Today Sony announced the newest addition to it's mirrorless line. The Sony a7R Full Frame Mirrorless camera. They also released a smaller megapixel mirrorless camera the a7. The a7R has a 36.4 megapixel full frame sensor. The a7 has a 24.3 megapixel sensor. So what does this mean? Well first off, if you don't know already, Sony makes the sensors for some of the Nikon DSLRs. This includes the highly regarded Nikon D800. If you look at the megapixel count for the Sony a7R you will notice a 36.4 megapixel. The D800 has a 36.3 megapixel sensor. Interesting right? Also a feature of the a7R is the absence of an anti alias filter. To make a short story long, the new Sony a7R is a Nikon D800E in a mirrorless camera body.
Granted the autofocus of the D800 may be better, but I am willing to bet if you have a D800 you're probably not shooting action as your main genre of photography anyways. So what I am basically telling you, is that Sony has took this mirrorless thing to a whole new level. It's no longer a joke. It's no longer something pros should ignore.
You can get a Sony a7R for $600+ cheaper than the Nikon D800E. The Sony is less the half the weight of the D800, oh ya, Sony has also released a couple Zeiss lenses as well. With this camera you get a renowned sensor, with world class optics, all in a lighter, more compact, and cheaper package. The rest of the options and features you can nitpick over, but lets be honest, Sony may have just revolutionized the camera.
I would love to test drive one, as it may be my new camera system!
