Canon's enthusiast APS-C DSLR with 15.1MP sensor, improved AF, and DIGIC 4 processing.
The Canon EOS 50D was released in 2008 as the enthusiast APS-C DSLR update to the 40D, featuring a 15.1MP CMOS sensor and 6.3fps burst rate. No video recording — the 50D was the last Canon APS-C DSLR to ship without video; the 2009 EOS 500D (Rebel T1i) introduced video to the Canon APS-C lineup. BP-511A battery. At approximately 822g with battery and card.
15.1MP APS-C CMOS sensor with DIGIC 4. 9-point AF. 6.3fps continuous burst. No video recording — stills only. UDMA CompactFlash card. BP-511A battery. Body weight approximately 822g with battery and card. LiveView available but no video capture. No weather sealing.
The 50D sits at the end of the pre-video Canon enthusiast DSLR era: 15.1MP was the highest APS-C resolution Canon offered at launch, and the 6.3fps burst covered sports and wildlife. The BP-511A battery is shared with the original 5D, 10D, 20D, 30D, and 40D — a large pool of compatible batteries on the used market. CompactFlash rather than SD provides higher durability at the cost of card interchangeability with modern systems.
On the used market the Canon EOS 50D is very affordable as a vintage Canon APS-C DSLR. Condition checks: shutter count via EXIF (rated 100,000 actuations), CF card slot contacts, BP-511A battery health (shared with original 5D, 10D-40D series), and no video to account for. No weather sealing. Compatible with all Canon EF and EF-S lenses.
