Thanks for that review and comparison Harmon.

Also when I compared the 300 on display at the SonyStyle shop to my 505 the black was not as black on the 300 though the background was a bit lighter -- exactly the same as my Astak PP screen. Doesn't make much difference in bright light as you say but it is definitely noticeable.
