Desiontal 420-800 420-800mm

★★★★☆ 4.1 (386)

Its 420-800mm zoom range on a full-frame Canon EF mount provides extreme reach for distant subjects like wildlife and the moon at a very low entry cost. The fully manual focus and aperture design, combined with UMC-coated optics, forces a deliberate shooting process that builds technical skill while delivering sharp images with notable background bokeh. This lens is best for budget-conscious hobbyists wanting to experiment with super-telephoto photography on older Canon DSLRs without relying on autofocus.

  1. Q1 202667/1003.7★3 avis

    Buyers gave mixed feedback: one praised the lens for moon photos and long distances, but another said it didn't fit the camera as stated.

    • Works well for moon photography and long-distance shots.
    • Does not fit the camera as advertised.
  2. Q4 202588/1004.6★5 avis

    Buyers praised build quality and value, but noted the fully manual operation requires practice and a tripod; minor color shift at long distances was mentioned once.

    • Fully manual lens: no electronics, must hand-adjust focus/aperture; tripod recommended.
    • Excellent build quality and fit; no looseness, produces good images.
    • Good value for hobbyists but heavy; requires tripod and practice.
    • Color shift at long distances; not true to life.
  3. Q3 202560/1003.8★5 avis

    Buyers praised the lens for astrophotography and travel use, but several found manual focusing difficult and the build quality lacking.

    • Good for astrophotography and travel due to lightweight design and versatile zoom range.
    • Manual focus is hard to use smoothly, especially for beginners.
    • Heavier than expected, with build quality concerns mentioned.
    • Affordable and decent for amateurs, but not without compromises.
  4. Q1 202433/1002.0★3 avis

    • Manual focusing is extremely difficult, especially for sun photography.
    • Lens is unusable without a sturdy tripod.
    • One reviewer received a lens with a broken camera adapter.
    • Decent image quality for under $100, exceeding expectations at that price.
