Nikon patents a camera hand grip strap and two zoom lenses with Diffractive Optical (DO) element inside

Nikon camera strap patent Nikon camera strap patent 2 Nikon camera strap patent 3

Nikon filed a paten 2013-134682t in Japan for a new 3-point camera hand grip strap. Similar products already exists from various manufacturers, including the Nikon AH-4.

Nikon 18-300mm DOE APS-C lens patent

New patents were also filed for a 18-300mm (APS-C) and 28-300mm (full frame) lenses, both with a Diffractive Optical (DO) element inside. Canon has a good article on their website describing the advantages of Diffractive Optical elements in lens design. The 18-300mm lens contains 16 elements in 13 groups and 3 aspherical elements. The 28-300mm lens has 19 elements in 14 groups and 3 aspherical elements.

    DO? Why not HRI?

  • Plug

    Given the earlier DO patent 300mm lens, these patents are a good sign that Nikon research is making progress in this area. Any chance that the 300 f4 later this year is DO and therefore very compact?

    • Yes, there was a 300mm f/4 DO lens patent: No indications when this lens will be announced.

    • tew

      DO is crap, that’s y canon’s 70-300 DO doesn’t sell right?

      • Plug

        Yes, to date DO has had its problems. The potential benefits are however worth the Nikon/Canon research departments persevering. Do you remember when autofocus was so poor that it was a hindrance or when digital was crap compared to film? They were technologies worth pursuing!

  • Nikon_wide

    Can I just get a reasonably priced Wide Angled Prime for APC? Say 12mm or 14mm.. I’d be happy with anything lower than 18mm in a prime. But would love a 12-14mm. Nikon1 users get a 10mm.

    • Shawn

      Nikon 1 10mm is 28mm FX equivalent, so they’re not really better off.

      • Neopulse

        27mm* 😛 (busting your chops)

    • Spy Black

      Samyang has one for you:

  • longzoom

    Canonities say their DO lenses are smaller, but optically no much difference to traditional design. Let us see.

    • MB

      Actually DO lenses are so far optically inferior, the only advantage is size and wight …

      • patto01

        Assuming you’re right, and I have no basis to question that, the DO designs would give people who like superzooms a smaller option. They already compromize quality for convenience, this would just take it a little further. Or, they might be for future mirrorless cameras!?

        • Neopulse

          My thoughts exactly. A beta testing I was thinking for possible future mirrorless applications.

        • Calibrator

          I was thinking about mirrorless cameras, too, as Nikon just brought the DX18-300 to the market.

          In fact the signs are getting clearer that the industry is preparing the next technology shift – from DSLRs to mirrorless “DSLR-like” bodies:

          – Canon did their first real step to get rid of the optical viewfinder: They developed a cropped sensor which does phase-detect AF on 80% (!) of the sensor area and will use it in their upcoming 70D. Given recent history they will equip all their cropped sensor bodies with it in the next years. It’s only a question of time now when they will replace the OVF with an EVF, drop the costly mirror mechanics, pentaprism/pentamirror, separate AF- and metering sensors.

          – Sony already has their fixed-mirror range but the rumor mill says that they will get rid of the fixed mirror early next year (announcements in late August, early September?). Lots of people were disappointed by the A99 because of image noise so Sony knows they need to get rid of the mirror quickly. In fact the A58 could be their last body with a mirror.
          This means that Sony also needs (and likely already has) PD-AF integrated in both cropped and full frame image sensors – and this in turn means that Nikon and Pentax could very likely buy & use them…

      • Plug

        Not necessarily. The earlier Canons were inconsistent in quality but that is many years ago. If I remember correctly contrast was often poor. But technology progresses rapidly and the assumption of inferior quality is not necessarily valid.

        • Dpablo unfiltered

          I’ve viewed photographs taken with the DO lenses. Let’s just say that I hope Nikon can do a better job. Of course, an 18-300 is probably a better choice for cost cutting optics than a $5000 prime lens.

          • longzoom

            Indeed. And I am not happy with all of kinds of non-optical VF’s. Not at all. But , you see, it’s just me.

  • Nitin Ulé

    Handgrips are already available for sale on many Chinese shopping sites.

    • gly

      Agreed, let the handgrip accessories go. Chances are they’ll be too expensive by comparison anyway.

      • Nitin Ulé

        I bought one for USD 3 only from Ali express .. Super built quality and total value for money.. I am sure original Nikon must be not lesser than $20. this one is worth every penny and very very useful especially city walk-around and in Jungle walk.

