Electronic (OLED) Viewfinder on Sony Alpha 7R IV

Sony Alpha 7R IV has a built-in 0.5" Electronic (OLED) viewfinder with 5,760k dot resolution. It has a 100% coverage and 0.78x magnification. There is no built-in or optional viewfinder available on Nikon Coolpix L20.

Sony Alpha 7R IV features a 61.0 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.7 x 23.8 mm and a total area of 849.7 mm². Its native ISO range is 100 - 32,000 and expands to 50 - 102,800 in boosted mode.

Sony Alpha 7R IV has BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

Sony Alpha 7R IV is equipped with BIONZ X processor and can take pictures up to 9504 x 6336 resolution. Nikon Coolpix L20 can take pictures up to 3648 x 2736 resolution. It can also take pictures with lower resolution like 3584 x 2016, 2592 x 1944, 2048 x 1536, 1024 x 768, 640 x 480 with 4:3, 16:9 aspect ratios.

No Low-Pass Filter on Sony Alpha 7R IV

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Sony Alpha 7R IV. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization on Sony Alpha 7R IV

Sony Alpha 7R IV has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 5.5 stops of compensation. This means that you are still getting vibration reduction when camera is paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.
