I've been using Sony cameras for the last 5 years (NEX3,5,6, A65 and A7). I just got the A7 two months ago and thought I had reached the top of the GAS mountain. Then the epiphany hit ... while I had great camera bodies, I had very few AF lens choices and the ones available were relatively overpriced and oversized. I had not kept up with the m43 advances over the five years and was amazed by the system's growth in lenses and sensor quality. Long story short, in a couple of weeks, I assembled a kit (all second hand and at great prices) as follows: e-m1, native 9-18mm, 17mm 1.8, and 45mm 1.8. via MMF-3 adapter 35mm f3.5 macro and 14-54mm 2.8-3.5 and FL600R. I finally have the lenses I need to cover all of my shooting needs. I look forward to learning and sharing with members of this forum. Cheers!
