[Leica] Nikon forum advice (OT!)

[mark at rabinergroup.com (Mark Rabiner)]

Lets not forget 24 to 120 is a 5X zoom ratio.
For many discerning users that's way higher than any other lens they own or
use.
Traditionally such do-all "idiot lenes" are spurned by serious shooters and
pros. I do think that at least that the current version of this optic has
crossed over. It is used by discerning people.
No its not going to be used for architectural shots and interiors but it is
used by events photographers and I'm sure photojournalists.

But its not the kind of thing where you're looking at the extreme corners
wide open or stopped down only one and worrying about it.
24mm
28mm
35mm
50mm
85mm
105mm
120mm
That's a lot of focal lengths, Seven, 7, to all be good at.
Normally I'd be picking about a zoom with a much more on conservative ratio.
Leica made a  28 mm - 70 mm - f/3.5-4.5
What's that zoom ration I don't know how to do the math?
It covers not seven but four of these focal lenghts.
I bet it stands up to some serious corner pixel peeping maybe even wide
open.
