Haha, I guess that's why they marked apertures down to 128 (as someone said before, not 90 like they were going to) AND it moves much farther down, looks like enough room to go to 256 actually.

Bernice,
Interesting point on the taking aperture and diffraction, but for some reason I'm thinking they might have foreseen that and worked it out one way or the other.
Goerz lenses are...
I might know that 'collector' - couple of my Dallmeyers went to such a gentleman a couple of months back, but the one I know uses them super rarely just to see I think.
The math does work out...
Yeah, but aren't the 20x24 cameras running still? Isn't there a kickstarter right now up with Impossible guys wanting to use that chemistry and revive 100-series peel-apart films? I mean Polaroid...
Interesting because the one I have for sure hasn't changed hands in 6 years. Tracy said he thinks there's 5 or less of them, I wonder if Polaroid still has their two or did they sell one...? The...
Oh, I see a actually already listed the Toyo setup - there was so much stuff there that even with all my previous selling experience I'm having a hard time keeping track...
Haha - well, I mean I did, but it kinda decided to follow...
Bernice - 1200mm were made in Tele design usually, those would cover say 11x14 nicely, maybe 16x20 at infinity. This thing has an...
Reviving a thread 8 years after last post.
Question - what would one do if one found this lens in mint condition?
Thank you Dan and everyone!
Let's see what this 20x24 Scovill Portrait Climax can do. With its 6ft bellows draw things should be pretty interesting.
Now, I kinda assume that reversing an LF lens would also make sense, right?
You guys are awesome - reversing a lens due to switching around the distances never occurred to me. Reversing something like my 180 should work too, right?
Then again I also have some Rolleiflex...
Hello and thanks for helping out.
I'd like to do an ultra-macro project (10:1 or more) and and pondering how to go about it. I have a few cameras with extensive bellows draw, so that's not a...
Fantastic info Anachromatic! Thanks so much! Very much looking forward to soon testing this lens too - fitting a spring back onto the swinging-style Century 11x14 and then it'll be ON!
OK, so I put my lens on a camera today. Indeed it is 20in FL (at infinity from aperture point) and so the f5 mark on that Studio shutter is correct.
One surprise to me was that moving the lenses...
Thanks for keeping the thread going guys!
Steven - great info in that book. So it reads to me as if the sliding part is not really meant to adjust focus imperfections of change focal length of...
Ok, so maybe there the section is 2.5in or so, but it extends a little longer - totally looking forward to seeing what it does.
Wow - I think the one in the eBay link above there is going to be either longer than 20in or 20in but faster than mine (assuming of course that my assumption that f5 marking on my shutter and 4in...
On the Busch I have that extension is like 3in at least. I'm gonna mess around with it once I get the studio set up and can actually play with the 11x14 Century that's been awaiting in the wings....
Oh, so THAT'S what lens my extra pinion is from. :)
The only other lens I've seen that does that is Zeiss Tele-Tubus. My guess id that angle cuts are more precise and also don't slip at all.
...
Also in the ads here you can see that that's not glass diameter that was 10in - that was focal length :D http://antiquecameras.net/1904buschlensads.html
A 10in glass f3.5 lens would be 35in long -...
Also bummer they apparently didn't put serial numbers on any of their lenses - I mean what gives?...
OMG Steven - you really think it's 10in GLASS Diameter? I think it's focal length.... I mean in a museum in Rathenow there's a 6in glass diameter lens and it's said to be either the only one ever...
Hi ALL!
I'd like to ask if anyone has any info (or knows of a place online where some is tucked away) on Emil Busch lenses. In particular I'm looking for info on larger than average Pezvals, but...
Update for anyone who cares - found a B&J 8x20 recently - complete with case, three holders, extension rail and the B&L Tessar they advertise in the catalog (on an Ilex 5 shutter). Along with it...
Update - Carrol at Flutot's got it humming! She's amazing!
Quick question to the knowledgeable ones. I read through this thread and see that someone mentioned that at first these Darlot lenses were made with a hemispheric design, but then switched to...
For those who care here are the test plates from it.
First one wide open and second one with an f9 or so Waterhouse stop I fashioned for it. It's not the sharpest lens I've ever seen, but if...
Thank you all for the input - it's really fascinating and helpful.
Garrett, the knurling by the flange is indeed straight, but on the retainers for the lens groups it's sideways.
I guess it is...
And here's the rear - the inner tube holding the glass comes out a lot smoother from the rear, so that's why I extracted it and not the front, both are made of identical thin metal, too thin to...
Nah, Jim, I mean the might have taken out rack and pinion and cut the slot, but I doubt they would change out the glass...
So here are the images from the front - note in the last shot that you...
Hi Garrett,
What exactly do you mean by "knurling at the base fillet"? I can take some detailed shots tonight.
So I got this lens the other day and am wondering what the experts may think it may have been.
The specs measure to be 7in f3.5
As you can see it has had surgery to remove the rack and pinion...
Quick update - so far loving the lens. Only shot it with the one Waterhouse stop I found in my stash that fir perfectly (about f5.6) and the results are excellent. Need more portrait shoots to try...
HA! Antique stores around where I live SUCK BUTT! Southern California is NOT a place where this stuff exists - period. But yeah, it'll come my way :)
yeah... that's about how it seems indeed. I mean, I'm not a big speed fanatic, f4-5 is plenty for me, but I like a slight swirl (and sometimes like it stronger than slight) and with Petzvals it...
Ummm... and where's my Euryscope?.... :'(
Hehe - it's ok - I have #5 and #7, so I'm fairly well set.
That 14" G&C does look impressive! That's what I need to find now - any 14"+ Petzvals. I...
Umm.... very sorry for the photos being upside down...
Interesting thing that I discovered while trying to see if there's a signature - the front element group is cemented in and the back is stamped in, no way to unscrew anything. Edges of the glass...
Hi Steve and thanks for your input - that's exactly the logo on the lens (of which I'll try to put a picture up when I get home). I'll also check to see if there's any markings on the glass...
