Well, here's my penny-worth. Anyone who has studied elementary physics
(weight, mass, work etc) will know about the effect of inertia and the
mechanism of conservation of energy where items of very unequal mass are
concerned.
This is what is in operation here.
A few weeks back I reported on what a close friend and knowledgeable
amateur photographer of some ability of some 35 years' standing said to me
when we discussed this topic. It was the era when Pentax produced one very
small SLR about the size and weight of an OM-1. My friend Dave had the
loan of one of these Pentaxes for a week or more, and ran about 20 rolls of
film through it. Not only did he have problems getting his fingers on the
necessary controls (they were too small, and being at that time engaged in
demandingly physical work he had strong, quite solid hands with thick
fingers), but most of the frames were so blurred that he threw away all of the
20 rolls. He then bought Minolta which he has stayed with since then.
Happily and with no regrets.
If there is vibration from one or more sources in a camera, and if, when
comparing the mass (weight) of the component causing the vibration with the
rest of the camera, it is relatively large, then all other things being equal
the
camera with the relatively smaller vibrating component will yield sharper
images.
The heavier body has more inertia, therefore the source of vibration will move
it less.
To use an automotive analogy, in case what I am saying is too abstruse,
imagine a Greyhound bus hit by a BMC mini cooper car. It probably wouldn't
move the Greyhound around too much. Imagine now the same bus impacted
at the same relative speeds by a Hummer. The Greyhound would be in bad
shape due to the greater size of the relatively larger moving component.
This is one reason why I have a winder attached to my OM4Ti. Since my
arms are now quite light, I figure that the extra mass of the winder will aid
in
IS when taking hand-held shots.
This matter is probably one of the reasons why the mirror is so small in the
E-1. Small mirror, less vibration.
Exacta cameras were also relatively heavy.
