Re: Leica 100mm APO macro - hard to beat


Agree ... there is a relationship between mass & steadiness, say on a tripod.

But when you are discussing muscle strength and weight (mass, gravity & angles) ... not to mention fatigue of working all day doing a shoot (as Thrice had been) vs. doing a single shot set-up for 10-20 minutes, these things matter and it\'s not as simple as it might otherwise appear ... wind, footing, terrain, shooting angle, etc. all come into play.

As for adding mass, that comes into play with dampening movement vibrations. In an SLR, you have the movement of the mirror, which causes significantly more vibration than the shutter. In your bridge / P & S (also rangefinders), there is no mirror (electronic viewfinder vs. parallax vs. optical viewfinder considerations), therefore no slap, therfore MUCH LESS vibration, therefore less need for dampening mass. So you see, it is not as simple as it looks on the surface.

Muscle stability vs. vibration dampening ... two very different animals that yield somewhat similar effects. Again, the P&S is less prone to such issues ... again, too many variables to be a meritable comp.
