So, it looks from Mamiya's site
(http://www.mamiya.com/html/customer_service/servicerepair.html) that I'm
just supposed to box up the camera, include a letter describing the repair
request, include payment information, send the box to them in Elmsford, and

What is considered to be the minimum resolution in lp/mm for an
enlargement to still look OK? Do I hear "5 lp/mm"?

I can't seem to get flashbulbs to work reliably with my commie
cameras.  actually, my Kiev 4 and my Moskva 5 are the ones I am
interested in (fed is hot shoe only).  electronic flash works fine on
both, but a bulb never seems to go off.  on my Zorki 2 it works

Like the title says... preferably the N version...
Thanks!

hassie when happens a strange thing: the 80mm unscrew in my hand ...now i

Can anyone recommend a decent cheap MF projector for 6x6 slides? Only

A question for all readers and medium format photographers - does a

start something like that?

I just purchased a Rolleicord IIc and shot my first roll of film (Forte 100
B&W). I am not sure the wind knob is working corrrectly. There is no film
advance stop and the button in the center of the knob doesn't seem to do

superachromats. The latter offers the ultimate in color ...

I am hoping for advice.
I had my studio lights set up in a new area and the gossen starlite had a
dead battery. I replaced the battery but some of the functions like changing

I just bought the RZ67 pro II kit and would like to aquire the system

I loaded the film in accordance with the instructions, lining up the START

I've noticed that there are quite a few cameras, mostly produced before
WWII that were specifically designed for glass plates.  In fact many of
them have no ability to load rollfilm, even with a holder.  I know with
