I'm going to buy in to NEX (after years of fence-sitting) with a limited purpose in mind. My main goal will be to use it for shooting portraits. I'm thinking I'll pick up the 50/1.8 e-mount lens and an adapter for my Zeiss Planar 50/1.7 and be pretty well set. If I "fall in love" with NEX I will look at the 6 or 7 or 9 and more lenses down the road. I'm coming from an E-M5 and some nice m4/3s glass, and not looking to recreate that as it was underutilized. What I'm aiming for is relatively low cost, limited purpose, but highly capable. So, does the 5N seem reasonable, or is there logic in going with the 5R or 6 or even the 7 right out of the shoot? Also wondering about banding issues on 5N LCD. Is that a serious issue? Thanks.
