For those who think about that it is extremely related in dimension and weight to a typical 70-200mm f/2.8 or the extra typical 100-400mm zoom, although, with a lot much less lens swapping wanted as a result of wider 50mm focal size, then this lens all of the sudden turns into much more fascinating.
Whereas you need to use it on a smaller APS-C physique just like the Sony A6000 collection of cameras, it will not steadiness notably nicely and the equal focal size can even change to 75-600mm (which can be a profit).
As demonstrated by the product photographs, it is a a lot better match for a extra skilled full-frame digicam just like the Sony A7R IV that we examined it with, the place it simply feels higher balanced and extra “at dwelling”.
Construct high quality is superb, regardless of Tamron historically providing lenses on the cheaper finish of the market. The Tamron 50-400mm F/4.5-6.3 Di III VC VXD feels very stable in your hand, with the outer barrel constituted of high-grade plastics as in all of their current lenses.

The 50-400mm F/4.5-6.3 Di III VC VXD encompasses a Lock change which fixes the lens at its 50mm setting and prevents it from extending when it is pointed downwards, though we did not actually discover any important zoom creep.
There’s one focus management button, a characteristic that’s discovered on many different Tamron zooms. The operate of this button will be customised by way of the Customized change, which affords 3 presets which are configurable utilizing the Lens Utility software program.
The opposite important new characteristic is the USB-C Connector Port, which lets you replace and customise the lens immediately utilizing the Tamron Lens Utility software program, relatively than by way of a digicam physique.
We’re just a little involved that this port is uncovered, although, and subsequently not shielded from the weather, though Tamron have assured us that it’s totally waterproof.
Within the customisation choices, the course and velocity of focus will be modified. The main target ring can be utilized for aperture as a substitute of handbook focusing, whereas the main target maintain button will be customised for a preset focus level for video so as to pull focus from one to the opposite at a chosen velocity.
A brand new Focus Limiter management characteristic can be now obtainable for this lens within the TAMRON Lens Utility software program.

The Tamron 50-400mm F/4.5-6.3 Di III VC VXD options the most recent high-speed VXD (Voice-coil eXtreme-torque Drive) which is alleged to be twice as quick because the older RXD motors. It additionally permits for nearly silent auto-focusing, making it well-suited to video use.
In use, we discovered the VXD focusing system to be whisper quiet and really quick with the lens mounted on a Sony A7R IV digicam.
Importantly, the lens is totally suitable with the “Direct Handbook Focus (DMF)” system characteristic of Sony cameras that permits the person to immediately change between autofocus and handbook focus.
Focusing is totally inner however zooming isn’t, with the size of the lens step by step rising by as much as a most of seven.5cm as you zoom from 50mm to 400mm.

The VC Mode change controls Vibration Compensation, with three completely different choices – Off, 1 (customary) and a couple of (dynamic).
Be aware that turning off vibration compensation by way of the lens routinely disables the in-camera IBIS, and turning off IBIS by way of the digicam physique routinely disables the vibration compensation by way of the lens, even when the change is about to mode 1 or 2.
The lens is provided with plastic lens caps and a plastic petal-shaped lens hood (HA067) which twists and lock into place – there isn’t any lens bag included.
