Hello,
I just bought a minty Minolta Hi-Matic 7s. All is working fine, but there is a little play between the lens barrel and the housing. Is this normal or something to be concerned about? Is there a safe and easy way to cure this problem?
And another question on the use of the camera: How sensitive the light meter is to wrong battery voltage - should I expect serious underexposure with 1.5 V battery. |

It is normal. No way to cure the problem that I know of.
The voltage of a 1.5V battery varies during it's lifetime so you can not just compensate for underexposure. |

I haven't had a Hi-Matic 7s, but in other similar RF cameras the lens/shutter assembly is attached to a panel that as attached to the front of the camera with 4 screws - either just under the leatherette or hidden behind panels under the leatherette. Often these screws work loose and cause a slight wobble in the whole lens/shutter assembly.
A 1.4v #675 zinc/air hearing aid battery is the cheapest/easiest way to accurate metering. A silver cell in a CRIS adapter would be my second choice. |

The Hi-Matic cameras are notorious for having a wobble in the lens. First, check the screws that Rick mentioned. More often the problem is internal to the lens. There are screws that hold the focus helical together and they can wear or work loose. Also, there needs to be grease in the helical to dampen the movement. If the grease is dried out or migrates out then the helical wobbles.
Unfortunately you have to completely disassemble the lens to fix the problem and that is complex on that camera. If it isn't much of a wobble, I suggest you just shoot at small apertures and live with it.  |

Thanks for the info. Since most of the wobble seems to be located between the camera body and the lens barrel, I'll take a look at the screws Rick mentioned first. |
