Subject: R 80 Summilux/R lens line up

Folks,

I just got done testing the R 80 f1.4 along with my R 90 f2.8 in the
close-up range.
All the shots ( both lenses ) were taken at f2.8; using my r8s. Slide film
was Kodak's
E100SW; heavily bracketed in a variety of indirect light.

As you may recall, I put the 80 f1.4 up against the 90 f2 in Kennebunkport;
comparing the two lenses at f2 apertures in the close up range. I was quite
surprised how much better the 80f1.4 performed ( sharpness, in particular 
)
in the close up range.

In any case, I put the slides up in two rows on a light table ( picking the
crop of the litter ); my wife, picked out in each & every case, slides from
the 80 f1.4 as being sharper than those from the 90 f2.8. 

I would have gathered, from various sources, that the 90 f2.8 would have
performed better in the close-up range; however, my 80 f1.4 really does
very well in the close up range at f2 & f2.8 apertures. Quite a pleasant
surprise!

All of this is in an effort to determine what lenses could be traded off to
fill some gaps that I've got in my R line up. I'd really like to get the 19
f2.8 & am seriously considering trading in my R 24 f2.8 & R 90 f2.8 for it.
