What if the Tamron 17/3.5 lived on it? Central resolution on my copy, even wide open, is quite excellent.
Is that something you could live with (ignoring the f3.5) ?
If ~35mm is a FL you prefer, I'm sure results will be fine. I'm not familiar with that lens.
The Nex-5n with the touch screen is brilliant for MF lenses. Push anywhere on the lcd to magnify, focus, press shutter button to get back, exp.comp. simple with your right thumb. Everything is quick and easy - results are brilliant. I disliked the Nex in the beginning, but I've warmed to it. I understand what you're saying, but it really is a nice platform for alts.
I would likely use the distance scale and use the screen only for composition... I can't imagine touching a screen while taking a photo. But then I have an aversion to anything touch-screen. Damn, i am such an old man. Sorry!
