    Sigma APO DG 70- 300 with a Tamron 1.4X SP AF TC

    Hi guys

    Felt the need for some extra reach
    So picked up a 1.4X TC, this is on a 350 D so effective focal length at 300 mm is 720 mm
    I couldnt find any info on this combo, so am posting a couple of shots
    AF does work but is very slow in low light
    Manual focus is pretty decent
    Unusable with out a tripod

    Both shots taken at f8, iso 400

    1/60



    1/2000


    Check out my flickr page for larger images
    What do you guys think of this combo?

    Just nit-picking... but it "only" amounts to 672mm
    What does it look like in full res? How sharp is the combo still?

    Drama,
    Nice shots. How's the focus without the TC?
    I have to bite soon on either this and a Kenko TC or the 120-300 2.8 and the TC.
    I really want the 2.8 but $$$$$$$$

    I'm pleasantly surprised, but I guess you are 1-stop down from wide-open.

    Without the TC: In good light, its fast & accurate but pretty useless in poorer light
    With TC: Pretty much the same, but sharpness is not as good

    I pretty much tend to use it at F8 most of the time, will try some f5.6 shots soon & post

    I was surprised by the sharpness too, not too bad at all at full stretch
    The extra reach is a blessing in crowded city scapes

    Thanks CWPhoto
    I liked the colors & the sharpness on the palm leaves myself
    A bit too dark perhaps?

    Not from here, perfect. The darkness saturates the colours.
