Full-Frame Canon EF 17-40mm F/4L

[StevenAunan]

I've had the 17-40mm for about a week now, but haven't spent a ton of time with it. Here are a few photos and some initial impressions.

With the RF adapter, the lens is just as long as the RF 24-105 L, but is slightly lighter and not as bulky. Both lenses share the same filter size (77mm) so the newer EW-83N hood also fits the older lens. The focus ring is a bit stiff (which could be due to its age), but I don't do much manual focus shooting anyway. The zoom ring feels slick and plasticky, but the lens made its debut in 2003 and it is made of plastic. I dig the old-school Canon look. I'm really happy with the focal length (which is why I bought it) and the image quality looks just fine. Would I prefer an F/2.8? Yes. Would I prefer an RF lens? Yes. But I would heartily recommend this lens for anyone on a budget who still wants L quality glass.

I like Ken Rockwell's reviews, so here's the link: https://www.kenrockwell.com/canon/lenses/17-40mm.htm

I agree with your recommendation. I have really enjoyed mine for the time I have had it.

Only EF lens i have left, swapped to RF for all others. No intention of getting rid of it any time soon, a great lens.

I can never get my R5 Mk 1 to shoot at 55924/44739201 sec, it always wants to round it to 1/800th sec. Must be of of those advanced features of the Mk II.

I heard that Canon produced a secret variant of the R5 Mk II that has such a highly precise shutter as Steven's camera. Someone said that it might be known internally at Canon as the R5 Mk 105196/52598.

This is the second time this website has misreported the shutter speed. I looked at the raw EXIF data on my MacBook, and it is reported correctly. But I'm going with Bryan's conclusion that I own an R5 Mk 105196/52598,

If you view the metadata from the individual file it shows 1/800 sec..
