Review on Ultra Wide Angle Zoom Lens for SLR Cameras - Canon EF 17-40mm f/4L USM by Mei Liana ᠌

Everything about him has already been said a hundred times. I will only note that the lens is old and not designed for modern matrices, so whoever has a new camera with dense pixels should first look at its resolution. I would say that for 2022 it is not ideal. I switched to the ultra-wide EF-S 10-18mm 4.5-5.6 IS STM: it costs a penny, it lies in a pocket in a sock, but its sharpness in the frame is at least as good, and night shooting is better due to the stub. The picture of 10-18 is worse, but there is less technical marriage, therefore, for a family home, I would recommend looking at new lenses. Moreover, Canon is clearly curtailing the OES line, it is already 30 years old, and finally, I think it has rolled out everything that it has worked out in cheap lenses.
