Leica Projector Lenses

Dust long having settled on the carcass of the industry, it seems in hindsight that Leica treated the production of domestic slide projectors more seriously than the Zeiss / Zett / Voigtlander combine. Leica’s catalogue of projector lenses represents the acme of the craft, matched by none for breadth and few for depth: for image quality, only Rollei and Braun’s finest lenses compare.

Leitz projectors date to at least 1933, when the catalogue shows four models, including a Standard projector (UKLON), onto which was fitted the four-element Elmar 50/3.5 (commonly marked 5cm) taking/enlarging lens. The UBELA and UDANO projectors had a film magazine and semi-automatic transport and was capable of deplying the stock Elmar 5cm, or 90/4, 105/6.3 and 135/4.5 variants, as well as the Hektor 73/1.9. Finally, UKABY was supplied with fixed 80mm or 120mm lenses.

By 1939, Leitz had a compact model in the range: initially called Gnom, but renamed in the 1940s to Parvo. These models had fixed Hektor 80/2.5 or 100/2.8 lenses. Parvo evolved into Parvo II and by the early 1950s, the Prado range.

Before singling out individual lenses for comment, we can draw from Delta’s archive the following summary:

The Colorplan Story

Leica’s Colorplan slide projector optics are, quite properly, the best-known and most highly regarded lenses of their kind. While other products may match their performance (Rollei’s AV-Apogons, Braun’s Ultralits and Schneider’s Xenotars are certainly in the running for ultimate honours), nothing matches the heritage of the Colorplan, originally designed by Walter Mandler in 1958/9. Given how well our 1960 test sample performed in 2022, it must have been a revolution – its complex design a shark among triplet minnows in the early Sixties.

They are also marked out by offering an unusually high level of performance at an affordable price. Leica made them well and sold a lot of them, for a long time – resulting in a potentially daunting number of variants – seemingly all 90mm and f2.5 – swilling around today’s marketplace, commonly divorced from the projectors that once housed them. If you’ve only ever heard of one projector lens, it’s probably a Colorplan. If you’ve only ever taken pictures with one projector lens, it’s probably a Colorplan. However not all Colorplans are the same – or even 90mm.

Its history is somewhat tarnished by reports of inferior build quality in the early phase of Portuguese production – from approximately 1980 to 1985. The factory in Vila Nova de Famalicão began to output optics for Leitz in 1975, but Colorplans of the 1975-1980 period all seem to be German-made. In 1981, Leitz debuted a ‘CF’, or Curved Field, variant of the Colorplan 90/2.5 that was produced in both Germany and Portugal during the early 1980s. Evidently production of Colorplans at this time was split between both facilities, and it’s unclear whether there are meaningful differences in build quality between the two factories, or whether the differences are by design. Marco Cavina’s article documents a series of cost- and weight-cutting measures undertaken by Leitz in the early 1980s to lower production costs to the point where most Leitz projectors could ship with a Colorplan lens: ‘Made in Portugal’ models are almost 60g lighter than the late 1970s Colorplans, and generally inferior in construction, which impacts on performance by making them more prone to internal reflections. The optical formula was unchaged. Given the global cachet of ‘Made in Germany’, it’s somewhat mystifying that Leica chose to advertise the provenance of the Portugeuse lenses so prominently – perhaps a rare triumph of honesty over (political) ‘optics’.

However, when Leitz restructured and rebranded in 1986, the German-made P-Series Colorplans, now marked Leica Colorplan-P (instead of Leitz Colorplan) were made using the same ‘cost-efficient’ parts as the Portugal models. In fact, subsequent production was split ‘silently’ between Solms and Vila Nova de Famalicão, and standards improved at the remote facility to the point where the distinction between German and Portuguese lenses became meaningless.

Purists still argue that peak Colorplan (mechanically, at least) was the original [V1] ‘Leitz Wetzlar’ production. Optically, though, the later six-element lenses were slightly superior. As taking lenses, both are fine: the early five-element models are actually sharper in the frame centre, but the late six-element version is better in the outer image circle.

Here we explain the when, what and where of Leica’s Colorplan 90/2.5 models – or Leitz Colorplan as they were known pre-1986 . . .

Lens Designation	Cat. #	Production	Elements	Notes
Leitz [Wetzlar] Colorplan [V1]	FEDUU	1958-1967	5 / 4	All-metal silver barrel. Marked ‘1:2.5/90mm’ Single-coated. Made in Germany.

Leitz [Wetzlar] Colorplan CF [V2]	37 015	1981-1986	6 / 4	As [37 005] but ‘Curved Field’. Marked ‘2.5/90mm’. Markings on inner fascia. Made in Germany. Multicoated.

Leica Colorplan-P CF	37 015	1986-1990	6 / 4	As above, but ‘Curved Field’.
Leica Colorplan-P2	37 512	1990-2006	6 / 4	Made in Portugal. Black plastic barrel. Revised optical formula. Leica-branded and multicoated.
Leica Colorplan-P2 CF	37 513	1990-2006	6 / 4	As [37 512] but ‘Curved Field’
Leica Colorplan-Pro	37 354	1998-2006	6 / 4	For Pradovit RT Series. Black metal barrel. Multicoated.

Although we have here differentiated eleven versions of the 90mm f2.5 Colorplan for the purpose of accurate dating and identification, not every difference is significant. There are three major variations to take note of:

1. The original single-coated, five-element [V1] produced from 1958-1967 (FEDUU)
2. The six-element [V2] (catalogue 37 005) and ‘Curved Field’ variant (catalogue 37 015), which together stretch from 1967-1990, gradually acquiring multicoating, dipping in build quality during upscaled Portugeuse production of the early 1980s, and including the original P-series Colorplan – and:
3. The final, and most desirable, post-1990 ‘P2’ revision (catalogue 37 512).

Leica Super-Colorplan Variants

The trio of Super-Colorplans are products of the Leica era, not arriving until 1993 and apparently simultaneously launched in P and P2 mounts – the former only fitted to the Pradovit P2002 and the latter initially provided as a factory option for the Pradovit P300, although it naturally became an option for all subsequent P2 series models.

A fitting apotheosis to the Colorplan story, the final Super-Colorplans were five-element designs like the original FEDUU variant. They were hugely more expensive than the six-element standard Colorplans of the Leica era, featuring aspheric glass and state-of-the-art multicoating. Super-Colorplan-P has quite a different barrel design: 84mm long vs Super-Colorplan-P2 at 94mm. P2 is also heavier, and has its rear element sitting almost flush with the rear of the barrel, and it has a deeper front hood. Super-Colorplan-P therefore has a longer focal-flange distance (measured from the end of the barrel) because its rear element is recessed by around 15mm. The two lenses have the same coating on the rear element, but different multicoating on the front element. Both were made in Portugal.

As taking lenses, Super-Colorplans offer performance similar to the Elmarit primes of their day, albeit with a fixed f2.5 aperture, and better optimised for long than short distance. Zone A sharpness is very high, matched only by elite 35mm projection lenses like the Rollei AV-Apogon. Bokeh is smooth and harmonious, though not quite as attractive as the six-element versions, in my opinion. However, colour reproduction is unmatched among optics of this type.
