    Hi guys

    I'm fairly new to photography,I've found a Samyang 8mm F3.5 Fisheye for sale and cheap but it says it's built for a camera with the APS-C sensor.I have a Canon 1100D which has a CMOS sensor and I'm wondering would I be able to use it with my camera and if so would there any difference?

    It just means cropped sensor. So yes, your canon 1100d is fine.

    Some landscapes shot with that lens can be seen at the above link.

    APS-C is the generic name for sensors which are approx 1.5-1.6 crop factor in size - like your 1100D. A CCD sensor can also be APS-c in size

    http://en.wikipedia.org/wiki/APS-C

    CMOS [b]C
    omplementary Metal–Oxide–Semiconductor] is the name of the technology that your sensor uses - as opposed to a CCD [Charge-Coupled Device] type sensor.

    Each technology has advantages and disadvantages:

    Totally.

    The D7000 also has an APS-C sensor.

    The Samyang is a very good lens.
    It comes in various manufacturers mounts and for SLRs and 4/3rds camera systems (just make sure it is the right one for your camera).

    Just don't expect it to auto focus - it is a manual lens for both focus and aperture.
    Don't let that put you off though, it is very well made with a metal lens mount (more than can be said for some much more expensive makes) and has much less distortion and chromatic aberation than you would expect for a lens of that price.

    I have the 7.5mm vertion for the micro 4/3rds Lumix and Olympus --- there are a few on my portfolio page going back 6 weeks.

    I wouldn't worry about any focusing problems with a lens this wide, its own inherent depth of field virtually guarantees that everything will be in focus.
