Some more info about the new Laowa lenses

The 7.5mm is tiny really ...

There has to be a gotcha somewhere... these lenses look (lack of AF notwithstanding) too good for the size and extreme specs. Something doesn't add up yet. Smile (just like both 16mm pancakes - from Sony and Samsung - having serious issues stemming from their tiny size and fast apertures).

The 15mm f2 lens is not a DSLR lens which sits a big distance (40+ mm) to the sensor, rather the flange distance is around 17mm.

That makes the lens easier/smaller to design than one for a DSLR, and explains the size, more or less. Wide angle is where mirrorless with smaller flange distances can have the advantage.

 

Why the 7.5mm f2 lens for MFT is that small? Because it is a 15mm f4 FF equivalent lens with a small aperture, and again it has the advantage of a 17mm or so flange distance rather than 40mm + for DSLR lenses.

 

The pancakes suffer mostly from design restrictions due to the limited room length wise (can't fit too many elements in there), and possibly less gifted designer in case of the Sony? This 7.5mm lens has a lot more length to play with, and with the small image circle the elements can comparatively less thick too, needing less space.

Now this lens makes sense in MFT world and with the extreme DOF when shooting landscape at f8 you can focus even without using the viewfinder assuming infinity and distances are correctly placed on the lens barrel

24/14 - anyone mentioned? 24 mm and f/14 (!)

Finally I know how to inspect a terminte mount. Just need some kind of ringlight....

WTF! I guess I wasn't the only one who thought that a decimal point was missing.

Doesn't look healthy if you ask me. Big Grin
