Hey there, fellow photography enthusiasts! I’m excited to share my comprehensive comparison between two of the most talked-about 35mm lenses on the market today. If you’re anything like me, you’ve probably spent countless hours researching, watching YouTube videos, and reading forums trying to decide between the Tamron SP 35mm f/1.4 Di USD and the Sigma 35mm f/1.4 Art. Well, I’ve done all the heavy lifting for you, and I’m ready to share everything I’ve discovered!
Why This Comparison Matters In 2025?
Let me tell you a little story. Last month, I was shooting a wedding and found myself frustrated with my current 35mm lens. The images weren’t as sharp as I wanted, and the bokeh just wasn’t giving me that creamy, professional look I crave. That’s when I decided to dive deep into the world of third-party 35mm lenses, and let me tell you – what I discovered shocked me!
The 35mm focal length is, in my opinion, the perfect all-around lens. It’s wide enough for environmental portraits and street photography, yet tight enough for intimate portraits and general shooting. I’ve discovered that having a top-quality 35mm in my bag has transformed my photography, and I’m betting it will do the same for you.
Quick Specs Overview: Tamron SP 35mm F/1.4 Di USD vs Sigma
Before we dive deep, let’s get the basic specs out of the way:
Tamron SP 35mm f/1.4 Di USD:
- Focal Length: 35mm
- Maximum Aperture: f/1.4
- Mounts: Canon EF, Nikon F
- Weight: 805-815g
- Filter Size: 72mm
- Weather Sealing: Yes
- Price: Around $899
Sigma 35mm f/1.4 DG HSM Art:
- Focal Length: 35mm
- Maximum Aperture: f/1.4
- Mounts: Canon EF, Nikon F, Sony E, Pentax K, Sigma SA
- Weight: 665g
- Filter Size: 67mm
- Weather Sealing: No
- Price: Around $799
Right off the bat, I notice some interesting differences. The Tamron is heavier but offers weather sealing, while the Sigma is lighter and more compact. But specs don’t tell the whole story – let’s get into the real performance!
Sharpness Showdown: Tamron SP 35mm F/1.4 Di USD vs Sigma
I’ll be honest with you – when I first started testing these lenses, I expected Sigma to dominate in sharpness. After all, the Art series has built quite a reputation for optical excellence. But what I discovered through extensive testing (and backed by technical data from LensTip) really surprised me.
Center Sharpness at f/1.4
Here’s where things get interesting. According to my tests and confirmed by LensTip’s technical analysis, the Tamron SP 35mm f/1.4 is actually distinctly sharper than the Sigma 35mm Art when shooting wide open at f/1.4.
I discovered this during a recent portrait session. I was shooting both lenses back-to-back, and when I got back to my editing station, I couldn’t believe my eyes. The Tamron images had this incredible bite and clarity that the Sigma just couldn’t match at f/1.4. The center sharpness was so impressive that I found myself zooming in to 100% just to make sure I wasn’t imagining things!
The technical data backs this up perfectly. LensTip’s MTF tests show that the Tamron exceeds 44 lpmm at f/1.4, which they describe as a “sensational value.” In fact, they found that the Tamron’s center sharpness at f/1.4 is roughly equal to or even better than the Sigma at f/2.8. That’s not just a small difference – that’s a full stop of performance advantage!
Edge-to-Edge Performance
But center sharpness isn’t everything, right? We need to know how these lenses perform across the entire frame. Once again, the Tamron impressed me.
During a landscape photography trip last week, I tested both lenses for corner-to-corner sharpness. The Tamron maintained excellent sharpness across the frame, while the Sigma showed some softness in the corners, especially when shooting wide open. LensTip’s tests confirm this – they found that the Tamron “outdistances the Sigma A 35mm f/1.4 DG HSM with ease” when it comes to edge performance.
What does this mean for you in real-world shooting? If you’re a landscape photographer or someone who values edge-to-edge sharpness, the Tamron has a clear advantage. I’ve found this particularly useful when shooting architecture or cityscapes where corner sharpness really matters.
Stopped-Down Performance
Now, what happens when we stop these lenses down? I tested both at f/2.8, f/4, and f/8, and here’s what I found:
At f/2.8, both lenses perform exceptionally well, but the Tamron still maintains a slight edge in the center. By f/4, the differences become much less noticeable, and by f/8, both lenses are producing incredibly sharp images across the frame.
The interesting thing is that the Tamron reaches its peak performance at f/2.8 to f/4, with results close to 49 lpmm – which is about as good as it gets for 35mm lenses. The Sigma catches up but never quite matches the Tamron’s peak performance.
Optical Performance: Beyond Sharpness
Sharpness is great, but there’s so much more to lens performance. Let’s talk about the other optical characteristics that really matter in real-world shooting.
Chromatic Aberration: The Color Fringing Battle
If you’ve ever shot high-contrast scenes, you know how annoying chromatic aberration can be. Those purple and green fringes around high-contrast edges can ruin an otherwise perfect shot.
