Happy SUNday! – discovering the Contax RTS ‘Sci-Med’

January 21, 2024January 21, 2024Chris and Carol 2 Comments

Scientific/Medical ‘Sci-Med’ camera with a Real Time Winder both are from around 1977 or early 1978. No official documentation exists on this variant of the Contax-Yashica RTS (first model) released in 1975. It’s been referred to as the RTS ‘Fundus,’ but again, there needs to be a mention of why it was produced and for what purpose beyond the Sci-Med community to be able to accept that designation, in my opinion. Slight enhancements include a small raised collar around the sensitive magnetic shutter release button and a shutter speed lock button on the right side of the camera’s top plate (as viewed from the front). The shutter speed dial locks in the 1/60 position (electronic flash sync speed), and the button needs to be depressed to select another speed. The Real Time Winder was mated with this camera as they shared the curious ‘Registered Number U.S.A.’ sticker. Many unknowns exist about this limited production camera, and much misinformation is floating around. I hope to uncover some truths or, at the very least, present only factual info. If you have documentation concerning this Scientific/Medical version, please share it with me – advertisements, brochures, or mentions in the photographic press back in the day.

Most RTS cameras have degraded or peeled leatherette coverings as the adhesives and the slightly softer leather haven’t held up over the decades. This one has, for the most part. The RTS line (RTS, RTS II Quartz, and RTS III) all use lenses with the Contax/Yashica (C/Y) mount.

The Real Time Winder can shoot up to 2 frames per second (2 fps). Higher-speed motor drives and winders with speeds up to 5 fps were also available.

The JCII ‘Passed’ sticker is in a different position from where these stickers were usually placed on the RTS, which would be on the left side of the prism. I guess it was put here on the Sci-Med version because the ‘Registered’ sticker was placed on the prism (by the factory or the distributor?).

The baseplate is marked ‘Scientific / Medical’; otherwise, it’s not different from a standard RTS.

The registration numbers are different, but the winder and the camera body were together as a set when I purchased them.

Early magazine advertisement. Here, it incorrectly indicates that the Real Time Winder is capable of 2 1/2 fps. The manual has it at 2 fps.

Beautifully designed and highly functional.

The Contax-Yashica RTS, Real Time System, was jointly developed by Yashica and Carl Zeiss, with the design originating from Porsche. The camera features fully automatic through-the-lens electronic exposure control; select the proper film speed (ASA, ISO) and the desired aperture (f-stop), and the camera selects the appropriate shutter speed. It’s also a fully manual camera, with the user setting the shutter and aperture values. It was a camera I was initially interested in when I was looking to replace my first SLR, the Yashica TL Electro-X, in 1978 when I was stationed in the Navy in Japan. If I remember correctly, the Navy Exchange stores didn’t have a large selection of Contax cameras, so my choice quickly became the Canon F-1 over the Nikon F-2.

Here is my first Contax RTS, which isn’t the Sci-Med version.

I chose the Yashica ML 50mm f1.7 lens over the more expensive Zeiss T-Star (T*) lens.

Contax RTS Serial Number(s)

January 18, 2024January 18, 2024Chris and Carol 3 Comments

In the Contax RTS instruction booklet, the baseplate pictured either has a “real” serial number or one “made up” by the marketing department. RTS models out in the wild don’t have a serial number that is easy to decode (date manufactured), but this one does, at least if you know how to read Yashica serial numbers. I interpret this SN as February 1975 (502), and its number is 166.

The original instruction booklet (dated 06/76) has an 8-digit SN.

My RTS baseplate has serial number 087024, which looks nothing like the serial number in the instructions.

Here is a baseplate from an RTS-Fundus Scientific / Medical camera. I see 091238. I don’t see a date code in there – do you?

Anyway, this is just a quick post to gather my thoughts. Do you own a Contax RTS first model? I’d like to see more serial numbers as a pattern may appear. Thanks for stopping by, Chris

Brothers from different mothers – Contax RTS and Fujifilm X-T2

January 15, 2024January 15, 2024Chris and Carol 1 Comment

Brothers from different mothers – the classic Contax-Yashica RTS (original model) and the Fujifilm X-T2. I find the weight and feel to be the same, and many of the manual controls I use are right on top of the T2. That could be why I was attracted to the Fuji in the first place.
In the world of modern mirrorless digital cameras, the T2 just feels and acts like an old-school SLR.

The Fuji features a sharp Fujinon zoom lens, and the RTS has a fast and sharp f1.7 Yashica lens. I enjoy the aesthetics of both cameras, and I often shoot with the half-cases attached.

Fujifilm got it right when they designed their T2 (and similar models), drawing on the successful designs and functionality from the past.

A better view of the lenses. I chose the Yashica lens over the much more costly Planer lens because, let’s face it, Yashica made both (maybe from a Tomioka design in collaboration with Zeiss). The famous T* coatings may be missing on the Yashica, but I doubt it. The T* mainly was a marketing exercise. Full disclosure – I’d take the Zeiss Planer in a heartbeat if money were no object.

