Just bouncing this thread with a question.
I'm slightly confused on the variety of uses of a dedicated f2.8 lens. The one in particular that I am looking at is the beaut little Olympus 12-40mm PRO lens (
http://slrgear.com/reviews/showproduct.php?product=1641) for use with the Olympus OM-D E-M5 II MICRO 4/3rds camera. I know a the basics of using an SLR, and for years used a Nikon F90X before the world went digital, but I've never used a constant aperture lens before.
I want to use the lens for most situations really, but particularly for landscapes and people shots. I know it is a nice sharp lens and should give decent results with bokeh and low light situations but can these lenses be used when I want a large depth of field too?
Any thoughts?
