Dark times ahead ... for your wallet
Hey ... it's a matter of interest, that's all. I've spent some serious hours playing with all sorts of configurations and levels of light to appreciate the lower-end stuff. Of course, anyone can appreciate the expensive stuff. The challenge is certainly reduced, judging from that CZ 135mm f/1.8 I picked up.
Good luck in locating a SP AF 90mm f/2.8 Di 1:1 MACRO
I'll see what I can find around here, but you are right ... it doesn't look good. Appears like SONY is really SLAMMING that door to alternatives to their high-end lens line. The days of cheap Minolta and TAMRON alternatives are over. SONY has a controlling interest in TAMRON ... and that pipe is, for all practical purposes, shut off. Oh sure, they will still pump out lenses for Canon and Nikon ... to drain the competing OEM lens resources, but that won't be happening to SONY from here on out.
