Dunno, is the Irix 150/2.8 mentioned somewhere here? Can I suggest, not to open up multiple threads for one item, like you did with the Zeiss ZX and a couple of other products? I find it very hard to follow or to make find out who said what where.

What has the Tokina (Sony E) to do with Irix (DSLR)?

Only the "100" in the FL

100 is not the same as 150, either.

Macro then
