So, you want to shoot at FL of 35-40mm. Good low light performance. Fun camera to use. Mostly casual snaps of people in less than ideal lighting. You also want high value (yeah, that means "cheap". What do you choose? I have three contenders in mind: The venerable GF1 + 20/1.7 combo. $325 used. Not great in low light, especially vs newer tech, but a pairing that always seemed to make me happy (both times I owned it). Not sure if nostalgia makes me believe the IQ is better than it actually was though. Canon EOS-M + 22/2. $300 used, though they occasionally pop up new for less than that. Great IQ, especially considering the price. Opposite of GF1 for me, in that I did not enjoy my brief ownership experience. Fuji X100. Always back to the X100 for me. $500 used. The clear winner in my mind in terms of output and user experience, but $500 slides to the north end of "value" category for me. What do you all think? Which would you choose and why? Other ideas are welcome, but consider the $500 price point the absolute max. Thanks.
