This TeleConverter is too much for my Tamron 150-600mm lens used for birding and wildlife.  May work better for shorter focal length lenses

Lens probably only used about 5 times. Original intent was to us for night and regular photography, but focal length range was not good enough for landscape day photography without bringing another, lower focal length  lens (14-28mm). Ended up getting a slower Canon lens with wider range (28-300) for daytime photography.

Note: there is a hairline crack on the body, see image. #3 & #4
