I'm having quite a little dilemma amongst myself. I have enough money saved to buy either a new lens like a used 12-40 2.8 or buy a used Fuji XE-2 with an 18-55mm lens combo. I've been reading a lot of threads. Some say having a larger APS-C sensor makes a lot of difference in low light and the fuji system can shoot sharper pictures. Others say M4/3 is on par with APS-C sensor and the difference is minor. Do I keep investing in M4/3 or do I try a new camera and possibly move to a new system. Here are some low light shots I took recently in Boston, with my beloved 17mm 1.8 and my 25mm 0.95. It is a little grainy when looked on a larger screen. If anyone has both systems and can chime in.
