SUMMARY
Choosing an interchangeable-lens camera involves committing to a mount system, which dictates the available lenses and accessories. This lens ecosystem is more critical for long-term satisfaction than body specifications such as megapixels or burst rates, which matter little for beginners. Sensor size, particularly APS-C, offers a balance of image quality, size, and cost, making it ideal for most new photographers. While full-frame offers advantages, it comes at a significantly higher price, and Micro Four Thirds provides a compact option with good stabilization. Important features to consider include autofocus and a viewfinder, while advanced video specs are less relevant for still photography beginners.
