Swapping LF lens
Hi all,
In a recent purchase of a LF camera, I received two lens, a 190 WF Ektar and a 12 inch Commercial Ektar. Both came mounted in #4 Acme shutters. The 12 inch Acme shutter doesn't work. I looked at the spacing on the shutters, they look identical. Any one see any reason why I cannot change the lens elements and the front plate (for aperture use) on the Acme? I don't need the 190mm right away, it won't cover 8x10 and for 5x7 I have a 150 Fujinon W 6.3 that should cover the WA 5x7 format.
Maybe one of the LF lens gurus can weigh in on this.

Sure, you can swap the lens cells and use your working shutter as long as the threads are the same. I've also got a 190mm Wide Field Ektar and it does cover 8x10--not with much movement, but it does cover. I'd get the other shutter fixed because then you'll have a very nice 190mm/300mm combination for your 8x10.

If the twelve incher is the same length, end-to-end, in both shutters, why not?
BTW, EKCo claims that the 190 WF Ektar will cover 312 mm at f/16, ~ 360 mm at f/45. See http://www.prairienet.org/b-wallen/B...kEktarsDB2.htm and http://yandr.50megs.com/kodak/ektar/page2.htm respectively.

So you need a minimum of 326mm for 8x10. The 190mm should be good at f22 and smaller.
Off to switch a front plate. The other Acme #4 shutter will be fixed. No reason to have one of those sitting around collecting dust.
In a related finding last night, I found a Speed-o-scope Jr that screws to the front threads of a JML 305mm/f9 lens I have. Time to make some more lens boards. It only has 3 speeds, but three speeds are bett'n none.

No 310 ish to cover 8x10.
Your JML has threads?? Luxury. My 210mm doesn't.

Neither does mine. I haven't figured out how to put a shutter on that one. It does seem a extremely sharp lens though, the 210. What a wonderful plasmat design.

All,
Along these line, Since Carol F. is taking a break, where is a good repair place in the SF Bay area? K&S in Palo Alto? Anyone have any recommendations? All I suspect this shutter needs is a good CLA.

k_jupiter,
For shutter CLA I recommend calling Paul Ebel at Lens Services:
420 21st St. N #2 P.O. Box 141
Menomonie WI 54751
(651)335-8759
Also, if you are getting a sharp image on the ground glass, that is confirmation that the spacing is okay.

Tim, I've often received good service from Apollo Camera repair in Oakland (1411 Webster Street). There is also a very good shop (better than Apollo actually but...) in Walnut Creek. I think it is called "Apex Camera Repair" or something...Anyway, it is two old timers in a little shop on Boulevard way. They do fantastic work at reasonable prices but, service time is highly variable...it might take a day, it might take weeks. The owner's name is Wally. He's kinda curmugeounly. There's an old german guy in the back too...
I avoid ICT in Mountain View. The old german guy who owns the place is a crook...tried to tell me that my Synchro-Compur needed a $175 overhaul. This was a completely operational, running shutter. I just wanted it cleaned and lubed for my own peace of mind. Carol brought it back to A-1 service for $50!.

If he wasn't curmugeounly I wouldn't trust him. I'll check out both places this weekend (or at least the Oakland place if it's open. Thanks for the info.
