"David Nebenzahl" wrote in message .com... On 10/1/2010 6:35 AM Cheesehead spake thus: I've been re-acquiring glass, in small quantities, to jump back in after my short hiatus from shooting. What I found myself doing was being more picky. Early on I tested out various lenses and found some good and some not so good, at least for me. For 4x5 I have 2 lenses: 135/4.5 Ysarex and 210/5.6 Caltar HR. Instead of the Ysarex (about which I admittedly don't know much), have you ever considered instead using the good old reliable Kodak Ektar 127mm? Got one with my Crown Graphic and have gotten excellent results with it. You could pick up a good specimen from a certain little online auction site for not very much. The Rodenstock Ysarex is a decent lens of the Tessar type. These were offered as standard equipment on Linhof cameras and on the late Speed Graphic cameras. They are perfectly respectable lenses. The Ektar series are quite remarkable lenses, very well corrected for color since Kodak was using them to sell color film. Kodak Enlarging Ektars are also excellent lenses. The f/4.5 and f/4.7 (the funny stop is because of the shutter size) are Tessar types but the f/3.5/3.7 for the Medalist camera and for small press cameras, is a variation of the Heliar. I no longer remember who buit the Caltar lenses for Calumet but they are Plasmat types similar to the Rodenstock Sironar and Schneider Symmar. -- -- Richard Knoppow Los Angeles, CA, USA |

AFAIK it was a trade name used to market equipment in the US that may have been made by any of several manufacturers. I think late Caltar lenses were made by Rodenstock, some earlier ones were made by Ilex, there may have been others. Ilex was capable of making good lenses but mostly made OEM lenses for small camera manufacturers and, of course, shutters. -- -- Richard Knoppow Los Angeles, CA, USA |

I have a couple that are my favorites, single coated Tessar type I believe, in Ilex shutters. Donn |

The name Topcon is derived from "Tokyo Kogaku", which translates to "Tokyo Optical (company)", just as Nikon (and Nikkor) is derived from "Nippon Kogaku" - "Japanese Optical (company)", and Ricoh is derived from "Riken Kogaku". The last one requires a little bit of explanation. The name "Riken" is another of those contractions which the Japanese are so fond of - it is short for "Rikagaku Kenkyosho", which means "The Laboratory of Physical and Chemical Research", a state-owned research laboratory from which Ricoh was spun out. As it happens, I spent two years in the mid-nineties working as a post-doc at Riken, in the optical engineering laboratory - which was "hikari kogaku" in Japanese. However, in this case, the word kogaku means "engineering", while "hikari" means light. Japanese has a great number of homonyms - words which are pronounced the same, but with different meanings. One of these words is "kogaku", which in some contexts means "optical", and in other contexts means "engineering" - the difference is clear in written communications where different Chinese characters are used. Apparently quite a few people did a double take when the phone was answered with "hikari kogaku". To get back on topic. One of my colleagues at Riken had a brother who worked at Topcon, and I was informed that the company was still very much in business, but concentrating on optical instrumentation rather than photographic equipment. Topcon was one of the main players in the 35mm SLR market in the 60's and early 70's, being one of the main competitors to the Nikon F with their "Super D". They have a claim to having been the first company to offer TTL (through-the-lens) metering, with the other contender being the Pentax Spotmatic. As far as I understand it, Pentax were the first to show a prototype, but Topcon was the first to actually bring it to market. Topcon withdrew from the photographic market around 1980. - Helge Nareid Norseman in Aberdeen, Scotland -- - Helge Nareid Nordmann i utlendighet, Aberdeen, Scotland For e-mail, please refer to my website.

It was fun to read all that, especially since I started out in photography around 1960 when all those great 35mm cameras were in production. You brought back fond memories. My first SLR was a Pentax H1a. Since it didn't have a built-in meter as did the Spotmatic, I used a $10 hand held selenium meter from Sekonic. That meter was the one I first used when I started shooting with 4x5 in 1989. I may still have it. |
