>>3453246>and it's a design constraint for lensAs evidenced by the three massive lenses above, it's actually just big enough to fit all of those optics.
I could turn the argument upside down and argue RF-mount and Z-mount are constrainted in the sense that they will never have a lens as compact as the 35mm F2,8.
Their diameter is just excessively large, so their pancakes will be unnecessarily large.
the Sony mount was actually fully optimized for compactness all along.
>>3453358>If that was it then someone else would have produced the lenses Canon is announcing and producing now.No, they are 3rd party, they know their lenses must be cheap.
3rd parties usually don't get away with asking 3000 dollars for a 50mm lens.
My simple basis is correct.
