Well that's an odd thing to claim as some kind of factoid. Why then does
this inexpensive 20x f/2.8 P&S zoom lens easily beat the pants off a 3x
DSLR zoom lens? (The same lens now available on several Canon Powershot
models.)

I guess there must be a design-slump in the 10X range. Yeah, that must be
it.

Leica-branded Panasonic super-zoom lenses are excellent at that zoom
range and more, on par with dSLR primes in terms of resolution.

So, the tests of the Panasonic 14-150mm and the Olympus 14-150mm look the
same to you? Also, the Panasonic is optimized for video, read the whole
test.
