I'm new to this forum and hope this is the right place for my question. I've been out shooting my new EF 500 f/4L IS II with a 1.4 TC the last days. I've noticed strange artifacts/shapes in the specular highlights caused by the sun on water. Has anyone here seen the same artifacts with that lens or can assure me that this is a normal phenomenon? These highlights are rather distracting and I just want to make sure if this is normal or something I have to have checked out by Canon. Attached are two of the more prominent examples. These are just 100% crops of the embedded jpg in the raw file, no post processing. Both at f/7 and 1/1000s. Any help/reassurance/info on this appreciated.
Thanks in advance,
