  1. Re: Thoughts About Linhof 4x5 Technikardan 45s ?

    Larry, you may be able to use the 72mm with regular bellows, not sure about it, but surely without rise or fall, since the bellows will be completely compressed. As for 720mm, the Nikkor T ED is a...

    Re: kodak Tmax RS developer formula

    TMax RS keeps a long time in my experience if it is kept in full bottles. I had the big double bottle version some years ago when I could get a really good deal on it. I refilled it into smaller...
  3. Re: Thoughts About Linhof 4x5 Technikardan 45s ?

    Oren, fully stretched out as shown the distance between the film plane and the front of the front standard is about 195mm, about 205 mm to the center of the shutter. Not that one should do that,...
  4. Re: Thoughts About Linhof 4x5 Technikardan 45s ?

    From memory, the 150mm stretches it out, even though it is still physically possible at infinity. 120mm is no problem, and I assume
    135mm would work, unless you wanT to do closeups. But I’d have to...
  5. Re: Thoughts About Linhof 4x5 Technikardan 45s ?

    True. Alternatively, have the WA bellows on the camera, which is made from cloth. That is what I have been doing a lot.
  6. Re: Thoughts About Linhof 4x5 Technikardan 45s ?

    I’ve used a TK45 since 1991, and a TK45s later which is still my main camera. It is very versatile and can handle pretty much anything between a 47mm WA and a 720mm telephoto while still being close...
  7. Re: How to decide for a set of three lenses for a Linhof Technika IV

    I agree with Huub and others here that a series using a fixed percentage increase, i.e. a factor, can be helpful. What that factor should be depends on personal taste, which focal lengths the camera...
  8. Re: Schneider Hi End Back and Schneider Vacuum Backs

    And the final stage, the film pressed to the ground glass.
  9. Re: Schneider Hi End Back and Schneider Vacuum Backs

    Some more pics: film holder with one internal clamping frame removed; clamping frame with film; frame and film holder in the loading jig; and the holder inserted into the back.
  10. Re: Schneider Hi End Back and Schneider Vacuum Backs

    Here are some images of the system, more to follow, showing the back with ground glass, rubber bulb, and detached cover plate; the back with cover plate installed; the film loading/ unloading jig;...
  11. Re: Schneider Hi End Back and Schneider Vacuum Backs

    The - at least theoretical - advantage of the Schneider vacuum holder vs. others was that it eliminated any variation and tolerances in ground glass position vs. film position, since the film was...
  12. Re: Schneider Hi End Back and Schneider Vacuum Backs

    That is the back, replacing the original ground glass frame on the camera using the Graflok adapter. It does have the blackout plate - that is the part with the two blue knobs. Suction/vacuum is...
  13. Re: Schneider Hi End Back and Schneider Vacuum Backs

    Yes, it is the same thing. I bought one used about 14 years ago and have used it occasionally. I'll probably use it more when my stash of Readyload envelopes is gone (soon). When I bought it used...

    Re: 210mm f/5.6 - Rodenstock or Nikkor?

    I used the 210mm G-Claron for a while in the 1990’s for bulk and weight reasons. I was never 100% happy with it on 4x5, compared to an APO-Sironar S 210 mm, and later switched to a 210mm f/6.1 Xenar,...
  15. Re: What size paper do you print the most? What's the biggest print you've made?

    The main size is 11x14”; I’d prefer 12x16” if it were easier to get in the US. Some16x20”, some 8x10”, and 20x24” occasionally.
  16. Re: Performance Between Apo Symmar and Apo Symmar-L?

    It is initially an outright ban - another example is lead-free solder. I think you can apply for exceptions if there are no real alternatives (e.g. lead car batteries) and a near 100% recycling rate...
  17. Re: Performance Between Apo Symmar and Apo Symmar-L?

    Sal is correct, it was the phasing out of lead compounds (here: oxide) as part of the RoHS (Reduction of Hazardous Substances) regulations of the EU, that triggered the Apo-Symmar redesign....
  18. Re: When did decent wide angles show up? [lens history question]

    Dan, Pantogonal. No bridges were involved in the naming of this lens 😏.
  19. Re: When did decent wide angles show up? [lens history question]

    Actually, those designs, as well as any other in that family, are very similar. The basic design principle is that you have a group with negative power at each end of the lens, surrounding one group...
  20. Re: When did decent wide angles show up? [lens history question]

    What Dan said. Also note, the first Biogon type was only made in the 35mm focal length for Zeiss’ Contax rangefinder cameras. This design was never used for anything LF or even MF related.
  21. Re: What lens to get for most shallow depth of field on 4x5?

    In the 100-140mm range, you likely won’t find 4x5” lenses with openings larger than F/3.5. Essentially, 135mm f/3.5 is the only combination I can think of, either as Schneider Xenotar, Zeiss Planar,...
  22. Re: What lens to get for most shallow depth of field on 4x5?

    Without any other considerations, such as shutter compatibility, age, coated or uncoated, focal length, etc., the following lenses come to mind:
    Aero-Ektar 7” f/2.5
    Schneider-Kreuznach Xenotar...

  24. Re: Which lens is this E58 4x Rodenstock center filter for?

    Dan, that recommendation is most likely for their modern WA lenses with approx. cos^3 falloff characteristics, whereas the Geronar WA will have cos^4 characteristics. The smaller front opening of...
  25. Re: Which lens is this E58 4x Rodenstock center filter for?

    The Geronar-WA 90mm had a 58mm filter size. Since it is a double Gauss WA, it would have more falloff than a more modern 90mm WA design, which could explain the 4x center filter, although I do not...

    Re: Linhof Kardan question

    Daniel is right that a Kardan means gimbal - however, the connection to drive shafts (named “Kardanwelle” in German) comes from the fact that a drive shaft usually has one or more universal joints,...

  29. Re: Model name of your large format enlarger please

    Its a piece of foam tubing. The Zone VI/Calumet LED head has a cooling fan in it, with the air blowing out on the left. Attaching the foam tubing to that opening reduces the fan noise to near zero

    At 3.5 feet from object to lens, your magnification was about 1:6. As Pere and Bob mentioned, it is not a macro lens, although 1:6 stopped down should still be reasonable. Try again with something at...
