Tamron 17-50mm f/4 Di III VXD Review: A Bump in the Road for Tamron

Welcome back petapixel viewers it is chrisal here and today I’ve got an odd lens for you even odder than the Tamron 35 to150 because this is the brand new Tamron 17-50 F4 and no not for apsc like I assumed two or three times when I first heard the lens but actually for full Frame. So the 1750 might seem like a bit of a weird focal length on full frame.

Handling and Design

Now it’s a Tamron and I say that because it follows the exact same style and design that we’ve seen on the other Tamron lenses. It still feels nice and solid but more of a plastic housing keeps the weight down at 460 g. One thing that I will say we have a custom button here and Tamron software is excellent. The hood is classic and plastic but well built and well sealed despite the overall plastic feel.

Close-Up Capabilities

Two of my favorite things are when an ultra wide lens like this can also do really good close-up stuff to add the versatility for when I’m just out shooting about. This lens does a better job at 50 mm for close-up shots.


Right here on the side it’s a VXD, that means Tamron put their voice coil linear Motors in here and this is one of the faster lenses that I’ve tried that have the VXD. It’s very snappy, great for street photography.

Bokeh and Flare Performance

Having a look at example specular highlight shooting wide open at F4 actually not much cats eye in the corners, it’s very well controlled. The bokeh is nice and round but has some onion rings. Flare is well controlled with minimal loss of contrast. However, the lens does not produce amazing sun stars.

Video Performance

This lens excels as a video lens. It’s lightweight, doesn’t shift a lot of point of balance as you zoom and is very customizable with Tamron’s excellent software. The breathing performance is also pretty decent, making it a handy little video lens.


Shooting at 17 mm wide open at F4, the detail in the center is quite nice. Stopping down to f8 improves the performance slightly. However, in the corners at 17 mm shooting at F4, there is a lack of definition. At 50mm, the lens performs better in terms of sharpness.

In conclusion, the Tamron 17-50mm f/4 Di III VXD is a versatile and snappy lens with some drawbacks in sharpness and sun star performance. However, its close-up capabilities and overall video performance make it a strong contender for photographers and videographers looking for an all-purpose lens.
