    It is probably a straight forward question,but I can't think why all the raw images shot with my OMD are at a much wider view than the JPEGs and the viewer image.
    Obviously the lens has a two x crop,but that surely isn't the only answer as I have taken Raw and JPEGs with many other cameras with the same field of view
    Can anyone help?
    Thanks

    Which RAW converter are you using? If it is a RAW converter that does not apply built-in lens corrections, you will see the uncorrected image which in many cases will give a wider view.

    Could be but how does the raw image get a greater possibly double field of view,not provided by the lens
    Raw editor is Adobe

    Only thing I can think of is maybe you're shooting at a different aspect ratio in JPG, and it's automatically cropping in camera. Double check and make sure you're shooting at native (4:3) ratio in JPGs and not 3:2 or 16:9 that's cropping the image.

    Which Adobe product, may I ask? Only the RC of LR 5.3 has proper RAW support for the E-M1.

    The reason that you see a larger field of view would be that the correction of barrel distortion involves cropping the image, and the lens is made wider to take this into account: this is particularly prominent on the Olympus 17mm f/1.8.

    An alternative possibility is that you are using the "digital teleconverter", which simply crops JPEGs to the middle part of the frame.

    Do you have a different aspect ratio (e.g. 1:1) selected in the menu (see page 55 of the manual)? This would be applied to the JPEG and viewfinder, but not the RAW file.

    [like Jay said :smile:]

    Oh, I forgot about the digital TC - that's another definite possibility, if this is a large crop we're talking about here.
