Lens quality in this video Karl talks you through lens quality and shows and talks to you about a variety of the lenses that he owns and uses. Comments April 18, 2018 Log in to Reply Jacques Hart Hey Karl, You as an experienced photographer, what’s your opinion on “off brand” lenses? For example if you have a canon camera, you would use canon lenses. Besides these canon lenses there are also brands such as sigma and tamron that could work on the canon body. Do you know how they fare against the canon lens? May 2, 2018 Log in to Reply Karl Taylor Sigma and Tamron both make good lenses. Lenses have come a long way in the last 10 years so it’s not always essential to have camera brand ones. Sony use Zeiss lenses. Comments You must be logged in to leave a comment.
