  • Distance isn't an issue

    The existing 70-200mm F/2.8 is sharper than the Nikon’s version which is due to be replaced by 2017. I hope Tamron also replace their 70-200mm f/2.8 and look into something special for 300mm or 400mm F4 primes.
    I am just reaching this stage where I am ready to start splashing some cash on lenses and Tamron is tempting if they can give some love in the telephoto-handholding range.
