Sigma 100-300mm f/4 EX IF HSM APO User Reviews

9.0/10 average of 3 reviews Build Quality 10.0/10 Image Quality 8.7/10
  • 8 out of 10 points and not recommended by (1 reviews)
    Built like a tank, fast focus
    Optics could be better, bokeh

    Let's start with pros - I really like the build quality of this lens, which is unusual for Sigma. It's built like a tank, metal barrel, zoom and focus rings operate very smooth, nothing to fault here. Also the autofocus is really silent and accurate, another plus for Sigma.

    Now what I didn't like: sharpness is ok. Not great, but usable. CA's (it's not true APO lens after all) as well. Completely useless as a portrait lens - while f4 is fine at 300mm, having the same at 100mm means that the DOF control is rather poor, also bokeh is simply horrible.

    All in all it's not a bad lens, however it can't compete with 70-200 f2.8, especially stabilised ones.

    Sharp, good range, solid build, fast and accurate autofocus.
    No IS/VR and the lens is a little heavy but that's to be expected.

    I bought this lens a few years ago after reading lots of reviews. From what I had read, it appeared that this lens is comparable in image quality to Canon's telephotos of similar zoom range. Well after owning this lens for three years and using plenty of Canon's lenses during that time, I can say that this lens really is as good but at a much better price. I have been extremely pleased with its performance. So far it has survived three camera bodies (20D, 40D, and now 5D2) and it's still going strong.

    I mostly shoot landscapes with the camera mounted on a tripod so the f/4 aperture is something I don't have to worry about but I can see it being of some concern for sports photographers. Also, the lack of image stabilization can make it a little tough to use handheld. Other than that, I have nothing bad to say.

    Here is a gallery full of images I've taken with it over the years:

    This lens is worth every penny.

    sharp, well built, fast focus, works well w/sigma 1.4x TC, price, fx/dx frame
    heavy, 82mm filter size, under-rated

    nikon doesn't really have an affordable fast focusing super-tele-zoom like canon's 100-400L. this is a great alternative because as a previous 100-400L owner, this one seems like it's as sharp with the sigma ex dg 1.4x teleconverter (TC), stopped down to f8 at 420mm. the color and contrast are excellent. don't use a kenko 1.5x or generic teleconverter. the 1.5x doesn't focus with it most of the time. the sigma 1.4x ex dg focuses slower than without a TC but still fast enough for sports and wildlife. i use this on my nikon d300 and d700 with a auto focus fine tune of -4.
    i highly recommend this lens. it's very under-rated - a sleeper lens.
