Flare or CA on the 105mm VR

Check out the frog's right eye. I'm not sure if this if some byproduct of
the frog's eye or if it's flare or CA from the 105VR/TC combo.

Looks like a specular highlight.

Thanks. That makes a lot of sense since I have seen a few patches of blown
highlights on the frog as well as the log when I chimped. I was using fill
flash and I think the blown highlights are the slivers of sunlight that made
it through the tree canopy. I haven't seen the purple in my other pictures
and thought that I might have a slight problem developing.

Re: Flare or CA on the 105mm VR

It's a small blown-out area caused by a direct spectral reflection of
the flash from the eye. The color fringing is the result of the
overexposed area affecting adjacent pixels. This is the same effect one
sees with tree branches etc. against a bright sky. It's not CA.

The purple reflection? If you have photoshop & a raw file, try the CA
slider to find out, I suppose it's flare or just some purple in the
frog's eye. Doesn't seem like a problem to me.
