World-renowned Canon EF-series lenses are the perfect complement to the EOS-1Ds Mark III. Choose from over 50 different lenses, ranging from 14mm wide-angle and 600mm super telephoto lenses to Ultra Low Dispersion (UD) and Super UD fluorite lenses — all tack sharp even when shooting wide open. You can even use Canon fish-eye lenses and obtain the same dramatic impact as 35mm film cameras thanks to the full-frame CMOS sensor. Rounding out the lineup are Canon IS (image stabilization) lenses, available in both zoom and fixed focal lengths, which noticeably reduce blurred imaging caused by camera shake. Canon’s exceptional optical know-how, precision engineering techniques and outstanding innovation also provide such advances as whisper-silent operation via ultrasonic motors and innovative aspherical lens technology. Note: EF-S lenses cannot be used with the EOS-1Ds Mark III.
