  • Tamron 200-500mm f/5-6.3 Di LD IF SP AF

    9 out of 10 points and recommended
    Very sharp 200-450. light weight
    Slow AF with my Eos 20D, corner sharpness

    I started dSLR two years ago as a hobby.
    Telephoto is not my favorite, so Tamron 200-500 is my first and only telephoto experience. This len is also my first 3rd party len.
    I got this len one week after Christmas. It is very sharp from 200 to 450. Sharpness declins at corner rapidly of the picture.
    I had no chance to test outdoor since there is raining almost every weekend. I tested indoor on 5 meter s far from subject with flash on, I love the results including at 500 zoom. Handheld is perfect.
    AF is slower than other my canon lens on 20D.


    Before I bought this len, I decided between fixed lens (canon 300mm f/4 L and 400mm f/5.6L) and Canon 100-400L. I prefer zoom over fixed lens (even they are sharper), then after compared many reveiws between tamron and canon 100-400, I final with tamron with a cheaper and an extra zoom. Canon might sharper, but tamron is sharp enough for my test. :)

    I am really happy so far. I am waiting for an outdoor test.

  • Canon EF-S 10-22mm f/3.5-4.5 USM

    Almost perfect!
    Bad results when UV filter on

    I really love love love this len. It's on my Eos 20D all the time. Sharpness is really good though not the best. Excellent image from 14-22 zoom. (10mm sharpness is not my favorite). AF fast, night shot and indoor with no flash are very good, close up also give a good pictures. Not recommend for portrait photography. I love taking pictures of painting with this len over 50mm f/1.4.

    I have some issue with UV filter (sorry H_YA). My outdoor picture sharpess was down sicnificantly, but indoor was still good.

    Indeed, perfect all around for me. Yet depended on your preference.
