Hi Jeff, I have a 645Z and faced similar questions to you. You may find
what I have written about the camera and some of the lenses useful. There are some full resolution full width image strips there for you to look at.
Considering your interest in 75mm to 200, I'd consider the 75mm an absolute must. It performs beautifully and at 215g and modest price, its a no brainer.
I have a 80-160mm A which is very good, but not quite perfect. It seems there is sample variation out there, but all my used A lenses perform beautifully.
The 120mm macro is a very popular and strong performer, although I find mine needs more stopping down for corner to corner sharp infinity work than is ideal for my uses, but it does get there by f11 (and wider open when closer in).
The 150mm A is cheap as chips and very good by all accounts.
My FA 200 has not been fully tested, but seems very good indeed.
The 150mm to 300 looks very interesting, stopped down to landscape apertures.
Bottom line is that lenses are so affordable and readily available that there is relatively little at stake. If you get a dud, you can return and try again.
I'm thrilled with my 645Z purchase and if you do decide to venture wider, the 28-45mm is astonishing.
