Misinformation ?... Lack of information ?...
Confusion between Adapters With or Without Lens(es) inside ?
I use Adapters for Pentax
K(45.46), NiKon
F(46.5), Canon
Eos(44mm)... to Sony
E Mount (18mm)
=> I confirm -
1) there are Absolutely
NO LENSES inside these 3 Adapters !
-
2) A
Good Sharp Lens remains a Good Sharp Lens.

This MILC has to be built around a
Short backfocus Electronic Mount
... let's call it
PEM = Pentax Electronic Mount :
- the 1st Adapter to be the PEM to KAF4 = 100% Electronic Adapter !
- the 2nd Adapter to be the PEM to EOS = 100% Electronic Adapter !
- the 3rd Adapter to be the PEM to KAF3 with Aperture control lever ?
- the 4th Adapter to be the PEM to NiKon-F w/ Aperture control lever ?
...
Pentax only have to choose a Register Distance shorter than say ~41 mm for
K+
F+
Eos Compatibility
= Compatibility with Several Hundreds of
Good Sharp Lenses from Pentax+NiKon+Canon
The Compatibility with Sony
E Lens is Another Deal to Conclude with Sony
- inside the Deal for the FF Sensor with embedded AutoFocus...
If positive, requires a Register Distance of ~15mm
( it's not a problem, NX-mini=7.5mm )
If Direct Compatibility with Sony E Lenses (highly unlikely) Register Distance =18mm !

Are you
serious ? Despite Pentax stopped its SDP-UF Refractors...
K Astrams keep shooting !
... And you know what ?... You Always Need an Adapter for AstroPhotography !
Do you insinuate AstroPhotographer = ~sunday handyman~ ?
Except Misalignment, or Light Leaks, the Camera Body is of Zero influence on Optical Perfs !
During Exposure Time... Nothing is in the Light Path... from the Lens to the Sensor
Knowing this FF Sensor will be " Made by Sony "...
... does this mean your " Native Lenses " will be Sony
E Lenses ?
