I own an EM1 and I'm primarily a black & white jpeg street photographer. I'm tempted to treat myself to a Pen F, but I have a few questions. I'm confused about the Creative Dial on the front of the camera. According to the manual, when I select something on the Creative Dial, I can then use the front and rear dials to select options for that Creative Dial setting. But if I'm in Aperture priority mode, aren't the front and rear dials used to select Aperture? It seems confusing. Let's say I choose Monochrome 1 from the creative dial and change my aperture to 2.8... but then I decide to use Monochrome 2 instead. How do I get the front dial (or is it the rear dial?) to let me change the setting of the selected Creative Dial function? In other words, how do I chance from Monochrome 1 to Monochrome 2 when the front & rear dials are set to change the aperture? ALSO: In Aperture Priority mode on my EM1, the front dial selects Exposure Compensation and the rear dial selects the Aperture value. Since the Pen F has a dedicated dial for Exposure Compensation... what does the other dial do when shooting in Aperture Priority mode? One last question: How's the EVF on the Pen F for someone who wears glasses, especially in comparison to the EVF on an EM1?
