EOS Bodies / Patent: Canon 11-24mm f/4 Lens
« on: January 25, 2014, 08:46:42 AM »

Egami has shown that Canon has filed a patent for an ultra-wide angle zoom:


(Translated)


Description and self-interpretation of the patent literature


Patent Publication No. 2014-10286


  • Publication date 2014.1.20

  • Filing date 2012.6.29



  • Example 1


  • Zoom ratio 2.06

  • Focal length f = 11.30-18.00-23.30mm

  • Fno. 4.10

  • Half angle ω = 62.42-50.24-42.88mm

  • Image height Y = 21.64mm

  • 172.19-161.28-162.86mm overall length of the lens

  • BF 38.82-52.31-63.15mm



  • Canon users have been left out in this focal range for quite some time. With Nikon and their legendary 14-24mm f/2.8G ED and  other third party offerings filling up the gap in the market. Can Canon produce an optically superior lens that also has such a shallow depth of field? Until they do, the only wide-angle zooms that Canon makes that come close are the 16-35 f/2.8 L II or the 8-15mm f/4L Fisheye.

    Thanks for posting the review even though it is an old lens :-)

    I am actually about to pull the trigger on either this lens, or its 100mm brother for a portrait lens attached to a 6D. These portraits will mostly be my kids and family. Any thoughts on the 100mm as a portrait lens vs. the 85mm? I am leaning towards the 100mm because I shoot my daughter at basket ball also and my 70-200 f/4 just isn't letting in enough light at the gym.

    BTW, I too, don't mean to be rude :-)

    Which 100mm are you asking about? If you're talking about the Macro L it's one of my favourite portrait lenses: http://www.canonrumors.com/reviews/review-canon-ef-100-f2-8l-is-macro/. I worry that the AF on it may not be able to keep up in sporting situations. The IS will certainly help, but it's by no means a "sports" lens (switching the focus limiter away from the macro setting would help too).

    I had the 100mm f/2.8 Macro (non L) and it was nice, but if I remember correctly focus was even slower and a lack of IS really hindered hand-held shots around 1/100th, especially on macro shots.

    The 85 had an incredible sale on recently, though even the price now is well placed by comparison. I'd skip the 100 Macro unless you're saving up for the L, and go for the 85 1.8 instead in this case.

    Kevl you know what? That was rude of me. I'm sorry. Let's get back to how the lens works shall we? You're clearly a fan of the 85 1.8, show us some of it's strengths and any possible weaknesses you've encountered after owning it for so long. Admittedly I've only had it off and on over the years, so never had a chance to put it through every available usage scenario.

    clartephoto, more great shots, thanks for sharing.  It's nice to have you on CR.

    The guy in the review can say that his images with the 1.2 are more magical... OK.. thanks. I wonder how one would quantify that. Could it be that when one drops $2,200 on a lens that they feel obligated to feel it is full of magic?
    Have you used the 1.2?  If not, how can you say he's right or wrong?

    No I have not used the 1.2. He is the one reviewing, how can he prove himself correct? What does "magical" mean? It is a meaningless statement and therefore completely unhelpful as a "review." It would make a lovely Tweet though...

    Quote
    The 1.2 lets in more light for sure, I'm not convinced it is sharper, and if focuses slower.

    I don't mean to be rude but this is one of the least helpful reviews I've ever seen on a reputable camera website.
    LOL back at you - the old "I don't mean to be rude" preceding the rude statement.  Saying that doesn't make it any less rude.

    I'm sorry you were offended, perhaps it was rude of someone to call this article a review...

    Good thing you can find over 100,000 meaningless statements over on my twitter feed! https://twitter.com/justinvl

    And I'm not going to debate about what is and isn't rude, that'll probably lead to how you were raised and it's best not to go there.

    Also, 85's are the perfect focal length for a bit of free-lensing!

    I was hoping your "LOL's" were because those cons were mostly jokes (sarcasm) but I see it was lost on you. No problem, you're right in your observations and I certainly *don't* think the 85 1.2 is worth the extra money (I haven't bought one) but I do compare the two because focal length is an obvious comparison tool. I did mention I compare it more in line with the 50 1.4, 40 2.8 and other "like-class" lenses.



    I don't know what your copy of the 50 1.4 is but my 85 1.8 makes my 50 look like it is constantly out of focus. They have similar chromatic issues though.

    My 50 performs great f/2.0 and onwards, where the 85 definitely was sharper opened up at 1.8. I also use a lens hood with my 50 but didn't have one for the 85 which would make a difference in some situations. The 50 is such a well used lens from so many you'll definitely find mixed feelings towards it in the forums on my "review" of it (or article, don't know how you feel about it so I'm treading lightly with my phrasing) http://www.canonrumors.com/reviews/review-canon-ef-50mm-f1-4/

    I'm also sorry you don't have enough magic in your life to be unable to understand it as a quantifiable statement, while I agree it's not a technical achievement that can be measured it seemed an apt description of the "feeling" I got out of the images produced between the two lenses, like love, but I wouldn't want to compare the feeling I get for my wife to that of a lens. Hopefully some day you'll feel the same about something  :'(

    Personally, I like the background to be smoothly blurred, but not wiped out entirely.  I'll offer some examples for your entertainment:

    Looking good and yeah, nice and sharp. It's definitely a great lens (especially for the price).

