    The equipment is a Canon 80D body with a Tamron 18-200mm F3.5-6.3 lens. Sometimes while shooting, before the lens focuses the image seems to "drop" a little in the lens. I know it's not the best lens. But what could be causing this? Is it just a crappy lens? Can it be fixed? Is it damaged? I've only noticed this happen in auto focus and doesn't seem to effect the image quality.

    Thanks for the reply.
    Is it normal for the VC to do that?

    all stabilizations ive used make the image in the viewfinder "move" as they engage... this is also why they say not to use it on a tripod and fast shutter speeds; you'll capture this movement.

    Yes, VC or VR egaging, on some lenses, can do this image shift or image drop; it depends on the specific lens design, but my old 80-400 did that to a significant degree. It's normal behavior on some lenses, or in some types of image stabilization; not all image stabilkization systems or modes do this top the same degree. It is NOTHING to worry about though!
