Thanks for the detailed and interesting review Kevin. At a technical level Sony has been at the forefront of some amazing technological innovation that works very well. I am currently using an a6300 with the Zeiss 16~70mm f/4 E-mount lens, and I find the performance of this combination to be quite stellar, even at very high ISO settings.
All that said, I must take issue with one sentence in your review, and it is this one:
<<They proved that as a company they listen to their customers and deliver what their customers ask for.>>
Well, I'm sorry to say, but in my case nothing could be further from the truth. The Achilles heal of this camera system, and I don't know for how many Sony sensor models this applies, but for the a6300, there is a real problem with sensor cleaning. For any cleaning other than a rather useless in-camera algorithm that does nothing, Sony tells us to send or bring the camera to a Sony service center. I can't think of anything more foolish for an interchangeable lens camera that is supposed to be usable in a wide variety of clean and not so clean field environments where there is no sensor cleaning facility anywhere near at hand.
For example, last November I discovered stubborn dirt on the sensor two days before leaving for a field shoot in London England. I tried using the usual solution - Eclipse, and it created such a mess on the sensor I thought I had destroyed it. I was directed to a Sony service center fifty miles from Toronto, where I took the camera and they restored the sensor to its original condition. And they told me not to use Eclipse in the future but to bring it to them. I asked them what fluid they used on the sensor and they refused to tell me, citing the cleaning process as "confidential".
Not satisfied with this nonsense, I took the matter up with the management of Sony Canada, which is a puppet operation whose strings are pulled by Sony USA. They refused to answer the question also, citing confidentiality, and further telling me this is the position of the corporation as a whole. I compared this position with that of Phase One which even makes the correct fluid available to customers for its very high-end digital backs. They weren't interested. Not one to take this kind of rubbish lying down, I sent a very crisply drafted letter to Sony senior management in Japan advising them that I needed an answer to the question of how to clean by own sensor, failing which I would have to presume there is some kind of generic defect in the technology which rendered it ill-advised to let consumers near their sensors. I sent the letter by registered mail and I know they received it, but Sony Japan never answered it - from going on five months now.
In light of this experience, all I can say about Sony's bedside manners is (a) they DO NOT listen to their customers, and (b) they treat their customers with disdain and disregard. Any one contemplating the purchase of a Sony camera can well appreciate its technical virtues, but don't count on that outfit for customer relations. They have a lot to learn.
Post-scriptum on this case: after the initial episode I had asked for advice about Sony sensor cleaning on this Forum and some readers were good enough to offer suggestions that they say works. I am grateful for that, but really and truly, there is no substitute for the company backing its product by telling its customers what is usable and not usable for cleaning its own sensors.
