Default Big Old Lens on new body

Just recently had the first opportunity to try out my good old SMC 135-600 on the new (to me) K20D.
Manual focus seemed a bit easier (brighter viewfinder than the KM).
It also seemed to show a little less of its amazing chromatic abberation. Do different sensors have different CA tendencies?

Here are a few samples - all with only minimum PP (no correction of CA) and minor cropping for composition purposes only.

First some shots of a rather shy Black Crowned Night Heron. Has been hanging around the same stretch of lake most of this summer, but very difficult to approach. Took a bit of stealth and stalking (not so easy with giant lens and giant tripod!) to get closer...

His big cousin, Great Blue Heron, is also usually shy. But we have a few very bold juveniles who don't mind lenses pointed at them...

Here are some "up close and personal" shots. Still look to me like not nearly as much CA as with the KM - what do you think?

And now for my favorite "big bird" subject. Home park is host to a lot of Black Vultures, and they are always so cute and photogenic!

Just a few shots of another Heron. These were taken with the A* 300, another lens I haven't used much with the K20D yet. This is a juvenile Green Heron, hanging out not too far from the first heron's favorite perch.

Would really appreciate any input on these, and also your thoughts on how different cameras handle the (good & bad) effects of lenses. Thanks so much!

G'day Mole

I think most if not all those images could grace any book on American Birds
Too many images to be picky with ... no CA that I can discern on my laptop screen

Regards, Phil

Nice sharp images Mole, the detail in the Black Crowned Night Heron is amazing, that SMC 135-600 looks like a nice lens, I will have to keep an eye out for one. You are correct CA seems to be under control, I have seen a similar reduction is CA going to my Kr from the Km. How does is that 135-600 hand held.

Hans - Thanks for the very helpful comments. It is indeed a fine lens, but rather a beast to handle. Have never tried it handheld - it's almost 2 feet long, and weighs almost 9 pounds!
Here are a couple of shots to show you the size:
