When you consider the parent companies, there is really no comparison. Sony is a hi-tech company that happens to make cameras, along with computers, televisions, who along with Philips developed the CD and is highly regarded as at the pinnacle of consumer grade electronics. Remember the Walkman, Disc-man and first Digital Cameras? For them to advance the technology of SLR cameras is only the natural course.
Gary mentioned that Canon now has a camera with an electronic viewfinder, so the technology is gaining favor, and he believes someday all camera makers will build electronic viewfinder cameras.
Most people have no qualms about praising a computer company for building a faster, lighter and more efficient computer, but when it comes to cameras, there seems to be a natural aversion to giving "the other guy" the kudos they deserve for making technical advances.
My first "real" camera was a TOPCON RE Super.
http://en.wikipedia.org/wiki/Topcon_RE_Super This is the VERY FIRST SLR camera to have TTL metering, and at full-open aperture. It was well built, had a removable prism and changeable focusing screens, an excellent 58 mm f 1.4 lens, removable back for the use of a bulk film magazine, had capability to add a motor drive and had the light meter viewable in the viewfinder. It was well ahead of its time. But, for the people I knew that owned the Nikon F, mine was just an also-ran. In fact, the US Navy standardized on the Topcon for many years because of its rugged metal case design, ease of use and excellent results. I used it for many years and developed and printed my own B&W photos, even aboard ship. It's safely stored away in a foam cutout briefcase. It even has a metal screw lid film can still taped to the leather neck strap. But, it was not long before other cameras had those same capabilities and then some. Technology advances. Life would be pretty boring if it didn't.
So, in the end, as Gary said, he "switched" to Sony because it was worth it for him because of the quick creativity it gave him. He said his wife also switched. They recognized, bought into and took advantage of the newer technology.
In this case, as in many others, sometimes it's OK to seriously consider the "other guy" because he just might have a better solution.
A lot of people still have that "Not Invented Here" attitude and sadly, may be missing out.
So, whatever you shoot, at least acknowledge that this might just be a preview of the future technology of your next camera.
And kudos to Sony for advancing that technology.
