Fuji 250 6.3 or 250 6.7, I am confused? Is one superior to another in 8x10 Use?

[Harlequin]

Hello

I was wondering what the differences were between these 2 Fuji lenses.

A) Other than aperture, is there a big difference in image quality.
B) If using on 4x5 for portraiture, would there be a best choice between the tow.
C) If using as a moderate to wide normal lens on 8x10, which has a larger image circle
or do they both "cover" 8x10.
D) Any sample images from these lenses would be appreciated!!

I just don't want to make the wrong choice based on the uses I described above...

Thank You for your input and responses!!

F6.7 has a larger image circle..

There was one f6.7 -- single coated. There were two f6.3 models -- EBC coated. The f6.7 has a substantially larger IC. All three cover 8x10.

It's worth noting that the f/6.3 version is spec'd at just barely covering 8x10 at f/22, which probably indicates that coverage at a wider opening is doubtful.

I'd only recommend the 6.7 version for 8X10. But the tiny Fuji 240 A has just about the same coverage and is more common.

I use the 6.7 version as a wide angle on 8x10 and as a slightly longer lens on 5x7. Since it is single coated it should be a little less contrasty then the 6.3 version which is usually multi-coated. Therefore I expect the 6.7 version should be better for portraits. Also the 6.7 version has better coverage on 8x10.

They used some special glass type for the 6.7, perhaps containing an ingredient now banned. I dunno. But that lens has higher contrast than most multicoated plasmats of similar vintage. Great for color film too.

Maybe the ingredient is magic pixie dust?

Just kidding, but I like mine. They are a bargain! I've seen them go for $200 on Ebay. Jock Sturges used one for his early work.

Back in the 1960's Minolta, Pentax, and others added rare-earth, radio-active elements, such as thorium and lanthanum, to some of their super-fast lenses (ex. 58mm f1.2) to increase the refractive index. It's possible that Fuji did some of this as well, but if they did, I'd be surprised -- but not shocked -- if the 250mm f6.7 was one of them.

I think you will be happier with the 6.7.
This is the list of 8x10 Fuji lenses I have tested, I'd recommend getting all of them! I think the market price of some of these have actually gone down in the last ten years since I started 8x10.
