I have been using Sony system for more than a year. I never felt Sony does not perform to its expectation. I never decide to change to a different system because I am following my friends, nor being influenced by them.
What I missed about Sony Alpha is its capability to produce wonderful images on .jpeg format and its camera’s body built-in, Super Steady Shot. These are two factors that are important in producing good photos. No doubt, lenses also play as vital role in image IQ. So the Carl Zeiss optics is surely to be missed.
Sony Alpha has taught me to use a camera as a tool, with the most difficult part of composition, and using limited resources to take good photographs. I am not saying my photos are excellent. Its just that, with the limited 9 points focusing and high isos, I have learned how to manipulate that limitations to so far, the best image reproduction I can get. For that, I thank Alpha ranges, for the learning curve.
The turning point for me to have an open mind about other systems, and not being a fanboy of Alpha, was when I bought a compact camera recently, Panasonic Lumix LX-3. I was amazed what a small midget can actually produced an image quality somewhat at par with my A550. That was the start.
I first saw Canon 7D when I watched the advertisement of Ken Watanabe (The Last Samurai, Iwo Jima to name a few) playing the role as the man behind the camera. That made me felt curious to find out more about what Canon EOS 7D can do.
I have been in and out of forums, camera websites, photography magazines in search of information of EOS 5D Mark II and 7D. I do like the functions of 1D ranges especially the Mark IV, but I need a DSLR that is lightweight for travelling.
The next question was, do I really need a full frame (35mm format). I have been using A900, and I know what is its advantages and disadvantages. But do I really need a full frame as an amateur photographer? Photographing as a hobby? I listed down all the pros and cons, and it is time to buy. To make a choice. What area of photography I do most and getting the output that I wanted.
I chose EOS 7D from 5D Mark II, simply because of its features, and my photography style.

I will not discuss the technical of getting the above photos, however, what I can say is that, I used less time and was doing right the first time for each photos I shot above, without difficulty. With that I have to admit the difference 7D can do.
This saturday I am heading to Jakarta for my Alpha gears sales. Goodbye my beloved A900, and my reliable lenses. Thank you for the good photography year of 2009.
