Lenses for full frame cameras in the range of around 100-400mm hit an extremely useful point in the focal length range. Birding, general wildlife, sports and portraiture all cry out for these lenses so an alternative to the generally expensive marque optics is always welcome. The Tamron 100-400mm f/4.5-6.3 Di VC USD lens is reviewed here using the Canon 5D SR body. Alongside this, we have the optional Tamron Tripod Mount M that is specifically designed for the lens and is included in the review.
Handling and Features
The lens is relatively compact for its specification, helped by the modest maximum aperture, appears well made and operates very smoothly. It weighs in at 1115g without caps or hood, 1180g with hood and 1320g with hood and tripod mount. Now although it is quite possible that higher end, solid DSLR mounts will happily carry the weight of the lens, it is arguable that it is much better to use the ARCA-SWISS compatible tripod mount.
