Hey guys,
I'd for some reason lost track of this thread (the forum wasn't sending me notification Emails?) and hadn't realized there were more replies. Sorry. Found the CPP2 service manual and...
Wow, thank you very much! Another very interesting reading. Although it doesn't mention a Holmes, Booth, and Hayden, the drawing of the Willard Lens camera on a telescope is exactly what I want to...
Super cool!!! Thanks; this is very interesting.
It is almost certain that this lens belonged to Barnard, or at least he tinkered with it, since it came from Yerkes Observatory, along with many of...
It's about 5, maybe 6 inches. It's enormous :) Yes, I'm assuming the F-stop to be around F4.
Can anyone give me any info on this giant lens.
The focal plane is around 24” from the flange. It may have belonged to EE Barnard who was a famous astronomer.
Truly any info appreciated....
Ever wanted an 8x10 film holder with ANR glass but thought that Negative Supply's $1700 solution was a tad outside of your budget?
Introducing a 3D printed 8x10 film holder you can make for about...
Yes, so I'm more than willing to take apart the pump; I was hoping for a servicing manual or something to guide me through the process. I couldn't see an obvious way to take it apart.
Or.... is it...
LOL, sorry I'd forgotten to update my info; I know CatLabs well, but unfortunately I have since moved out of Boston and am now in Albuquerque, New Mexico. Thanks :D
Hi all,
It's been a while since I've last posted here. Hope y'all been well.
Recently my Jobo CPP2 started acting up. The motor was getting sticky, struggling on reverse rotation. This I was...
As the creator, I can confirm that orders for this trickles in every now and again :) Thanks for the purchase, pathpounder!
Yeah, sorry, I only had several that I made, and do not have any more stock. The original idea was always that anyone who wants one can purchase the substrate from Shapeways, and an 82-77 step-down...
It's pressure as well as a notches that keep the assembly in place.
You slide down the holder, which has three slits where the three metal protrusions are on the inner circumference of the...
Wonderful idea :D Thanks!
[MOVED FROM CLASSIFIEDS]
So I got an Agfa Ansco Universal that was on Ebay. Has a couple holes in the bellows that needs taping but looks fine otherwise; and today I finally fashioned the lens...
Yeah, that is what I thought a Cooke looked like. My lens is arranged like the diagram I pasted. Convex/Concave element in front, then diaphragm, then )( then () . --- (( | )( () --->
With the Cooke design, though, doesn't the diaphragm come between the second and last lens? Also, I always thought Cooke triplets have two convex/convex and one concave/concave in the middle. The...
Well I received the lens. For sure, no engraving anywhere to be seen. The parts screw off easily and I see that there are indeed only three lenses in three groups. The configuration and placement...
Well, I've seen some beautiful images from the 18" Radar, so if it's that, I won't complain :D
Ah, Jason, howdy! I've watched that video of yours many times in the past :D I was very close to start working on a modified Speed Graphic shutter for barrel lenses (even have a beater SG lying...
Of course :) But the lens in question has no name engraved on it, period, so by that logic the lens is equal to no other lens on the planet, as pretty much all lenses have some engraving somewhere. ...
I won the bid :) Hoping it's a Sigmar/Varium relative :) I'll report on the actual FL, aperture, and optical design once I receive it.
Damn, couple of those Veritos went for really nice prices...
Love this thread! I need to fashion an adapter to attach my Graflex 8x10 FP shutter to my V8. I think I have the dimensions down, but really basic questions: where would I go in the US to buy the...
I will, though the only one I see on the 'bay now is $3000 :(
Really, would've snatched that 16" right away if I were around...
So I've been looking for a B&L Sigmar for years, and then I go to Belize for 6 weeks for research, only to come back to find that not one but TWO Sigmars came and went on the 'Bay during that time. ...
Looks very nice... I've been thinking about the Chamonix 8x10, but it looks like Svedovsky 8x10 would be more than good enough for me. I'd like a 5x7 reducing back, though.
If it is a true Linhof Select version, you probably will be able to sell it in the upper $1,000, if not lower $2,000 range on Ebay, where the prices for the lens has been slowly inflating over the...
Definitely get on the "Dancing With Speeds" group on Facebook.
I believe almost all 7in F2.5 AEs were made for the K-24 cameras. I pulled my current main model from a mint K-24. The latest SG is...
Yeah, 72XL and recess the lens by 3mm somehow?
The specs for Nikkor SW 75 @ 200mm seems to be at F16 so you might actually get a bit bigger stopped down further.
Is has the large round plate ;)
Thanks buddy! Was actually thinking the same thing.
I just got the Deardorff today and I see that the outer frame of the reducing back needs to be about 1/8in larger on each side; the main (for...
DOH LOL. Deardorff. Deardorff. I got my spellchecker to learn that spelling :) Making it 3/8 sounds like a really nice & stable solution. I love all these suggestions. Thanks guys. Deardorff.
I will ask Manfrotto :) It would be nice to have an "official" solution.
WOW, this is some cool stuff, never knew about these markings!! Thanks for the info!
Actually, I'm already thinking this would be the case; but one thing at a time, I'm already bleeding heavily from the purchases I've made recently :D I'd need to buy a sturdier tripod, too. 2014 :)
Sweet, exactly what I wanted to hear :D Off to the HW Store tomorrow :D Thanks!
Hi, I just got my first Deardorf 8x10 (woohoo) and immediately noticed that the screw hole on the base plate, which has a normal 1/4in female screw, is recessed too far and none of my tripod quick...
Of course... lol I guess the question really should have been like "has anyone done similar (or vice versa), and can tell me how difficult it would be?"
The Deardorf should be arriving later this...
