LX100 is poor in useability such as:
– No ND filer – no good for video
– Fixed LCD – not for high/low angle shoot
– No real auto lens cap – slows down the flow
– No built in flash
– LX100 has noticeable lens flare
When you rescale them both to the same size, both has more less the same IQ.
Yes, LX100 has faster lens while you zoom in half way, but it may be not enough to justify the size.
BTW, I like PASM dial better b/c PASM dial has more options than just PASM, and it is easier to change the mode as LX100 is not a “old” Leica M, but a P&S.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
