I'm guessing that 80mm you're talkiing about is a Schneider 80mm f/4.5 Super-Symmar XL. It's a newer and more complex design than the other 75's and 90's you're seeing, among other things.

I'm guessing that 80mm you're talkiing about is a Schneider 80mm f/4.5 Super-Symmar XL. It's a newer and more complex design than the other 75's and 90's you're seeing, among other things.
The biggest difference in 75's and 90's is coverage.
For the most part the larger aperture ones have larger coverage for movements than the slower ones.
I think the f/4.5's incredible, but...
If you want to experiment with how film format, aperture, distance, and magnification affects background out of focus blur, this website is fun:

I have the same set! Well, nearly. I don't have the Super Symmar and my 165mm SA is multicoated. But I certainly enjoy using them!
That's a good point! Which horse's mouth indeed! Schneider also published data on IC that states ~429mm for the 165!

I can't imagine how soft those corners were!
I can say that the...
f/16, not f/22. Schneider's data is for f/16. And in this case, Schneider is the proverbial "horse's mouth."
Also, modular transfer function improves as you stop down across the frame, so IC...
The Angulon 165's IC is 300mm at f/16. I have a late one in a Compur Electric #3. It makes a nice moderate wide on 5x7 with lots of room for movement, but it will cover 8x10 at f/22. There is no hard...
Yeah. I've always wondered if they were measured at different f-numbers, but I've never had an inside writing Fujinon W to play with and test.
This is a good example of how contrast affects apparent sharpness in ways that matter more than actual resolution.
Reminds of me of this essay on sharpness and pinholes and deciding what size is...
For what its worth, the 300mm W with inside lettering may get a listing of 420mm IC, but it also gets a angle of view for coverage 80° vs. the 70° of the 300mm W with writing on the outside ring.

The Fujinon A 300mm weighs 410g.
The G-Clarons mentioned are also great for a lower price.
If those are your parameters and budget isn't, I'd recommend a Fujinon A 300mm f/9.
Super well-corrected, 420mm image circle.
The more rare Fujinon A 360mm f/10 will give you a 500mm image...
There are the Schendier 360mm f/5.5 Tele-Xenar & Tele-Artar. Both heavy. The Artar is better, but also heavier.
Nikkor's 360/8, 500/11, 720/16 trio is really really good and has the advantage of...
He's a university faculty member, his job is teaching photography and art, so I would expect that there was public funding for this grounded in engaging the public with the arts.
This was probably our last chance for drinks outside before it gets too cold.

16"x12"x2". My current hangers work fine, but they're just spring wire bent into a rectangle with clips to attach to the film on them. It works, but I need a better system...
I built my own tank for 11x14.
I had to make my own holders for the negatives in order to make it work.
I used 1/4" acyrlic like what's used for larger fish tanks. I chose a size to do two at a...
All this talk is making me want to build an 14x17 back for my 11x14.
The Falcon Eyes RX series are nice and small with plenty of output.
Picking up a copy of Rudolf Kingslake's (1989) A History of the Photographic Lens would be worthwhile!

That's definitely the best way to get *INTO* ULF!
And there the small few for whom it's both!
If you're looking for the speed for doing portraits, you also probably don't need perfect coverage at infinity.
A 300mm f/4.5 Tessar/Xenar will cover the 11x14 for anything from head shots to...
I posted this in the Show your ULF camera thread, but it should be here, too. :)
My Bender 5x7 (originally 4x5) and my 11x14 "folded" into its traveling form.
The 5x7 uses 15mm rails designed...
I just barely qualify for that. This was four years of trial and error that any sane person would have given up on six months in.
"Cut twice; measure once," I always say. In that order.
Here's my contribution: Homemade 11x14, along side my Bender 4x5 kit converted to 5x7.

If its a Symmar-S MC, it doesn't cover 11x14, you get completely black corners at infinity with that lens.
On movements...
The Nikkor T 800mm, since it is a replaceable rear element design (600, 800, 1200), actually functions in the same way as a teleconverter does for 35mm cameras. So you're actually...
What are the other lenses in your lens pouch?
And also: I want that lens pouch!
56mm smells like a #3S to me.

Yes.
Though you'll need to consider the lens you're transferring. Many Schneider lenses that were originally designed for Compound #3's were later used in Compur Electronic #3's still kept the...
This site lets you simulate angle of view, DOF for various focal lengths and subject framings from tiny digital sensors all the way up to 11x14:

When it comes to learning ultra-large format, having cheap practice film is necessarily part of the best case scenario!
The best way to use the double sided stuff, in my experience, is in a vertical tank to avoid scratches. I built one out of acrylic for 11x14.
Score it and snap it!

I converted a Bender 4x5 kit to 5x7 and made some tweaks, but I think I'm going to have to borrow some of these--especially the locking washers. I like that idea.
One thing I did for stability and...
This fellow has a series of videos going through the whole process.
But this particular one is about the RF cam for infinity focus: https://www.youtube.com/watch?v=l0UVQgQ2Ppw
