Camera shake phenomena

Deeper consideration and several experiments enlarging images on LCD have proved the fact that resolution and sharpness of a picture that is often talk about have most to do with the camera hand holding condition and the shutter speed, especially with the weight and balance of the equipment. Above 1/30 and heavier balanced one have advantages to avoid inconvenient camera shake. Even with critical Balsam peeling defect in lens constructive element, Leitz Elmarit-R 135/2,8 lens plays extraordinary excellent performance when used actually, I don't know why it is so better than others?
The trick has solved after the experiment and comparison on the lens weight. Heavier lens body wight, 730 gr without filter plays a good part as a stabilizer preventing hand holding camera shake considerably. Minolta once manufactured heavier XE model while the silver salt film period, sister product for Lietz company was R3 with automatic exposure capability, but the model concept was changed into lighter and smaller ones inviting the same concept  also on lens constructions as MD models.
I want to ask to myself, the lighter and the smaller are the better? Now I have realized again the importance of the former concept even in advanced Digital age again, because basically I don't believe in some sophisticated inventions, lens internal optical direction adjuster nor image sensor anti-shaking construction, saying to myself that the camera body or lens body should be fixed on the solid and stable tripod in any situation and at any location following an old principle for any photographers.
