    Re: 7x11 Camera Build

    Hi Michael,

    Here's another question, if you don't mind.

    The base is made of 1/4"-thick craft wood glued edgewise. How do you ensure that it stays flat during the gluing operation?

    Re: 7x11 Camera Build

    Michael,

    Thanks for linking to this in your recent 5x8 build posting. I don't know how I missed it the first time around. Now that I've read through all of it I have some questions.

  3. Re: Just bought a Fujinon 135/5.6 W ( first type )

    It seems to me that a quarter of a second (250ms) is rather long for an M-sync delay. I always thought flash bulbs reached their peak output in 15-25ms. But unless you’re using flashbulbs this won’t...

    It might help to also consider what your plans are and how long you’ll be staying. LF gear may be fine if you’re going purely for photography and traveling alone or with a few others with similar...

  7. Re: Dagor Type G Claron 210mm f9 Filter Size ?

  9. Actual weight of 105mm Fujinon-SW vs. 105mm Fujinon-NSW?

    To be sure, neither of these is a featherweight.

    My 105mm NSW (the newer multicoated incarnation, Copal shutter, 77mm filters) weighs 605 grams with retaining ring and caps, 576 grams without...

    Re: Formula for Citric Acid Stop Bath?

    And household vinegar is 3-5% as I recall, so diluting 1:1 with water as Michael R suggests is fine.

    Personally I use food-grade citric acid, 15 grams per liter. No smell. Capacity is somewhere...
  13. Re: Using Rosco sheets in place of Wratten gel filters?

    Thanks guys, this is encouraging. I’ve added a sheet of R10 to my B+H shopping cart, that looks to be very close to a Wratten 8 and will test it against a glass filter.
  14. Using Rosco sheets in place of Wratten gel filters?

    Does anyone use Rosco filters in place of Kodak Wratten filters? The larger size, like 5x5 and 6x6 inch, Wrattens are hard to find in good condition and the few NOS ones that are available on eBay...

    Re: Question: When is 112mm not 112mm?

    No, and no. The outside diameter of the CF is almost precisely 112mm. It is physically impossible for something with 112mm threads to fit.

    Question: When is 112mm not 112mm?

    Answer: When Schneider's published literature says the accessory thread of the Center Filter IVb is 112mm x 1.5mm.

    Explanation: Two B+W 112mm filters I recently acquired measure 111.9mm across the...

    There are two versions of the 400mm Fujinon-T. The earlier one is single-coated, has a 240mm image circle, and weighs about 800 grams; the later version is multi-coated, has a 220mm image circle,...

    True, but...

    The original Apo-Sironar, which ultimately became the Apo-Sironar-W, was offered only in 150mm, 210mm, and 300mm focal lengths. So if you have a 135mm lens it can't be an 80°...
