Just rambling.
I was messing around with my Father in Law's old Minolta Maxxum 7000 (one of the first AF technology) and 25 year old AF Minolta lenses on my buddie's Sony A55 body. AF works beautifully which gave me some smirk. Decided to do some research on what happened to Minolta. Well, Minolta had to pay Honeywell $127 million in a patent infringement lawsuit in the 80's. Evidently Norman Stauffer, an engineer for Honeywell had some key patents on Auto Focus technology from the early and mid 70's in which Honeywell waited until Minolta Maxxum was launched and had a sizable sale in the US before they filed a lawsuit. Minolta lost and had to pay. I don't know that bankrupted Minolta but you didn't hear much about them in the 90's.
2005 Sony acquires Minolta and all that good Auto Focus technology. Honeywell patent has long been expired. I personally think Sony A55 must be a fantastic little camera. But further reading taught me that Nikon buys sensors from Sony... Wow I didn't know.
Granted, Sony lens line up can't compete with Canon or Nikon, at least not right now.
I really don't know much about Sony's DSLR bodies and performance other than A55 winning the Camera of the year in 2010..I think. Can Sony compete in the DSLR market against Nikon and Canon? I hope so.
Oh and thanks Honeywell for nothing other than a few Honeywell Pentax and leeching off other companies with the AF patents. Strong Minolta could have made the DSLR market more interesting today.
Just a little musing.
I have to admit all the features of the A55 gave me pause. I've seen some incredible videos on vimeo that were done using the A55 as well as stunning photos on flickr. It's priced well too. There does seem to be way more accessories, lens options, etc for canon though.
