Come on, I though you guys knew me by know...
Light intensity stays the same, yes, but depth of field of a 40mm f/
1.4 on Micro4/3 is
the same as 80mm f/2.8 on full frame, or 150mm f/5.6 on my Mamiya, or
300mm f/11 on
my Linhof.
No way will an image made with a 40/1.4 on Micro4/3 look the same as
an image made
with an 80/1.4 on 35mm. Not only will DOF be much, much deeper, the
40mm lens would
have to resolve twice as well as the 80/1.4 lens. That's not very
likely, unless you are
putting a Leica Summilux 35mm f/1.4 ASPH on your Micro4/3.
When it comes to portrait lenses, shallow DOF is everything :-)
