Yes, the reviewer is a Leica fan, but not a fanboy.This reviewer is obviously a Leica fan.
As a long time Leica user I find it an interesting camera but a poor value. To many bigger pixels on offer for less money.
I resisted Leica digital for a long time. I finally concluded that all the "value seeking" was costing me more money in the long run as I hopped around from one great value to the next that were large and bulky. After new kit enthusiasm waned, the kit was left behind in the car or the house in favor of a pocket cam, like a GRIII. Eventually it occurred to me that despite wanting the ultimate in image quality, the reality was that the size (weight and bulk) of the gear was getting in the way of me making the photographs I want. It finally dawned on me that size does matter, and image quality too and the Leica M and compatible lenses ticks those boxes and goes with me almost everywhere. I learned the most expensive camera is the one you leave in the car. The M system is not inexpensive but when coupled with some superb Voigtlander lenses, the value proposition improves significantly. I happen to have some Leica lenses also, one of my favorites I've owned for 35 years.
