Re: PESO" New Year's Day Walkaround

I'm not sure what we are talking about here. The out of focus branches 
are rendered somewhat transparent and diffuse. That's just good bokeh 
in my book. Shel reported purple fringe. I haven't seen it, although 
there is some color in the background branches.

although i see it on my long lenses sometimes too, i don't see it as 
often
on the FA* and A* ones. i find the bokeh on the FA 80-320/4.5-5.6
objectionable enough that i don't use it unless i literally have no 
other
choice. i'd rather pack the FA* 80-200/2.8 or the FA* 400/5.6 if i
possibly
can. it takes far more extreme circumstances for it to appear than 
with
the
cheaper lens. as far as i am concerned it is a combination of 
chromatic
aberration and flare.

I had the *istD set on center spot autofocus, so I fixed the focus on
the critter, then reframed the shot. I'm not sure that this phenomena
should be described as CA either. Every long lens I've ever used
produces some strange bokeh with extremely out of focus branches
against a bright sky. I don't find it objectionable. In fact, I find 
it
quite interesting.
