If you’re in search of a 100-400mm lens, it’s likely you’ve heard about why this focal range is so treasured. I’ve used dozens of lenses during my career, but none have won me over like the versatility of the 100-400 models.
Canon EF 100-400mm L IS II USM
★★★★★ (5/5)
It provides exceptional image quality, fast and accurate autofocus, and superb image stabilization in a durable, weather-sealed body. Its optics deliver razor-sharp results across the zoom range, while the smooth zoom ring and advanced IS make it ideal for wildlife, sports, and travel photography. It’s the perfect blend of reach, sharpness, and professional reliability.
It offers the perfect middle ground, being suitable for both closer wildlife, sports, and action shots, as well as wide enough for taking environmental portraits or landscapes with terrific sharpness. Such a lens is my go-to choice on photoshoots when I’m not in the mood to mess around with several bulky primes.
However, picking the optimal 400 mm lens can be tricky. The market is full of models that are made by different manufacturers, vary in compatibility, and cover a wide range of price points. During my career, I’ve used such lenses for all manner of photoshoots, from weddings to safaris, so I understand how puzzling it can feel to look at all the available options.
Remembering that hesitation inspired me to prepare this guide. I didn’t judge lenses solely by their technical specifications or marketing talking points. I talked to my fellow photographers and clients, browsed Reddit and specialized forums, studied reviews, and tested dozens of 100-400mm lenses myself before putting together this final shortlist:
When I choose a 100 to 400mm camera lens, here are the things that matter most to me:
The main reason why 100-400 is considered the “perfect middle ground” in terms of focal range is that it can accommodate most scenarios with telephoto lenses without making you commit to bulky, fixed long prime models.
I bring a 100-400mm lens to weddings, wildlife shoots, motorsport races, and even portrait sessions when I need to switch between a compressed look and separating the subject from the background without getting too close.
Shutter speed recommendation. Begin with 1 / (focal length) when shooting in handheld mode. If you set it to 400mm, then choose 1/400s or faster for dynamic subjects. If your camera has top-tier image stabilization, then you can try a lower speed, but be sure to test it before the actual photoshoot.
For flying birds. Set the camera to continuous AF (AF-C/Servo), and use a high framerate mode, and give your bird photography lens some breathing room. I also suggest setting a smaller AF area if the camera supports such a feature. Train our panning skills and follow the subject with your entire body, not only your wrist.
For weddings and candid shots. Stay zoomed out a bit (200-300mm) to keep more of the scene in shot, and zoom in to isolate the subject if necessary. The compression at 400mm is very impressive, but tends to obscure most of the environment.
Employ a monopod for longer events. It provides convenient mobility with load support, particularly if the photoshoot lasts for hours.
Teleconverters. They can be handy, but check the autofocus performance since many lenses can’t handle 1.4x or 2x converters properly. My experience shows that the Canon EF 100-400 lens offers better performance at 1.4x than cheaper alternatives. Be sure to read up on the compatibility of your lens before committing to a TC.

This is arguably the best Canon 100-400mm lens according to Reddit, so I was very interested to see if it deserves its reputation. I used it for about two weeks while tackling wildlife outdoor sports and engagement photoshoots. I paired it with my Canon 5D Mark IV while also doing a quick test with the 7D Mark II to check its performance on a crop model.
I instantly appreciated the balanced handling. While it’s rather heavy, the size is still suitable for handheld shots, particularly when you juxtapose it against 400mm prime lenses. It’s a reliable representation of the Canon L-series – sturdy, has weather sealing, and can handle both dusty fields and rainy woods. The zoom ring offers a bit of resistance, as the manufacturer has abandoned the push-pull design, which is a decision I support wholeheartedly.
The best feature that makes this model a good lens for wildlife photography is the image stabilization (IS). I set it to 1/160s at the full 400mm and managed to snap photos with impressive sharpness even in handheld mode. Autofocus is super quick and reliable, managing even to capture birds in flight.
When I was working at a wedding, this lens enabled me to keep my distance while snapping candid pictures without intruding on the couple. If you draw a comparison to the Canon RF 100 - 400mm lens, this model feels more professional. It’s bulkier but also offers superior sharpness and speed.

Aperture: f/4.5–5.6 | OSS: Optical SteadyShot | Mount: Sony E | Focus motor: Dual Direct Drive SSM | Weight: 1395g | Filter thread: 77mm
My coworker believes this Sony lens is the best 100-400mm option on the market. I paired it with a Sony A7 IV and A9 II, primarily taking sports and wildlife photos, which are always a strong point for Sony cameras. It also helped me handle an outdoor engagement photoshoot that included several long-distance portraits.
This lens is pleasantly compact considering its focal length. It’s not as heavy as the Canon EF 100-400mm II, which can be a huge deal if you’re going on a hike or are constantly on the move during a sports event. The zoom ring is smooth yet firm, ensuring you won’t change the setting by mistake when following dynamic subjects.
Autofocus is incredibly fast. When paired with an A9 II, Sony’s real-time Eye AF made focusing on subjects a breeze, even when I was taking pictures of birds in flight. When juxtaposed against the Sigma 100-400mm, this model is superior when it comes to autofocus tracking and image stabilization, particularly at the far end of the zoom.
For portraits, I think 100-200mm is the optimal range, providing efficient compression, while 300-400mm enables me to take photos of authentic moments without getting too close to the subjects. The only downside is that the bokeh isn’t as creamy as several other primes can offer, meaning you’re sacrificing artistic blur for the sake of flexibility.
“If you haven’t tried Sony’s OSS, try various stabilization modes for panning and stills. Also, when handholding at 400mm, I tuck my elbows in and rely on the strap to minimize shaking.”

