Batteries for Linhof-compur shutters : LUSENET : Large format photography : One Thread

Does anybody know if these batteries are still produced, if not is there an alternative? Thanks!

This is not a Linhof shutter.

it is a compur Electronic shutter.

I haven't seen a battery for it in 15 years.

Prontor Werke might know what will work or if modifications are available.

Indeed the shutter is a compur but I have seen it very often on Linhof lenses , so I improperly assumed the Linhof-compur connection. However the battery in question is, a PX 21 and I had one in my hands, in working order yesterday , but the shop keeper kept it together with the similar lens in wich it was! It is a 4,5 battery , is there an alternative? By the way cannot find any e-address for Prontor werke.

Bob was right. Linhof never made any shutters. Your Linhof shutter was made by Compur (now a division within Carl Zeiss), just like those Linhof select lenses were made by Schneider. Px21 is a mercury battery, thus can not be sold in the US. You should be able to find it in Europe. If I remember correctly Minox and Rollei sell an adaptor to allow you to use more widely available watch batteries. Good luck,

As I said, I erroneously called Linhof-Compur a shutter which is produced by another brand namely Prontor-werk(I've found the e-address.....). I could be forgiven for being imprecise though, because the prontor shutters are the choice shutters for depiction on Linhof advertising matter. Unfortunately (or is it?), the enviromental legislation in Europe is even more stringent than the states and mercury isn't allowed in batteries too, recently though some articles appeared concerning viable alternatives offered by Japanese battery producers which could provide an alternative, I wonder if someone has a list of which product replaces which. Thanks anyway!

Sorry, Andrea. I did not read your second message carefully enough. Here's a place might help you:

Linhof certainly did make shutters, and they still do make a shutter.

Linhof originally made the leaf shutter that was sold by Valentin Linhof at the start of linhof 110 years ago.

When he patented his metal swing back design for the Technika he sold the design of his shutter to deckel.

Deckel made the Linhof shutter for many years until the shutter division became part of Zeiss at which time the Linhof/Deckel shutter was renamed the Compur shutter.

Today Linhof makes a high speed guilitine shutter with speeds to 1/1500 for the Aero tronica medium format linhof aerial camera.

Thanks for the education. Who said it's impossible to teach old dog new tricks?

Try calling Schneider (631)761-5000. I believe they can order this battery from their factory in Germany. It will be "quite" expensive but it can be gotten. Make sure you are sitting down when you call........

You can find generic versions of this battery that work perfectly in the shutter (I have one). The brand I found are called EXELL and have a part number A21PX. I buy them at a local camera store. Panasonic apparently makes a PX-21 battery as does RAYOVAC. So, you don't have to pay an arm and leg, maybe just an arm. Bob

Hello Andrea,

I designed specially for your Linhof-compur shutter a accu-Kit with recharger. It uses a 0,8V 1000mAh NIMh accumulator. It includes a DC- DC switcher to provide the necessary 4,5V for the shutter.

You will never need again a PX21 battery, because the accumulator is 1000 times rechargeable. The price of the kit is 50.-EUR. I think it is not too expensive, a new battery is about 22, if you can get a cheap one. The only handicap in the moment is , that I need for the specification the compur battery-housing to implement the accu and the dc-dc switcher. I planned in the future a kit, which looks like the PX21 and is also for other applications/cameras, where this type of battery is needed.
