I sense really awful sourness. I was like that too.
I have an a330 and I got it because their cybershots were decent and they distributed their catalogues to my house. Simply that.
Undoubtedly, Sony has two main things to boast about: Built-in sensor stabiliser and AF CZ lenses.
I have tried using the 55-200 on my a330 and another 70-200L f/4 IS on a 550D and honestly, it is very different so I don't see how it can be compared.
Regarding the AF CZ lenses point, I don't see why so many people are overrating it. It's not like they converted all of their legendary lenses just for Sony. Let's face it, it makes Sony's 24-70, 16-35 and a few others and these lenses are not absent in C/N's lineup. It could be because Sony doesn't have the reputation of making kick ass glasses so they found CZ who has been providing with lenses for cybershot and has a reputation of doing that. It's just another another class of lens in the Sony's lineup.
I think it's perfectly fine to fanboy for a while and self-comfort for a while but it's not when people just do it excessively, like how some of us dislike those C/N people who overrate their stuff too.
I am not using a Sony anymore because I needed the high iso performance which is present in other brands, I don't see anything wrong with it. It's not lack of loyalty but if Sony had a high iso full frame model in addition to their 2 similarly spec-ed FF, I would have got that FF. But no and that's not a good thing. But if I were a full time studio photographer now, I would switch back to Sony and get an A850.
Regarding those ignorant mainstream users who think Sony is worse than Nikon/Canon, I don't think there's any need to actually get so angered by them. They are just ignorant. Just be contented that you actually had the chance to use a brand, as good as theirs, but at a lower cost.