  • Photo-Jack

    Patents in the drawer are of no use for your customers. Nikon, get new lenses on the market; there is enough space left.

    • Calibrator

      Patents in the drawer are useful for the companies.

      Long gone are the times where a company only patents stuff it intends to bring to market.

  • D400

    Admin, I hope those Nikon D400 rumors are coming soon. It has been way too long without any rumors of any camera for far too long.

    • Nothing significant. There will be major announcements in August/September – not only Coolpix cameras. Some rumors point to two new DSLR cameras. Still, nothing confirmed.

    • Nilrem

      O come on, get a grip!

    • Spy Black

      Have you ever thought of perhaps getting a life?

    • Gord

      You know he doesn’t make the rumors right, he just reports them. Like he can’t just make articles that say “people are saying things about this product!”

      The way people talk about the D400, you’d think they were waiting for their cancer medication.

      • Calibrator

        > Like he can’t just make articles that say “people are saying things about this product!”

        Well, technically he could. Like certain companies…
        Wouldn’t have anything to do with journalism, though. 😉

        • Gord

          LOL TRUE SAY

          Luckily, Admin doesn’t go for that garbage and has a bit more meat behind what he publishes.

  • Smudger

    Just when we thought Nikon had lost the plot they come up with a strap that’s worthy of a patent.

    Good to see the design team have got their priorities right.

    • 103David

      So,…you been working for Nikon how long?
      (FYI, the Mad-Men Ad-Writer dialect is a give-away…)

  • Neopulse

    Hate to post something like this, but I think they should’ve patented a newer tripod mount instead of a handstrap that most people buy from a 3rd party anyways.

  • Photobug

    Nikon wants to sell hand grip straps…why?? There are lots of options out there already, some good and some not so good. I have tried two different brands and was not impressed with them. There are cheap to high priced. Doesn’t make sense.

    As far as the two lens…that is very logical and the 18-300mm would be a great general “one” lens….only if its sharp from 250mm to 300mm.

    Come on, what else will be announced next month…like the D400!

    • Calibrator

      > Nikon wants to sell hand grip straps…why??

      Well, Nikon sells watches with a Nikon logo. What do you think why?

  • 103David

    About the handgrip…Just looking at one makes it seem soooo useful. But the reality is they’re very uncomfortable, sweaty on a hot day and really makes it difficult to either pick your nose or scratch your ass while nobody is looking.
    Forget it, you have better things to do with your paws.

    • Ineluki

      So true.

    • Jose Maria

      Just get a decent shoulder strap.

  • Steve Wakeman

    Nice – It would be cool if the hand strap and at least one of those lenses came to fruition.
    Unlike the 16-35 f/2.8…. 🙁

  • neversink

    If I were to hike the Appalachian Trail, then I would buy the current 28-300 for convenience, and take along the 17-35.

    The IQ of the current 28-300 is questionable, not to mention the barrel distortion and pincushioning. ( I know the distortion is correctable with software if desired, but let’s say I am shooting film?) But can a DO design make the IQ of this lens better? At least the version I purchased at B&H last year was not as sharp as reviewers claimed, and so I returned it. Maybe I just had a poor sample. Or maybe I am too critical. But I found the 28-300 too soft for my taste.

    • 103David

      I would agree about the sharpness of the 28-300 and return it just like you…but walk the trail carrying the requisite minimum of a brick or two of Fujichrome?
      I mean…Seriously?

      • neversink

        A bit off-topic…. Can I have an assistant on the trail carry all my camera gear for me??? and my backpack as well?

        Seriously, what camera would you carry on the AT if you were hiking all 2,000 some-odd miles??? I would be tempted to go DX D7000 or D7100 with the 18-200 and one ultra wide angle lens. Not my first choice. A D800 would be my first choice with the lenses I suggested in my post above, but then the lenses are heavier than DX lenses. However I would carry all this in a smallish Kata hiking pack in front of me while the rest of my backpacking gear would be in my regular pack.

        Maybe just the Fuji x100s would serve me better, but I certainly would only get a fixed equivalent of a 35mm lens. I don’t think the Nikon 1 would satisfy me, except for the weight factor.

        • Calibrator

          When I’m on trips and can’t pack much I use a D7000 with the 18-200 and the Sigma 8-16, together with a GPS-unit that also works as a track logger. It’s a good compromise and covers all the range I would need with about 2 kilograms.

