A Siberian Journey with the Alpha 7R IV
By Sandy Wijaya
When I first used the Alpha 7R IV I was impressed with its versatility and high megapixel count. It is an extremely capable camera that not only produces spectacular stills but beautiful videos as well.

This fourth edition of the Alpha 7R has an updated 61 MP sensor and enhanced BIONZ X image processor. What this means is that it has magnificent imaging quality with a smooth gradient. It also has an impressive 15-stop dynamic range, the ability to shoot up to 10fps, Real-time Eye AF and Tracking AF.

Built to withstand the toughest conditions
On top of balancing the imaging merits, the Alpha 7R IV also sees an updated physical design with more robust weather sealing to suit working in especially harsh weather conditions. I tested this durability during my recent winter trip to Eastern Siberia. Both the camera and Sony GM lenses could withstand the extreme Siberian environment; in temperatures ranging from -31 to -25 degrees Celsius. Plus, one battery is more than enough for a full day outdoor shoot in such an environment, another giant leap in a mirrorless camera.

As a travel photographer who faces different kinds of situations and conditions around the world, I need a camera that is agile, robust and at the same time can deliver the best results possible. I have never had such confidence in a camera before until I chose the Alpha 7R IV.
Redefining creative boundaries
The Alpha 7R IV’s higher resolution gives me so much more freedom during the printing process. The 15-stop dynamic range means that the camera could retain and render as much tonality and detail as possible. The Alpha 7R IV performs amazingly when combined with Sony GM lenses. It delivers incredible results with the most details and brilliant sharpness.

In my opinion, noise handling is usually a challenge with all high megapixel cameras. However, despite being such a high-resolution sensor, the Alpha 7R IV has a flexible native sensitivity range from ISO 100-32,000. This makes it great for working in a variety of lighting conditions. Additionally, the Alpha 7R IV has kept the 5-axis SteadyShot sensor-shift image stabilization. This helps to minimize the appearance of camera shake by up to 5.5 stops of shutter speed compensation. It’s extremely beneficial for both stills and video operation.

Next-level resolution with Pixel Shift Mode
Another feature that I love is the Alpha 7R IV’s Pixel Shift Mode. This unique compositing mode allows you to achieve even greater resolution than the 61 MP sensor affords. Working in conjunction with the sensor-shift image stabilization, this mode shifts the sensor while making 16 consecutive exposures. This means the camera is able to gather approximately 240.8MP of information for greater color accuracy and detail than possible with a single exposure, along with an impressive image size of 19,008 x 12,672 pixels.

These files can then be merged together during post-production by using the Sony Imaging software suite. To deliver optimum results during creating Pixel Shift image in an outdoor situation, try to avoid fast-changing light conditions and moving objects.