Aperture: f/5.6–8 | IS: Optical Image Stabilization | Mount: Canon RF | Focus motor: Nano USM | Weight: 635g | Filter thread: 67mm
This Canon lens is often highly praised on both Reddit and Amazon, particularly in the budget-friendly segment, so I wanted to give it a proper go. I paired it with my Canon R6 and R7 during multiple photoshoots: a soccer game, a bird-watching trip, and a simple family shoot in a park.
I instantly liked how lightweight this 100-400 Canon lens is, particularly when compared to the other Canon lens mentioned before. You can conveniently place it into your backpack without having to use a bulky tripod. If your main goal is travel and spontaneous photoshoots, the compact build of this lens alone makes it a top candidate.
The picture quality is also impressive considering the relatively low price. It lacks the sharpness of the EF L model at 400mm, but it’s still capable of satisfying all your social media, print, and client needs as long as you don’t need to do large-scale prints. The AF system is fast and efficient, even managing to keep up with unpredictable bird movements.
If this is your first time getting a telephoto zoom, you’ll find this lens to be very forgiving and easier to handle. However, if you need to take professional photos in fast-paced environments, the slower aperture might feel like a significant drawback.

Aperture: f/4.5–5.6 | VR: Vibration Reduction | Mount: Nikon Z | Focus motor: Multi-Focusing STM | Weight: 1435g | Filter thread: 77mm
This Nikon lens is the go-to choice for most photographers who shop on Amazon, so I was very excited to test it. I dedicated an entire week to using it on a Nikon Z8 and Z6 II, taking pictures of everything from animals and birds to local sports events. My goal was to see if this is really the best 100-400mm lens Nikon has to offer, and it managed to meet all of my expectations.
It offers an impressive reach while remaining pleasantly balanced. It’s more lightweight compared to the Canon EF 100-400mm II and a bit smaller, which is especially important if you’re going on a multi-hour hike to take wildlife photos.
The zoom ring offers perfect smoothness with just the right amount of resistance to prevent accidental changes. The VR functionality is also fantastic, allowing me to take crisp photos at 1/200s at 400mm, which is a small miracle at this focal length.
This 100-400 lens also provides terrific edge-to-edge sharpness, capturing most of the detail and color even at 400mm. The AF system is quick and reliable, particularly when paired with the Z8, although it loses some of its speed in low light compared to Sony’s 100-400mm lens. It’s a minor drawback, but it can be noticeable if you’re shooting a sports game under stadium lights.

Aperture: f/5–6.3 | OS: Optical Stabilization | Mount: Sony E / L-Mount | Focus motor: Stepping Motor | Weight: 1160g | Filter thread: 67mm
My coworker recommended I use this Sigma lens as a cheaper alternative to premium Canon 100-400 lenses. I tried it out for multiple days with my Sony A7 IV, primarily taking wildlife, soccer, and urban travel photos to check how well it can deal with fast action and slower scenarios.
I instantly liked how portable this lens is. It’s more lightweight and slimmer than the other models featured above. If you’re a travel photographer or simply don't have enough space in your gear bag, this 100 x 400 lens is a great choice. I can conveniently pack it into my backpack while also avoiding getting a lot of attention when taking photos in public.
The AF system is solid but inferior to most competitors. Unlike the Sony FE 100-400mm, it has a bit of a lag when following unpredictable movement like flying birds. That said, it’s perfectly capable of tracking slower subjects, like athletes on a field. Stabilization is also reliable, enabling me to take photos handheld at lower shutter speeds, with the limit being about 1/250s at 400mm.
This lens delivers good sharpness for the price, particularly in the 100-300mm range. However, you’ll notice a significant loss of detail at 400mm, but the image is still beautiful unless you’re pixel-peeping. This Sigma model is superior to the RF 100-400mm Canon lens in terms of build quality and stabilization, but it’s also bulkier.
“Keep your eyes on the variable aperture. In low light, you’ll have to bump up the ISO or increase the shutter speed, which is something beginners forget to do until they notice how blurry their photos are.”
To ensure every 100-400mm lens I recommend in this article is actually reliable in real-world scenarios, I performed in-depth hands-on testing together with my FixThePhoto teammates. Even though I did most of the testing when out in the field, my coworkers helped by taking photos in the genres they’re proficient in – wildlife, sports, portraiture, and travel.
For multiple weeks, we’ve been trying out over a dozen telephoto zooms, taking photos of everything from birds in flight to golden hour street performances. Several lenses offered solid performance, but failed to earn a place on our list. For instance:
We tested each 100 400 lens using these criteria:
The entire testing phase took about a month, which consisted of real-world shoots and thousands of comparison photos. After putting in so much work, we put together this list of 100-400mm lenses that aren’t just technically sound, but are good enough to become your most trusted ally in the field.
Having tried out dozens of lenses, I’ve concluded that there’s no single “best” lens that I can recommend. The choice depends on your needs and budget. All featured models can outperform others in specific scenarios, so picking the correct 100 to 400mm lens hinges a lot on properly determining your priorities. If you need help making your choice, keep this in mind:
