    Wow, when comparing this to Nikon 80-400 at 1570g, this 1.1kg lens is amazing in terms of weight. Obviously losing 20mm against the Nikon. Is the weight saving in the glass? Although no details have been given yet. Am sure most will want to see if the weight saving has lead to any sacrifice in image quality against the Nikon 80-400. But for event work, shedding 400g is a blessing to my feet 🙂

      I think Nikon is a bit lighter without tripod collar and is also faster at longer end… This Tamron should be no match for much more expensive Nikon but it is light and handy and focus much closer and if price is right and AF reliable it will blow similar Sigma lens away…

      • Jacob Smith

        Don’t count your chickens before they hatch. No way of telling if the Tamron lens is going to be slower than the Nikon lens at the far end until its tested.

        • MB

          Nikon is f5.6 vs Tamron f6.3 at 400mm … in photography it is called being faster, I presume it is different with chickens 🙂

          • TurtleCat

            It is, although granted 1/3 stop or whatever is not a big deal. I wonder at what point it becomes 6.3?

            • Jacob Smith

              4.5 at the wide end and 6.3 on the long end.

            • TurtleCat

              Yes, but at what focal length does it change to 6.3 is what I was saying.

              hahaha clueless

        For me the tripod collar will always be on for events as my carryspeed attaches to that point to maintain balance of the lens+camera. Its good to have arca swiss option as well, as currently I need to attach an arca plate to Nikon’s lens.

    • JXVo

      The weight saving is in the f6.3 maximum aperture at 400. The Nikon 80-400 is f5.6

    Admin, just dropping in for a typo mention. 🙂
    The invitation line just below the last photo says “going” instead of “join”.
    Sorry, couldn’t help it – I used to be a proof-reader a decade ago.

    Can’t wait to see how this lens does. I currently own the Tamron 70-200 and 70-300 and this would be a nice upgrade from the 70-300.

    “Magnification: 0.2777777777777x”
    What is this referenced to? I thought FX mag was referenced to the 50mm as a 1x standard. Therefore this would be a 2x-8x mag.

    • TurtleCat

      It’s probably the closeup ratio.

  • Tieu Ngao

    Compared with the new Sigma 100-400mm f/4.5-6.3, which is quite a good lens according to various reviews, this Tamron has an advantage with the optional tripod mount (the Sigma doesn’t) if the IQ and price are similar (size and weight are).

  • bobgrant

    Just get the incredible Nikon 200-500 and you’ll be very happy. I also own the Tamron 70-300 and it punches way above its weight, but the Nikon 200-500 only compromises by being really big.

  • JXVo

    1/3 stop is a bigger deal than you might think for the wildlife shooters who get their best opportunities early or late in the day. Long lenses like faster shutter speeds and every little bit counts. In less than optimal lighting this means shooting at ISO 3200 instead of 2500 which is a practical noise threshold for many FX users, or SS of 1/500 instead of 1/640.
    In good lighting not really an issue.

    • Jacob Smith

      Not really. I shoot many genres including landscape and wildlife. With a third less stop of light you can still photograph the wildlife a little underexposed and correct in post. Also its not just the lens itself but also which body you’re using with it. A good camera body will compensate for the loss of light shooting at 6.3 instead of 5.6.

    • Mike

      I think if you’re riding that fine a line and its critical you get the shot…. best to get a much faster lens, no?

      • Jacob Smith

        No. Shot a ton of wildlife at the but crack of dawn where a 1/3 stop of light didn’t make any difference but not worth spending 3 times as much just to get that 1/3 stop of light.

      • JXVo

        Yes, which is why I did exactly as you suggested…long ago.

  • I wonder what the new Tamron 100-400 will do if paired with a Nikon D850. I like the idea of a lighter lens I could carry all the time. I rented the Nikon 200-500 months ago and loved it, except for the bulkiness and weight that makes it impractical for me to carry often. (I’m 69.) I hope to upgrade from my current Nikon D610 for my landscape and wildlife hobby in the next few months. I want something with some reach but easy to carry. I have high hopes for the Tamron 100-400. Right now, my Tamron 70-200 G1 is my favorite lens.

    • MonkeySpanner

      If you want reach how about a d500 with these longer lenses?

      • If I was only interested in wildlife shooting, the D500 might be a great choice for the reason you mention. I upgraded from a D7000 to my D610; so I know the difference full frame can make … and I like full frame better than crop sensors. The D850 has a crop mode equal to the D500 in megapixels and when in full frame mode it is 45 megapixels, great for detail in landscapes. The D500 shoots faster though and that can be helpful for moving animals and birds. Either camera is a bit of a compromise, given my interests. But I plan to stick with full frame.
