  • Sigma 120-400mm f/4.5-5.6 DG OS HSM APO

    5 out of 10 points and not recommended
    OS 4 stop, HSM, ring tripod, price
    weight, soft and... I have a big problem: front / back focus. Not good!!!

    good OS 4 stop, but less than IS canon, much slower and noisy to stabilize the image.
    Very soft 400mm f 5.6 !!!
    medium sharp 400mm f/8 and f/11.
    Bat I have a big problem for front / back focus to send assistance
    SIGMA to adjust

    With Canon 450d = 192mm - 640mm
    With Sigma Teleconverter x1,4 or x2,0 AF does not work.

  • Canon EF 100-400mm f/4.5-5.6L IS USM

    9 out of 10 points and recommended
    Construction, sharpness f/7-f/8, 400mm

    For me it is very professional and easy to use!!

    I had the new Sigma 120-400 but the canon is far superior in clarity, weight and construction.
    The lens is metal but it is very light and handy.
    the IS with 2 stop working very well, better than the 4 stop the Sigma. The best sharpness is a 400mm f / 8.

  • Canon EF 50mm f/1.4 USM

    9 out of 10 points and recommended
    f/1.4, price, light.
    plastic body.

    This lens I use only for the interior and dimly lit with af/1.4 is really fantastic.
    The best quality you have to f / 4 to f / 8.
    I used this lens all over the world for me money/quality is 10.

    This is the only f/1.4 canon lens-economic.
