I have found a 150mm f2.8 Leitz Elcan six-element, ctd. mounted on a Graphic lens board and is removable. It is only a barrel lens with no shutter apparently. Can shutters be place in this lens? Ad says it will cover 2.25 x 3.25. I guess if the back shutter is working it might be useable without a front shutter. The price is $179.00. Is this a useable lens at a decent price?

Ed, if you can wait another couple of days I should be able to give you a definitive answer. I have one coming from the UK that was sent surface mail on 11/4, should arrive any day now and when I have it I'll have a better sense of whether it can be used on a 2x3 Graphic.
That said, putting an aerial camera lens like the 150/2.8 Elcan in shutter will require expensive machining. To the best of my knowledge the lens' elements aren't in cells that screw into the barrel. At any rate, those of the 1.75"/2.8 Elcan I have at home aren't.
One of my friends has a 6"/2.8 Elcan. He tells me that the barrel's diameter at the rear is ~ 62 mm. The 2x3 Pacemaker lens throat is ~ 48 mm x 48 mm. So the lens will have to be hung in front of a 2x3's front standard. He also reports that the back focus (rear element to film distance when focused at infinity) is ~ 50 mm. The 2x3 Pacemaker Speed's minimum flange-to-film distance is 2 7/16".
In short, this lens that can't be made to work on a 2x3 Graphic. I probably made a $20 mistake, will certainly survive. If you want to make a $179 mistake, that's fine with me, and I'm sure it will make the guy in Albuquerque quite happy.
I shoot three (38/4.5 Biogon, 4"/2.0 Taylor Hobson, 12"/4 Taylor Hobson) going on four (1.75"/2.8 Elcan) ex-aerial camera lenses on 2x3 Graphics. None of them could be adapted easily or cheaply. To give you an idea, a shutter and machine shop work to make my Biogon usable -- it came in an odd non-standard unusable shutter -- cost $500. They're not, in general, quite the wonderful bargains they look like. But then, all of mine have been steals. The one in Albuquerque, if that's the one you're contemplating, isn't.
Sorry to be such a wet blanket,

Ed, my 3"/2 and 6"/2.8 Elcans arrived today. Short answer, the rear sections of their barrels o/ds are, respectively, 61.4 mm and 61.8 mm. They won't clear a 2x3 Pacemaker Graphic front standard. Back focus -- end of barrel to film distance at infinity -- is too short for mounting either lens entirely in front of the board to be practical on a 2x3 Speed. Flange to end of barrel distances are, respectively, 53.5 mm (3") and 55.0 mm (6").
Since back focuses are on the order of 45-50 mm, both can be mounted normally on a 4x5 board and shot on a 4x5 Speed. The 3" doesn't cover a lot more than nominal 6x6, nominal 6x7 at best. The 6" covers at least nominal 6x9.
Now that I have the lenses in hand, I'm confindent that putting them in shutter will not be economic.
If you want a normal lens for a 4x5 Speed, the 6" isn't for you. And neither can be used on a 2x3 Speed.
So I have two more paperweights, but the price was right and now I know. I'd been wondering about 'em, now I know.
Good luck,
Dan |
