Tamron 70-300mm f/4.5-6.3 Di III RXD Reviews
Very good value
I paid $450 for this lens but even at the MSRP of $550 it would be a great value. Autofocus works well and the images look sharp enough on my a7IV. The lens is very lightweight so I can bring it on outings when most super-telephoto lenses would be too cumbersome. I don't find the lack of stabilization to be an issue, with IBIS I'm able to shoot handheld at 300mm in moderate light and still get sharp images. The build feels solid enough, though the focus ring is somewhat stiff. I haven't needed the weather sealing yet but it's good to know it's there.
i love it!
It's a good peace for a good price
I'm very Happy with this zoom lens...
This zoom lens is very sharp and light...
Images are visibly better than those taken with Sony 70-300
I sold my Sony OSS 70-300 lens because I wasn't satisfied with most of the images it produced on my Sony A7iii. Even when shooting at 1/320 or faster, the sharpness and resolution were often disappointing. So far I'm really impressed with my new Tamron 70-300. It costs less than half the price of the comparable Sony. More important, images are sharp, the colors pop and the bokeh is pleasing. Sure, I wish the lens had image stabilization, a side control button and a locking feature, but I don't miss the added weight of the Sony. The Tamron is incredibly light yet it still feels solid and smooth. In fact, because the lens is lighter and slightly narrower than the Sony, it's easier to pull from my bag and switch lenses on the fly. That means I'll reach for it more often. I had also considered the Tamron 70-180 2.8, which is a sweet lens and certainly better for low light or in situations where you want to limit depth of field. But in the end, I wanted the longer reach of the 70-300. Overall, I'm very happy with my purchase. It's a nice complement to my Sony OSS 24-105 4.0, which is my primary lens, and Sony 16-35 4.0. I keep a Sony 35 mm prime 1.8 for low-light situations.
Lightweight zoom lens for sports.
A high quality zoom lens for outdoor sports. Lightweight and fast focus. Very reasonable price.
Disappointing focus performance
I can't tell if I got a defective unit or if the lens is just mediocre. Autofocus was unreliable, especially at the midrange of the zoom. At some settings, the focus was good across the frame. At other settings, the focus was uneven across the frame. Sometimes it was sharper at the edges than at the center. It's not a lens I could rely on. I have other Tamron lenses that I like, but not this one.
Surprisingly good lens.
Excellent value for the money. Yes, it's a little slow, particularly on the super-telephoto end, but it was surprisingly sharp. Maybe I set my expectations really low because of the price, but I am quite pleased with the quality of the photos I've gotten from this lens.
