    Extremely Long Apo Ronars?

    Hi All,
    I have just picked up a 600mm F9 Rodenstock Apo Ronar, the classic process lens (not the newer variety, the original one). I know I have seen the 800mm, I think they made a 1000mm, and a 1700mm? What focal lengths in really long Apo Ronars are available? Does anybody have a link to any original Rodenstock literature?
    Thanks in advance!
    -Dan

    Re: Extremely Long Apo Ronars?

    I have a 1985 Rodenstock lens brochure that has quite a bit of info on the Apo-Ronars.
    I believe it shows the complete Rodenstock line of lenses for 1985.

    The brochure lists Apo-Ronar lenses at 150, 240, 300, 360, 420, 480, 600, 1000, & 1200mm. This brochure does not show an 800. It shows image circles, but does not include MTF information or resolution. For example, it shows an image circle of 496mm for the 600mm lens. I regularly use this lens on my 8x20, but I have never run out of coverage. I do not see any softness in the corners so I've concluded that because I'm contact printing everything, there is more useful image circle than 496mm. For the Apo-Ronars, it shows MTF data only for the 240mm lens.

    I've converted the brochure to PDF, but I don't have a website so that you could download it. If you are interested in a copy, please PM me with your email address and I can email it to you. It is 6.2 MB in size.

    John

    Bob - I have a 420mm f9 Apo Ronar - where does it fit into your schedule of lenses and what is the maximum format can it be used with.

    Found a brochure!

    42° coverage, 67mm filter, 75mm slip-on size, 70mm rear diameter, 404.5 flange focal length, 68mm long without protective glass, 71.5mm with protective glass, 90mm x 1 mounting thread. The preceeding is for the lens in NF mount. Not in shutter. At f22 @1:1 it covered 16 x 20"(40x50cm). The 420mm was available as an Apo Ronar and as an Apo Ronar CL. The non CL had a 72mm x 1 mounting thread. Both had an effective focal length of 421.3mm. On the CL smallest aperture was f90. On the non CL it was f260. Rear mount on CL was 88.5mm and the flange focal length on the CL was 401mm, length was 64mm and the maximum lens diameter was 105mm.

    So which one do you have?

    This is good information I don't see in the old brochures I have. The 420mm seems to be omitted for some reason. I have one in good condition and am looking for another one, to go on my 5x7 twin lens Sinar Norma

    Beauty Lighting 790mm F14 Apo Ronar 5x7 Norma by Nokton48, on Flickr

    Setting up to use the big 790mm F14 Apo Ronar on the 5x7 Sinar Norma. 47 inches of bellows extension equals 1 1/2 stop bellows factor. Will try some horizontals, using HRU XRay and also Ilford Ortho Commercial.

    I placed a large order for 13x18cm B&W (buying a variety) from PhotoImpex in Germany. Should be shipping soon as Ilford delivers to them 13x18 Delta 100. Ordered FP4+, Fomapan 200, Fomapan 100, Adox CHS 100 II, and Delta 100 all in 13x18 format. I have plenty of 13x18cm Sinar Norma holders

    Daniel I hope you didn't get the one Calumet was selling on ebay. I purchased that lens a month ago and returned it because of mechanical issues, a big dent and the front and inner element were loose and rattling in the mount. Also it wasn't coated. Calumet is generally very good but they really slipped up on that one.

    I picked up another from a forum member and love it although I'm about to sell it. I just picked up a minty Fujinon C 600mm.

    Don, how can a modern lens not be coated?
