One of my Brothers in law dropped by yesterday, and over a cuppa I was showing off the new toy. Sitting at the table opposite me was his future wife and bang, I couldn't resist a candid snap.
Shown as a portrait crop out of a landscape shot, it still needs a bit off the top to get the eyes into the right position in the frame, taken at the wrong focal length for a potrait etc etc, however it printed out well on A4 and looks OK from the correct viewing distance.
It looks good for a candid, although as you mention, a longer lens would de-emphasise some features a little.
Just wondering what you used in the way of lighting? - it looks like a touch of fill-flash, but the catchlights appear to be offset, so I'm wondering if they're window reflections instead? (or both?)
As I said Colin, everything was wrong. Sitting under a Flouro light, one window about 2M to her right and another about 4M to her left. I prefer to do portraits at effective 100-105mm, with soft lighting.
