Fast triplet with no aperture? probably a projection lens.

Coverage? I have a 145mm/f1.2 projection lens (on what was once a Speed-Graphic) that would barely do 6x12 at infinity...Not trying to sound negative or anything....:)

I've already purchased one :D They told me that they are guessing it has about 8 inches of coverage (from when they were checking out the lenses) , plenty for 4x5 :)

Only problem though, is that it's larger across than any of my front standards! Will have to work something out, haha!

Put the monster in a sinar 8x10 and use it as a 4x5. That is to say, use it backwards - use the back of the 8x10 as the lens standard and the front for the ground glass.

I'm looking for 8x10 rear standard and bellows for my cambo 4x5 to do exactly just that :)

I have seen a couple of complete Cambo 5x7 cameras on eBay lately at what looks like a fair price. The back plate of the 5x7 is a bit more than 8.5 inches square. More importantly I suppose is that the opening inside the back is 6.7 inches square.

Now this is a real monster. Weight is over 3kg. DOF is so shallow it's barely unusable. A big and somewhat expensive magnifying glass ;)
Some test shots on 8x10 with it for those who might be interested (hand held with the help of a friend on a 8x10 Linhof GT)
