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.

Review – Canon EF 16-35mm f/2.8L II

Review – Canon EF 16-35mm f/2.8L II

New Review
Our review of the Canon EF 16-35mm f/2.8L II has been posted. Justin was eager to know whether or not it was worth the money over the very good EF 17-40 f/4L.

For the type of event work Justin does, it looks like he does think it’s better. Although I’d be less inclined to recommend it over its cheaper cousin if you’re primarily shooting landscape. The corner softness on the EF 16-35mm f/2.8L II isn’t any better than the EF 17-40 f/4L, the filter size difference could also be an issue for some people. However, if you need that stop of light, the EF 16-35 f/2.8L II is really your only choice in the Canon lineup.

Says Justin
“The 16-35mm f/2.8 L II beats my 17-40 f/4L in all aspects hands-down, except for cost. While I won’t find myself making the upgrade anytime soon, I did find the superior optics and faster aperture a boon in many situations I was in while working with the 16-35. The weight difference became less significant, and I actually mistook one lens for the other while packing my kit one day.”

Canon EF 12-24 f/2.8L [CR1]

Canon EF 12-24 f/2.8L [CR1]

Going wider?
We’ve spoken about the existence of an EF 14-24 f/2.8L in the past, a lens that a lot of people want to see come to fruition.

We’ve been told that an EF 12-24 f/2.8L exists in prototype form and could become a product instead of the EF 14-24 f/2.8L. I can only recall Sigma making such a lens for full frame cameras. Going this wide would certainly put some space between the cheaper (assuming based on Canon pricing history) EF 17-40 f/4L and EF 16-35 f/2.8L II.

This is the first I have heard of an EF 12-24 f/2.8L, so take it with a big grain of salt. This could be a better range in an f/4 variant, as it would be great for both full frame and APS-C and would really reduce size and weight compared to a 2.8 version.
