Sony to Canon
Interestingly, just like Mickbab who is one of the first to respond to this thread, Up to a few weeks ago I used a Sony Alpha300 with great success for several years. The camera served me very well and took very good pictures. I just got a new Canon 60D and I love it!
The Sony did get me hooked on the articulating LCD screen. Although I'm old school and use the viewfinder for almost all of my shots, the articulating screen is great for overhead (over crowd), or very low shots.
I tried to like the transparent mirror Sony, but the camera follows the trend and is too darn small in my hand. I have big hands and I like a camera body that allows me to get all of my fingers on it to hold onto it.
I shot Canon for film so I had some lenses, and even a wireless shutter release. The fact that all Canon lenses work with the 60D was a plus to be sure.
The Canon 60D was like putting on an old comfortable pair of shoes, and it takes very good pictures with exceptional color saturation.
But for those looking for a great small body camera, look at Sony, they are making good stuff.
