Tamron SP 150-600mm G2 AFA022N-700

The Tamron SP 150-600mm G2 is a super-telephoto zoom for Nikon F-mount that delivers outstanding reach, best-in-class stabilization, and fast autofocus at a reasonable price. It's heavy and struggles in low light, but for wildlife and outdoor sports shooters, it's a top pick.

Optically, this lens is a standout. In our database, it sits in the 93rd percentile for optical quality among all lenses, which is seriously impressive for a zoom with this much range. The three LD elements and Tamron's eBAND coating do heavy lifting to keep chromatic aberration and flare under control, even when you're shooting backlit subjects at 600mm. Sharpness is excellent through most of the range, though it does soften just a touch at the very long end, which is typical. The Ultrasonic Silent Drive autofocus motor is another high point, landing in the 94th percentile for AF performance. It snaps onto subjects quickly and tracks moving wildlife without a lot of hunting, though it's not quite as instantaneous as some high-end native glass. The stabilization is best-in-class, hitting the 95th percentile, which is a lifesaver when you're at 600mm and the light starts to dip.

The Tamron G2 goes head-to-head with a few different options depending on what you shoot. The Nikon NIKKOR Z 17-28mm f/2.8 and Sigma Contemporary 18-50mm f/2.8 DC DN are completely different beasts, standard zooms for mirrorless systems, so they're not direct competitors for a super-telephoto. The real alternative in the F-mount world is the Nikon 200-500mm f/5.6E. The Nikon gives you a constant f/5.6 aperture, which is a real advantage for low light, but you lose 100mm on the long end and 50mm on the wide end. The Tamron's autofocus and stabilization are slightly better in our testing, but the Nikon feels more solidly built. If you're on a Sony DSLR body (yes, the A-mount still exists), the Sony E 18-135mm f/3.5-5.6 OSS isn't even in the same conversation for reach. For sheer focal length per dollar, the Tamron is hard to beat.

Pricing on this lens is all over the map, with a spread of over $38,000 across vendors, which is frankly absurd and likely driven by third-party marketplace weirdness. The realistic street price for a new copy sits around $1,989, and at that level, it's a fantastic value for the reach you get. For comparison, a first-party Nikon 200-500mm f/5.6 costs more and gives you less range. If you can snag one from a reputable seller like Newegg at the lower end of that spectrum, you're getting a lot of lens for the money. Just double-check you're buying the USA model if that 6-year warranty matters to you.

If you're hunting for a super-telephoto zoom that won't completely destroy your bank account, the Tamron SP 150-600mm f/5-6.3 Di VC USD G2 (often just called the G2) is probably on your radar. This is a full-frame lens for Nikon F-mount shooters who need serious reach for wildlife, airshows, or backyard birding. The 150-600mm range gives you a ton of flexibility, and the constant f/5 max aperture at the wide end is about as good as it gets in this class without spending five figures. At nearly 2kg, it's a chunky piece of glass, but the built-in Vibration Compensation (rated for 4.5 stops) means you can actually handhold it in decent light without everything turning into a blurry mess.

Skip this lens if you primarily shoot portraits, indoor events, or anything that demands a fast aperture and beautiful background blur. The bokeh is a weak spot, and the f/5-6.3 max aperture will frustrate you in low light. If you need a lens for dimly lit weddings or concerts, look at a 70-200mm f/2.8 instead. Macro shooters should also look elsewhere, the 2.2m minimum focus distance and mediocre close-up performance won't cut it for detailed small-subject work.

Should you buy the Tamron SP 150-600mm G2? If you're a Nikon F-mount shooter who spends weekends at the track, in a bird blind, or chasing your kid's soccer games from the sidelines, the answer is a pretty easy yes. The reach is phenomenal, the stabilization lets you leave the tripod at home more often than you'd think, and the autofocus keeps up with fast action. Just know what you're signing up for. This is not a lens for dimly lit gymnasiums or indoor events. The slow aperture means you'll be cranking your ISO once the sun starts to set, and the bokeh won't win any awards for creamy backgrounds. But for daylight telephoto work, it's one of the best values out there.
