Why m4/3 lenses are SO expensive ?

Wanted to add to my very nice 14mm 2.5 Panny something faster and longer like Panny 25mm 1.4 and checked out prices at amazon.co.uk and wow

Panasonic 25mm F1.4 £427.36

when , actually brighter Canon (as needs to illuminate bigger sensor with same amount of light) with bigger diameter glass inside costs so much less

Canon EF 50mm - f/1.4 USM £274.95

even Canon L beast With 3,5 times more optics and metals (200g against 705g) cost only just a fraction more

Canon EF 70-200mm f/4.0 L USM £475.00

is it R&D, for what we are paying so much ? or what ?
