Maybe it's just me? But a "Poser" focal length of 35mm just looks "off" to me, especially in closeups on the face. Having used an analogue SLR camera for the last 40 years, I just "feel" that the Poser FL values are far more closer to what I would get in my old (antique?) Pentax camera. So I still use the standard:

• 35 mm for landscape
• 55 mm for snapshots
• 85 mm for portraits
• 105(+) mm for zoom

and to my eye the resulting renders look realistic enough compared with what I would expect from a 35 mm film analogue camera.

"Eyephones" don't count - they live in their own twisted reality :P )
