Olympus m.ZD 75-300mm f/4.8-6.7 zoom lens

  • Olympus has created a compact, hand holdable super telephoto zoom lens for the Micro Four Thirds system which is capable of up to 600mm supertelephoto field of view in 35mm terms without compromising significantly on sharpness.
  • it is best used on a camera such as the Olympus OM-D E-M5 camera fitted with the HLD-6 grip for better ergonomics, and of course image stabiliser which reliably allows hand holdable shutter speeds down to 1/160th sec at the 300mm end.
  • 150-600mm in 35mm terms
  • 58mm non-rotating filter thread
  • metal lens mount
  • 7 rounded blades

Panasonic Lumix G Vario 100-300mm f/4-5.6 Mega OIS

  • version ii announced in Jan 2017 offers better weathersealing, and smoother aperture variance when zooming
  • both lenses can support Dual Sync IS (version I needs firmware upgrade)
  • 200-600mm in 35mm terms
  • Mega OIS (2-3EV) image stabiliser
  • fast near silent AF
  • 67mm non-rotating filter thread
  • 7 rounded blades
  • metal mount
  • closest focus 1.5m
  • 520g
  • $599
  • it seems that best results are at the 100-220mm range with shots at longer focal length being much less sharp, although camera shake is likely a major factor at such high magnifications.
  • the IS apparently only gives 1-2 stops advantage
    • CA and vignetting very well controlled
    • “nice bokeh”
    • “While this lens is obviously not in the same class as the primes and high-grade zooms that we have reviewed so far, it is actually pretty amazing for a superzoom.”
    • “The lens also earns our admiration for fast focusing on the equally new DMC-GH2, even at the 600mm equivalent end of the zoom range in low-light conditions”
    • not as sharp as the Olympus lens?
    • great value for money when used in average light, shot at f/7.1, ISO 1000 for birds on branches, etc
    • main issues are significant lateral CA and AF issues in low light
