 2.8/200 L II. Adapted lenses work better than ever on the A7rIII, so it seemed like a good time to try it. Will it fill the gap, or should I be hoping for a Batis or Sony G?

Review: MS-Optics Aporis 135mm 2.4 Fluorit MC

The Aporis 135mm 2.4 is the latest and also longest lens made by MS-Optics, a one-man-lens manufacturer. It even features one of Canon’s famous CaF2 Fluorit glass elements, which is mostly used in their great super tele lenses for minimizing color aberrations. Does it help to actually combine fast maximum aperture, small size and good image quality?
