Compare Canon EF 17-40mm f 4L USM Lens vs Canon RF 15-30mm f 4.5-6.3 IS STM Lens vs Canon RF 14-35mm f 4 L IS USM Tips & Reviews. About Us. The Professional's
The EF 17–40mm f/4L USM lens is a wide-angle lens made by Canon Inc. The lens has an EF mount to work with the EOS line of cameras. Other than the front element, it is sealed against dust and water, and features a diaphragm which remains nearly circular from f /4 to f /8. It is one of the few Canon photo lenses that are parfocal.
As for the other lenses, I really wanted to like the Canon EF-S 17-55mm f/2.8 IS USM, but it seemed to take unusually few "keepers" in similar shooting situations to the EF24-105L. The captured colors were a little cooler, and the IS comparatively very loud (audible without putting your ear to the lens).
