My Quiet Life My Quiet Life


I am getting weird reflections like this on longer exposures with my camera. Any ideas what would cause this? Is it reflections off of a lens element? Is it normal? Does it mean my lens is just crappy?

These were both taken with a Canon EOS D30 with a Canon EF 35-70mm f/3.5-4.5 lens

UPDATE: Kenny was right – it gets better as I stop down the aperture. Example pictures here.

UPDATE 2: The consensus (minus a minor flame-war) on agrees with everyone here – that it’s just a common problem with cheaper lenses, made worse by the UV filter.
