The second-generation Tamron SP 150-600mm F/5-6.3 Di VC USD G2 offers better image quality, more features, faster auto-focus and more effective image stabilisation than the 2013 version, but the price has increased significantly, so it's not quite the out-and-out bargain that it once was.

The focal length range of this lens makes it most suitable for sports and wildlife photographers and birders, in particular, will find its fast autofocusing and effective stabilisation advantageous if they are looking for a long lens that can be used hand-held.

When Tamron introduced the first generation of the 150-600mm f/5-6.3 super telephoto lens, they were innovators in the third-party market. Never before had the barrier to entry for photography requiring a super telephoto lens been so low.

Tamron's update to its ultra-telephoto lens promises an enhanced capability with faster focusing and improved optical performance – so how do these new features fare? As any sports or wildlife photographer will tell you, an ultra-telephoto lens is an invaluable part of their kit bag.

Here we have an updated version of Tamron's already excellent 150-600mm zoom lens . With the promise of improved optical performance, faster AF, improved VC (Vibration Compensation) and many other minor improvements this looks to be a compelling upgrade. Let's see how it performs.

The Tamron SP 150-600mm F/5-6.3 Di VC USD G2 lens has some edge sharpness issues, but is an overall solid performer, especially when paired with an APS-C SLR.

Strong sharpness through most of range; Excellent stabilization system; Quick autofocus; Lockable zoom mechanism; Rotating tripod collar; Integrated Arca-Swiss foot; Weather-sealed design; Available for Canon, Nikon, and Sony SLRs

Weak edge performance at wide and telephoto extremes; Teleconverter use limits autofocus operation

Best lens in such price....Having fun with it...

Pros: For the price of this lens, it is an amazing lens! What a super value! Excellent for sports and wildlife. Let me say, I am truly impressed with the quality and speed of this lens. I shoot Canon, and have a 600 prime lens.

I tend to travel on the wide side when it comes to lens selection, so it was exciting to get a hold of Tamron's new super telephoto zoom-the SP 150-600mm f/5-6.3 Di VC USD G2 (Model A022). And what better way to give this big beauty a try than to take it on safari?

Still testing it but it looks great so far. I am happy with the reach and bouquet. Heavy, but not much. Good construction. I like that it comes with the tripod collar.
