For 4x5" you will need an image circle from 152mm or 5,98". E.g. a Super-Angulon 1:5.6/75mm has an image circle of 198mm, so you can move 12,9mm verticaly and 10,5mm horizontaly.

That Cassar is a MF lens. It covers 6x6 only.

Lauren, ain't no cheap lenses for 4x5 much shorter than 90 mm. Ain't no fast wide angle lenses for 4x5, excepting the 75/4.5 Biogon (not cheap) and f/4.5 Grandagons (also not cheap).

One might be able to find a 3 5/16 inch or 82.8 mm Protar V (the shortest one made) for not a lot of money if not in shutter made by B&L. The Zeiss ones are getting pricey.
These cover 4X5 wide open (f/18). K

good luck finding something wide!
it took me a long time
to find something and then ...
i bought THAT center filter (new)
cost a small fortune as well.

it was worth it though, i use it (both) all the time
(on a speed graphic as well as a rail camera).

if you use it on a rail, don' t forget to get a deep-recessed
lensboard and something to fiddle with your speeds+stops.
if you don't have 4year-old's-fingers, you might find it hard
to make the adjustments.

I thank you all, for your help on which lens to buy, I was Lucky and found a Wollansak
E.W.A. 1:12.5 F-90mm which according to info has 84 degree at wide open and 100 degree stopped down should work , Now all I have to is improve my shooting: Lauren
