Ditto brass flat head...

Made up one. anyone what one?140189

I coulda sworn it appeared here and I saved it, but I can't find suchathing here on in my own files. :(

I have a perfectly functional one of these that I've had since the 70s, but the battery door is gone and I have to press the 9V up into the recess while making the reading. I got another meter on...

Interesting...that may explain things I've seen with CFP and digital cameras...I can't say I've encountered this with linear polarizers and film. I generally have two interests: shots with sky, in...

I've been using Laumont for 2 years now, and I don't think I've ever seen their enlargers in use. A shrine of sorts...but really, printing digitally from digital scans...of analog film has so much...

From B&H new, a B+H is $500+, more than half what I spent for the lens. I do love polarizing filters and am trying to figure out how to achieve this in some simple and affordable fashion. In the...

In NYC, I strongly recommend LTI Lightside for large format E-6 processing and Laumont Studios for scanning and lovely jewel-rich color chromogenic darkroom prints. I have worked with both and found...

I have some cheap Coleman polaroid sun glasses. When at the angle to cut out reflections, the ones it does pass are blue. As sunglasses and I seem to break up often, I never spend much money on...

I looked up the actual bellows length I'd need for a Nikkor ED T 1200mm telephoto, which the spec sheet listed as just under 800mm Rudy said that the normal Sinar bellow length is 700mm, but that he...

Side note : I also play the concertina (the little hexagonal squeezebox) and have had much experience there with patching and replacing bellows. There the problem is wheezy bellows losing air *and*...

Any have experience, recommendations, suggestions on replacement 8x10 bellows for Sinar F?
1) Do all models of the Sinar (F, C, P) use the same bellows? I understand there are metering and...

Mine appear to be permanently mounted to plate which is in turn mounted to the standard, rather than just a vial that pops into a standard, the former I gather is the way it's done on the F, while...

Thanks all!

Would anyone be able to tell me the filter size for

210 Angulon
600mm ED T Nikkor...There is information here on page 10...but it's unclear to me which dimension is for the screw in filter
...

...and in poking around looking for this information, I found this auction from 2014 of a full set or all 3 focal lengths that went for $650. Moan....

Thanks!!!

I purchased a Nikon ED T 600-800 set.....which only has the aperture legend for those two focal lengths. If someday the gods smile and send the 1200mm rear cell my way at a reasonable price, I'd...

Thanks all! As always, complete and authoritative answers!

I have a Sinar frankenrail...it's an extension rail that was sort/kinda turned into a base rail by somehow lengthening the center screw. It looks like this:
131859\
As you can see, it stick OUT of...

Anyone? I have a frankenrail with the too-long center screw that I need to cut down or replace...
Thanks in advance.

As always thanks to all for definitive, informative and expert commo...........
I got a 600-800

There appear to be two versions

A 360-500-720 version
a 500-800-1200 version


I may not have the focal lengths exactly right, but they are in that range. Can someone tell me what the...

Well...if I look at the end of a 16" extension rail on ebay, I see this:
131597
where the screw is recessed, unlike mine, which sticks out
131598 131599
So the extension that came with my F is...

Thank you, fishbulb, for all the thought and care and effort that went into that comprehensive reply. I am still puzzling out the rails....looking at my rails and the two different base and extension...

I recently got a lovely Sinar F 8x10 on Ebay. I have long worked with wooden cameras (2Ds and a Gundlach), but most everything with the Sinar seems pretty straightforward. I have these questions.

Thanks to all for the good advice!

As I said way back in the beginning, I have an uncoated process 1000mm Dagor...what with its weight and the 1meter foical length at in infiinty (never mind closer), it's unsuited for field work with...

I'm used to making my own lens boards of 1/4" or 1/8" masonite...and have the hole saws, table saw and drill press to do it well.
Can you DIY make Sinar lens boards for the F/C/P...of wood or metal?...

Yes.

Any suggestions? I use a 300 Symmar for my normal lens, a 210 Angulon for WA, but the Tele-Xenar I have exhibits nasty chromatic aberration. I also have a 1 meter Dagor, but it's a weight monster,...

For what it's worth, should anyone else be pursuing this, the strength of a solenoid may be rated in Newtons. A newton is equivalent (I think) to a 1/4 pound or 4 oz. While a force of about that...

A relay similar to the one I used, but with the timing adjustment on the relay itself, is available used on Ebay for $62 + ship. See also the 'also viewed' other P&B timing relays.

Looking at this Sinar on Ebay. Wondering:

What model is this? This seems like a great deal.
How does one attach it to a tripod (there being two mounting pads)? Or is it missing a center clamp...

One more picture....you're only allows 4 per append

I'm kinda busy...been going out to Colorado to see a lady friend and take pictures (this time in large format) of the Poudre River...

Back 30 some years ago, I built a timing rig using a commonly available P&B timing relay to run a big solenoid operated Packard shutter.

I did a lot of work with this which you can see...

I'd be interested in one, in for $100 or perhaps more. Another design possibility is the scads of timers available from HongKong through Ebay, like this. Alas, the load contacts are AC...
