    Default Lens problem...

    hi guys,

    My friend recently gave me his old Canon 5D (not Mark II). So I went online to find myself a lens, and after much comparing, decided to get the - Tamron 18-277mm F/3.5-6.3 Di II VC PZD lens which had gotten pretty good reviews. It says it's "for Canon", so I noobly figured the two are compatible. Then the problem comes...there's no issue mounting the lens, but when I look into the viewer, i see a dark ring around the 4 sides of the images, so my images...not sure how to describe it...look like they're taken through "tunnel vision"?

    Is this a matter of wrong lens? or there's something about the setting?

    Please help!

    Thanks!!

    noob

    you are using a lens design for crop sensor on a full frame body, the image circle of the lens are not able to cover the whole sensor. in short, this lens is not compatible.

    There are lenses for crop body & full frame body. Canon 5D is a full frame camera.

    As a newbie, photography can be very bewildering, especially on the technical side.

    With dSLRs, the following terms relate to the camera's sensor, or eye.

    • Crop sensors (APS-C)
    • Full frames

    These basically means the ratio of crop, or in the case of full frame, no crop involved. A crop factor is "related to the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference" (referenced from Wikipedia.org).

    Canon markets its dSLRS according to this line:

    Model Series
    Type
    Usable Canon Lenses
    EOS 1*
    EOS 5*
    Full frames (with exception of some models being APS-H) EF series
    EOS 7d Full frame sensor, but with an APS-C crop factor EF series
    EF-S series
    EOS xxd
    EOS xxxd
    APS-C sensors EF series
    EF-S series



    As such, whenever you want to buy a lens for your camera, the general advise is to bring your camera along with you to test it, else you'll be kicking yourself for not doing your homework.

    Cheers!

    I hope the information is helpful, and is as accurate as to my knowledge, and also thanks to Wikipedia.

    Hi Dingaroo,

    Thanks especially for the above! Would just like to check further - does this then mean 7D is able to use lenses meant for both "full frames" and "Crop" sensor cameras? In actual usage, is it an automated process (for body to determine lens type), or are there camera settings that need to be adjusted?

    yes 7D is able to use lenses meant for both "full frames" and "Crop" sensor cameras

    As a general guide of rule,
    "crop" cameras can use all lenses for "full frame" and "crop" lenses
    "full frame" cameras cannot use lenses made specifically for "crop" lenses... for Canon it's the EF-S range(eg EF-S 18-200mm) , for Sigma it's the DC range( Sigma 30mm f1.4 DC)

    since i didn't spend money on 5D, think will just try to sell it off, top up with some money, and get a 7D!

    Read carefully again: 7D has a crop sensor, meaning: the sensor is smaller in terms of physical dimensions (go to www.dpreview.com, check both cameras, read the details about sensor size, it's given in Millimeters). Therefore, the 7D model can use lenses designed for crop sensor and also full frame lenses. The 5D model, being a full frame body, required the respective lenses mandatory. There are no camera settings that would enable a Canon full frame body to make use of lenses designed for crop sensor bodies, period.
    Unfortunately, some 3rd party makers are not that clear in their descriptions. Here it helps to read "Designed for Digital DSLR" = "Designed for crop sensor bodies".
