    Sigma 50-500 APO DG OS - First impressions

    I got this lens (Canon fit) on Friday night. I have not had much chance to get out with it as the weather is a bit disappointing for photography.
    The lens looks nice and feels good, but the first thing I noticed was the knob for the tripod ring. This ring can only be removed when the lens is NOT attached to a camera and the knob is annoying. It is close to the "grip" and gets in the road.
    This tripod grip is not as good as the splitting "new type" (with the longer 'foot') that I have on the 120-300 f/2.8. It is probably safer, and I shall learn to live with it.
    The zoom ring is stiff. However it does creep if the lens is pointed down. I did not thing it would, being that stiff. I guess it will loosen up a bit. It is a pity that the 'Lock" swith only works in the 50mm position - 500mm would be nice too.
    Focus is fast, and unlike my friend's 150-500 the OS motors are silent - literally silent! The image does jump when the OS kicks in - less than 1 second I reckon - and it can be difficult to get used to re-framing slightly. The image wants to stay where it was!
    The focus on this one is virtually spot on straight out of the box. I gave it a quick check and took a few pics without any microadjustment at all. The images in this post have been Photoshopped, but nothing extra-ordinary.

    It is dull and raining here again this morning, so I guess I will not get out today.

    I shall add to this post as I get more experience with the lens, and find more likes and/or dislikes.
