Canon EOS R7 vs Olympus OM System OM-1 Overview and Optics

The Canon EOS R7 triumphs over the Olympus OM System OM-1 in our optics comparison, with a score of 82/100 versus 69/100. Both cameras share similarities, including CMOS sensor types, image stabilization, and lens mounts specific to their respective brands. However, it is the differences in specifications that set the Canon EOS R7 ahead.

The Canon EOS R7 boasts a higher megapixel count of 33, compared to the Olympus OM-1’s 20 megapixels. This translates to greater image resolution, detail, and flexibility in post-processing. Additionally, the R7’s shooting speed is faster at 15 frames per second, as opposed to the OM-1’s 10 frames per second, providing an advantage in capturing fast-moving subjects. The R7 also benefits from a superior DXOMARK sensor score of 97, compared to the OM-1’s 85, indicating better overall image quality.

Despite its lower score, the Olympus OM-1 has some unique strengths. Its Micro Four Thirds sensor size offers a more compact form factor compared to the Canon EOS R7’s APS-C sensor. This may be appealing to photographers seeking a smaller and lighter camera system. Moreover, the OM-1 has a 4:3 aspect ratio, which some users might prefer for specific applications or personal preferences.

Taking into account these differences, the Canon EOS R7 outperforms the Olympus OM System OM-1 in terms of optics. Its higher megapixel count, faster shooting speed, and better sensor quality contribute to its superior score. However, the Olympus OM-1 offers a more compact sensor size and a different aspect ratio, which may be advantageous for certain users. Ultimately, the choice between these two cameras will depend on individual preferences and specific photographic needs.

Canon EOS R7 vs Olympus OM System OM-1 Video Performance

The Canon EOS R7 outperforms the Olympus OM System OM-1 in video capabilities with a score of 91/100 compared to the Olympus’ 83/100. Both cameras share common features, such as 4K video resolution and built-in time-lapse functionality. However, the Canon EOS R7 surpasses the Olympus OM-1 in certain aspects, while the Olympus OM-1 has its own advantages.

The Canon EOS R7 boasts a higher maximum video frame rate of 120fps, double that of the Olympus OM-1’s 60fps. This allows the Canon EOS R7 to capture smoother and more detailed slow-motion footage, providing a clear advantage for users who require this feature. Additionally, the Canon EOS R7 has a max video dimension of 3840 x 2160, which is suitable for most users’ needs.

On the other hand, the Olympus OM System OM-1 offers a slightly larger max video dimension of 4096 x 2160, providing a minor edge in video resolution. However, this advantage is not significant enough to outweigh the benefits offered by the Canon EOS R7, especially considering the lower video frame rate.

Taking these factors into account, the Canon EOS R7 emerges as the superior camera for video capabilities due to its higher video score, faster maximum video frame rate, and sufficient video resolution. The Olympus OM System OM-1’s marginally higher video resolution does not make up for its shortcomings, and therefore, it is not the better option for those prioritizing video performance.
