You really don't want to shoot from a tripod, and larger/longer lenses can be very tiring to hand-hold all day.Godox AD400Pro. These are all huge benefits for aviation photography. It's cheap, it's super light weight, and it stunningly sharp. Before settling on one of the 100-400 lenses, consider the Nikon 70-300 AF-P VR.
Sigma is producing excellent primes and Tamron seems to have better reviews on zooms.Submit any original pbotograph(s) taken with Tamron lenses or Bronica cameras. The Sigma is 699 new usd with a dock, the Tamron used about 620 and adding a tap in will be about the same as a new Sigma or 799 for a new Tamron no tap in. FeaturesI think the 100-400 will be the best. The upside is that It’s much less of a strain for prolonged periods of handheld shooting, and easier to simply carry around. As such, it tips the scales at 1,135g for the Canon-mount edition, and 1,115g for the Nikon-fit version. Favorite compare.Going toe to toe with Sigma’s already well-established 100-400mm ‘Contemporary’ lens, this Tamron 100-400mm for Canon and Nikon DSLRs reins in the amount of super-telephoto reach, enabling it to be a more manageable 199mm in physical length and barely more than half the weight.
Tamron 100-400mm f/4.5-6.3 Di VC USD for Nikon (Black) at Walmart for $714.97Like most super-telephoto zooms with a variable rather than ‘constant’ aperture rating, the Tamron has a fully internal focusing mechanism, so the front element neither rotates nor extends during focusing. VC (Vibration Compensation) optical stabilization system The Sigma is 699 with the USB dock (new) and Tamron 639 Used or 799 new. The Tamron is a little faster, 4.5, but not much and accepts a tripod collar (not a big deal). I just have to decide between Tamron or Sigma 100-400mm. Features a fully internal focusing mechanismTest: Canon, Sigma and Tamron 70-200 (and 100-400) The 70-200 f/2.8 zooms are good lenses for sport and portrait photos for nature photography, 200mm usually is a bit too short: nevertheless, I was curious to see how the Tamron and Sigma 70-200 2.8 performs in comparison with the much, much more expensive Canon 70-200 IS.Thank you.
Build quality and handling There’s also a TAP-in Console (£79/$59)for applying fine-tuning and firmware updates, and a typically pricey tripod mount ring (£110/$129), but at least the latter is directly Arca-Swiss compatible. So while the lens is reasonably compact for stowage and carrying around, it’s still pretty big when shooting at or near the longest zoom setting.Optional extras include an own-brand Tamron 1.4x tele-converter, the use of which maintains the availability of autofocus in DSLRs that support AF at an aperture of f/8.
AF system is super-fast and consistently accurate The autofocus range limiter is cleverly implemented, its ‘Limit’ position enabling the opposite sector of the autofocus range to be locked out, depending on whether a short of long focus distance is in use when the switch is activated. Additional switches are on hand for the dual-mode VC system, and for AF/MF/Limit. Our review sample didn’t suffer from any zoom creep whatsoever, but a zoom lock switch is fitted nonetheless. The main section of the outer barrel is made from magnesium alloy and feels very robust, and the lens features weather-seals and a fluorine coating on the front element, which repels moisture and grease, and eases cleaning.Handling is very refined, with a smooth-action, precision feel to the zoom and focus rings.
It makes a huge difference in getting consistently sharp shots, especially on APS-C format DSLRs, where the ‘effective’ zoom range is boosted to 160-640mm (Canon) or 150-600mm (Nikon).Contrast is excellent throughout the entire zoom range, even when shooting wide-open, as is sharpness across most of the frame. Tamron’s VC system is typically effective, giving a benefit equivalent to around four f/stops. It’s also whisper-quiet, which can be a bonus when photographing wildlife.
VerdictTamron’s updated G2 (Generation 2) lenses have really impressed us recently, especially its 70-200mm f/2.8 zoom, which is simply fabulous. Color fringing is minimal throughout the zoom range, and the touch of pincushion distortion at 100mm only gets a little worse at medium to long zoom settings. However, when shooting on a full-frame rather than an APS-C format camera body, there’s a more noticeable drop in the Tamron’s corner-sharpness.
