Recessed 80mm lens board for a Horseman Super ER 1:7/65mm Lens

[James Kellar]

I have kind of asked this question before. I have a Hoseman Super ER 1:7/65mm lens that is now on a regular/flat 80mm lens board. I can get it to focus if I pull it back from the first (white) infinity stop. From what I have learned I believe I need a recessed 80mm lens board. I have searched Ebay and the web and have not been able to find such a beast. Another thought was to have one 3d printer. Does anyone have any thoughts and or suggestions on the subject?

Thanks
James

Finding just the board might be a challenge though it's probably the least pricey option. You might keep your eyes open for the same lens (but damaged) still mounted to the correct board.

Um, I just took a look on eBay, found ten (10) 65/7 Horseman (no Hoseman) Super Topcor (no Super ER) lenses on Horseman boards. Flat boards, all of 'em.

The Horseman catalog at http://web.archive.org/web/20160929...eraeccentric.com:80/html/info/horseman_2.html shows 65/7 Horseman Super ER lens on a flat board. See p. 18. The catalog shows 80mm x 80mm lens panels, none recessed. See p. 26.

Might you be mistaken about how to set your camera up? Might you be chasing a unicorn?

My 75mm lens is mounted on a recessed board, I think it may be that the previous owner used that infinity stop (White) with a recessed board in which case you will need to adjust the infinity stop to suit your flat board.

Interesting. When I was shopping for w/a lenses I was put off lenses for 2x3 Horseman cameras because their shutters didn't seem to have cable release sockets. Instead, as shown in eBay listings, there's a gadget on the Horseman board that accepts the male end of a shutter release and transmits the poke to the shutter's release lever. It doesn't look like there would be much room on a recessed 80x80 board for the gadget.

So, for curiosity, how do you use a shutter release on yours?

Just for information, 20 years ago or so, my friend had recessed boards made and sold them along with a kit to adapt Copal 0 shuttered lenses to them. They are long gone and quite rare. As I remember they only recessed the lens about 7mm and required some minor modification of the aperture setting lever.

If you want to use the rangefinder, get a lens already mounted on the correct board. Otherwise that board should work; you don't need the infinity stops if you are ground glass focusing.

Thanks, everyone. I believe I'm beginning to see what I have done. I can either get another lens that has the correct lens board, find the correct lens board or just use this lens as is not use the rangefinder.

Older thread, I know ...

just to shed some light on this issue and put some things straight in case someone stumbles over this thread looking for an answer ... Despite what was written here a while ago, the 65mm f7 lens was originally indeed mounted in a factory recessed board (not to be confused with some elusive aftermarket recesseds board that were sold a couple of decade ago or so the legend goes).

So, although this is not obvious at first glance when looking at pictures on the web, the original board of the 65mm is slightly recessed by 10 mm or so ... Horseman cleverly used these recessed boards of different measure not only for WA lenses but for several of their focal lengths, so two lenses of different flange focal lengths could share the same infinity stop (as color coded).

In the case of the 65mm f7 lens, the recessed board has the added benefit that it keeps the front standard away from the clamshell housing with the lens in infinity position, thus enabling full movements with that lens. If a 65mm f7 is mounted on a flat board, you will most probably not be able to apply full rise with the Horseman cameras, because the clamshell will get in the way. What I am writing here refers to the last generation "black wrinkle finish" boards from the VH/VHR era (I have no yet seen a 65mm f7 on one of the older hammertone finish boards).

BTW, you can also use the original recessed board/Seiko shutter combination of the 65mm to mount other brand 65mm and possibly also 75mm lenses. I have tested this for the Fujinon SW 65mm f8 (originally also sold in a Seiko shutter), which cannot be used with movements when mounted on a flat board. You have to be careful though as their are different versions of the 65mm f7 circulating with different size threads in the shutter housing. The Fujinon SW 65mm will remount correctly in the shutter of a late version Horseman 65mm f7, which is the version with symmetric front and rear cells (both cells about the same diameter).

I tried to find a recessed board to mount a Schneider SA 65mm, but couldn't find one. Ended up getting a Super ER 65mm with its factory recessed board. Turned out that it's a great lens; I don't think the Schneider would have been any better.
