Are you sure about the f0.8, Jan? Doesn't the Baveyes adapter limit the focal
ratio "gain" with very wide aperture lenses?
It's alluded to in the DPR "First Impressions " report on the Metabnoes adapter
(the two paragraphs immediately before the Summary):
https://www.dpreview.com/articles/2667195592/first-impressions-metabones-speed-booster
It is also specified in the White Paper announcing the original Speed Booster,
noting the maximum input aperture: f/1.26 and maximum output aperture: f/0.90:

That may indeed be part of what we are both missing in the Metabones Ultra.

By all means, get a decent focal reducer if you’re going to play with legacy
lenses! But they’re ~30 times more expensive than simple adapters, so you’ll
want to get the ONE for the majority of lenses you think you’ll use. I got a
truly crappy one for $60, returned it to Shamazon (who never refunded me!), and
got a Kipon Baveyes ($150), which I’ve been happy with, while wondering what
I’m missing by not having a Metabones Ultra ($450).
Another of my favourites is my “bokeh monster” combo of OM 55/1.2 with the
Kipon Baveyes, yielding a 39mm f0.8 combo. It won’t win any contrast or
sharpness awards, but you can fix the contrast in post, and the sharpness is,
shall we say, part of its charm. :-)
