Canon Digital Wide Angle Lens: Canon vs Tamron vs Sigma
For this comparison with the Canon digital wide angle lens, the following lenses will be considered: Canon 24-70mm F/2.8 Wide Telephoto, Sigma 24-70mm F/2.8 Macro and Tamron Zoom Wide Angle-Telephoto AF 28-75mm f/2.8.
The Sigma lens is a great option for people who are just starting out. They will then move to the Canon when they gain the necessary insights. When compared to Canon, the Sigma is a slow responder to auto focus. It adds in more noise while focusing and has demonstrated problems while in communication with the infrared metering.
The upside is the price. It is also great for use as a video lens for the given price range. If you do not find the above-mentioned issues to be a problem, then the Sigma lens should be a great choice. If you are into hybrid shooting, then the Canon lens affords better image quality and performance.
The Tamron lenses are still cheaper when compared to Sigma and Canon. It is a good choice for a travel lens. However, when faced with adverse weather conditions, the Tamron starts to falter. The Canon is better than Sigma and Tamron at handling weather. Tamron lacks weather sealing, quick auto focus and a silent motor. Also, it is not great for shooting in fog, because moisture can creep in easily and ruin the lens. The Tamron is a good choice if you are only going to deal with video and have no concerns regarding the weather and auto focus.
