Not doing the same job ( diagonal AOV, DOF /subject isolation and total light gathering ). A FF lens equivalent to the 12mm F/2 would be a 24mm F/4 . The m43 equivalent to a FF 24mm F/2.8 would be a 12mm F/1.4First lens I bought for my E-PL5 after the pancake kit zoom was the 12mm f/2 -- 130 grams and 43mm length. Nikon makes a 24mm f/2.8 -- 270 grams and 46mm length and a 24mm f/1.8 450 grams and 97mm length. FF lens tend to be bigger and heavier.Could you point to one FF lens that is larger than a m43 lens doing the same job ( diagonal AOV, DOF /subject isolation and total light gathering ).I have and use all three. Used least = FF. My FF cameras are too big and heavy -- the lenses are bigger and heavier and when I use a camera I'm most often walking and carrying it.I'm interested to know how many of you shoot with both M4/3 and FF or APSC.
That is the challenge what is considered as a "fast lens" in m43 is a modest FF equivalent and they are seen as lower end options . An example of honestly equivalent from the ( diagonal AOV, DOF /subject isolation and total light gathering ) . Obviolsy being a premium for the system lens the 12mm F/1.4 has much build quality etc

There is no AF 12mm F/0.9 to do the same job as FF 24mm F/1.8 lens
