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

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.

Sample Images

Meopta Meostigmat 50/1.3, 617-inspired 1:3 crop out of 3:2 full frame image.
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).
Meopta 50/1.3
The Meyers date from the 1930s! This 50/1.6 cost someone 6 pound sterling in 1938, according to an old advert.

Review: Minolta MD Zoom 75-150mm 1:4

The Minolta MD 75-150mm f4 was released nearly 40 years ago but still it makes a good argument for a category of lenses which has nearly died out: Zooms with a limited range and slower speed.

Beginner’s Guide to Manual Lenses on the Sony a7

Okay, everybody is talking about how manual lenses work so well on the Sony a7 series but how does it actually work? And which results can you expect? Read on if you want to know.DSC00720

Manual Lenses on the Sony a7/a7II/a7III

Zeiss Distagon 2.8/28  ~ $250
Olympus OM 2.8/100 ~ $100
 Minolta MC 1.4/50 ~ $60

Why should I use manual lenses?

    • They can be very cheap, you can get a great 1.4/50 lens for $50. For most applications such a lens will give you 90% of the performance of a $1000 Zeiss 1.8/55 FE. For the $1000 you would have to pay for that Zeiss you can buy an excellent set of five lenses from 20 to 300mm.
    • You have a huge choice between thousands of lenses ranging from exotic ones with lots of “character” to some of the very best lenses available.
    • There are 30-year-old primes with better image quality than many modern lenses. Of course progress has happened in recent years but still affordable primes are often sharper than very expensive modern zooms.
    • Old lenses are usually beautifully built from nothing but metal and glass which makes it a joy to handle them. They can last a lot longer than modern lenses which are full of electronics and very complex designs, both of which make them more likely to fail.
    • They also hold their value much better than modern lenses. With some patience you can sell most manual lenses without a loss but with new lenses you can expect to lose 30% in the first year.
    • Manual focusing can be very enjoyable. This certainly depends on application but personally I enjoy working with fully manual lenses a lot more than with any AF lens and I would choose a good manual focus lens over an AF lens (almost) any time.

Review: Contax Zeiss Vario-Sonnar T* 4.5-5.6/100-300

Contax Vario-Sonnar 4.5-5.6/100-300 mounted on my Sony A7III via Novoflex NEX/CONT* adapter and with Novoflex ASTAT-NEX* tripod collar.

The Contax Zeiss 4.5-5.6/100-300 T* MM is a telephoto lens that hit the market in the mid 1990’s. It was also one of the last lenses that were designed for the Contax/Yashica mount. It is rare because it was very expensive in a time when autofocus telephoto lenses were already available. Lets have a closer look at this exotic legend.

The Nikon 35mm f/2.8 (affiliate link) is a relatively small 35 mm  legacy lens. Although it has some weaknesses it is currently one of my favorite lenses. In this review I discuss the strengths and weaknesses of this lens.  Most sample pictures can be found in this Flickr album.
