The vision of a system changer

I switched from my D7000 for Alpha77.
And am glad to have gone this step.
What I am particularly impressed at the A77, the image quality, the electronic viewfinder, the integrated image stabilizer and the GPS.
At first I was skeptical of the electronic viewfinder, now I can no longer do without. The fact that the effect can be seen at any setting (WB, exposure, ISO, etc.) directly in the viewfinder, allowing a completely different type of photography.
Since I professionally much travel and often do not know where a photo was taken, I find the GPS feature very handy for later photo management.
The case is very ergonomic, robust and weatherproof. The camera's menu is well designed and the buttons are partially free configurable.
The integrated image stabilizer, I feel as huge advantage over my old Nikon, because now I can take pictures stabilized with my lenses.

Not only in relation to the electronic viewfinder I was skeptical at first, but also in the 24 megapixels and the associated noise performance.

It was clear my D7000 in High ISO range at first glance a little better, but if you reduced the photos of A77 on equivalent 16 megapixels, a distinction is no longer detectable. So I have in good weather very deteilreiche 24 megapixels and in low light just 16 megapixels. Therefore, I see in the enormous number of pixels not a disadvantage, but rejoice (assuming good lenses) over the level of detail.
In addition, you can also use the multi-frame noise reduction that delivers really surprisingly good results with static subjects.

On the whole, the benefits outweigh the A77 so strong that I have seen over my initial doubts away and have taken the change of system from Nikon to Sony.
If one of the two "big" camera manufacturer produces such a camera, they would have probably declared over camera.

PS: As a book tip I can recommend the work of Gary Friedmann to A65 / 77, there the camera functions are described very understandable to the smallest detail. Especially for system changer or newcomers who are not familiar with the Sony features a sensible investment.
