SL II Sensor Size increase?

No.

 

My explanation has nothing to do with any fixed industrial standards. I have no clue what you're talking about.

 

I'm mentioning LEICA's standards, the SL and S cameras.

 

The SL matches the standard size LEICA created. Others followed.

 

The S is another size LEICA created. It's not the same as ANY medium format or any other sensor or film size.

Whatever.

A larger sensor or film plate will require more glass area and therefore larger diameter.

Mirrorless can allow lens to be mounted closer to sensor and filmplate therefore accepting smaller diameter lenses.

Therefore micro4third cameras generally have more compact lenses due to smaller sensor size and mirrorless.

Can you see the relation???

Yes you were right but not entirely correct. A larger sensor size on SL will fit current SL lenses but cropped. For example SL can accept TL lenses but only 8mp cropped. So the entire current SL lenses will not "fully served" a larger SL sensor.

 

MFT allows compact lens because there is no need bigger glass to cover the small sensor, Therefore lens for smaller sensor system if fitted to bigger sensor it will take the smaller portion of it thus my explanation above.

Increasing the sensor size means engineering new lenses to take advantage of it while simultaneously angering all of the customers who just invested thousands in the current lenses as they'll suddenly be incapable of using the full capabilities of the camera.  Plus it would undercut the lenses on the product roadmap.  Plus it would undercut the S.  It's a bad idea from multiple angles.  So why would Leica do this?

I think Mjh has a point, it is about light incidence, that is why Leica seems to have smaller glass in front of the sensor vs Sony. To accommodate high incidence M lenses. The SL does pretty well with most of the M lenses which is not the case with Sony, so it seems that keeping the same glass over the sensor increasing the number of pixels keeping the same full frame size is something that should play well with lenses like the 50APO. Now one question is why Leica is building low incidence lenses for the SL that are much bigger?

 

As a matter of fact Olympus strives to build near telecentric lenses for the (Micro) FourThirds system and such lenses have large rear lenses. You want the light to hit the sensor at a small incident angle which obviously requires large rear lenses. Trust me: You don’t want small rear lenses.

Mirrorless doesn’t imply small/compact lenses. Actually telephoto lenses must be longer when the the flange distance is shorter. Only some wide-angle lenses can be smaller as mirrorless cameras with a short flange distance don’t need as many retrofocus lenses as SLRs do. Micro FourThirds lenses can be smaller than those for APS-C or 35 mm systems simply because the focal length for a given angle of view is shorter. Which also has its downsides of course.