In my testing, I found that the Sigma 35mm Art has better chromatic aberration control than the Tamron. LensTip’s technical tests confirm this – they found that Sigma and Canon lenses keep chromatic aberration close to 0.03-0.04%, while the Tamron shows higher levels.
However, I want to put this in perspective. Even though the Tamron has more chromatic aberration than the Sigma, it’s still described as “low or very low” in absolute terms. In my real-world shooting, I only notice the difference when pixel-peeping at 100% or when shooting extremely high-contrast scenes.
For most practical purposes, both lenses handle chromatic aberration very well, and any issues can easily be corrected in post-processing. But if you’re the type of photographer who wants the absolute best optical performance straight out of camera, the Sigma has the edge here.
Distortion: Keeping Lines Straight
Distortion is one of those things you might not notice until it’s too late. Nothing ruins an architectural shot like curved lines that should be straight!
In my testing, I found that the Sigma 35mm Art has better distortion control than the Tamron. LensTip’s measurements show:
- Sigma: -0.59% on APS-C, -1.09% on full frame
- Tamron: -0.47% on APS-C, -1.20% on full frame
Again, I want to emphasize that both lenses perform very well in this category. The differences are subtle and only really noticeable when shooting architectural subjects with lots of straight lines. For most photography genres, including portraits, street photography, and general shooting, you probably won’t notice the difference.
Coma and Astrophotography Performance
If you’re into astrophotography or night photography, coma performance is crucial. Coma is that optical aberration that makes stars look like little comets instead of sharp points of light.
From my testing and the technical data I’ve reviewed, the Sigma 35mm Art has better coma control than the Tamron. LensTip found that the Sigma has astigmatism of just 4%, compared to the Tamron’s 7.6%.
What does this mean for you? If you’re a serious astrophotographer, the Sigma might be the better choice. I tested both lenses during a recent night photography session, and while both performed well, the Sigma produced slightly better star shapes in the corners of the frame.
However, if astrophotography isn’t your main thing, this difference probably won’t matter much to you. For general night photography and cityscapes, both lenses perform admirably.
Vignetting and Light Falloff
Vignetting is that darkening of the image corners that happens with most lenses, especially when shooting wide open. Some photographers love it for its artistic effect, while others prefer to minimize it.
In my testing, I found that both lenses show significant vignetting at f/1.4, which is pretty normal for fast 35mm primes. The Tamron might have slightly more vignetting, but the difference is minimal.
The good news is that vignetting improves dramatically for both lenses by f/2.8, and by f/4, it’s barely noticeable. Plus, most modern cameras and post-processing software have excellent vignetting correction tools, so this isn’t a major concern for most photographers.
Build Quality and Handling: Tamron SP 35mm F/1.4 Di USD vs Sigma
Specs and technical performance are great, but how do these lenses actually feel in your hands? After weeks of shooting with both lenses, I’ve got some strong opinions on this.
Tamron SP 35mm f/1.4: The Premium Feel
The first thing I noticed when I picked up the Tamron was its substantial feel. At 805-815g, it’s definitely not a lightweight lens, but that weight translates to a feeling of quality and durability.
The build quality is exceptional – the lens feels solid and well-constructed. I love the rubberized focusing ring, which turns smoothly about 150° and allows for precise manual focusing. The weather sealing is a nice touch, giving me confidence when shooting in challenging conditions.
One feature I really appreciate is the focus distance window on top of the lens. It’s not just for show – I actually find it useful when shooting in low light or when I need to quickly check my focus distance.
The AF/MF switch is well-placed and easy to operate, even when I’m not looking at it. And the lens hood has a spring-loaded lock, which is a small but appreciated detail that prevents the hood from accidentally falling off.
Sigma 35mm f/1.4 Art: The Compact Contender
The Sigma 35mm Art feels noticeably lighter and more compact than the Tamron. At 665g, it’s about 150g lighter, which might not sound like much, but you definitely notice it during a long shooting session.
The build quality is still very good, with a metal barrel and quality construction. The focusing ring is smooth but has a shorter throw at about 90°, which some photographers might prefer for quicker adjustments, but others might find less precise for manual focusing.
Like the Tamron, the Sigma has a focus distance window and an AF/MF switch. However, it lacks weather sealing, which might be a concern if you frequently shoot in rain or dusty conditions.
Real-World Handling
After shooting with both lenses extensively, I’ve developed some clear preferences:
For studio work and controlled environments, I prefer the Tamron. The extra weight actually helps stabilize the camera, and the precise focusing ring is great for manual focus work.
For street photography and travel, the Sigma’s lighter weight and smaller size make it more appealing. I can carry it all day without fatigue, and it’s less conspicuous when shooting in public.
For wedding and event photography, it’s a toss-up. I love the Tamron’s weather sealing for outdoor ceremonies, but the Sigma’s lighter weight is nice during long receptions.
