Pentax-110 lenses for BMPCC / micro four thirds

What do filmmakers (especially independent ones) look for ? Lenses.
I stumbled across some lenses for the Pentax-110 which seem to address many of the requirements usually searched, which are the sensor coverage of the Blackmagic Pocket (and GH4 likely), being available (not unobtainium) and of course reasonable priced (under 200 USD for a -full- kit of lenses). Lastly you need a M43 to Pentax-110 Adapter, which is also widely available.

Speaking of the lenses, officially, there are 6 different lenses available, one of them very rare:

The Pan Focus lens is nearly “unobtainium” — but the others, and it’s nice to work with them; we’ll provide you examples from both cameras in the short term.

Update (14/11): I was able to acquire the Pan Focus. So i’ll also update footage later on

Focus charts will be created as well in the next days, so keep an eye on this page.

Useability

I was quite surprised to notice, even with fixed aperture of f/2.8 those lenses can be used during night shoots, as well as bright daylight. Unfortunately, as outlined in tests from other bloggers, it has a Spherical aberration leading to corner softness which does extend into the frame and it does not have a Digraphragm. My thoughts on this are that those lenses are vintage-type and provide those “special” cinematic look i was looking for.

Factsheets

Those will be provided as soon as i was able to shoot the focus charts and the sample footage on GH4 and BMPCC.