          Granted, the lenses are quite slow but I’m fairly sure that they would be quick enough for hiking.
          The 18-200 also isn’t the sharpest lens on the planet but how big will you print? I did prints up to 80×50 cm with this lens and was very happy with them. For slideshow presentations or websites it’s more than sufficient.

          No way I would leave the house without an ultra-wide, though, so any other system I’d consider would need such a lens. Sony NEX uses APS-C and now has a 10-18 mm, for example. Other system may not go as wide, though.

          If you want to reduce weight and the form factor then you could get a smaller Nikon body like the D5100 (=D7000 sensor) or the D5200 together with the Nikon 35mm F1.8. This would mean more plastic and no weather sealing at all so you should ponder about that.

          If you use a small mirrorless system like a Fuji or a NEX you should also take battery performance into account. Typically they last for about 300-350 shots – you’d have to carry three times as many batteries compared to the ones the D7000 uses…
          You should also think about how you will power the camera on such a long trip. Will you simply use lots of standard li-ion batteries, mobile recharging units or dedicated battery grips that support regular alkaline (AA) cells?

          Personally, I would think hard about going on such a long trip with very expensive equipment like the D800, perhaps a 14-24 and other expensive lenses – apart from the weight problem. Along the trip something could happen to your equipment (weather, accidents, theft/robbery…) so get a proper insurance and at least a waterproof SD card case in case the bag gets flooded…

          • 103David

            Many good suggestions, but would disagree with a few…I don’t particularly recommend an insurance policy as they tend to be expensive and troublesome in their own right, especially if traveling outside either your own country or the insurance companies country. Then there’s the deductible which begans to make the whole thing hardly worth it. Conceptually, always remember that today’s high-tech is tomorrow’s garage sale item. Don’t spend a lot of money on something that was already obsolescent when you bought it.
            On the other hand, the most expensive part of your travel expenses are for getting your warm body to wherever. The only thing you’re really going to take away is your memories and your photos. In other words, listen to Calibrator and get the water-proof memory card hard case as well as a sufficient number of memory cards to not have to worry about downloading to some flaky hard drive (inherently) unreliable device or another. The basic idea here is when Captain Renee decides to plant your liner onto the coast of Tuscany and it’s time to get out, take the cards, leave the camera.
            Trust me on this point…Been there, done that…don’t ask for details.

        • 103David

          All good stuff, makes the mind bend, doesn’t it? Over the last few years I’ve been traveling quite a lot, sometimes in dark places and I’m finding I don’t much mind a heavier body and lens, but I’ve drastically reduced the absolute quantity of equipment, meaning the accessory count. My overall burden is much lighter than “back in the day,” now that I don’t carry two motor driven bodies, at least four lenses and especially the aforementioned “brick or two…”
          Sticking with the D700 body for the moment, with truly formidable low-light performance, rugged, and I’m still waiting for Nikon to hash out the replacement FX sensor vehicle that I insist on. Potentially the D700 could be useful in some of the dark places for klopping one of the deserving locals, maybe.
          I’ve found the 70-300 neither too big nor too heavy and an excellent performer. Also the (now rather elderly) 20-35 f2.8. This last one has been a real gem for me. It’s fast, rugged (actually made in Japan) and somewhat smaller than the 17-35 f2.8. All have been extremely good, walking the Great Wall, the Terra Cotta Soldiers, and a Shanghai new Year’s Eve. Also the dark and demanding rain forests of Panama and Costa Rica.
          If I really need to pare it down, the D700 body and the newest iteration of the 24-120 f4.0 really do the minimalist trick. This lens is very sharp, and the wide angle, a fixed F 4.0 and close focusing make it plausibly fast for say, the interiors of Spanish castles and cathedrals. (Told you, been traveling some lately.) Add a polarizer and a spare battery in and you’re good to go.
          Oops, almost forgot, for this latest Spanish trip, I did squirrel a tiny little 20mm f3.5 manual focus lens just in case the 24 wasn’t wide enough…but never used it. It turns out, my latest IPhone in the panorama mode worked way better anyway.
          Remember what Galen Rowell answered when someone asked him the secret of how he shot all those great pictures. “Shoot everything at F8…and be there,” he said. Don’t sweat the equipment, but book the trip today.

    The Guardian said that’s the new D400 handstrap. It’s make using nano graphene tube technology using 3D printers.
