    Hi All,
    I am new to this forum .Please advise on this.
    I am using canon 1100d with Tamron 18-250mm lens & i am planning to buy teleconverter for my Tam 18-250mm lens.
    could you please help on this, which teleconverter will be compatiable (Tamron 1.4x or 2x) for my lens?

    Regards
    Mano.

    The tamron would have poor image quality with an extender and although 500mm sounds attractive the resulting pics may dissapoint . Also you will loose AF .

    Your best option is probably cropping and up scaling the image size

    I just sold a Sigma 1.4x converter on Ebay, and the buyer came straight back at me complaining that it was incompatible with a similar lens to yours.

    Don't even bother trying, even if you can find one to fit result are going to be poor to terrible especially as you will have to manual focus though what will be a pretty gloomy view finder.

    Don't bother even trying, the image quality will be awful, the autofocus will not work, some teleconverters will damage the rear element of your lens.

    Unfortunately there is no cheap solution, if you are really serious about bird photography you will need to spend a lot of money on a long lens. The cheapest option is probably the Sigma 50-500mm zoom, but even that will set you back 1,000

    To add to whats been said a convertor will not work
    There is however the option of getting closer to your subject by using a little fieldcraft...which is food for your required subject Wink
    I quite often use a 100mm lens for bird photography because I know where my subject will beWink
    If you are saving and want a longer lens then for 1000 you wont buy any better than the Canon 400mm f5.6L Usm which is far better than any sigma or tamron variantWink

    Hi Mano. The Canon 400 mentioned above is an excellent lens and used by many. However, you could do a lot worse than trying the Tamron 200-500 lens. I photograph a lot of wildlife but in the UK birds come out as most available. The Tamron has been my most used lens by far for the last 6 years and has taken tens of thousands of photographs through 4 generations of Minolta/Sony cameras.

    It is an excellent lens for the money Mano, around (in UK) 2-300 cheaper than the Canon and has the zoom factor if the target is moving around.

    Denis.

    ive always wanted to use this kind of lens myself liking wildlife photography.can someone put to bed an old rumor on these lenses please.
    the sigma 50 to 500m with vibration reduction apparently has a really poor quality lele end ie 350 to 500mm .which I think if true is a bit of an design overlook seeing its damn likely that this is the most used range of this lens type.vrs
    the tamron no vr but sharper but not triffick so unless you get back to shutter /to lens lengths basics you image shake makes it an even worse lens to go for.
    so in my frustration I bought neither and hire a Nikon 200 to 400mm lens on the odd days I need it.
    however ive heard good news again about a new 80mm to 400mm Nikon out anyone know reports on this one
    regards thundy
