Tom, sorry about not being able to get back to you until now, I was in
Charlotte for the LHSA meeting and out of e-mail touch. I truly like the
24/2,8 ASPH and in spite of its finder ( still hanging on to the camera with
some help of gaffers tape) I find it better than the 21/2,8 regular. I
haven't had a chance to put the 21/2,8 ASPH through its paces yet and when I
do I will put it up against my 21 S-A. The flare problem was something that I
encountered with my 35/1,4 ASPH. I shot a sequence at a " car blessing"
ceremony in Tokyo in February and on three shots the image was partially or
totally flared out. The lens is now in Germany for service and I am eagerly
awaiting its return. The 24 ASPH so far has not shown any tendency to the
same flare, but I hope that my 35/1,4 was a fluke. The biggest problem is
that I live in Vancouver,BC where the sun is a rarety in the fall!! I feel
that the concave surface of the ASPH lenses could increase the risk of
bouncing light. It is not a condition one can create, I have shot straight
into the sun, no problem, but if the light hits at a certain angle ( about 11
a'clock angle ) it bounces or reflects from the bottom of the lens and
scatters across the surface. So far no problem with my 35/2 ASPH or the
24/2,8 ASPH. I am eagerly awaiting the sun to put the 21/2,8 ASPH to test.
