Shootout: EF 16-35 f/4L IS vs EF 17-40 f/4L

Graham Clark has completed a shootout between the latest Canon ultra wide angle zoom, the EF 16-35 f/4L IS and the always dependable and very popular EF 17-40 f/4L.

There are tons of RAW files and video to whet your appetite if you happen to be undecided between the two lenses, or if you’re not sure you want to “upgrade” your EF 17-40 f/4L. I found this to be about the most thorough review and comparison between the two lenses, as well as showcasing the EF 16-35 f/4L IS.

Graham says in his conclusions
“The inclusion of Image Stabilization, incredible corner sharpness and bar-none the best CA performance on corners I’ve ever seen put the Canon 16-35 F4 IS at the top of a very short list of must-get Ultra-Wide Angle Zooms. If you’re a Canon or Sony landscape and/or a travel photographer in the market for a ultra-wide angle zoom, and/or you’re looking to upgrade whatever you currently have, this is the one to get.”

More Mentions of 2014 Being the Year of the Lens [CR1]

More Mentions of 2014 Being the Year of the Lens [CR1]

The year of the lens!
We’ve had a few confirmations that 2014 will be the “year of the lens” for Canon. While Nikon and Sony go into new markets such as full frame mirrorless and retro designs, Canon will apparently stay the course and concentrate on DSLRs and lenses for the EOS lineup.

What should we expect?

Firstly, a new worlds widest full frame zoom lens (nor sure what this could be), a wide angle zoom with IS (17-50 f/4L IS?), a new fast wide angle successor with “new technology” (35 f/1.4?). We can also expect two new tilt-shift lenses, a telephoto zoom successor (100-400?) as well as “budget high quality lenses”.

I’m starting to believe the hype, as the info is coming from known and new sources, and they all seem to be saying the same thing.

More to come.

Review – Canon EF 17-40mm f/4L

Review – Canon EF 17-40mm f/4L

New Review
Justin has completed his review of the Canon EF 17-40mm f/4L ultra wide angle zoom lens from Canon. For a lot of people, this is their first wide angle zoom and becomes a workhorse.

I know one landscape/nature photographer who uses this lens extensively and it’s used for about 75% of images that he sells, and he sells a lot! This is a great lens for publishing and using all the time. I have a hard time recommending the 16-35 f/2.8L II to anyone other than an event photographer. The EF 17-40mm f/4L is a workhorse that is reliable and doesn’t cost a whole heck of a lot.

Justin likes it a bit less than I do, but the review is pretty positive.

New Wide Angles Lenses in 2013 [CR2]

New Wide Angles Lenses in 2013 [CR2]

Announcements in the fall
We’re told that two new wide angle zooms for full frame will be coming from Canon in the next 6-8 months. At least one of them could be announced in Q4 of 2013.

One of the lenses will be the 14-24 f/2.8L, that will complete Canon’s run of lenses covering 14mm to 560mm.

The other will be a replacement to both the 16-35 f/2.8L II and the 17-40 f/4L. We’re told one of the configurations in test is an EF 16-50 f/4L IS.

This comes from a source that has been correct in the past, although timing is always hit and miss with Canon lenses.
