This was the first camera ever given to me to use. I used it for 1 year and put it away. I found it last year and the batteries are missing, and so is the rewind arm. What kind of batteries are required? Does anyone know the Minolta part number for the rewind arm? or even a place to get a replacement rewind arm?
According to online sources, this camera can take 4 second long exposures. Would anyone know how to do that? |

Hi 'Minoltakid',
The Hi-Matic F takes two 640 type, 3V Mercury batteries. Mercury batteries have been banned a few years ago but, replacements are available. A 30 second Google search comes up with a quick answer, including instructions on how to build a battery adapter:

I am quite sure that if you spend less than 2 minutes 'googling', you'll find even more information. As to the "rewind arm" - do you mean the shutter cocking lever or the film rewind crank? Both can be found relatively easily - eBay is often full of dead Hi-Matic F's and many can be found in thrift stores, garage sales, flea markets etc., often for less than $5.00.
As to the 4 second exposures - the Hi-Matic F is a fully automatic camera with a programmed shutter/aperture. No input from the user (apart from focusing and setting the film speed) is necessary. If the light level is low enough and conditions dictate a 4 second exposure, that is what the camera will deliver.
Best,

The correct voltage of the old PX 640 was 1.35 volts, a pair of this type of battery was widely used in the vintage auto cameras (Petris, Ricohs, the Sensoret, etc. The newer replacement types also have 1.5 V, similar to the 625 types. |

#675 hearing aid batteries are 1.4 volt, (zinc/air)are usually about $1 each and sold in most pharmacies. They are smaller than the original mercury batteries and will require some shimming to fit and make contact properly. |
