8x10 Lenses Most Used, Most Desired

It depends on what you'll be shooting and how much you want to spend and how large of a lens your front standard (or your poor back, if you're hiking) can take. For vintage glass---as Jim Galli mentioned---the sky is the limit.
I shoot with a passel of old lenses---Ektars, Dagor, Artars, G Claron, Velostigmat, Nikon, and B&L.

The 240 G Claron is probably my most used lens because it is small and light weight and was one of the least expensive to purchase.
I also use a 250 Widefield Ektar mostly for architecture because it seems to have acres of coverage.

My "normal" lenses are a 14" Commercial Ektar and a 12" Dagor. "Long" is a 19" Artar.

A 360 Nikon M, 14" Artar and 159 Velostigmat yellow dot spend most of their time aboard the snouts of other cameras. The 15" B&L Petzval is just plain fun.

Any of these, plus many others(Fuji, Wollensak, Ilex, Schneider, TR etc...) would be considered desirable. It's not so much the lens, but what you do with it that makes or breaks a photo op (ducks and takes cover.)

Defining photographers' preferences is as elusive as tracking such foolish metrics as the Minnesota Multiphasic Personality Inventory. It's all bullshit.

A question remains: are photography viewers of a similar metric?

Would love to have a Cooke XVa Triple convertible lens. Just priced a bit much these days.

Over the years have always gone back to photographing waterfalls and streams especially in gorges. Shoot 8x10 film. Printed with traditional Silver gelatin paper up to a few years ago when I started to make digital negatives and print Platinum/Palladium and some Silver prints.

These 3 lenses are the ones I currently use:

240mm Dagor - little gem of a lens

12" f/4.5 Wollensak Series I Velostigmat in a Betax - the first lens for my 8x10 back in the 1970s. Also in the 1980s bought a 12 3/4 “ (18 7/8” 27”) f/7.7 BL Protar VII and a 14” f/7.7 GOERTZ DOUBLE-ANASTIGMAT. They both have huge coverage and are excellent optics but have always gone back to the 12" Velostigmat. The Velostigmat does not have the 1 to 6 front "soft focus" ring.

508mm f/7 Caltar - bought it primarily for my 11x14 but whenever i take my 8x10 out, the Caltar also goes with me.

If I really need a wider angle lens, I take along my 5.9” f/14 No. 5 Gray Periscope in a Copal. It actually covers 11x14 but its sweet spot is 8x10.

When I was printing on traditional FB paper, preferred to use G-Clarons but for Platinum/Palladium prefer to use older classic optics.

Always wanted to own a Trigor but never came across one that was priced reasonably.

The last time I did an 8x10 project, I used a 10" Kodak Wide Field Ektar and a 14" Kodak Commercial Ektar. The WFE got most of the use. I was unhappy to sell that system off, but it wasn't paying its way. Should I ever go back to 8x10, I'd look for those lenses again.

I mainly shoot 4x5 but I have been shooting some 8x10. In order of use: Nikkor 450 M lens, Nikkor 300mm M lens, 240mm Nikkor W lens, 19 inch red dot artar lens, 12 inch soft focus Wollensak Velostigmat lens with variable 0-5 settings, and 8 1/4 inch 1960's American Optical Co Dagor lens. I have been shooting nature close-ups to infinity images, some architectural - urban to rural images, and working on portraits. The image is what its about.

I only used an 8x10 for a couple of years, but I found that a 300 and a 19" or 20" (can't remember precisely what it was) did me for most subjects. I never owned a wide-angle lens for it, couldn't fathom the cost.

Most used is the 12" Dagor followed by a 9 1/2" Dagor. Wide to a 6 1/2" WA Dagor then long to the 19 and 24" RD Artars.

Most desired? That would be the Cooke XVa because Ansel had one, and the 19" Dagor f/7.7 because it's a Dagor and it has enough coverage to contain a Walmart parking lot. That's if most desired translates into what prices they demand from buyers. There are good reasons why cult lenses are highly regarded, but to dismiss more pedestrian long time industry workhorses just because Ansel didn't have one, or have the market cornered when it comes to some esoteric quality is, IMHO, just silly.

I have nearly the whole set of 80-degree Fujinon-W that cover 8x10. The 300, 250, 210, and 180. I don't know the current market, but when I first got into 8x10 these lenses could be had at bargain prices. For super wide I use an inexpensive Fujinon SW 125 and just crop a little when printing.
