As others have said, there is no firmware update for the K100D Super camera. The K100D is a different model for which there is a firmware version 1.02 but it will not work in the K100D Super, which is probably why you are having trouble upgrading.

I've used the DA* 50-135mm for winter indoor show jumping events with good results, good enough that some of the images sold anyway.

It'll be fine.

Looks like decision made, go for it.

This shot taken with the K-5 II + Sigma 70-200mm lens would have been impossible with my K-5. 1/25th sec, f8, ISO 800. (Yes, 1/25th sec, it's not a typo).

The car is travelling at about 50-60 mph at this point. It took me almost 2 years of practice, and spending money on the right gear to get decent shots in rubbish conditions.

The blown out blob in the background is the reflective vest of a marshal.

I switched from K-5 to K-5 II for dimly lit nighttime motorsport and I can say that the low light performance of the K-5 II is vastly superior to the K-5.

I also believe the same improvement applies to the K-3 over the K-5II/s.

To answer your quandary, if you have the money, K-3 is a no brainer. K-5 II's are dropping in price so if money is tight, upgrade to a used K-5 II/s.

If Money really isn't a problem . . . got any lenses going cheap?

It looks like CA to me yes. But the question then is can anything be done about it, hence the interest in trying CA correction against the raw.
Lightroom's CA removal option removes the colour cast around the edges, but replaces it with grey.

Unless a new form of colourless CA had appeared
That's possible. Taking the hole in my first crop shot as an example where part of it shows green and the other magenta, there are also parts that are grey.

So, either the grey parts contain both green and magenta, therefore cancelling one another to produce grey, or they contain neither, leaving only the grey ghostly 'halo'.

Bearing in mind the magnification required to see it, I don't think it's such a big deal. I've seen a lot worse.

I have the full image. I've shown the worst affected areas, cropped only, no other processing, and included the full image. What else would you like to see?

Take a look at the hole in the rock in the cropped image, it shows a definite green tint on about half its circumference and magenta on the rest. Do you not think this is chromatic aberration?

Mike sent the image to me and in my opinion, it's CA, there's a very definite green tint to some edges, but not all. It seems to me that where the background is blue (sky), the foreground rock edge has a green tint and where the background is white (cloud) the edge CA appears grey.

Crop near the top of the left hand rock.

Excellent images, well done. What makes you think you need to use a wider angle lens? Were you shooting at 150mm mostly?

I can get much closer to the action for my motorsport images (oval track) and I use a Sigma 70-200mm mostly, by far the majority are taken in the 70-100mm range.
