andrew_pell Posted January 29, 2003 Share Posted January 29, 2003 Hello all, I'm trying to fit a 150mm f4.8-16 Boyer Saphir enlarging lens to a De Vere 54 enlarger (not a 504) and am going to need an adaptor flange turning. I know this seems obvious fitting an enlarger lens to an enlarger but the only info I can find about Boyer on the web is for taking lenses (and it still doesn't mention thread sizes :-( .) Can anybody confirm that the lens thread is ø1.75" x 1mm pitch and for that matter, the enlarger is ø2.5"-16TPI 55° BSW? If they aren't these sizes, does anybody know the official sizes as I'm getting nowhere on the net? Thanks Link to comment Share on other sites More sharing options...
jay_lynch Posted January 29, 2003 Share Posted January 29, 2003 Your best bet is to send it to SK Grimes. This way you know it will fit instead of wasting time and money tring to rig something yourself. I was just looking to mount a lens for my DeVer 8x10 enlarger and ended up wasting a lot of time and money. When I should have just sent it to Mr Grimes. I think he was going to charge $35 Link to comment Share on other sites More sharing options...
andrew_pell Posted January 29, 2003 Author Share Posted January 29, 2003 Thanks for the info Jay - the only fly in the ointment is that I'm in the UK and things might get a bit expensive sending items over to the US (especially the lens as it's "solidly built.") I can hopefully provide my own material and have a couple of local machinists I can call on who should have the capability... I've already bought an M39 adaptor from Odyssey Sales and that wasn't the cheapest of things (50 GBP all in) and tried getting hold of one from somewhere else for the Boyer but they sent the wrong one :-( The incorrect one is of a flat plate design 1/4" thick with an internal and external thread so has a lot less operations to manufacture than the M39 one (cup design with knurled edges etc). I might hold on the incorrect one for now in case it fits any of the other lenses I have when I check. Thanks Link to comment Share on other sites More sharing options...
dan_fromm1 Posted January 29, 2003 Share Posted January 29, 2003 Andrew, Ian at SRB Film Services (www.srbfilm.co.uk, sorry, I don't have the phone number or his surname ready to hand) just might know the answer to both questions and is a lot closer to you than Steve Grimes.

andrew_pell Posted January 29, 2003 Author Share Posted January 29, 2003 Dan, I'll have to give Ian (Broadhead?) a call - I've spoken to him before at various shows and hopefully they're going to Focus on Imaging in Febuary. They might have something off-the-shelf... Andrew Link to comment Share on other sites More sharing options...
andrew_pell Posted January 29, 2003 Author Share Posted January 29, 2003 correction - it's Ian Broomhead - I was close ;-) Link to comment Share on other sites More sharing options...
dan_fromm1 Posted January 30, 2003 Share Posted January 30, 2003 Another thought. Colin Cox at The Camera House. Possibly www.the-camera-house.co.uk , best to do a web search. He has a heap of adapters, I recently bought a couple from him. Seems nice, not sure he knows a lot though. Cheers, Dan Link to comment Share on other sites More sharing options...
andrew_pell Posted January 31, 2003 Author Share Posted January 31, 2003 Thanks for the alternative suggestion - Oakworth isn't a million miles away. I managed to get hold of some ø80mm aluminium round and have a friend who has a lathe so that's another option to try if he can get the correct pitches set up etc as it's a manual machine.

edward_zimmermann Posted February 3, 2003 Share Posted February 3, 2003 "<cite>I'm trying to fit a 150mm f4.8-16 Boyer Saphir enlarging lens</cite>" <P> Curiously I've just started "<cite>playing</cite>" with a 9.5cm Saphir-B enlarging lens. I was under the impression that the Saphir were all Tessar (Triplet with glued rears) types but looking at this massive (single coated) 1:3,5 objective I'm tending to suspect its another design. I have some testing to do but casual trials (with an ancient Schneider test negative) hint that they are nice. I'd call it a very French lens as the manner of brass and the general feeling of it reminds me of SOM Bethiot. <P> "<cite>I can find about Boyer on the web is for taking lenses (and it still doesn't mention thread sizes)</cite>" <P> The one I have, to my eyes, is clearly an enlarging or copying lens. It has extremely recessed M39 threads, viz. its rear element extends significantly behind the mating flange. Link to comment Share on other sites More sharing options...
ernst_dinkla Posted March 23, 2003 Share Posted March 23, 2003 15 years ago I had a French Reinhel 4x5 enlarger/camera for graphic art work. That one was eguiped with 3 Boyer Apo Saphirs on a turret. Tessar type lenses with openings starting at 9 if I remember it correctly. All brass including the flanges. Sold it after I converted an even bigger Autom Zuchiatti separation camera to a graphic enlarger/camera. As far as I can tell the flanges of the Boyers were interchangeable with some other enlarger lenses like the Componon of the same size that I used on the last enlarger. This is French stuff so the thread has to be metric. Ernst Dinkla Link to comment Share on other sites More sharing options...
