A6000 worthy upgrade from NEX-6?

[Otispunkmeyer]

Mulling over a camera update. Not really anything wrong with my NEX-6, I like the form factor. But its noise performance isn't brilliant and I have come to absolutely detest sony's old menu system.

So is the A6000 a worth while upgrade? Don't really care for the additional MP, or the burst rate, but better AF and noise performance would be nice and of course, a new menu system.

Also, has anyone tried the E-mount 16-70 mm F4 Carl Zeiss? Is it anygood?

I have one as a stop gap until I get my hands on owed money to buy a full system, and like it, though hamstrung a bit by having to download images to an iPad as I wait (for accountancy/tax reasons) for a proper computer next month.

Noise doesn't seem bad even at ISO I'd not have dreamt of with film, though I doubt I've seen the best outbid the files given import cockups and not having 'proper' software. I have fallen foul of sensor dust in underexposed/dark images on occasion, my fault I guess.

I like it a lot more than the RX100 I had, but pocketability isn't an issue for me.

I've got used to the menus pretty quickly and like the programmable buttons, which I use for ISO and exposure compensation. The viewfinder isn't bad, but I find the rear screen useless if the day is bright, like most I've seen, or this iPad.

The standard cheap zoom focuses like lightening and seems accurate, but feels very 'slight'. I use it most with the Samsung 50mm f1.4 Art lens or Leica 90mm and 180mm lenses with Novoflex and Metabones adapters. I'm used to manual focus and generally prefer it and the focus aid is good.
