3.5X High-Definition Telephoto Converter for Canon EOS 1Ds — Fits 49/52/55/58/62/67mm Filter Threads

A compact 3.5X telephoto converter engineered for DSLR use and optimized for the Canon EOS 1Ds. This auxiliary telephoto optic mounts in front of your existing lens to increase magnification by 3.5X while remaining lightweight and travel-friendly. Optical performance is boosted by three extra-low dispersion glass elements that suppress both longitudinal and lateral chromatic aberration in sharp and out-of-focus areas, reducing purple fringing and ghosting throughout the aperture range. The multi-coated optical glass improves light transmission and cuts reflections; the front accepts 72mm filters for easy creative control. Designed with a shorter flange distance for DSLR compatibility, the unit delivers improved sharpness in a more compact form than many alternatives. Ideal for wildlife, sports, and portrait work, it provides clear, detailed results without extensive post-processing. Physical specs: just 2 inches in height and 6.4 oz in weight (without the hood). Includes: Lens, Pouch, Stepping Rings, Lens cap, Bottom Cover.
