Sigma 300-600mm f/4 Hands-On in the Wild – A Kingfisher Adventure with Olle Nilsson

Share

Wildlife photographer Olle Nilsson took the brand new Sigma 300-600mm f/4 DG DN OS Sports Lens out for a two-day field test, aiming to capture lightning-fast kingfishers in action. Key highlights from the video:

  • The constant f/4 aperture delivers exceptional subject separation and low-light performance
  • Sharpness is superb across the 300-600mm range, paired with a Sony A1 for 50MP cropping flexibility
  • Lens is large (~4kg), but surprisingly manageable with its internal zoom and balance
  • Compared to the Sony 200-600mm f/5.6-6.3 G OSS, the Sigma delivers much stronger subject isolation
  • Faster and more versatile than using a 300mm f/2.8 GM with teleconverter setup in static positions
  • Ideal for hide-based or tripod work – less suited for mobile “sneaking” shoots due to weight

Olle also tested the lens on a Leofoto PG-1 gimbal head and a carbon fiber tripod, which helped stabilize the heavy setup for hours in the field.

His final verdict? While it’s a heavy investment, the Sigma 300-600mm f/4 delivers pro-level results at nearly half the price of a 600mm prime. For those who shoot from a fixed location and value flexibility, sharpness, and beautiful background separation – this is one of the best lenses available.

For those interested in stunning wildlife imagery and want a telephoto workhorse that rivals prime lenses in sharpness and speed – this Sigma might just be the dream lens.

Either way, better safe than sorry — if you’ve been eyeing a Sony camera or lens, now’s the time to grab one while the deals are still on!

Here is the total saving rebates+cashback on cameras:
