Advice really welcome as I have just bought a 10-22mm lens. Autofocus not as sharp as I thought but not sure if I'm expecting too much too soon. Some of the colours on some pictures are also a bit washed out.... Have got some sharp pictures on manual but not consistently yet! Also a number of photos have orange circle, always in bottom left corner which is obviously light related but seems strange, particulary the frequency with which it appears....
Unfortunately as I'm still learning I'm not sure whether this lens is a good or bad copy! Before I go back to the camera shop I would welcome any comments particularly if I am doing something wrong......
A mixture of pictures taken over the last weekend - good and bad - attached.
And what looks ok to me but would welcome comment:
