Bests & Worsts Reviews from Amazon

Having pre-ordered and purchased this as an upgrade to a NEX-6, here are some initial impressions: First off, the biggest improvement by far is the autofocus. They're not kidding - it is fast. DSLR fast. Even in low light situations that would leave the leave the NEX hopelessly hunting for focus, it can lock on. Focus seems very accurate as well. Other enhancements: + More ISO Choices: The NEX-6 ISO settings were in 1-stop increments - 100/200/400/800/etc. The A6000 offers 1/3-stop increments: 100/125/160/200/etc. I'm sure this will come in handy. In addition, it offers multi-frame NR as an additional option when selecting auto-ISO (though this option is not available when shooting in RAW/JPG mode) + Better menu system: It is now much easier to use, and resembles the menu system of the RX100. I was able to get the camera set to my liking in a fraction of the time that it would have taken with the NEX-6, even today after using it for over a year and nearly 10,000 shots. + Better low-light performance: Shooting back-to-back with the NEX-6, the A6000 yields much cleaner JPG output at a given ISO. I haven't yet had a chance to look at RAW. + Burst mode: WOW. Continuous Shooting drive mode now offers three modes: lo/mid/hi. Speed priority is no longer there, I presume because of the much faster image processor and autofocus renders it unnecessary. On "Lo" it feels about the same as the NEX. On "Hi" it is like a chain gun. + The viewfinder: Yes, I think it is an upgrade. I could not discern any lower resolution, but it definitely is faster on the refresh and better in low light. + Auto-ISO: As was pointed out by a helpful commenter, it IS now possible to change the default range limits that auto-ISO uses. This is a much-needed upgrade, and will make this function usable for me now. Cons: - As another reviewer pointed out, the (legacy lens) manual-focus assist zoom button has vanished. When using a legacy MF lens, they were a big help. However, the C2 button can be repurposed for that function via the menus, and although it doesn't work 100% as before, it does the job. Overall, I'd give this camera six stars at this point if I could.