    The 85 f/1.8 is a very solid lens but the 85 f/1.2 is a distinct step up

    Many of you guys above are quite adamant you can't see a difference in shots from the 85 f/1.2 vs the 85 f/1.8 for the samples provided so far  - below are some shots I have taken on the f/1.2 which in my opinion just can't be replicated using the 85 f/1.8 (but I accept I may be wrong, so very happy to be proven incorrect):

    "Step Up" vs. step... different? I think people need to evaluate what they need. If it's fast or good AF then the 1.2 isn't a step up at all. But I do agree with you, as I wrote, there's something in the files right out of camera with the 1.2 that I couldn't compare to the 1.8 (trust me, I tried).

    Great shots.

    I have to LOL at this review.

    I just purchased this lens for $319 at B&H. I shoot with a 5D3, 70-200 2.8L, 24-105L, and a 50 1.4. My verdict on this lens? It is brilliant.

    I don't expect it to match a lens that costs nearly SEVEN TIMES AS MUCH. The fact that there is so much debate on this subject tells me I'm not just drinking the koolaid the lens it truly brilliant.

    The guy in the review can say that his images with the 1.2 are more magical... OK.. thanks. I wonder how one would quantify that. Could it be that when one drops $2,200 on a lens that they feel obligated to feel it is full of magic?

    The 1.2 lets in more light for sure, I'm not convinced it is sharper, and if focuses slower.

    As the reviewer put it the only cons to the 1.8 are no hood included and it doesn't have a red ring on it. I've got two red rings, one is brilliant the other is OK (guess which? lol). I'm not sure I have thought about the ring on either of them in more than a passing way ever.

    I don't mean to be rude but this is one of the least helpful reviews I've ever seen on a reputable camera website.

    I was hoping your "LOL's" were because those cons were mostly jokes (sarcasm) but I see it was lost on you.

    And hey, thanks for not meaning to be rude.

    Nice to see a review of my favorite lens by my favorite reviewer!

    I'd have to say his observations match mine regarding performance at various apertures, fast autofocus, light weight, etc...

    The funny thing about this lens is how people always compare this great all around portrait lens to it's very specialized 1.2 L cousin.  Rather than a technical comparison, we end up discussing feelings, intagibles, magic and other vague things.

    I have no doubt that under some conditions, the L version will give more contrast and more saturated colors.  (I have the 135 L and that is certainly a good example of the L effect.)

    The thing is... in Lightroom, I have sliders for saturation, clarity and sharpness that will give me any look I want.  I can make images from the light, cheap 85 look just like the ones from the heavy, expensive 85, for all practical purposes.

    So in my mind, the only advantage of the L lens is the 1.2 aperture.  Would I use that if I had it?  Considering that I normally use my 85 around F/2.5, I'd say not.

    What we are really seeing here, in my opinion, is a victory for the Canon marketing department.  Many photographers buy the 85 L as a prestige symbol and very few of them really use it to any advantage that could not be more easily and cheaply accomplished with the 85 F/1.8.   Or the 135 L, if your goal is to wipe out the background and create dreamy bokeh.

    I think this review is a good example of how most people think about these two lenses.  They can tell the 1.8 is a nice, useful, practical lens, but they are just sure that the extreme price of the 1.2 L and the magic red ring must symbolize something very important.

    Your mileage will certainly vary!  :)

    Yeah, I kept going back to my (in focus) images from the 1.2 being like "ooooh that's really nice" and while I had some good photos with the 1.8 they just weren't as much of a hit. Same difference between the 50 1.2 & 1.4 in my opinion.  There IS something there, maybe even un-quantifiable, but it will almost certainly cost you that much more for a marginal quantifiable difference... and not necessarily "improvement," but aesthetic difference which is really what this is all about right?

    I really think Canon should have improved the 24-105 f4 L and left this one on the shelf. The only appeal of the range is if you have a 2.8. At this price I would rather invest in the Tamron 24-70 f2.8.

    Yeah, and with the Sigma 24-105 out now receiving excellent reviews I see the place for this lens a little less. *except* for how compact it is.

    I have a dozen stands, none of them are the same. If a C-stand is out of your price range and/or too heavy, the 420 combi boom is excellent. There's also a steel base version that I'd recommend if you can handle a bit more weight since it *might* negate the need of a sandbag in some scenarios (though I still recommend one).

    If you're going to put three flashes on there you may also want to consider a counter-weight. Either a small sandbag, or one of these small weights: http://www.bhphotovideo.com/c/product/5194-REG/Manfrotto_172_172_Counter_Balance_Weight.html helps to off-set the balance of the heavy flashes with all their batteries.

    The Canon 24-70 f4 L IS seems to be treated like the red headed stepchild on the internet. It's not easy to be the little brother to the Canon 24-70 F2.8 II lens. I first borrowed 24-70 F4 lens for a 2 week trip to Glacier National Park. The lens was superb on my 5D3.  Easy to hike with and IS. I liked it so much that I bought one when I got home. On the 2 copies that I have used of this lens, both have been very sharp, fast accurate AF and great IS.
     I have used the  Canon 24-70 F2.8 II and IMO the 24-70 F4 gives up little in IQ to his bigger brother.
    I have found in my use of this lens that the 50mm focal point is quite contrary to popular opinion on the interenet, the 2 copies of this lens that I have used were/are very sharp.
    This Canon 24-70 F4 L IS plus my Canon 70-200 F2.8 II make for a superb combination. Same filter size. Both have Canon's newest IS. Superb image quality and sharpness.
    If you don't really need the f2.8 aperature and want IS, this is a lens you really should try.
    The much loved Canon 24-105 of course is another option to consider, especially given the price of it now. I chose the Canon 24-70 F4 over the 24-105 for it's much better handling of distortion at 24mm and upgraded IS.
    I dont miss the extra reach of the 24-105 because I carry the 70-200 for that. That's my real world review of this lens.

    Perfect. Thanks!
