I had an early Lumix FT L1 that I loved. My first digital camera as such to
tell the truth. The Vario-Elmarit that came with it had such an efficient OIS
that I never ever even noticed what others call shutter-shock. I regularly shot
at 1/8 sec hand-held, and it was sharp.
That may be one of the reasons Pany didn’t bother.
My later cameras of quite a few other brands sometimes caused me trouble with
that, but so rarely ...
