    i think thats just using wide lens in a location with lots of straight lines shows up distortion you can post process the distortion or just go wth it.

    or shoot longer and make a panaorama with might be less distorted i think… got and example?

    Cheap compromise: correct it in Photoshop
    Best solution: buy a better lens :)

    What do you disagree with? I didn´t say it was cheap, I just suggested buying a better one (maybe TS-E 17mm f/4 L if you want to shoot architecture).
    BTW I´m pretty sure that you get exactly the same results outside or inside, you just don´t notice it because it´s hard to find straight lines in nature.

    Buy PTLens for Photoshop ($25 approx) and it should sort it out for you.

    could you post the picture?

    I have a sigma 10-20 and at 10mm a landscape looks natural(ish) but shoot that in a archetectural setting and can produce mindbending results… :)

    I think thats normal for the lens looking around on google reveals it does distort a bit but its nothing to get worried about.

    your point of view for the image exagerates it if you were square on to the couple the image would look less stretched but the moment wont always allow that etc.

    use pt lens or the default lens correction tool in PS or PS elements can fix it or even just do a bit of a transform adjustment would fix it abit has to be said the walpaper and floor boards dont help either :)

    Hope thats some help

    thanks for all your feedback
    i tryed abit of free transform which has corrected it
    i was mainly worried the lens was faulty.
