These lenses give big telephoto reach, but some are more powerful than others

-

For Nikon cameras, a longstandi­ng favourite supertelep­hoto zoom range is 80-400mm. The original Nikon AF 80-400mm f/4.5-5.6d VR was launched back in 2000 and eventually replaced by the AF-S 80-400mm f/4.5-5.6g ED VR in 2013, as featured in this Big Test. Nikon’s first and so far only Z-mount super-tele zoom has a similar range of 100-400mm, as do the more budget-friendly Sigma and Tamron F-mount lenses on test.

Naturally, if you mount a 100-400mm lens on a DX camera, the APS-C format crop factor boosts the ‘effective’ zoom range to 150-600mm, without the one or two f-stop reduction in aperture width of using a 1.4x or 2x teleconver­ter respective­ly. All of the lenses on test are FX (full-frame) compatible, and all but the Nikon Z 100-400mm are designed for F-mount DSLRS. However, these can also be used on mirrorless Z system FX and DX cameras via an FTZ or FTZ II mount adapter. The only caveat is that early examples of the Tamron 100-400mm and 150-600mm lenses in the group will need a firmware update to V3 and V2 respective­ly.

For extending your telephoto reach even further, Nikon offers the AF-S 200-500mm f/5.6e ED VR, while Sigma and Tamron have supersized their longest zooms to a range of 150-600mm. On a DX body, the effective zoom range of these lenses gets bumped up to 300-750mm or a huge 225-900mm. You can use the lenses here with the same make of teleconver­ter but, if you’re starting with an aperture of f/6.3 at the long end, a 2x tele-converter will narrow it to f/13.

For tracking the action in sport and wildlife photograph­y, fast autofocus (AF) is needed. These lenses oblige with rapid and quiet ring-type ultrasonic AF systems, apart from the Nikon Z 100-400mm, which features super-fast and near silent AF based on dual linear stepping motors.

Effective image stabilizat­ion is crucial when shooting handheld – or even with a monopod – at such long focal lengths. Sure enough, all of the lenses on test feature optical stabilizat­ion, competing systems being Nikon VR (Vibration Reduction), Sigma OS (Optical Stabilizer) and Tamron VC (Vibration Compensati­on).
