Main Features

Let us now see some of the important features of both the devices in detail.

Lens
The A7 and A7R cameras are equipped with interchangeable lenses that will excite professional photographers. These lenses haven't changed from the previous launch, with both the devices using the E-mount Carl Zeiss lenses. If you are confused as to how such a big lens could fit into the camera, you will be surprised to see how perfect this arrangement is. And as long as you can click good photos, I don't think anyone is complaining.

Crop Mode and Full-frame Mode
In the crop mode, the A7 camera can click pictures in 10 megapixel resolution, and in full-frame mode, the resolution is 24.3 megapixels. In the crop mode, the A7R camera uses only 15 megapixels of the total 36.4 megapixels that are available in the full-frame mode.

Autofocus
The enhanced Fast Hybrid autofocus in A7, which includes phase detection and contrast detection features, makes this launch the fastest autofocusing camera among the lot. It has 117 points phase detection AF and 25 points contrast detection AF. The A7R has a 36.4 megapixel full-frame CMOS sensor, without any anti-aliasing filter. However, the contrast detection AF with 25 focus points autofocus is available.

Display
You can view shots on the high resolution XGA OLED Tru-Finder or the 3.0-type tiltable LCD screen. This screen can be up by approximately 90 degrees and down by approximately 45 degrees. These images can be viewed on any 4K or Bravia television with Triluminos display, thanks to the Triluminos Color support.

Video Recording
You can shoot full-HD videos (the button is provided at the side of the camera) with ultra-low noise even in lowlight backgrounds. With the help of the Clear Image Zoom feature, you can take closeups while shooting videos, without compromising on the pixel count. Near the video button, you will find a microphone, headphone, and a clean HDMI port that can used for displaying images/videos on an external monitor. The videos are recorded in P, A, S, and M modes.

Connectivity
The NFC and Wi-Fi options offer one-touch connectivity with other compatible Android and Xperia devices. If you are interested in group shots or self-portraits, you will be excited with the Smart Remote Control, which can control exposure and shutter release alongside automatic photo sharing with your mobile device.

Body
The camera body is weather-sealed due to the tough magnesium alloy that is used.

The pre-orders for these cameras have already begun, although shipping is slated to happen in the coming months. These cameras, due to their high-quality lenses and imaging techniques, will definitely give the best possible results. Look forward to a great buy this holiday!
