Amazon calculates a product's star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Great camera, just as described. I bought this camera after a lot of research and I am happy to say that I was not disappointed! It is undoubtedly one of the best (if not the best) professional cameras in its price range. The seller shipped the camera promptly and I received it before the promised date. The only issue I had was that the camera packaging (the factory box, NOT the seller's packaging) had a some damage, which got me very worried. This seems to be due to the fact that the seller's packaging was pretty minimal and did not offer much protection. I have received way cheaper and less sensitive products with much better packaging. Thankfully, Sony's factory packaging seems to have done its job protecting the camera itself, which had no damage whatsoever.
