Exotic Optics

Allan Walls


Macro photography is unique in a number of ways but one feature that makes it particularly exciting for me is the almost infinite variety of special optics that can be adapted for use at magnification. Macro lenses are, of course, purpose built for close-up imaging and, as you would expect, they run the gamut from  terrible to superb, with most falling somewhere in the middle. But what is even more interesting to me are the specialized lenses, usually designed for some specific purpose other than macro photography, that can be adapted for use as macro lenses. Some examples include optics designed for use as scanner lenses, close-up diopters, bellows lenses, enlarger lenses and a host of specialized industrial lenses. In each of these categories there are lenses that perform particularly well when adapted for macro. But there are a handful of lenses that really deserve to be placed in a special category all on their own because they set the standards by which other lenses or lens combinations are measured. These are the lenses I want to talk about this week and I call them Exotic Optics.

Exotic Optics is a somewhat arbitrary designation and you will see it used to describe lenses like Laowa’s probes, Nikon PC (Perspective Control) tilt/shift lenses, and Canon’s MPE-65 variable magnification lens, among others. But for the sake of this discussion I am going to define Exotic Optics to exclude these consumer-type lenses. The lenses I want to talk about are in a subgroup of optics that are relatively rare, typically very expensive, not designed or marketed for use on standard camera equipment, and were developed with a very specific use-case in mind. The one thing that all these lenses have in common is that they are highly sought after by macro photographers because of their extraordinary performance. These lenses are usually of a fixed focal length and typically, though not always, have a fixed magnification ratio. Many are designed to be used wide open, and perform best with a wide aperture. None of them come with a standard camera mount and some require complicated special adapter setups to use with a consumer camera.


Most of the lenses I will be talking about are “industrial lenses”, designed for use in a variety of industrial applications, from making prints in the motion picture industry, to scanning silicon wafers for quality control in computer chip fabrication. They are used in machine vision applications where the highest possible clarity and resolution are required. Because they are not made for consumer applications they frequently lack specialized coatings on the glass elements, and often have no external controls or markings. They are possibly the only lenses that are more intimidating for mere mortals to use than microscope objectives.




I must make a confession here… While I have made it my business to learn all I can about these rare and expensive lenses, I do not own any of them. The lenses I am going to talk about are on my wish list list and are even listed in the order that they appear on that list. Some of these lenses are not absurdly costly, but the less expensive exotics also seem to be the hardest ones to find on the used market. With almost no exception, these lenses must be sourced on the used market, or occasionally through an industrial surplus outlet. Virtually never would we find these lenses in a consumer retail outlet, and many of them have been out of production for decades. The selection of lenses I am going to talk about are all lenses that I have studied in detail and many of them have been carefully evaluated and written about on specialized websites like Closeuphotography.com (Robert O’tool), Photomacrography.net (Rik Littlefield), and Coin Imaging (various), and I know many individuals who own one or more of these Exotic Optics. For example, the cover of Tuesday’s livestream shows a PN150 2.8 Printing Nikkor belonging to movie industry-insider, Mike Kanfer.

The lenses that I am going to focus on are listed below:

1) Printing Nikkor PN150 f/2.8

2) Printing Nikkor PN105 f/2.8

3) Printing Nikkor PN95 f/2.8

4) Mejiro Genossen FLO530 f/4.0 110mm

5) Etendue Mejiro OTH100 90mm f/5.6

6) Schneider Kreuznach Macro Varon CAS 85 f/4.5

7) Rodenstock APO-Rodagon-D 75mm f/4.5

8) Leica Z-Macro 100mm f/4

9) Zeiss -S-Planar 60mm f/4

10) Kowa LM50HC 50mm f/2.0

11) Computar F-mount 100mm f/2.8

You will notice that I have not included any of the excellent microscope objectives that could easily qualify for a spot on this list. That is mostly because we have talked about these lenses often and most of them are used for significantly higher magnification applications than these lenses. The optics I will discuss on Tuesday cover a range of magnifications from 1:4 up to 4X, though most are at or near 1:1. We will talk about the relative merits of each lens, why you might want one, and how much you can expect to pay, should you even be able to find one!

On Thursday we will continue our discussion of lenses by looking at the other end of the macro spectrum - affordable macro lenses. This will include both new and older macro lenses that can be bought new or on the used market at reasonable prices. Some of these lenses will surprise you, especially given the prices. We will stick to actual macro lenses, mostly from well known companies. Here is the link to the livestream…https://youtube.com/live/r8LuzT4lpRQ?feature=share

There was a problem downloading the recorded Episode 7, which is why the video has not yet been posted - I am working on a resolution and hope to have it up soon



On Thursday I talked about good, affordable macro lenses from many different companies - there was a lot of information to cover but here are links to every one of the lenses I talked about:

Key Characteristics to Look for

  1. Focal Length: A range between 60mm and 100mm is ideal for versatility in macro photography. The longer the focal length, the more distance you have from the subject.

  2. Magnification Ratio: All these lenses offer at least 1:1 magnification, crucial for true macro work.

  3. Autofocus vs. Manual: Many affordable lenses are manual, but autofocus can be a bonus if speed is important.

  4. Image Stabilization: Not all lenses have it, but it's a valuable feature for handheld macro photography.

  5. Build Quality: These lenses are known for their sturdy construction, especially those from third-party manufacturers like Tokina and Tamron.

Here are the lenses - note that the links are affiliate links, meaning I may make a small fee from Amazon if you buy one of these using the links below:
