Detailed Comparison

Image Quality

The Sony A7R IV has a significant advantage in terms of image quality due to its higher resolution of 61 megapixels, compared to the Canon EOS R8's 24 megapixels. This allows the A7R IV to capture more intricate details and provides greater flexibility when cropping or printing large images. However, the EOS R8 still maintains excellent image quality with its full-frame sensor, handling high ISO performance commendably. The Canon camera's ISO range of 100-102400 provides versatility in alternative lighting conditions, although it may not match the extensive ISO performance of the A7R IV when extended to ISO 50. In general, both cameras produce exceptional images, but the A7R IV is the clear choice for those prioritizing resolution and detail in their work.

Winner: Sony A7R IV

Autofocus System

The autofocus systems of both cameras are impressive, but they cater to somewhat different user needs. The Canon EOS R8 features an advanced system with 1053 autofocus points, providing extensive coverage and quick focusing capabilities, ideal for capturing fast-moving subjects. On the other hand, the Sony A7R IV is equipped with 567 autofocus points, which are also highly effective but not as numerous as the R8. Both cameras utilize electronic viewfinders, enhancing the shooting experience. While the A7R IV benefits from Sony's proprietary Real-Time Eye autofocus tracking, the R8 also performs exceptionally well in tracking subjects. This aspect leads to a relatively close competition; however, the R8 slightly edges out in flexibility and coverage.

Winner: Canon EOS R8

Video Capabilities

For videographers, the Canon EOS R8 stands out with its ability to record 4K video at up to 60p, making it a more attractive choice for those seeking high-frame-rate video options. In contrast, the A7R IV's video capabilities are limited to 4K at 30p, which may be satisfactory for many users but does not offer the same versatility as the R8. Furthermore, the lack of built-in stabilization in the EOS R8 is a disadvantage for handheld shooting, particularly in dynamic situations, while the A7R IV boasts 5.5 stops of in-body stabilization. If speed and frame rate are prioritized, the R8 wins; however, for stabilized shots, the A7R IV has the upper hand.

Winner: Canon EOS R8

Build & Ergonomics

Both cameras feature durable weather-sealed bodies, making them suitable for outdoor use in various conditions. The Canon EOS R8 is noticeably lighter, weighing 461 grams compared to the 665 grams of the A7R IV, which can be appealing for long shooting sessions or travel. Additionally, the EOS R8's dimensions make it slightly more compact, enhancing its portability. The A7R IV, although heavier, provides a more substantial grip for users who prefer a solid feel when handling the camera. While both models have electronic viewfinders and a tiltable LCD screen, the R8's screen has a higher resolution, offering a slight advantage in display clarity.

Winner: Canon EOS R8

Battery & Storage

The Sony A7R IV offers a more robust battery life, rated at approximately 670 shots, which is beneficial for extended shooting sessions. In contrast, Canon has not specified the battery life, but generally, the EOS R series cameras tend to have less endurance in comparison. In terms of storage, both cameras utilize similar SD card formats, ensuring a straightforward transition for users who already own compatible cards. However, the A7R IV's superior battery performance gives it an edge for professionals who may be shooting for longer durations without the opportunity to change batteries frequently.

Winner: Sony A7R IV

Value for Money

When it comes to pricing, the Canon EOS R8 at $1499 represents a significantly more budget-friendly option, especially for enthusiasts who may not need the high resolution and advanced features of the A7R IV, priced at $3500. The R8 provides excellent value given its features, making it suitable for various shooting scenarios, especially for those looking to break into full-frame photography without a substantial financial commitment. Conversely, the A7R IV is aimed at serious professionals who require higher image resolution and more advanced capabilities, justifying its higher price tag. Overall, for those seeking the best bang for their buck, the EOS R8 is the better choice.

Winner: Canon EOS R8

Our Verdict

Ultimately, the Canon EOS R8 emerges as the overall winner for most users due to its competitive pricing, higher autofocus capabilities, and substantial video performance. It appeals particularly to enthusiasts and semi-professionals who prioritize a lightweight design and good value. In contrast, the Sony A7R IV's strength lies in its superior image quality and battery performance, catering primarily to professional photographers who require the highest level of detail and reliability. Depending on specific needs, both cameras have their strengths, but for an all-around versatile choice, the EOS R8 is the better option.
