Dustin Abbott posted his exhaustive Sigma 18-50mm F2.8 DN review. From his conclusion:

[…] Autofocus was fantastic, image quality looks great, and the lens remains very impressive despite its small size.

This is a great little general purpose/travel lens, as it affords enough flexibility in the focal length to shoot many scenes, and the constant maximum aperture of F2.8 gives you more flexibility in different lighting situations.

It’s great to see Canon’s RF mount starting to open to these third party offerings, and very quickly we will see the amount of lenses available for RF-S (APS-C) tripled due to Canon’s move to open the protocols. This lens isn’t cheap, per se, at $599 USD, but I’d rather spend a few hundred extra bucks to buy this lens over the current Canon options any day of the week.

Pros:

  • Fantastic job porting to Canon
  • Extremely compact and lightweight
  • Nicely made with a weather sealing gasket
  • Useful focal range with constant F2.8 aperture
  • Great autofocus performance
  • Good video AF performance
  • Minimal focus breathing
  • Good sharpness across zoom range
  • Nice bokeh in most situations
  • Fairly good coma performance
  • Nice build and handling than RF lenses

Cons:

  • No optical stabilizer
  • Fairly strong barrel distortion at 18mm
  • Some ghosting in certain lighting conditions
  • Flare for RF lens mount slightly interferes with MF ring

I strongly recommend you have a look to Dustin Abbott’s review, beyond what is featured here. The review is comprehensive and delivers all the information you night want to know. Moreover, the review comes with sample images, test charts, and more. So, if you are on the fence for the this little Sigma jewel, have a look at the review.
