Sensors are the main battleground in the camera industry, and Gpixel's latest appears to be well aware of that fact. The company has created a 49-megapixel, HDR, backside-illuminated, stacked sensor capable of up to 8K at 120 frames per second.

A teardown by astrophotography site LandingField found that the 12-megapixel Alpha 7S III is using four photosites to create a single pixel, meaning its actual resolution is 48-megapixels. Some have taken this to mean that it uses the same sensor as the Alpha 1.

Pixii, the company behind the Pixii Camera originally announced in 2018, has unveiled an upgraded version of the APS-C M-mount rangefinder that boasts a new 26-megapixel sensor, USB-C support, a new "interactive" viewfinder, and a $3,000 price.

What is the most important aspect of a camera to consider when looking to buy a new one? In this video, Engadget put camera sensors in the spotlight and reviewed how they have improved and what role they play in today's photographic equipment.

Fujifilm has announced that it is currently developing a new flagship camera that will feature the company's first back-illuminated, stacked layer X-trans CMOS sensor.

Phase One has announced the iXM 100MP, a 100-megapixel medium format camera for drones that's the first camera to feature Sony's 100MP backside-illuminated (BSI) 44x33mm sensor. It's "a breakthrough aerial camera platform driven by the world’s fastest medium-format imaging sensor," Phase One says.

It looks like the hype surrounding the new Sony a7R II is justified... at least when it comes to sensor quality. DxOMark tested backside-illuminated full-frame sensor in the camera -- a world's first -- and the sensor received the highest overall quality score ever awarded by the testing lab.
