I have EYE-AF programmed to the focus-stop button, but wasn't able to use it for this quick grab shot. My purpose was not a model shot, but a quick test of the sharpness of this lens at f1.4, and the lens passed the test. I bought this lens for its shallow depth of field so I am aware and quite capable of using it to my advantage. These were just first test shots, while walking my dog. Yes I made them with one hand (no extra hand to hit eye-af, which yes can be programmed to the AEL button for one-handed activation) while holding my eager and pulling new 62 pound dog Oscar at the end of his leash with my other hand. I like my Eye-Af programmed to the lens focus stop button. I love how you wish to school an award-winning pro of over 40 years how and when to use shallow or extended depth of field . LOL

Every semester and every course I have taught depth-of-field to hundreds of my university photography students over the years. I excuse you, you just didn't know the circumstances of my one-handed use here. The camera grabbed face detect, but I had no extra finger or hand to hit Eye-AF. Wasn't worth losing my eager new dog just to get eye-af on a test grab shot, a feature which I have used countless thousands of times on my A6500, A7RII, A7RIII and A7III for my professional and personal work since I switched to Sony mirrorless back in January 2017.

I used this camera for about 6 months before switching to the A7R3. Image quality, focusing speed and accuracy are respectable. The physical size is a little too small for even small hands. The controls are not ergonomically placed and easily confused, although very programable. The menu will take time to learn. Its a good camera but has its quibbles. It does NOT have IBIS which is a godsend when using unstablized lenses and to me is worth the extra expense.

The E mount lenses are good and contrary to what some think, not necessarily expensive. They confuse E with EF (FF) lenses which can be expensive but have excellent build and image quality. EF can be used on the A6300 but some will be awkward due to size and weight.

Be aware that the open box camera was returned for a reason, which may not be readily apparent. You would be taking a risk which in my opinion is justified if it were a great deal but usually the savings is not substantial.

A key quote from DPReview:
"Just an additional note: I keep reading that Nikon had it hard because it’s their first generation of mirrorless cameras. But I never heard the counter argument that in many aspects they actually had a much “easier” job to do than Sony. They knew in advance what they were competiting with, they knew in advance what people like and disliked from Sony cameras. To me this must balance the “first generation” argument. Sony had to figure out everything all alone in these years…"
