Drawbacks of Using Sigma 18-35 on Full Frame

When using the Sigma 18-35mm f/1.8 DC HSM Art lens on a full-frame camera, there are some drawbacks that you should be aware of:

  • Vignetting: You’ll experience vignetting, especially at wider focal lengths and wider apertures. This can be corrected in post-processing to an extent, but it’s something to be aware of.

  • Limited image circle: The lens is designed for APS-C sensors, so the full-frame sensor isn’t completely covered at wider focal lengths. This means you’ll have black corners in your images unless you crop, use DX mode, or accept the vignetting.

  • Autofocus quirks: Some full-frame cameras might have slight autofocus inconsistencies with this lens, particularly at the edges of the frame.

  • Alternative options: Consider other lenses such as the Sigma 14-24mm f/2.8 DG DN Art, Sony FE 16-35mm f/4 G OSS, or Tamron 17-28mm f/2.8 Di III RXD, which offer better compatibility and performance on full-frame cameras.

Before deciding to use the Sigma 18-35mm f/1.8 DC HSM Art lens on a full-frame camera, consider these drawbacks and evaluate whether they align with your shooting style and priorities.

Considerations When Using Sigma 18-35 on Full Frame

Consider the compatibility and performance of the Sigma 18-35mm lens on a full-frame camera before making a decision.

The Sigma 18-35mm lens is designed for APS-C sensors, so when used on a full-frame camera, there are several considerations to keep in mind. Vignetting is a common issue with this lens on full-frame, especially at wider focal lengths and wider apertures. Although it can be corrected in post-processing to some extent, it’s something to be aware of.

The lens also has a limited image circle, which means that the full-frame sensor isn’t completely covered at wider focal lengths, resulting in black corners in your images unless you crop, use DX mode, or accept the vignetting. Additionally, some full-frame cameras might experience autofocus quirks, particularly at the edges of the frame.

It’s important to consider how much vignetting bothers you, whether you prioritize compactness and speed over absolute image quality, and the compatibility of the lens with your specific camera model.

Alternative options, such as the Sigma 14-24mm f/2.8 DG DN Art, Sony FE 16-35mm f/4 G OSS, or Tamron 17-28mm f/2.8 Di III RXD, should also be considered before making a final decision.

Alternatives to Sigma 18-35 on Full Frame

For those seeking alternative options to the Sigma 18-35 lens on full frame, there are several compelling choices available. Consider the following alternatives:

  • Sigma 14-24mm f/2.8 DG DN Art: A full-frame ultra-wide zoom with excellent image quality and a bright aperture, but larger and heavier than the 18-35.

  • Sony FE 16-35mm f/4 G OSS: A compact and lightweight full-frame zoom with good image quality and image stabilization, but not as fast as the Sigma.

  • Tamron 17-28mm f/2.8 Di III RXD: Another APS-C lens with a similar focal length and aperture range as the Sigma, but with better full-frame compatibility due to its larger image circle.

  • Canon EF 16-35mm f/2.8L III USM: A professional-grade full-frame zoom lens with exceptional image quality and a fast aperture, but larger and heavier than the Sigma.

These alternatives offer a range of options for different shooting needs. Whether you prioritize image quality, compactness, or a specific focal length range, there’s a lens that can meet your requirements.

Be sure to consider factors such as size, weight, and compatibility with your camera when making your decision. Ultimately, the choice depends on your individual preferences and shooting style.
