Tamron SP AFA022N700 150mm

The Tamron 150-600mm G2 delivers autofocus and stabilization in the 94th percentile, making it a top performer for the price. But build quality is a real weak spot, ranking in the bottom 3rd percentile, and long-term reliability is a common complaint. It's a high-risk, high-reward super-telephoto zoom.

This is where the G2 really shines. The Ultrasonic Silent Drive motor is quick and responsive, locking onto moving subjects without a lot of hunting. That 94th percentile AF ranking isn't just a number; it translates to a much higher hit rate when you're tracking birds in flight or a player running down the field. Pair that with the Vibration Compensation system, also in the 94th percentile, and you can hand-hold at 600mm with surprising confidence. Tamron claims 4.5 stops of stabilization, and in our testing, it delivers. Optically, the 21-element design with three ED elements and eBAND coating does a great job suppressing flare and ghosting, keeping contrast high even in tricky light. Sharpness at the long end is solid, which is exactly what you need from a super-telephoto zoom.

Stacked against something like the Sigma Contemporary 16-300mm, the Tamron is in a different league for reach and serious telephoto work, though the Sigma is far more versatile for everyday shooting. The Nikon Z 28-400mm offers a more modern, all-in-one range for mirrorless shooters, but it can't touch the Tamron's dedicated AF speed and stabilization performance at the long end. The Tamron's biggest fight is with its own reputation. The Canon EF-S 18-135mm is a great kit lens, but it's not even playing the same sport. If you need 600mm on a budget for a DSLR, the G2 is the obvious choice, provided you're willing to accept the risk on durability.

At $1319, the Tamron G2 offers a ton of reach and performance for the money. You're getting autofocus and stabilization that rival lenses costing twice as much. The price-to-performance ratio for wildlife and sports is hard to beat, especially when you consider the optical quality it delivers. It's a lot of lens for the price, but you have to weigh that against the documented build quality issues. If it holds up, it's a steal. If it doesn't, that value proposition crumbles fast.

The Tamron SP 150-600mm G2 lands in the 94th percentile for both autofocus and stabilization in our database, which is seriously impressive for a lens you can often find under $1400. That means its AF speed and vibration control are right up there with the best in class, making it a real contender for wildlife and sports shooters who need to nail the shot. The optical quality is a standout too, sitting in the 92nd percentile, so you're getting sharp results across that massive zoom range. But there's a catch, and it's a big one: build quality. It ranks in the bottom 3rd percentile, which is a red flag we can't ignore.

If you're rough on your gear or need a lens that can handle years of professional abuse in all weather, you should absolutely skip this one. The 3rd percentile build quality ranking isn't just a stat; it's a warning. Macro shooters should also look elsewhere, as its 58.1/100 score in that area is underwhelming. Anyone who prioritizes long-term reliability over peak performance per dollar will be better served saving up for a first-party option.

The Tamron SP 150-600mm G2 is a brilliant performer let down by a worrying track record for reliability. The autofocus and stabilization are genuinely best-in-class, and the image quality will make you smile. But that 3rd percentile build quality ranking and the low user sentiment score are impossible to overlook. We can only recommend this lens if you're willing to treat it with kid gloves and accept that it might not be a forever lens. For sheer reach and performance per dollar, it's fantastic. Just know what you're getting into.
