Um, er, ah, the normal focal length for 2.25"x3.25" (6x9 is a poor metric approximation) is 100 mm. If you're not going to shoot 4x5 or use large movements why not get a 100 or 105 mm f/5.6 plasmat...

The most likely is that your previous purchases, like mine, came by mail. Couriers such as FedEx, UPS, DHL ... charge customs brokerage fees. I see this as dishonest and insist that my goods be...
Thanks for the reply.
My, you must be rich. Asking prices for long Super Sixes are well into 5 digits (USD). Have you considered getting an 8"/2.9 Pentac or a 7"/2.5 Aero Ektar? They're much...
Don't be so coy. Tell us which 8" Dallmeyer lens you have. Name, focal length and aperture. If it is a Super Six, it might not fit a Compact 5x7's board. Unfortunately my references don't give...
No change needed.
Re post #2 above, G-Clarons, Repro-Clarons, Comparons and Componons (older jes' plain and newer S-) have cells that are direct fits in various sizes of Compur/Prontor/Copal...
Mark, I have 203/7.7 Kodak Anastigmat. It has the same prescription as the 203/7.7 Ektar. Mine is in barrel. I have other 200 +/- mm lenses so haven't tried to find a shutter that's right for the...
If the lens is coated there will be a C with a W inside it on the trim ring. It should be coated. Large scratches can be filled with, e.g., India Ink.
To find out whether the scratches will be a...

Um, er, ah, if I understand these things correctly the lens board goes between the rear of the shutter and the retaining ring, not behind the ring. The ring's flange should butt on the board.
Mark, I'm sure that, given your profession, you know that every lens has three focal lengths.
There's the engraved/marketing focal length. There's the design focal length, i.e., of a lens made...
It is a triplet whose maker - Taylor, Taylor & Hobson - thought it could be used on formats up to 3.25" square.

Not to be a complete idiot, but is it possible to mount a lens with a fat rear cell on y'r 5x7 Gandolfi by removing the rear cell from the shutter, attaching board with shutter to the front standard...
Wise. I once bought a late WW-II vintage coated Aviar that had haze I couldn't clean off. Close examination found that the front glass had many many tiny pits.
Your lens is in a Kodak branded Ilex #4 shutter.
The cells should unscrew from the shutter. Don't try to take the cells apart.
What is this "lens retainer" of which you speak? What I understand as the retaining ring, which clamps the shutter...
Hmm. Please don't get cute when posting links. Yours doesn't work. This https://www.pacificrimcamera.com/rl/00268/00268.pdf does.
Please read more carefully. The left-most column of the table...
Check the rear threads. #1 shutters are asymmetric, M40x0.75 front threads and M36x0.75 rear. In other sizes front and rear threadings are the same.
False.
OP, you've rediscovered the center filters made for Bausch & Lomb Metrogon lenses, wide angle lenses for aerial photography.
Is there a T-mount SLR?
Per P-H Pont's chronology, 1938.
Thanks for explaining what you're trying to accomplish. Using a small format lens on a larger format isn't a good approach to getting "soft focus." Nearly all small format taking lenses are...
pigpen, in post #3 above I asked you what you wanted to accomplish by mounting a "35mm lens" on a larger format camera. Please answer my question.
Your post #11 above on why you have a Crown...
Oy? Which format do you intend to use a "35mm lens" on? What do you hope to accomplish?
I ask because, although lenses for 35 mm cameras can be used on larger formats for macro work, as John...
Thanks for the correction.
I've never seen anything solid to support the assertion but people have asserted that brand X offers (a) consistent color rendition across the line and (b) that color rendition is (pick one) warmer...
Absolutely not. In post #14 above, the poster wrote "This confirms my doubt that it would be a 6x9." I think "it" is the 105/3.5 Tessar that's the subject of this discussion.
The normal focal...
Huh? For which format is 105 mm the normal focal length? And 150 mm?
Why two flanges? Either will do. And that answers the question. If you want to mount the lens on a lens board, have the board bored to accept the flange you want to use, drilled and tapped for the...
You just confused me. You may be confused too. WHERE are these 79.375 threads located? The brochure shows the lens' rear tube -- this is the lens' rear cell -- as smooth. The front of that tube...
Hmm. The lens' rear barrel will stick out behind the shutter if it is in shutter. If you attach an M90x1 flange to the board the rear barrel will stick out behind it. You have the lens. Measure...
It is a normal lens for 2x3 (6x9 in metric). Absolutely not a w/a lens for 4x5.
confusion. Also confusing, but that's a different idea.
Hmm. Perhaps I don't understand how sliding box cameras work. As I understand them, the rear standard on the larger box is fixed. The front standard with lens, on the smaller inner box, moves to...
Well, the guy said he was shooting digital 8x10. He was using a tiny digicam to shot an image on an 8x10 ground glass. My monitor is larger than 8x10. Following that logic, if I used a tiny...
If you're asking about the lenses' depth-of-field scales, the diameter in the circle of confusion used in calculating the scales is an unpublished arbitrary number, usually larger than a picky...
Do they cover 4x5?
Completely normal.
Oh! Not that dishonest gimmick again.
If you must do it, consider a sliding box camera.
There are several ways to use barrel lenses. For long exposures, anything opaque in front of the lens will do. Hats are often suggested. Remove, count time, replace.
For short exposures,...