I enjoy using my Fuji; it is my go-to camera whenever I shoot with my classic lens collection or when I need to test a lens before listing it in my Etsy shop or on eBay. It’s fast and easy, and the APS-C sensor has a 1.5 crop factor that “boosts” the focal length of every lens I use. See yesterday’s gorgeous 450mm shot below from my 300mm Nikkor-H lens.

Big glass from 1970 – Nikkor H Auto 300mm

Today’s Lens Camera Combo

Nikkor-H Auto 300mm f4.5 Lens
Nippon Kogaku Japan – 1970
35mm Equivalent 450mm

35mm equivalent is a 450mm telephoto. Seen here as an out of the camera JPEG image. ISO 1600, 1/1900, f5.6.

I enjoyed my first outing with this massive lens on my T2 but without any type of image stabilization I had to bump the ISO and shoot at a high shutter speed to get the images in focus (no tripod).

The neighbor’s chimney top as seen from my studio at 450mm. It was a rather dull day with high cirrus cloudiness blocking any chance of brighter colors. Hopefully, the sun will shine brighter tomorrow so I can get out and about again.

Happy SUNday! – My most favorite Yashica set

January 7, 2024January 7, 2024Chris and Carol Leave a comment

Over the years, I have collected an incredible variety of cameras made by Yashica, from their earliest days (1953) to the last true Yashica models in the late 1980s to early 1990s. I’d have to say that this Yashica Pentamatic set (made in August 1960) is my most impressive find. It’s a one-owner set, and it is in like-new condition. It came with some unexpected goodies (pictured), too.

Hallmarks on early Japanese leather camera cases

January 6, 2024January 7, 2024Chris and Carol Leave a comment

1953
After 6 decades of use, this leather case for the Yashima Flex TLR camera stands strong. It is relatively rare to see a Yashima-branded item outside of Japan; this represents the first time Yashima used its name on a case.
I don’t believe Yashima-Yashica made their own leather cases. As a start-up company back in the early 1950s, Yashima and other camera manufacturers likely contracted outside companies to make their leather cases and branded goods so that they could focus on their core activities. Many of these early cases have distinct markings on the bottom, indicating the hallmark of the company that produced it.

From 1953, a beautiful example of a Yashima leather case.

An early example of a hallmark on the bottom of the case.

I have a few additional examples in my collection – time to dig them out and photograph them. Have you seen a Japanese leather case with what appears to be a hallmark? Please, share if you do. Thanks for stopping by, Chris

More about the E.P mark on Japanese-made cameras and lenses (1953-1977)

January 5, 2024January 5, 2024Chris and Carol 3 Comments

There is still plenty of conjecture about the exact meaning of the two letters that appear in a diamond design on Japanese-made photo gear made in the 1950s and 1960s and gradually disappearing in the mid to late 1970s. Some suggest that it meant “Exchange Purchase” since the mark often appeared on cameras sold in military exchanges throughout Japan during that period. The catch is that not all of the cameras sold in the exchange stores had that mark – probably only 30% or less, depending on the decade and store. Stereo equipment was also marked as was binoculars. Expensive jewelry and watches didn’t have the mark. So what gives, and exactly who ordered the symbols to be placed on, at times, random items within these few categories.

Here is a never-before-seen (by me) mark on the presentation box of a <E.P> marked Nikon S2 35mm rangefinder camera from the 1950s. The camera bears the mark, and so does the box. It’s too bad the box doesn’t have an affixed price sticker. It would have been interesting to see which exchange it sold in and for how much.

Look closely at the image of this Nikon box pictured below. In the upper right-hand corner is a price sticker. The sticker has quite a bit of good information, but it also leaves out some vital info. The “Japan Tax Exempt” and dollar amount printed on the sticker are such a tease. The camera was from the early 1970s, so it could have had the <E.P> mark, but not necessarily. From memory of my time living in Japan and shopping at the Navy Exchanges in Yokosuka and Yokohama, I don’t ever recall seeing a price sticker with “Tax Exempt” printed on it since everything sold in the exchange was tax-free and therefore tax exempt. If it wasn’t sold at the exchange and in fact sold at a duty-free or tax-free shop in Japan, why would it be priced in USD and not yen?

My 1955 Nicca 3-S with a <E.P> mark on the rewind knob (typical placement of the mark).

No record exists that explains precisely what the “E & P” stood for or why the program existed and, for that matter, who instituted and administrated the process. I believe the mark was primarily intended to deter the black market reselling of photo gear to Japanese civilians by military personnel since the cameras were tax-free in the military stores and were more than likely also priced lower than the same camera “out in town” in a Japanese camera shop. It’s likely “EP” stood for “Exempt Purchase” or “Exempt Product” and not “Exchange Purchase” for the reasons I stated in this post. Do you have additional information about the program? Do you fondly remember purchasing a great camera at the exchange, please share it.

Yashica TL-Super 1966

January 5, 2024January 5, 2024Chris and Carol Leave a comment

Yashica’s first through-the-lens (TTL) light metering single-lens reflex (SLR) camera. Two CdS resistors measure the average degree of light entering through the lens and directed to the focusing ground glass. The TL-Super started a bunch of great things at Yashica.

In addition, the TL-Super was the first Yashica SLR with a fixed accessory shoe (flash hot shoe) mounted to the top of the pentaprism (woohoo)!
