View Full Version : 150 mm for 5x8

I currently have a 150 Sironar S that I used on my 4x5 and also used on my 5x7. It covered 5x7, but not by much. Now I thought I could use it on my 5x8, but it just will not cover. I think it has 231mm of coverage and the 5x8 takes about 245mm if my math is correct. Without getting into the huge 150s that cover 8x10 (I have the Nikkor 150SW) what modern 150s are out there that would cover 5x8 and fit in a Copal 1? If my research is correct, it looks like the Sironar W and Super Symmar HM might be the only games in town. Both are around 252mm in coverage. Any suggestions? Thanks. Jim

Should not need to do math to find the diagonal. Just measure it.

If you want compact and inexpensive, I'd go with the Fujinon 180mm with inside lettering. 305mm coverage and just a little bigger than a regular 150.

Old angulon 165mm will cover. Dagor also.

The 150mm G Claron covers with much room to spare. The smaller full aperture has never been an issue for me, but I have a Maxwell screen. On a plain gg you might have an issue with that.

The APO and L versions of the Symmar are spec'd as 5X7 lenses by Schneider, but you'll get more useful coverage out of the Claron.

Jim, you want a lens that covers at least 80 degrees. The more the better.

Think what you will of manufacturers' coverage claims, Rodenstock doesn't claim that the 150/5.6 Apo-Sironar-W covers that much and Schneider doesn't claim that the 150/5.6 Super Symmar HM does either. Same goes for G-Clarons, although enthusiasts insist their coverage is much greater than Schneider claims.

Image is from a 150mm G Claron, 2 inches of front rise. Yes, I insist it has more usable coverage that Schneider suggests.

Computar 150mm f9 would be a fine choice. It's tiny, and just misses the corners on 8x10.

+1. It's my most-used wide for whole plate, would give ample room for movement on 5x8. A bit hard to find, though.

Depending on your typical focus distances and how much movement you need, the Apo-Sironar(-W)/Sinaron-WS might be OK - I use it routinely with some movement on 5x7.

I believe all 150mm Graphic-Kowa are exactly the same as the Computar... easier to find and cheaper.

I was searching this info online this afternoon and what I found tends to say they both have the same amount of coverage. While my eyes prefer a 5.6 lens, the Kowa Graphic might be the way to go. Now to find one. Thanks to all for the info.

Interesting if true. There are no 150/9 Kowa Graphics (or Graphic Kowas) on eBay this evening. There is a 305/9 in Copal 3, BIN price $1,111. Google found no 150/9ers on offer in the last year. No 150/9 Computars, either.

Good luck chasing mythical beasts, Jim and don't even think about bagging one for a reasonable price.

The (few!) 150 Computars I've spotted over the years haven't been particularly expensive - it's the focal lengths that will cover ULF that make people go ga-ga. But the 150's have indeed been... few.

The Fuji 150mm W series lens with the lettering on the inside, is listed as 80 degrees, and has a stated coverage of 245 mm. That just might be an option for you.

Dan, if anyone knows In figured it would be you. I've read many times that the 150 G-K is the same exact design as the original Computar... the only focal length that never changed.

159mm Wolly, though perhaps not as modern as you'd prefer...

Dan,

Actually, one of these mythical beasts (150 Computars) is going to land in my lap at (what I think) is a reasonable price. I guess it doesn't hurt to put a WTB ad on the For Sale/WTB forum. The lens has 290mm of coverage and should work just fine.

All of this talk about the 150 Computar spurred me to move my barrel 150 Computar cells into a Compur #1 shutter with a very nice round aperture. Of course, the cells fit properly but the shutter needs work plus a new aperture scale made. There's a very good chance I'll sell my 150mm Apo Symmar-L and keep the Computar.

BTW, those who might worry about using common filters with the 150-210mm Computar/Kyvytar/Graphic-Kowa lenses... don't. There's a very cheap and easy fix for that via step-down and coupling rings. For instance, if using common 58mm filters, buy a 46-58mm step-down ring plus a 58mm female-female coupling ring. Then screw your filters into the latter. Just be aware that the step-down ring will screw too far into the shutter so either be very careful or add a tiny bit of Locktite to the threads of the step-down ring to lock it in place.

Great! Sometimes look and you will find works.

I recently bought a real nice example of one of these but in a Copal Press shutter. I got it from Japan and with shipping it was just over $150.00.

Cheap Cheap, Dirt Cheap as the Dirt Cheap Liquor Store commercials say here in St. Louis! ;)

Coverage of a lens, in general, is set to a level focus to infinity, and f number value of 22.
But the coverage values are variable.

If you focus closer to infinity (15 to 20 m away ... or less) its objective focus and also cover a much larger format (even 8x10 ").

It will be necessary to close some value nºf (f: 16 of: 22 to avoid much darker corners than the center of picture) a balance of light in the image plane.

You can use your 150 mm lens. But not infinite.
