I am looking for a lens for a projection project. It needs to be 100mm in
diameter or bigger, a focal length of 450mm and have a field of view of 40+
degrees. Is there such a lens anywhere? Or a lens that's close to those
specs?  Thanks for any help.

Dear largeformat users,
I am very new to this and have aquired a Sinar P....not sure why this
particular camera, but that is another story...:-)
I am trying to find out what is the widest lens I can use with the standard

I think I've narrowed down my problems with light leaks to a bad batch of
film from photowarehouse.biz.  It seems that 1 in 5 sheets of 4x5 had
fogging spreading from one edge where it was most intense to about half of
the sheet before it cleared out.  Over the last 6 months, I've ...

I suspect a light leak in one of my Regal or Fidelity 4x5 film holders.  
Before I fill them all up with photographic paper, what are the typical
culprits for leaking light?  Where is it most likely that light would get
in?

A good friend of mine put up his photography website a time ago, some
pictures are just amazing.
The design of the page is quite nice to, take a peek!

Hello Group -
Saturday evening I was photographing an elderly woman 4 hours from town -
when I opened my camera bag, lo and behold, the ground glass was in shards.
Pieces everywhere. I think the culprit was tossing the bag around with a

I have several old lenses I'd like to experiment with that don't
have shutters.  They are in a range of types and sizes from a big
fat aero lens to a tiny old Dagor, and probably won't all turn out
to be worth using, so something adaptable is needed.  I believe a

I have been hiking in the Colorado rockies with my photo gear
(1D Mark II digital and 4x5 cameras) in a LowePro Photo
Trekker AW backpack.  I've used this backpack for several years
from Florida to Alaska, but never in serious rain.  Well, the

How much is a package of Hahnemuhle Inkjet Fine Art Photo Rag 308g paper in
Germany? Ref no. 10 640 266/50 sheets, A3+.   Just curious. Thanks in
advance

I am interested in a 24" Red Dot Artar in a shutter.  If anyone has this
lens and is willing to sell please contact me at gchapple@pacbell.net.

I have 100 sheets of unexposed 4x5 film given to me by my dad. He has no
idea at what ISO the film is rated, only that is E-6 process. I tried to
compare the notching to many known films, to no avail.
I want to conduct some test shots in the studio under precise lighting in an

Do pinholes matter, and if so, how much?  Are they worth the expense of new
bellows?  I took a few pictures, and they seemed all right, the nagging
question is how much better would the image be without pinholes in the
bellows.

I recently bought some Polaroid MP-4 Lenses. These are optimized for 1:1
or greater magnification, and I intend to use them with 35mm gear and a
bellows. The MP-4 lenses cover 4 x 5, so I should be able to use tilts
and swings in the 35mm macro format. Once I got them mounted, they ...

I got ahold of the new Velvia in 120 and 35mm. I've shot about tree
rolls total out of the six I initially bought. It appears to have really
fine grain on the light box and scans very well. The impression I have
of the color is that it quite accurate to the  way my eyes ...

   I see the Arista Sheet films (Ilford FP4/HP5) I'm so fond of are being
replaced by another film called Arista II ( ? on manufacturer though they
still make reference to England as origin but not Ilford apparently)--as
well as the printing paper which I assume may now be produced ...
