優點:
1) dual dial-wheel deliver the control of DSLR.
2) F2.4 - 1step bigger than most common F2.8 of existing compact dc; a F2.8 DSLR len cost double (at less) to a F3.5 one.
3) F9 + iso 64 + build-in ND2 + long time exposure (180s max) = wash out people in street; most compact dc can not.
4) compare with LX1; color is natural and better corner to corner sharpness.
缺點:
1) Ricoh can do a better GR; we need to wait for the improved version.
2) the rear wheel can not select option in ADJ menu but call up ADJ menu; less convenience.
3) left hand index finger frequenctly push down the flash light.
