Canon EOS 1D Mark IV

The Canon EOS-1D Mark IV, launched in late 2009, was a professional-grade DSLR that earned a strong reputation among wildlife photographers. Its rugged magnesium alloy body and excellent weather sealing made it reliable in harsh field conditions. The camera featured a 16.1MP APS-H CMOS sensor and dual DIGIC 4 processors, enabling shooting speeds of up to 10 fps. Its groundbreaking 45-point autofocus system with 39 cross-type points was particularly impressive for its time, offering excellent tracking capabilities for birds and wildlife. With a native ISO range of 100-12,800 (expandable to 102,400) and excellent low-light performance, it remained a workhorse for wildlife photographers throughout the early 2010s.
