This 90/8 SA will be my first experience with a Wide Angle Lens on a view camera. I really appreciate that advice David. I just printed it out and threw it in my camera bag! Thanks. Shawn

Fuji still makes the 90mm SWD F/5.6. It is a good choice, used it is slightly cheaper than the Nikon and almost as bright.

Sic gorgiamus allos subjectatos nunc.
i've been having the same dilemna...
I think that I'll end up settling on a 90mm 6.8 grandagon though. its not too small, yet not too big like the 90 4.5 nikkor/grandagon/5.6 XL SA.
the SA would be my second choice.
somehow, the Grandagon seems to give a bit more warmth the right areas for me. I've been using one from school on one of their Toyo monorails, and all I can say is that it is a treat to use.
as stated above, if you don't have a W/A fresnel lens, focusing/composing in the corners can be a PITA, but I've found that by looking at the g/g at a slight angle helps a bit.
best of luck though. I was so set to drop the cash for the XL SA a while back, and I wouldn't have regretted it today if I had gotten it. but my methods have changed, and what I shoot has changed.
Currently saving for a master technika 2000/3000 though, with backpacking 4x5 eventually. so the 6.8 grandagon would help, due to its smaller size.
best of luck!
The 90mm f6.8 Grandagon is an excellent lens, it's possible to finf the Caltar re-badged version at good prices.
David makes a good point about the hot-spot which is even more noticeable as you use wider lenses and this is wherea goof fresnel makes a huge difference.

Adding to Ian Grants good advice
A decent Darkcloth helps enormously - as you need to wrap it around yourself and the Camera to make everything behind the Camera as dark as possible to see into the corners.
Also you need to learn to "bob" your head up and down and sway it from side to side to find the best viewing angles to help look in to the corners - although you will look something like the village idiot doing it :rolleyes:
I know you are looking for a 90mm. I have been using a Nikkor SW 120mm f8 with 4x5 which also covers an 8x10. I don't know what they run but it's something to think about since you also mentioned that format. It's very sharp but would also be heavier than the 90.
Tessar type lenses have poor coverage so a 90mm Commercial Congo most definitely wouldn't cover 5x4, however the f6.3 90mm Wide Angle Congo may be slightly better than the older Angulons but it won't be as good as a Super Angulon or Grandagon, or the other lenses mentioned.

While most people complain about the f/8 being too dark to work with, it's not the "lack" of light, but the spreading of the light to the ground glass which is the problem. That problem will be just about the same with a f/4.5 lens. It's all due to the lens being so close to the ground glass and that as soon as you look somewhere not centered between your viewing eye and the lens, there will be severe light fall-off.
The cure for this is a fresnel lens, which will set you back maybe $50 or so for a used one, unless you already got one. The plus points are: much smaller lens (the f/4.5 lenses are huge), smaller filters (95mm or so for the f/4.5), similar performance, etc. The f/4.5 lenses covers some millimeters extra, but at a price, weight and size penalty.
When using a longer lens, like 240mm for 4x5", a Fuji A f/9 is very easy to focus and compose. The difference is very small compared to e.g. a Heliar f/4.5, which should be 2 full stops brighter, but that is very hard to notice.
Björn, I've used a Ross f16 Protar 151mm on my 10x8 camera and with a Beattie screen it's easy to focus even in room lighting with no dark cloth.
Likewise I can easily focus an f6.8 90mm Angulon and an f8 75mm Super Angulon on my Crown Graphic working hand-held, since adding a fresnel, prior to that it was a little hit & miss/almost impossible but I was lucky. I have an 5f5.6 90mm Super Angulon and it's only marginally eaier to focus than an f8 lens. The screen itself and whether it's plain glass, glass + fresnel or super screen makes by far the greatest difference. There's a measurable 3 stops difference between my Wista screen and the best plain glass screen, the plain glass improves by over 2 stops when a fresnel is added. Obviously the hot spot is the same brightness regardless, but the other 95% gets close with a fresnel.
