My combination for this week will be the D7200 and AF-S Nikkor 35/1.8 ED. This is the FX version of the 35/1.8. I'll try to borrow a DX version and use for a week at a later date.
If anyone else wants to shoot a single lens with me for a week, feel free to post what you get in this thread.
Don't forget that the subject says one lens, so you can use your favourite zoom if you want to, it doesn't have to be a prime. The idea behind this exercise is to get in the habit of using our cameras. Remember that the best camera is the one you have with you and are familiar with.
