    400mm f5.6? That’s impressive, I’d have expected at least f6.3. It’ll be interesting to see if Tamron manages to retain half decent image quality. Their 16-300 is surprisingly good, so it’s not impossible.

    • Ashraf Al-hujaili

      well, if you look closely on the lens itself above, it is 6.3 at the long end, i think this is a typing mistake

      • Manfred Grebler

        Yes, 400mm f5.6 is impossible with a 72mm filter.

        • HD10

          As the exit pupil is 71.4286mm, it would be very interesting if Tamron can pull that off. This is not likely however so indeed, there must be an error in the specs.

        • JXVo

          Both the Nikon 80-400 versions are marked f5.6 at 400mm with a 72mm filter thread but I agree, the math doesn’t pan out when you take into account that the front lens optical diameter will be somewhat less than 72 and further aperture restrictions probably apply deeper in the lens.

          Lens manufacturers tend to round the numbers down quite liberally. They can also be quite liberal with the true focal length numbers.

          • El Aura

            Their have been 400 mm f/5.6 primes from Sigma, Tokina and Nikon with a 72 mm filter thread. Though, all else equal, zooms tend to be a bit bigger than primes.

            • JXVo

              The Nikon 80-400 lenses, both versions, use 77mm filters. This means the front element can be big enough not to be the aperture limiting element.

              A lens with a 72mm filter thread will have an internal diameter at the front element of somewhat less than 72. Anything smaller than 71.43mm will limit the aperture to smaller than f5.6 at 400mm focal length. Of course, other lens elements and internal components can have smaller effective apertures and become the limiting factor….such as the aperture diaphragm when stopped down….

        • jojo

          Technically, yes; but both numbers will be approximations. A 400mm f5.6 lens could be 382mm f5.82, or whatever. And as others have noted, this 5.6 figure is a mistake.

          • nwcs

            Yes, I think people forget that most of these specs are effectively rounded off while focusing at infinity.

      • Bob Thane

        Ah, that makes more sense. Cheers!

    I might get the 18-400 if reviews are good. It would be a good one for my D500 as a walk around lens

    • sickheadache

      Nice pocket lens..u happy to see me?

      • Fly Moon

        Or just a small bag. Cameras don’t have to be pocketable

        • sickheadache

          Relax ….U got the Job.

          • Fly Moon

            Why are you angry?

  • ValenzTa


  • ValenzTa

    Fx or DX for Nikon?

    • Mr Majestyk

      DX, since it’s a Di II lens.

  • onthedot

    Anxious to see how the 24-70mm holds up against Nikons version. While Nikons version isnt perfect (barrel distortion and all), there is something magical about the images it produces.

    • Eno

      Yes, “there is something magical about the images it produces”, the price per image actuation is very high. :))

      • onthedot

        Not if you charge enough to pay off the lens quickly.

    • Nikos Skartsilas

      Fully agree. Plus uniformity and consistency, things absent from (previous at least) Tamron which also gives strange overexposure at wide apertures and a real slow af.

    • bushkov

      Anxious to see how the 24-70mm holds up against the new Sigma 24-70.

    • pyktures

      It’s the glass compound being used in Nikkors that helps to keep the contrast and the color saturation. Tamrons tend to render milky but sharper.

      • Spy Black

        …unless you look closely at the edges…

      • onthedot

        From what Ive seen, the colors seem colder with most Tamrons.

  • Mr Majestyk

    Minor disappointment with the 24-70, worst in-class max magnification of 0.2x,

    • Ande Notos


  • TinusVerdino

    Everything is the same about the 24-70 except .5 stops more stabilisation and it weighs more. (And appearance f crs..)

  • I would still prefer if the lens hood is not attached to the front barrel.

  • EarlFargis

    I have the current Tamron 24-70 and it’s the lens I use most. It’s quite good with distortion easily corrected by software. So I’m very interested in seeing how much improved this update is.

    When I bought my Tamron it reviewed favorably to the previous version Nikon 24-70. So my expectations are high for the update. Of course, it will be considerably less expensive.

    Sigma at the time didn’t offer a very competitive 24-70, imho. They’ve announced an Art update to the ‘meh’ EX version. Obviously, Art lenses have a well deserved reputation for upping the bar. So I should probably wait to see if Sigma has figured this focal length out better than their rivals.

  • Robbie Green

    I have the current Tamron 24-70 f/2.8. It absolutely blew the Nikon 24-70 f/2.8G that I owned before it out of the water in terms of sharpness, and the VR is nice to have too.

    It will be really interesting to see how much or if Tamron raises the bar with this one. Could be a largely cosmetic refresh.

  • roadie

    I just purchased the current Tamron 24-70 f2.8 a few weeks ago. Now I wonder if I should return it and wait for the new one..

    • scott800

      If you can return it without consequence, i certainly would. You could probably buy the same one for less once the new model is released, or get the newer model which will likely hold its value longer

      • roadie

        The price already went down for about $100 when I purchased it. My version is also made in Japan. Not sure how much improvement the new version would have, plus the new version will be made in China..

      • roadie

        Optically the current version is very very good. In most ranges, even wide open, the sharpness is higher than the 50mm 1.8G, 85mm 1.8G, and 70-200 f/4. The contrast is not as good though.

        • Chris

          Get the new one. I tried tamron’s old 720 a while ago. New coating used in recent lens are WAY better.
