How do you dust off the inside of a Mamiya 7

<p>And how regularly do I have to do it?<br>

Also, how often should it receive a mechanical check up?</p>

<p>The easiest way of dusting out the interior of any camera without damage is to use compressed air in a can – well-known brands include Kenair and Dustoff. Don't point the nozzle directly at the glass - these cans use butane as an expellent. Frequency of cleaning depends on how much dust is present - could be once a day or more often if you are changing films on a windy beach. The same applies to a mechanical checkup – if the shutter is running accurately and all mechanical components are working correctly and without unusual noise, and the camera is used lightly in clean conditions, a checkup every few years will be fine. If the camera is used in filthy conditions, it will need checkingy much more often.</p>

<p>Perhaps a simple squeezable rubber bulb air blaster is a safe and useful solution for dust removal. Like cleaning a digital sensor, holding the camera with the open area downwards is probably good practice when using it.</p>

I'm not sure if these issues are "old wives stories" or true, but I have heard of some people having issues with the use of

cans of compressed air with sensitive camera components ...

 

1. That many brands of compressed air expel small amounts of a liquid that are deposited on surfaces.

2. That sensitive surfaces (i.e., coated surfaces and highly polished surfaces) can be damaged by particles blown across

them at high pressure by the compressed air out of a can.

 

I use Arthur's method (i.e., a rubber air blower - e.g., Giotto Rocket Blower).

<p>Thanks for all your responses. :) So basically I should use a rubber bulb air blaster, turn the open area downwards, and not point it directly at the glass?</p>
