Nex 6 lenses, need advice

I have the Nex6 and the 16-50 the clear zoom feature is great and even viewed on 55 inch tv looked great. I tried the orginal Sony 18-200 and compared it to the Tamron 18-200. What I thought was that they were very close in everything. The Sony is said to have

a better stabilization but when put on the Nex6 did not give much room for fingers. I decided on the Tamron and  since I got it I have shot some great pictures and video at 6400 iso. Another thought is to look into the LA-EA2 autofocus adapter for putting A m

ount lenes on your Nex6 it gives another option to your Nex6. I have it and it works great
