Swifty, you have to remember that Panny is also a sensor manufacturer. So anything can happen. How far back is the current Panny S1? If it's forward enough (like the 4/3) they could add an adapter for the mft to use the FF lenses but not the other way around. I doubt the mft light circle is big enough for the FF sensor.
P.S. Just read this
Nikon Guy going mirrorless
Where do you think he is moving to?
Hi Blu By-U, unfortunately Panasonic has divested their sensor business already. Their remaining JV with TowerJazz (TPSCo) has been sold off although I can't remember whether the deal is completed though.
The L-mount's flange back distance is longer than the m43 mount by 0.75mm, but the throat diameter is significantly larger so the entire m43 lens mount can fit inside the L-mount. It's not an easy adapter to make but a m43 lens to L-mount adapter is at least theoretically possible.
It'd actually be impossible the other way around, meaning an L-mount lens to m43 mount adapter because a 0.75mm thickness adapter on the outside would just be impossible.
M43 lenses are only guaranteed up to the m43 image circle (some may be larger but don't count on it). When used on a larger sensor such as APS-C or FF you're certain to get (severe) vignetting if you're using the whole sensor. The point of multiaspect ratio sensors is you crop in from an oversized sensor in any ratio up to whatever the m43 image circle allows. If you're not familiar with the concept have a look at cameras such as the GH2.
Normally when we want a different aspect ratio, we'd have to crop in from the m43 sensor so we'd use an even smaller sensor area for our capture. When cropping in from a larger sensor, you'd maintain the maximum image diagonal of 21.6mm in any aspect ratio.
Eg. If you use an APS-C sensor, you can crop any landscape ratio up to 1:1 and still maximise the 21.6mm diameter of the m43 circle.
If you use a FF, you can crop any landscape or portrait ratio meaning there'd be no need to turn the camera at all.
I agree you wouldn't use a FF sensor just for this ability, but it has been suggested it's easier and cheaper to source APS-C sensors than m43 sensors so this additional ability to crop to any ratio seems like good added bonus.
Yea I read somewhere that Matt Granger has sold off his Nikon DSLR gear. TBH I rarely watch youtubers so I really wouldn't know but their business model is somewhat tied to generating drama so ppl would watch their channels. It could be any of Canikony I think, maybe Canon just cos they have a bit of momentum atm and are in a rapid growth stage with probably lots of gear to review in the medium term vs a more matured Sony system and a slower Nikon system.
