Here's my experiences with Sony products:
1. Bought a Sony FE 35mm f/2.8 (one of the first people to buy it). The hood for it is nicely custom designed but two parts are glued together. The glue didn't hold after 7-8 month the two parts split (because of weak glue not cracks). Basically a manufacturing defect. So emailed customer service and said the two part of the FE 35 hood was not glued together properly and asked it to be fixed under warranty. The person replied back with a link to Sony website saying the hood is not supported because its not in the list of supported accessories on their website!! The hood is sold WITH the lens, it makes no sense to tell me that this product is not a part of this lens just because their website doesn't list it!! It was like speaking to a 5 year old (sent 5 emails back and forth). I just gave up and glued it back together my self (after finding a solution from someone else on Sony forums). Yes its an easy fix, just buy some super glue and fix it yourself because that's what sony would do, but the point is they are totally insensible.
2. Bought used SEL 10-18 from LCE. Notice it was decentered 5 months down the line. Contacted LCE and they asked me to send it back to them. They had it fixed by Sony no problem within couple weeks. I had to bear postage costs one way.
3. Bought a new Sony TV from John Lewis. Broke 4years 10month into 5 year warranty. Called up John Lewis, they simply replaced the whole LCD panel basically making it a new TV!
Moral of story, buy from a reputed dealer that'll deal with Sony for you! May be their pro support is better...
