    So I was recently given a canon 1300d from a friend and have a sigma EX HSM 17-35mm f2.8-4 aspherical hsm lens, and a sigma EX HSM 70-200mm APO F1:2.8 lens. The problem is they're not compatible and was wondering if there was some kind of adapter that will make them compatible together, thanks.

    Do you know which mount the lenses have?
    There are Sigma lenses that can be remounted (not sure if that's the correct word) by Sigma, but that comes with a price ofcourse.
    But I think both mentioned lenses are not part of those. (the EX line is an older line of lenses) So if they don't have a Canon EF mount they can't be used
    You might need to get new lenses or a different body (if both lenses have the same mount)

    @Alex1998 do both lenses have the same mount? Then both are Sigma SA mount lenses. (looks like EF mount but is smaller)
    But both lenses are from the older EX line lenses, I'm pretty sure Sigma's mount conversion service will not be available

    (Fun part Sigma SA mount does actually use the Canon EF communication protocol)

    @Alex1998 Sigma's mount conversion service (Scroll down to "Service Overview") is only available for the Global Vision lenses (Art, Sports, Contemporary).

    I would try to post a side pic of both lenses with the printed name visible.

    Here is your mount Pic :
