Pentaxpastor's reviews

  • Tamron 70-200mm f/2.8 Di LD IF Macro SP AF

    9 out of 10 points and recommended
    Great build, super sharp, great macro performance
    Slow autofocus, tripod collar

    This is the best lens in my bag on many counts. It's sharp as a tack and consistently takes incredible pictures. I also have the much cheaper, but also well rated Sigma 70-300 APO 4-5.6 and there is no comparison in the pictures from the two lens.

    Like all lens, this one won't make you a great photographer, but it certainly does provide a photographer with the quality glass necessary to take exceptional pictures.

    While not a true macro lens I especially love the close ups this lens takes, they are remarkable. The primary subject will be tack sharp and the background will have that truly beautiful dreamy bokeh.

    A downside of the lens is that autofocus is not fast and at times the lens will hunt for focus. I love being a Pentax shooter, but on my K10, this isn't a great lens in that regard. The K10 is a bit slow to begin with and this lens magnifies that. I hope it becomes less of an issue when I upgrade to the K-7 shortly.
    My only other complaint is that while the tripod collar is well made, it's not quick on and off and the screw can cross thread even when I'm being careful.

    I would probably buy this lens again, but after owning it for 9 months, would also take a close look at the Sigma 70-200 2.8 just because focus is stronger on that model. However, the Sigma doesn't have the great macro performance this lens does, so I would probably end up at the same place all over again because this really is a great lens.
