I've posted this before but it shows the 80/1.9's harsh bokeh quite well. This is with max tilt (IIRC) on a Mirex and wide open.

But then you're kidding, since you know the bokeh is harsh & only you like it.

Seriously, I'd be happy with the 80mm or the 150mm.

On APS-C the 80 would probably be better for intermediate work, but I'd be curious to see the MTF's for it versus the 150. The 80 has the advantage of f/1.9, a stop+ faster than the 150, and provided it carries on with Mamiya's reputation for still being sharp(est) wide open ...

Next logical question: By price-point & quality how does it compare with other 645 or Leica-R mounts, w/ the specular highlights?

IAC, I'm prone to doing long work, birds & butterflies ... I might save up for the Sekor 200mm f/2.8 A/APO

I found these data on various charts on the interwebs... check out the 150/2.8 A versus the 200/2.8 A...

Lens name, focal length, max aperture & lp/mm

Sekor C 80/2.8 78
Sekor C 80/1.9: 82 (non-N, non-A)

Sekor C 105-210/4.5 62 (ULD )

Sekor A 150/2.8: 134
Sekor C N 150/3.5: 102

Sekor C N 210/4 78
Sekor A 200/2.8: 171 (APO)

Sekor C N 300/5.6 80 (ULD )
