updated links to vendors' LF lens info

Since I was doing some browsing of my own, I thought I'd provide updated links to manufacturers' and importers' "official" lens specifications, limited to manufacturers who are currently active in LF lenses. Perhaps after the message scrolls off one of the moderators can use the information to update the corresponding part of the "commercial links" section of the LF info site. I've selected English-language sites wherever possible.

Rodenstock:

Schneider:

(Schneider Apo-Helvetar for Alpa 12 cameras) http://www.alpa.ch/alpa/helvetar.htm

Fujinon:

(Current LF lenses) http://www.thalmann.com/largeformat/mar-1997.htm

On this page Kerry Thalmann has kindly provided scans of specification tables from a Fujinon lens brochure dated March 1997. For non-Japanese readers, these are easier to read than the tables on the Fujifilm site in Japan. I have reviewed the Japanese web site today and verified that Kerry's scanned tables are still up-to-date for the current product line.

Nikkor:

(Current LF lenses) http://www.europe-nikon.com/category...d=22&catId=149

This link leads to the Nikkor-W page; there are links to the other lens series on the left side of the page.

Caltar:

(Current LF and "digital" lenses) http://www.calumetphoto.com

No direct link - need to go to Calumet home page and enter "Caltar" into search engine in upper right corner, then click on individual product links. Caltar II-N lenses are Apo-Sironar-N, Geronar and Grandagon-N lenses made by Rodenstock. Caltar-D (digital) lenses are listed without specifications, but the focal lengths offered appear to match the Schneider Digitars.

Sinaron:

(Current LF and "digital" lenses) http://www.sinar.ch/down/sup/prka_objekt_e.pdf

Sinaron LF lenses are Apo-Sironar-N, Apo-Sironar-S, Apo-Grandagon, Grandagon-N, Apo-Ronar and Apo-Macro-Sironar lenses made by Rodenstock. By specifications, the Sinaron Digital lenses appear to be a mix of Rodenstock- and Schneider-sourced lenses.

Congo:

(Current LF lenses) http://www.cosmonet.org/congo/spec_e.htm

Osaka:

(Current LF lenses) http://www.bromwellmarketing.com/lenses.htm

Comparing specifications, Osaka lenses appear to be mostly Congo lenses, except for the 150 and 210 6-element lenses. The specifications for these two lenses appear to match those for the corresponding Wistar W lenses, a series offered by Wista only in Japan, and which I've never seen in the US.

Wisner:

(Convertible plasmat) http://www.wisner.com/Page14.html

(120 and 210 compact lenses offered with Flight 4x5 model; minimal info; also made by Congo?) http://www.wisner.com/flight.htm

Cooke:

(Links to pages for both XVa Triple Convertible and PS945 Portrait from home page - scroll down) http://www.cookeoptics.com/

I'd welcome any corrections or additions to this list.

Thank you. Good work.

Thanks Oren, I will update the "Resources" page http://www.largeformatphotography.info/resources.html
with your information.

A correction to the "Caltar" entry - Caltar II-N lenses are Apo-Sironar-Ns and Grandagon-Ns; Caltar II-E lenses are Geronars.
