Projector Lenses – Part 2 – Adapting Old Petzval and Projection Lenses to Modern Cameras

Image November 9, 2025 Mark Stein 9 Comments

The best thing about life is that sometimes there is a cat. A close second is characterful lenses to depict it. The Kowa 50/1.3 is a more common optical design than old Petzvals, thus its rendition is closer to, say, a Canon 50/1.4 M39 or FD, but with busier bokeh.

As many readers asked for and looked forward to a follow-up to the Projector Lenses article—one that explains how Mark carried out the conversion and offers some hints and guidance so you can try it yourself—he kindly put together this second piece on the subject. All photos and text are by Mark; the article design and layout are by me, Martin.

So, I’ll hand it over to Mark…

Welcome back! This post seeks to introduce you to the possibilities of adapting old 16mm-film projector lenses to Evils, SLRs and even Rangefinders. The aim is using these old treasures for creative photographic expression. But whilst the charm lies in the resulting pictures more than the resulting object, feel free to wake your inner fine mechanic! Mine has definitely been fast asleep, and yet, through immersion, I graduated from first putty attempts to a solid interchangeable mount setup, the recipe of which I’ll share.

So here we go, I guess.

Interestingly out of the big camera manufacturers of the (D)SLR era only Nikon ever produced a 28mm 1.4 fullframe lens. They started in 1993 with the world’s first lens with these specifications, the Nikon AF 28mm 1.4D, and then released an updated version in 2017, this Nikon AF-S 28mm 1.4E. It was one of their last f/1.4 primes still designed for DSLRs, so let us find out what it is capable of in this review.

Projector Lenses – Reviving the Joy of Old Petzval Lenses (Guest Article)

November 2, 2025 Mark Stein 19 Comments

Introduction

Martin recently reviewed Lomo’s replica of a Petzval lens. I commented, perhaps slightly snidely, that vintage Petzval lenses are still around, often for less money, and often with better centre sharpness – and certainly with a vast choice of models and thus rendition nuances.

Martin suggested I share my knowledge in an article. And like an inverse Spice Girl, one became two. This one seeks to introduce you to the weird magic of Petzval lenses and their widespread availability from old cinema film projectors. The next will look at adapting them, and indeed any old projection lens, to a modern-day camera.

So here we go, I guess.

All pictures were taken on full-frame evils: a Sony a7r2 and an a7cr. Some were cropped; all were adjusted for proper blacks and whites according to ancient darkroom principles. None had additional sharpening or aberration correction applied.

Meyer Görlitz Kinon Superior 50/1.6 – A characteristic of Petzval lenses is the swirly bokeh, which also results in lentilesque distortion of highlights (some call it cat’s eyes; you’d need a pretty deformed cat to see that analogy).

The Meyers date from the 1930s! This 50/1.6 cost someone 6 pound sterling in 1938, according to an old advert.

The Sigma 105mm 1.4 DG HSM Art was one of Sigma’s last flagship lenses designed for DSLRs and one of the few that hasn’t seen a successor designed for mirrorless cameras yet. If you read my review, you know it is an impressive lens, but I still had some reservations calling it the “Bokeh Master”. Now I get the feeling someone at Sigma read my comment and decided to take it as a challenge by designing this Sigma 135mm 1.4 DG Art – the actual “Bokeh Master”. To me, this is one of Sigma’s masterpieces, so let’s have a closer look!

Review: Viltrox AF 85mm 2.0 FE Evo

The “Evo” series is a new lineup of Viltrox lenses positioned between the “Pro” and “Air” lineups. This series seems to combine the build quality and controls of the “Pro” lenses with a slightly slower maximum aperture like the “Air” lenses while maintaining very high image quality – similar to the Voigtländer Apo-Lanthar series or Sigma’s Contemporary primes. Let’s find out what the first entry of this series – the Viltrox AF 85mm 2.0 Evo FE – has in store for us.
