Try to shoot more and comment again. I'm the guy who once sold the
90/2 and made a lots of comments on the list about how the 100/2 is
better in resolution for normal distance at wide apertures and the
50/3.5 and 80/4 perform better for macro.
The 90/2 was back to me for around two years and I have gave it some
chances. All I have said is still valid, but I have to add - the color
of 90/2 is almost the best among them with the 50/3.5 come very close.
Both 100/2 and 80/4 are very sharp and high resolution with 80/4
higher in contrast too. But both lack something that 90/2 have
including the hard to measure 3-D look.
I would say every lens has its only merit and you need them all:
- the 100/2 is a lens for portrait (may need a softer if you subject
is over 20) landscape and group photos where you need the finest
details.
- the 50/3.5 is a general purpose lens for family shoots and for
flowers which you can get very close but not long enough for insect.
It is light so you won't mind carry it even you already have a 50/1.4
inside your camera bag.
- the 90/2 is very colorful, great for nature and artistic shots,
actually it is very sharp if you stop down to F4 or 5.6.
- the 80/4 is a dedicated macro lens for duplication, where you can't
afford any loss in resolution. It is also great for insect shots which
to be use on text book, it is extremely sharp.
