i have a M6 0.85 TTL with summicron 50mm f2
, for me ,the optical quality, compactablility, reliability that lead me to but M6.
personally, i used for snapshot, and i think it's better to adapt with 1 lens only, and i choose the standard, i just don't want to change lens often ,but just focus on the composition and the alertness of the surroundings. some will use 35mm instead .
but let's enjoy the 1 body 1 lens set , and get used of this!!

論 user friendly , M7 既能AF,又能全機械操作,絕對佔優
但價錢方面就...
我的感覺是,除非真的有很多的預算
不然還不如買 G2,不比LEICA差

u mean M7 have autofocus function?
may be u are talking about aperture priority setting, right?
also, M7 is not fully mechanical , the shutter need battery to operate !!,  in case the battery run off, u just have 2 shutter to choose . but M6 TTL , it's fully mechanical , battery just for metering, u can take off the battery , with full range of shutter control.
i haven't got the g2, but i think is' s also electronic shutter, so not fully mechanical .
for fully mechanical, u can consider nikon FM2 for SLR, not Bressa series for RF

只要不要求"收藏級品相"...
a good user "M3+50" or "M2+35" 都比一台狀況普通的二手M6便宜...
M3有50,90,135框線...M2有35,50,90框線...
隨便選一台(機械功能正常ㄉ)都能滿足一輩子...
