The Sony Alpha 37 , also known as Sony SLT-a37 , is an entry -level camera in Sony's α series. It is a digital camera with a partially transparent mirror, which the manufacturer Sony calls a single-lens translucent camera ( SLT camera ). It is the further development of the Sony Alpha 35 and - contrary to the nomenclature - has been replaced by the Sony Alpha 58 . It was introduced in Germany in June 2012.

technical features

A CMOS sensor in APS-C format with a resolution of around 16  megapixels was built into the camera . Its maximum light sensitivity is ISO 16,000, but the automatic only uses the range up to ISO 3,200. With very high ISO values, the camera offers the option of adding 6 images to a single one in order to minimize the noise.

A special feature of the SLT camera from Sony is the semi-transparent mirror. With a conventional single-lens reflex camera (DSLR), the mirror must fold down when using the viewfinder so that a picture can be taken. This means that time is lost until the recording is made, which can be negative for series recordings. This problem is to be circumvented by the semi-transparent mirror: The mirror sits statically and reflects part of the incident light. The camera has two separate sensors: one for recording and one for the viewfinder.

As a result, in addition to the display, the image to be expected can also be viewed beforehand using the electronic viewfinder. Another advantage of this technology is that the fact that there is no need to flip the mirror enables a higher speed of serial images.

The camera enables video recordings in up to FullHD resolution with a frame rate of almost 50 fields per second. AVCHD and MPEG-4 are available as possible video formats .

Individual evidence

1. ↑ Sony (along with other manufacturers) counts the subpixels of each pixel, i.e. H. the red, green and blue channels of each pixel individually, and therefore specifies the viewfinder display as 480,000 [pixels] × 3 [color channels] = 1,440,000 pixels.
2. ↑ Sony (along with other manufacturers) counts the subpixels of each pixel, i.e. H. the red, green and blue channels of each pixel individually, and therefore specifies the rear display with 76,800 [pixels] × 3 [color channels] = 230,400 or approx. 230,000 pixels.
