Lens board for Busch Pressman D

Postby +rex » 11 Apr 2015, 00:43

Hello,

I'm a late entrant into the field of large format photography. I have picked a Busch Pressman D as my first camera only to realise that the seller pulled a fast one and the shutter speeds are way off (unintended pun). I have been contemplating a longer focus for still life and portraits and was wondering if there is any place in Melbourne that would make custom lens boards for a Busch Pressman D. I have come to realise that it is extremely rare to find lens boards for this camera.

I appreciate any leads in the matter.

Hi rex, welcome to the forum. Before you go the way of having boards made, I'd suggest the Large Format Photography forum in the US, a group large enough that you might find used boards there. You have to be a member for one month before you can advertise in the classifieds, or alternatively I could advertise there for you. As to makers in Melbourne, I can't help you. I make my own boards and might be able to make one for your camera, but I'd need to see it first, of course. I'm in NE Victoria.

Hi Barry,

Thank you for responding. I find the latter idea more appealing than having to search and import from the US. However, I say in the South East Suburbs of Melbourne, so we'll need to find a way around it. Would you be travelling to the CBD any time?

Thanks,
-Ranjit

No Ranjit, I travel to Melbourne as little as possible ! You would have to come to me, and bring a few small samples of aluminium sheet that we could work with - offcuts from an aluminium supplier would do - then we could go to work. I am strictly a DIY type and I make do with what I have. I don't know the specifics of the Busch but have enough confidence to work it out as I go. I'm happy to help you if I can, but I still think you could find used panels via the LF photography website I mentioned. Try: http://www.largeformatphotography.info/forum/forum.php quite a few people there seem to have Pressmans

Ranjit,

Can you post a couple of photos of the board?

I might be able to help.

Lachlan.

Hi Lachlan, Barry,

Attached are images of the Busch Pressman Lens board. These pictures are from the LF forum. I'll try and post images of my camera soon.
Notice the little notch to the top of the board? That design seems to be specific to the Busch Pressman. The hole in the front of the board seems to be something that the lens board designer made himself, I don't have that on my camera.
Also, there is a 3D rendering of the lensboard at this site: https://www.tinkercad.com/things/7YAvnYx0Lzw-busch-pressman-4x5-lensboard-prototype
(although i fear the 3D rendering might not be for a copal no 1 lens).

Barry,

I'll look up the LF forum. But I may just prepare myself for that long drive.

(Roughly) how thick are they?

I can probably cobble something for you to test. Having one in my hands would help.

Hi Lachlan,

Attached are the images of my lens board. I measured the front sheet of the Lensboard assembly to be 1.48mm. The front and back sheets measured a combined thickness of 3.6mm (making the rear sheet 2.12mm thick). The notch that has the screw hole to retain the lensboard in the camera measured at a width of 18.02mm.
The width of the square board was 75.5mm.

Let me know your thoughts.

Regards,
-Ranjit

Hi Lachlan,

Have you had time to think about the lens board? Do you think it is feasible?

Thanks,
-Ranjit
