That's not CA that's sensor bloom. The lens itself exhibits almost no
CA. Supposedly CMOS sensors have done away with blooming but I see it
all the time in lens reviews, refereed to as CA, because well, CMOS
sensors did away with bloom, but CA is almost always two color red/blue,
bloom is purple or just plain white. Now I'm going into this because
I'm really tired of seeing obvious sensor bloom in images and having it
be miss identified as chromatic aberration, they are not the same
thing. CA is caused by a lens defect, bloom can be exacerbated by
having a high contrast lens with even a very good sensor. Neither of
those things is a defect. The issue of removing the sensor bloom is
another problem, I've never successfully been able to do that. If it's
there I just live with it.

Matrix Metering was what I used.

I agree that matrix metering would help.

Odd. I use the full matrix metering on both the k-5 and k-3 when shooting
egrets, and I haven’t blown one out in recent years. Generally, white
objects will slightly underexpose because a dumb meter considers them
neutral. I’ve shot them both against a bright sky and against dark water and
shrubs. No blow outs. I don’t believe I used exposure comp on any of the
shots. I do shoot RAW and usually pull down highlights in conversion.

P.J. You don't indicate the focus metering. Could it have been other than
spot?

But three views. I always blow out the highlights, even dialed in -2
stops of exposure.
The first two are about 1/2 to 2/3 frame crops.
