Last month, Tamron announced the 35-100mm F2.8 Di III VXD, a full-frame zoom lens that focused on offering a fair amount of reach and a fast aperture while still being compact and lightweight. We've had the chance to shoot with it a bit to get a feel for what it's like to use and how it performs.

The first thing that stands out about this lens is the weight. If you're used to shooting with a 24-70mm F2.8, this lens is noticeably smaller and lighter than most full-frame options. That's not to say that the focal length ranges are particularly comparable – they're not, especially on the wide end – but it's a good frame of reference.

The lens is quite small and light, which would make it a good pairing for some of the more compact full-frame bodies. It also includes a customizable mode switch and function button.

Despite the light weight, the lens feels solidly built. To my hands, the materials and design of the zoom and focus rings actually feel a touch nicer than other recent Tamron lenses that I've tried. While most wouldn't consider a $900 to be cheap by any stretch, it feels more premium than its price tag might suggest.

Paired with an a7R V, the autofocus was very snappy, and it never felt like the lens was holding back the camera.

The lens extends a bit when zooming in, but not enough to throw off the balance or meaningfully change the center of gravity.

While this isn't a full review of its optical quality, I was pleased with how sharp the samples I got with this lens were, even when I was shooting wide-open. As we've seen with many recent F2.8 zooms, especially ones that focus on size, it has a fair amount of vignetting at F2.8 and even still some at F4, but it largely clears up by F5.6. I also find the out-of-focus rendering to be perfectly fine; it's not distracting, and the falloff is pleasant enough, though if you inspect the specular highlights in the bokeh, there is some cats-eye effect.

Toward the edges of the frame, you'll start to see some cat's-eye bokeh. (Note that the lights on the left edge of the frame aren't being distorted by the glass cups.) Sony a7R V | Tamron 35-100mm F2.8 | 100mm | F2.8 | 1/100 sec | ISO 500

In the past few years, we've seen companies playing focal length ranges, such as Sony's 20-70mm F4 and 24-50mm F2.8, so it's interesting to see someone experimenting in the other direction. However, we suspect many people who learned photography after the era of the 35-70mm might feel restricted by a lens that only barely dips its toe into the wide-angle range, especially if they were trying to use it as an all-around standard zoom.

However, I found I really enjoyed working with this zoom range, especially given the size and weight of the lens. I could easily see being happy with just it and a wide (or maybe even ultrawide) prime, though your mileage may definitely vary, especially if you're someone who often finds themselves wishing they could go wider than 24mm, rather than someone like me who often wishes they could reach past 70mm. In that respect, I prefer this to Tamron's own 28-75mm F2.8, as it feels like I get more for giving up something on the wide end (though obviously it's a greater sacrifice).

For most people, though, this lens might make more sense as a complement to, rather than a replacement for, a standard zoom, especially if their standard zoom is a variable-aperture kit option. It offers F2.8 and some of the most popular portrait focal lengths with more flexibility than a prime, and without the need to carry around a giant piece of glass like a 70-200mm.

Thank you to LensRentals for loaning us a Sony a7R V to shoot this lens gallery, and to Tamron for loaning us the lens. All images were processed using our standard lens workflow in Capture One, with the manufacturer's distortion correction applied but no vignetting correction. Before correction, the images have some minor pincushion distortion, but we wouldn't consider the profile to be an essential part of the lens design if you prefer not to use it, or your preferred software does not support lens corrections.

Home base: Delhi, India

Favorite camera and lens: Canon EOS R5 II paired with the EF 500mm F4 IS II – a powerful combination Jagdeep relies on for capturing distant wildlife and dramatic animal behavior in the field.

Typical photo scenes: Wildlife photography, especially large mammals and wetland birds in national parks and open natural habitats.

"I started photographing in the early 1980s, and over the years it has grown into a lifelong passion for observing and documenting wildlife."

Jagdeep is a wildlife photographer who enjoys working with small groups of like-minded friends. Most of his photography takes place in India’s national parks, where he spends a lot of time sitting still, patiently watching and waiting for the right behavior or interaction with animals to unfold.

What's in Jagdeep's bag

• Primary cameras: Two Canon EOS R5 II bodies
• Lenses: RF 24–105mm F4 for versatility, RF 70–200mm F2.8 VCM for action and medium telephoto work, and a 100–400mm F5.6 for additional reach. For distant wildlife, Jagdeep relies on the EF 500mm F4 IS II, often paired with 1.4x and 2x teleconverters.
• Support and accessories: A beanbag is an essential part of his kit, especially when shooting from vehicles in wildlife reserves. He also carries a close-focusing tube to allow tighter framing when subjects approach closer than expected.
• Camera bags: Jagdeep prefers backpack-style camera bags, typically from Lowepro, Tamrac or Think Tank. For bird sanctuaries and longer walks, he uses a larger Tamrac backpack along with a tripod and gimbal head to support long lenses. When photographing from a vehicle, he relies on a beanbag for stability.
• Other Essentials: A sun hat is always packed for field protection, and gloves come along during the cooler winter months.

What other gear makes a difference?

"I like to keep my setup fairly simple in the field, but a few accessories are always important. A beanbag is something I rely on often, especially when photographing wildlife from a vehicle, as it provides quick and stable support for long lenses. I also carry a close-focusing tube, which allows me to get tighter shots when an animal or bird comes closer than expected.

Other than that, I usually pack a sun hat to deal with the intense sunlight during long hours, and gloves during the winter months when mornings in the field can be quite cold."

What has been one of your most amazing moments out in the field?

While India remains his primary shooting ground, Jagdeep also travels to Africa, photographing wildlife in places like the Masai Mara, Amboseli and Tsavo. One of his most memorable moments occurred at Keoladeo National Park in Bharatpur.

"Once, I went to Keoladeo National Park, Bharatpur, India, to photograph a nesting Sarus Crane. A Bluebull happened to venture close to Sarus's nest, the crane opened its huge wings and attacked the bull from behind. Since I liked to shoot animal behaviour, I pressed my continuous shutter, and the image I captured was unbelievable; it was 'Pegasus'."

Jagdeep's advice for other photographers

"Good subjects are hard to find. If you come across one, don't give up easily. Go for a couple of exceptional frames rather than hundreds of good frames."