Autofocus Performance: Speed and Accuracy
In today’s fast-paced photography world, autofocus performance can make or break a shot. I’ve tested both lenses extensively in various shooting conditions to see how they perform.
Tamron’s USD (Ultrasonic Silent Drive)
The Tamron uses their USD autofocus system, which is a ring-type ultrasonic motor. In my testing, I found it to be fast, accurate, and virtually silent.
During a recent sports photography session, the Tamron kept up with fast-moving subjects admirably. The autofocus was decisive and locked onto subjects quickly, even in challenging lighting conditions.
One thing I really appreciate is the full-time manual focus override. Even when the lens is in AF mode, I can grab the focusing ring and make fine adjustments without having to switch to MF mode. This is incredibly useful for portrait work where I might want to fine-tune focus on the eyes.
Sigma’s HSM (Hyper Sonic Motor)
The Sigma uses their HSM system, which is also a ring-type ultrasonic motor. In my testing, it performed very similarly to the Tamron – fast, accurate, and quiet.
I used the Sigma for a recent event photography job, and it handled the changing focus distances with ease. The autofocus was responsive and didn’t hunt unnecessarily, even in low light conditions.
Like the Tamron, the Sigma offers full-time manual focus override, which is great for those moments when you need to take control.
Real-World Autofocus Performance
After extensive testing, I can say that both lenses have excellent autofocus systems that will serve most photographers well. However, there are some subtle differences:
The Tamron’s autofocus feels slightly more decisive and confident, especially in low light. During a recent night photography session, it locked onto subjects more quickly than the Sigma.
The Sigma’s autofocus might be slightly faster in bright daylight conditions, but the difference is minimal.
Both lenses work well with camera autofocus systems, but I found that the Tamron seemed to work slightly better with my Canon DSLR’s autofocus system, producing more consistent results.
Bokeh Quality: The Creamy Dream
Let’s talk about what really matters for many photographers – bokeh quality. That beautiful, creamy background blur can make or break a portrait, and both of these lenses are known for their excellent bokeh characteristics.
Tamron’s Bokeh: Smooth and Controlled
In my portrait sessions, the Tamron produces beautiful, smooth bokeh that I absolutely love. The out-of-focus areas have a nice, even rendering without any harsh edges or distracting patterns.
I recently shot a portrait session with the Tamron at f/1.4, and the background separation was stunning. The subject just popped off the background, and the bokeh had this creamy quality that looked professional and expensive.
One thing I noticed is that the Tamron’s bokeh remains smooth and pleasing even when shooting subjects with complex backgrounds. The lens handles busy backgrounds well, maintaining that creamy quality without getting nervous or choppy.
Sigma’s Bokeh: The Classic Cream
The Sigma 35mm Art has built quite a reputation for its beautiful bokeh, and after testing it extensively, I can confirm that reputation is well-deserved.
In my testing, the Sigma produces what many photographers describe as “creamier” bokeh than the Tamron. There’s a certain quality to it that’s hard to describe but easy to see – it’s just incredibly smooth and pleasing to the eye.
During a recent wedding shoot, I used the Sigma for some intimate portraits, and the results were stunning. The background melted away into this beautiful, creamy blur that made the subjects stand out perfectly.
Technical Bokeh Analysis
From a technical standpoint, both lenses perform very well in the bokeh department, but there are some differences:
The Tamron shows very slight onion-ring bokeh when pixel-peeping, which is connected to its aspherical elements. However, this effect is so minimal that it’s really not noticeable in normal viewing.
The Sigma’s bokeh is generally considered to have a slight edge in smoothness, which might be due to its optical design.
Both lenses show some mechanical vignetting at f/1.4, but this improves significantly by f/2.0 and is mostly gone by f/2.8.
Color Rendition and Contrast
Color reproduction is one of those subtle but important aspects of lens performance that can really affect the final look of your images.
Tamron’s Color Performance
In my testing, I found that the Tamron produces vibrant, punchy colors without any obvious color cast. The images have a modern, clean look that I really appreciate.
During a recent landscape photography session, the Tamron captured colors beautifully – blues were deep and rich, greens were natural and vibrant, and skin tones looked accurate and pleasing.
One thing I really like about the Tamron’s color rendering is that it’s very neutral and accurate. This gives me a great starting point for post-processing, whether I want to enhance the colors or keep them natural.
Sigma’s Color Performance
The Sigma 35mm Art also produces excellent colors, but with a slightly different character than the Tamron. In my testing, I found that the Sigma’s colors are slightly warmer and more saturated straight out of camera.
During a portrait session, the Sigma rendered skin tones beautifully, with a natural warmth that looked flattering without being overly saturated.
Like the Tamron, the Sigma’s color rendering is accurate and doesn’t show any obvious color casts. The differences are subtle but noticeable when comparing images side by side.
