About recent cameras

The camera we are currently using is a Nikon D800E. Two and a half years ago, in order to switch to this camera, I sold the Canon 5Dmark2, including the lenses.
My current regular lens is the classic NIKKOR 14-24mm f/2.8G.
The D800E was from Kawasaki's EX building, and the 5D2 was from TokyoGreatVisual, and until then it was Leica and analog.
It's a set of unparalleled overwhelming resolution and image quality that can't be complained about, but there are a few dissatisfaction points.
・It is a lens with excellent resolution to the periphery, but the distortion is large and the shape is not simple, so even DXO can not correct it perfectly (only the person concerned). Framing is also difficult. I don't think you can beat a single focal length lens.
・Because it is large and heavy, it is troublesome to take family photos other than architectural photos.

Recently, there are actually more interesting models.
Sony's α7R.
I've been waiting for a mirrorless SLR for a long time. The mirrorless camera created by Panasonic was an ideal solution that actively incorporated digital correction suitable for the digital age. However, in terms of image quality, it still cannot beat a full-size SLR. Then came the α7R.
This model is a full-frame mirrorless interchangeable-lens camera.
In other words, since there is no mirror between them, the body can be made smaller while using a 35mm full-frame sensor, and the sensor and lens can be brought closer together, so it is possible to develop a high-performance and small lens, and the price is low.
Image resolution is on par with the D800E.

What's even more interesting is that you can install apps on your camera.
For example, if you install an application called Lens Correction and create presets for old lenses, you can correct various aberrations even with old Leica lenses. It seems that it also supports videos.
As someone like me who used Leica, I can still use the ultra-wide-angle 12mm and 15mm lenses that I used to take photos of when the camera was completed.

It is a digital camera that was introduced because it is digital, but it can be said that it is a digital camera that is extremely close to analog.

I have written before that digital cameras are similar to the mechanism of the eye, but I think the ultimate digital camera is a camera with a hemispherical sensor similar to the retina. Various corrections will become easier, and I think you will be able to create an ultra-compact, high-quality camera. The advantage of a wide-angle lens is more pronounced. The structure is closer to the body. In fact, Sony seems to have already developed it, and I am looking forward to its appearance.
