The Sony a7R IV outperforms the Nikon D750 with a score of 84 to 68. Both cameras share similarities, such as their announcement dates and launch prices in 2014 and 2019, respectively. They also have comparable sizes, with the Nikon D750 measuring 141 x 113 x 78mm and the Sony a7R IV at 129 x 96 x 78mm.

The Sony a7R IV has the advantage of being a mirrorless camera, which contributes to its lighter weight of 665g compared to the Nikon D750’s 750g. This makes the Sony model more portable and convenient for photographers.

On the other hand, the Nikon D750 is a DSLR camera, which some photographers may prefer due to its optical viewfinder and longer battery life. However, the Sony a7R IV’s higher score indicates that it offers better overall performance and features.

Taking all factors into account, the Sony a7R IV is the superior camera, but the Nikon D750 still has its merits, especially for those who prefer DSLR cameras.

Nikon D750 vs Sony a7R IV Overview and Optics

The Sony a7R IV outperforms the Nikon D750 in optics with a score of 85/100, compared to the D750’s score of 71/100. Both cameras share some common specifications, such as a CMOS sensor, full-frame sensor size, and compatibility with a variety of lenses through their respective lens mounts: Nikon F FX for the D750 and Sony FE for the a7R IV.

The Sony a7R IV excels with its impressive 61.2-megapixel resolution, significantly higher than the Nikon D750’s 24.3 megapixels. This allows the a7R IV to capture more detail and produce larger prints. Additionally, the a7R IV boasts a faster shooting speed of 10 frames per second, compared to the D750’s 6.5, enabling it to capture fast-moving subjects with greater ease. The a7R IV’s sensor also has a higher DXOMARK score of 99, compared to the D750’s 93, indicating better overall image quality. Furthermore, the a7R IV comes with image stabilization, a feature absent in the D750, which helps reduce camera shake and blur in images.

On the other hand, the Nikon D750 has the advantage of the widely compatible Nikon F FX lens mount, which offers access to a vast selection of lenses. This could be beneficial for photographers who already own Nikon lenses or prefer the Nikon lens lineup.

In terms of optics, the Sony a7R IV clearly outshines the Nikon D750 with its higher resolution, faster shooting speed, better sensor score, and image stabilization. However, the D750’s compatibility with the extensive Nikon F FX lens lineup may still appeal to some photographers. Ultimately, the choice between these two cameras will depend on individual preferences and priorities in terms of image quality, shooting speed, and lens selection.
