How hard are the Leitz 9X12 easels to find (whats a fair price) - -----Original Message----- From: owner-leica-users@mejac.palo-alto.ca.us [mailto:owner-leica-users@mejac.palo-alto.ca.us]On Behalf Of Anderson, Ferrel E Sent: Wednesday, November 08, 2000 6:45 AM To: 'leica users group' Subject: [Leica] Automatic focusing with the iC enlarger Since someone else is offering to send you the instructions for setting up the autofocusing on the 1C, I will just add the following basic requirements for achieving autofocus: 1. You must use a Leitz 50mm f4.5 Focotar, or an older 50mm Elmar enlarging lens, or a 50mm Leica rangefinder lens, which require special adapters. The common denominator is that the focal length has to be precisely the Leica 50 mm focal length, whatever that is, and the 50 mm Leica lenses l listed above all have that. I don't know what a Fotar lens is, and if it is not a "Focotar", and if is even listed as 50mm, it probably won't work throughout the full focusing range. Other brand 50mm enlarging lenses won't work. 2. The Focotars require the extension tube to work properly. I can't remember the catalogue number. 3. The pin on the column has to be in the proper hole. The upper position is for use with a 25mm thick easel - i.e., a Leitz 9x12 inch easel. The larger (12x16 inches) Leitz easel is 30mm thick, and requires a 5mm spacer ring on top of the pin to achieve the proper distance from the easel. IMPORTANT!!: The spacer ring is also required on later Focomat 1C enlargers if you use the original Focotar with the writing on the front of the aperture ring. The later Focotar lenses have the writing on the side of the barrel. The pin is placed in the bottom hole if you are printing with the paper placed on the baseboard without an easel. Ferrel Anderson
