Sony A7R IV

While 61 megapixels provides incredible detail for large prints and heavy cropping, it does create very large file sizes. If you primarily share photos online or don't need to make massive enlargements, you might find the file management requirements more demanding than necessary.

The real-time tracking is highly reliable, locking onto both human and animal eyes with impressive precision. It excels at keeping fast-moving subjects sharp, making it a strong choice for portraiture and action photography where focus accuracy is critical.

Yes, the A7R IV features a robust, weather-sealed body designed to resist moisture and dust. It is built to handle professional field work, though it is always wise to pair it with weather-sealed lenses for full protection.

The 5-axis stabilization significantly reduces blur caused by camera shake, allowing for sharper handheld shots at slower shutter speeds. However, for long exposures or critical studio work where absolute stillness is required, a tripod remains the gold standard.

Dual UHS-II SD slots provide essential redundancy for professional workflows. You can configure the camera to record to both cards simultaneously as a backup, or use the second slot to extend your storage capacity without stopping to swap cards.

The A7R IV is capable of shooting 4K video with excellent detail, but it is primarily designed as a high-resolution stills camera. If your work is video-first, you may want to compare it against Sony's dedicated cinema or video-centric mirrorless models.
