Canon M6 Mark II vs Rebel SL3 Overview and Optics

The Canon EOS M6 Mark II outperforms the Canon EOS Rebel SL3 in optics, scoring 62/100 compared to 61/100. Both cameras have a CMOS sensor, Digic 8 processor, and APS-C sensor size. However, some differences give the M6 Mark II an edge and some advantages to the Rebel SL3 / 250D.

The M6 Mark II has a higher megapixel count at 33, compared to the Rebel SL3 / 250D’s 24. This means the M6 Mark II captures more detail in images, allowing for larger prints and more cropping flexibility. The M6 Mark II also has a significantly faster shooting speed of 14 frames per second, compared to the SL3’s 5 frames per second. This makes the M6 Mark II better suited for capturing fast-moving subjects and action shots.

On the other hand, the Rebel SL3 has a higher DXOMARK sensor score of 64, compared to the M6 Mark II’s 58. This implies better overall image quality and improved low-light performance. Furthermore, the SL3 / 250D features image stabilization, which the M6 Mark II lacks. This helps reduce camera shake and produces sharper images, especially in low-light situations or when using slower shutter speeds. The SL3 / 250D also uses the Canon EF/EF-S lens mount, providing a wider range of lens options than the M6 Mark II’s EF-M mount.

While the Canon EOS M6 Mark II has a slight advantage in optics due to its higher megapixel count and shooting speed, the Rebel SL3 / 250D offers some benefits, such as a better sensor score and image stabilization.

Canon EOS M6 Mark II vs EOS Rebel SL3 Video Performance

The Canon EOS M6 Mark II outperforms the Canon EOS Rebel SL3 in video capabilities, scoring 91/100 compared to the latter’s 83/100. Both cameras share some common specifications, including 4K max video resolution, 3840 x 2160 max video dimensions, and built-in time-lapse functionality. However, the EOS M6 Mark II offers superior performance in specific areas, making it the better choice for video enthusiasts.

One of the main advantages of the EOS M6 Mark II is its higher max video frame rate of 120fps, compared to the Rebel SL3’s 60fps. This allows for smoother, more detailed slow-motion footage, which can be crucial for capturing fast-moving subjects or creating cinematic effects. The higher frame rate also provides more flexibility in post-production, giving users the ability to slow down or speed up footage as needed.

While the Rebel SL3 / 250D may not match the EOS M6 Mark II in terms of frame rate, it still offers solid video capabilities for its price point. With 4K resolution, built-in time-lapse functionality, and a max frame rate of 60fps, it is a suitable option for casual videographers or those on a budget. However, those seeking the best possible video performance should opt for the EOS M6 Mark II.

Considering their respective video scores and specifications, the Canon EOS M6 Mark II stands out as the superior choice for those prioritizing video capabilities. Meanwhile, the Canon EOS Rebel SL3 / 250D remains a viable option for casual users or budget-conscious buyers who still want quality video features.
