Worlds FIRST SIGMA LENS for Canon RF  Sigma 18-50mm f28

Introduction

Hey there, fellow photography enthusiasts! Today, I want to share with you my first impressions of the world’s first Canon RF lens made by Sigma, the 18-50 f2.8 DC DN lens. I recently had the opportunity to test out this lens, thanks to Sigma Canada, and I’m excited to give you all the details and my thoughts on whether this lens is worth considering for your photography kit.

First Impressions

I’ve only had this lens for a few days, during which I’ve taken a few hundred photos. From capturing a rainbow to a happy boat captain and a girl in a cowboy hat, I’ll be sharing my initial thoughts on the image quality and performance of this lens.

Key Features

The Sigma 18-50 is an APS-C lens, compatible with Canon full-frame cameras like the R5 and R6. It automatically switches your camera to APS-C mode to avoid vignetting, making it suitable for both photography and videography. The constant f2.8 aperture throughout the zoom range allows for better low-light performance and creative depth of field effects.

Comparison with Canon Lenses

Compared to Canon’s APS-C offerings, like the 18-45 variable aperture lens, the Sigma 18-50 stands out with its constant f2.8 aperture, making it a more versatile and capable option for APS-C shooters. The compact size of the Sigma lens, along with its dust and splash resistance and included lens hood, adds to its appeal.

Performance and Limitations

Attaching a third-party lens like the Sigma 18-50 to a Canon body poses no limitations in terms of functionality, as observed during testing on a Canon R6. The lens performs well in terms of autofocus, image quality, and minimum focusing distance, making it a versatile tool for various shooting scenarios.

Considerations and Conclusion

While the Sigma 18-50 lacks image stabilization and is designed for APS-C sensors, it offers significant advantages in terms of optical performance and value compared to Canon’s APS-C lens lineup. For APS-C shooters looking for a high-quality zoom lens with a constant aperture, the Sigma 18-50 f2.8 DC DN is a compelling option to consider.

Now, let’s delve into some questions you might have about the Sigma 18-50 lens:

1. **Can full-frame shooters use the Sigma 18-50 lens on their cameras?**
– Yes, full-frame shooters can use the Sigma 18-50 lens on their Canon R5 or R6 cameras. The lens automatically switches the camera to APS-C mode to avoid vignetting.

2. **Does the lack of image stabilization in the Sigma 18-50 lens affect its performance?**
– While the lens does not have built-in image stabilization, it is less critical now with cameras like the Canon R6 that feature in-body image stabilization. The smaller size of the lens is also a benefit of omitting image stabilization.

3. **How does the Sigma 18-50 lens compare to Canon’s APS-C offerings in terms of aperture and performance?**
– The Sigma 18-50 lens stands out with its constant f2.8 aperture, offering better low-light performance compared to Canon’s variable aperture lenses. It also provides excellent image quality and versatility for APS-C shooters.

4. **Is the Sigma 18-50 lens a good investment for APS-C shooters considering upgrading to full-frame cameras in the future?**
– If you plan to stick with APS-C format for the foreseeable future and value a lens with a constant aperture and high optical performance, the Sigma 18-50 lens is a worthwhile investment.

5. **Are there any compatibility issues or limitations when using the Sigma 18-50 lens on a Canon body?**
– During testing, no compatibility issues or limitations were found when using the Sigma 18-50 lens on a Canon R6. The lens integrates seamlessly with Canon’s menu settings, offering a user experience similar to native RF lenses.

I hope these insights and answers help you make an informed decision about the Sigma 18-50 lens for your photography needs. Remember to always put your camera to good use and keep capturing those amazing moments!
