I don't know why you'd buy the very expensive 12-40/2.8 to do landscape
photography. You'll never have need for that large aperture and the 12-50 is
a very fine lens which also offers a macro mode. Maybe the 12-40 will offer
better test results in edge resolution, chroma and vignetting but I don't know
nor do I know if it would be significant to the end photo. I agree that there
is likely no point to the 12-40/2.8.
And Moose has an E-M5 and some Pens but not an E-M1. The E-M1 and E-M5 have
the same sensor.
That's not true. It is true, as far as I can discern, that all the 16 MP sensor
Olys so far give the same practical image quality for this sort of landscape
work. (E-M5, E-M1, E-M10, E-P5, E-PL5, E-PL6, E-PL7, E-PM2) HOWEVER, the E-M1
is unique in that its sensor includes special on-chip sensors for phase defect
AF. This matters not a bit for you or me, but may make a huge difference for
those with 4/3 lenses. This is definitely true. I have both the E-M5 & E-M1
and the sensor is verydifferent. I have several 4/3 lenses (11-22mm my
favorite) and the focusingon the E-M1 is very nearly as fast as the m43 lenses.
Especially noticeablewith my 4/3 70-300mm lens. Mike, your photo of Yellow
Aster Butte is great, it brings back some greatmemories. I led a climb of
Tomyhoi (Mountaineers) back in the '70s, it wasalso in the fall, Yellow Aster
Meadows was a great place to camp. The viewof Mt. Baker was stunning. I've got
some great slides from my OM-1. larry
