The first thing you’ll notice about the Sigma 35mm f/1.4 Art is its substantial presence. This is a lens that means business, with a solid metal construction that feels premium in every way. Weighing in at 665g, it’s no lightweight, but the build quality assures you this lens can withstand professional use.
I’ve shot with this lens in everything from studio environments to dusty outdoor locations, and its weather sealing has never let me down. The dust and splash resistance give me confidence when shooting in challenging conditions—a must-have for working professionals.
The focus ring is smooth and well-damped, perfect for manual focusing when needed. I particularly appreciate the petal-shaped lens hood that comes included, which provides excellent protection against flare while being sturdy enough to withstand minor bumps.
Optical Performance
Where the Sigma 35mm f/1.4 Art truly shines is in its optical performance. The wide f/1.4 aperture isn’t just a marketing point—it delivers exceptional low-light capability and beautiful background separation that elevates your images.
During a recent portrait session, I shot the same subject with both lenses, switching back and forth to compare. The Sigma produced noticeably creamier bokeh and better subject separation at the same distance, creating that three-dimensional quality that makes portraits truly pop.
Sharpness is exceptional across the frame, even when shooting wide open. I’ve printed large format images from files shot at f/1.4, and the detail is breathtaking. While many lenses need to be stopped down to achieve optimal sharpness, the Sigma delivers stunning results from f/1.4 onward.
Color rendering is another strong suit, with the Sigma producing rich, vibrant colors that require minimal post-processing. The contrast is excellent without being harsh, creating images with a pleasing three-dimensional quality.
Autofocus Performance
The Sigma’s HSM (hypersonic motor) autofocus is fast and accurate in most situations. During my testing, it locked onto subjects quickly and decisively, even in challenging lighting conditions. That said, it’s not the quietest autofocus system, which might be a consideration for photographers shooting in quiet environments.
One area where the autofocus occasionally struggles is in extreme low-light situations, where it may hunt briefly before locking focus. This is a common challenge with fast aperture lenses, but worth noting if you frequently shoot in very dark environments.
Low Light Capabilities
This is where the Sigma truly separates itself from the competition. The extra light-gathering ability of f/1.4 makes a significant difference in low-light situations. I’ve shot indoor events where the Sigma allowed me to capture clean images at lower ISOs than would have been possible with the f/1.8.
During a recent evening cityscape session, I was able to handhold shots at slower shutter speeds while maintaining lower ISO values, resulting in cleaner images with less noise. The combination of wide aperture and excellent sharpness makes the Sigma a powerhouse for available light photography.

The focus ring is smooth but smaller than the Sigma’s, which can make manual focusing slightly less precise. The lens hood is a simple cylindrical design rather than the petal-shaped hood included with the Sigma, but it still provides adequate protection against flare.
Optical Performance
While it can’t match the Sigma’s pure optical performance, the Tamron 35mm f/1.8 still delivers excellent image quality for its price point. Sharpness is very good across the frame, especially when stopped down to f/2.8 or f/4.
During my testing, I found the Tamron to be slightly softer than the Sigma when shooting wide open, particularly in the corners. However, for most practical applications, this difference is minimal and unlikely to be noticeable in normal-sized prints or web display.
Color rendering is neutral and accurate, though not as vibrant as the Sigma’s. The contrast is good but slightly lower than what the Sigma produces, resulting in images that may require a bit more post-processing to achieve the same level of “pop.”
Autofocus Performance
One area where the Tamron truly shines is its autofocus performance. The OSD (Optimized Silent Drive) motor is not only fast and accurate but also remarkably quiet. During my testing, the autofocus was virtually silent, making it ideal for shooting in quiet environments like ceremonies or wildlife photography.
The autofocus is also slightly faster than the Sigma’s in good lighting conditions, with less hunting and more decisive focus acquisition. This makes the Tamron an excellent choice for action photography and situations where capturing the moment is critical.
