Okay, History lesson. Dial the calendar back to 2005, when I began to seriously look at the film to digital conversion, having really gotten into my photographic education.
I had bought into the Minolta Maxxum camera system back in October of 1985 and it had true AUTOFOCUS. After years and years of having to manually focus the camera, this new autofocus system could do it in the dark (with the 2800AF or 4000AF flash added)! That was pretty novel, back then... and, of course, all the manufacturers went to it, after "The Mind of Minolta" stole the show. Okay, Minolta had something special to continue with and an expectation of greatness to uphold. That 9000 camera was so good and cheap to operate, back then, I was still using it for my schooling in 2005.
Unfortunately, Minolta began playing around with the proprietary hot-shoe, back in 1995, and they lost a lot of interest in their product, as many people did not want to migrate from the standard ISO hot shoe and replace all their flashes to accommodate this new one. In fact, SONY has only just started to go back to the ISO hot-shoe, in the newest cameras. Regardless, in 2005, Minolta was bankrupt and sold itself off in a rather weird fashion to SONY, who had sat to the side and starved out Minolta to get their price. When the transfer finally happened, only about 65% of the Camera Division remained, as Minolta had begun selling off smaller, choice pieces to other interested parties. A lot of spare parts were lost in this and many unsold lenses went to SONY without any spare parts support. If your lens broke, they either replaced it or gave you your money back.
Okay, where I came in, I knew Minolta was "belly-up" in Feb 2005 and I still needed a digital SLR for school. I thought about getting a new Minolta 7D w/ Anti-Shake Technology, but with Minolta bust... getting that camera repaired, if it ever failed, just seemed impossible. Because of that issue, my decision wound up being either Canon's 20D or Nikon's D70s, back then. I actually bought both to look at and went with the Canon, in the end, returning the Nikon. I spent a carload of cash to outfit the Canon-system, with four 580 flashes, stabilized lenses and other Canon exclusive stuff, while all my nice Minolta Maxxum lenses sat idle in their cases. Meanwhile, going on in the background, SONY acquired Minolta's factory remains and they finally released the SONY a100 in July 2006. I bought one the second day is was on the shelf and put it right up against the Canon 20D.
Now, you must consider that the SONY a100 was a temporary camera to appease the disgruntlked Minolta folks. It was a "prototype" to the finalized SONY a700 (which came out a full year later). The a100 was missing a lot of the advanced features, such as studio flash triggering and a vertical grip, but with "Super SteadyShot" inside, it gave me a lot more "keeper" shots than the Canon ever could, handheld, indoors. If you didn't have an expensive stabilized Canon lens on your 20D, you were, indeed, suffering. The SONY a100 gave stabilization to EVERY lens you mounted (zoom, prime, tilt-shift), even manual ones... for no extra cost! Hard to argue with that kind of bargain. In fact, it is because of the SONY a100 that Canon and Nikon had to reduce the cost of their stabilized lenses to something more reasonable. Cause and effect.
So, after having spent thousands in glass for the Canon-system, as soon as the SONY a700 was released (Sept 2007), I began selling the Canon glass and flashes off and replacing it with SONY/Minolta A-mount equivalents. Within a month, I had every lens replaced and even had a couple new types, MACRO and Tilt-Shift. The a700's 12.2MP was more than a match for the Canon 20D/30D 8.1MP images. "Super SteadyShot" had made its point and I was looking forward to SONY finally delivering a stabilized FF-design. In 2008, they did. The SONY a900 was released, but the $2999.99 price point was far more than many APS-C shooters could justify. The price was soon reduced to $2699.99, but still the migration to Full Frame was not happening. SONY then offered the a850 @ $1999.99 and it was, for the most part, a 3-fps a900. That did it and the a700 shooters made the leap. I along with them. Shooting Full Frame was almost "cost-effective." I say that because the cost per picture, in computer storage is a lot higher. Each Full Frame image is 24.6 MP... or about 18-32MB. That's a lot more than 12.2MP images. You had to grow your PC's resources to manage images that large, in speed, memory and storage. Going "Full Frame" is a big step up.
Anyway, in my opinion... SONY seems to still, to this day, be in need of learning still-photography needs from the users. SONY has always seemed to love their movies and little Point&Shoot cameras. They are not Minolta... and fail to understand the legacy shooters who are often incensed by the blatant disregard of requests made to the SLR camera division. Most photographers are not interested in the "latest" release of equipment, like the much younger P&S crowd is. These devotes are looking for the most reliable and flexible solution to their image-taking, especially the hobbyists. Most serious equipment costs thousands of dollars and you do not want to have to replace that, just because some manufacturer wants to try a new gimmick out. Obviously, it would empty a person's wallet out pretty quick and makes you quite humorless doing so.
So, SONY bought the "alpha-mount" and was traipsing along, gradually adding new glass to the roster and retiring that which it could not support, due to the SNAFU that occurred during the Minolta Camera Division debacle. Then comes NEX and the "E"-mount. Panic quickly strikes the heart of all the A-mount crowd, as here comes another unasked for change. No one wants to give up their legacy glass and have to buy it all over, again, just to accommodate a new camera. Whatever boardroom decisions took place, a big sigh of relief was felt when the SLT change was all that we had to tolerate. It was still an Alpha-mount... and life could continue without the heartbreak of involuntarily retired glass sitting in some closet... AGAIN!
So, you ask... why SONY? I often wonder. They don't seem to listen very well.
