The lens has a big DOF, I can have everything on focus, at f22 from 3 ft to infinity.

ahhh, I see. The viewfinder, a doorviewer lens from apartment doors, actually produces comparable compositions to the 47mm lens?

Incredible DOF, as expected from such a short lens (although for the same magnification ratio of a given object, dof is the same or very nearly so for all focal lengths, it is just if you are the same distance).

My widest angle is a 90mm on 4x5.

Not quite, I made a mask with black tape to suit about the same lens field coverage. As to those aspects of DOF, I know very little about the issue. I spend a lot of time shooting, developing and in the enlargers, I should study a little bit more photography but I'm a professional musician, composer and record producer, so, I don't have much time sparing. Anyway, I think this photo will be reasonably sharpen untill a 16x20" enlargement.

This is a home made 4x5" camera, kind of a point-&-shoot, no movements at all and no focusing system, it's fixed focus at about 10 feet. I used f22 aperture. The camera was positioned on tripod about 1 1/2 foot from ground.

Nice shot Nana! :) so, If I understand you have you focus at hyper focal distance for a 47mm lens ...?
I was thinkin of makin a simulated Hobo point&shoot 8x10 w/ 115mm, the Hobo's I've seen had 90mm lenses

Right, Steve. You can find the right focusing distance for 8x10" format and 115mm lens here: http://www.dofmaster.com/dofjs.html

I think it's a good idea to build a 8x10" camera with a super wide lens that covers the entire format. I'm not an enthusiast of those round 90mm lens images on the Hobo. I have plans to build a 5x7" P&S camera equiped with a 90mm lens.

very very nice work

Spring Along Eagle Creek

Delta 100 developed in Pyrocat HD
Print on Ilford MGIV toned in thiocarbamide

^^ Wow, nice! I know some folks don't like Delta 100 shadows too much but (in pictures online) I find Delta 100 highlights to be "sparkly" for want of a better description. I think I'll try some in 8x10 when my TXP runs out.

Oh, I might add that these Fomapan examples look really great too re: Nana!

Thank you, Rory

Fomapan 100 is a little bit "tricky", especially it we overexpose it but, if the exposure and development is ok, the film is great. It's very cheap.
Another problem with this film is the huge reciprocity failure. At 100 s indicated by the lightmeter, you have to expose it for 16 minutes!:eek:
