    pretty long though Focussing speed feels quite alright on the 20D but it's hard to hold it steady (900mm equivalent field of view!!!).

    Particularly like to know the feedback on the 200-500mm.
    It is well worth the $1750 to get 200-500mm as compare to prime lens @:
    200mm ($1~2k)
    300mm ($2k~7.8k)
    400mm ($9k~10k)
    500mm ($10~12k)

    Although the aperture is f6.3 @ longer end...but increase the ISO will solve this problem if u are using CMOS sensor...

    Sigma has a 50-500 that's pretty good too.

    Impress with Tamron lenses, some test shots
    here.

    Lenses tested were:
    1. 90mm Macro
    2. 17-35mm
    3. 28-75mm

    Can't resist the temptation..

    Yes read a lot of good review on the bigma. But so far very few review on the tamron, let alone a 1-to-1 comparo.

    also, bigma's actual max focal length is only 465mm, while tamron is 486mm.

    hence still cannot decide yet.

    Had a chance to try out the tamron 200-500mm with a Nikon D70 here are some pictures.
    (lens was mounted on a tripod)

    The first is from a 50mm


    200-500mm @500mm


    Crop of the above


    Tighter crop


    Hope this helps.

    You da man!! Thanks again for letting me try all you lenses the other day. This is a picture of one of my friends with the lens. Can you spot the puny 350D in his hands?


    Is that a Tamron 200-500mm or are you just pleased to see me?
