Sony - Konica/Minolta
I am a believer that if you are doing things right, you will always have customers.
If you are doing thing right, there is no need to sell your business to someone else - or even worse, get taken over because you are doing something so wrong, others believe they can do better. If Konica/Minolta was doing things right, Sony would never have opportunity to take them over, buy them out, or whatever happened.
I am not saying "do not buy" Sony ... just commenting on the Sony-Konica/Minolta relationship.
If I were buying a new camera - Sony looks very very VERY attractive. The Axxx models are packed with features. Sony seem to know what consumers want - their marketing folks know all the phrases to catch your attention - caught my attention
Because I already own a DSLR, and I've touched Canon, Nikon and Sony ... I would go with Canon xxD or Nikon's D80/D300. To me, Sony does not feel solid - it just feels light/flimsy. Probably intentional, but just does not feel right to me.
Lastly, I would go Canon for a very simple and noobish reason ... I can identify a pro-level lens by looking at description. Canon pro-level lens all have "L" in description. Nikon, I have to look at picture of lens for a gold ring. Sony - I have no idea.
