Well, no.

It simply doesn't display the cyan-magenta shift of your 24mm. And this is a 100% crop, not at web sizes like your example. Get the idea?
Groooooooan.... OK, I'll bite... mostly to clarify what's going on for the sake of others reading this thread.
You yourself said that CA manifests at the boundaries of light and dark and that's what is visible in the 24mm shot I posted. I'll add that it's probably going to show up more towards the edges of a shot taken with a wider angle lens and the point is still valid despite the crop factor. Just like the shot I posted. As I said this is a worst case thing.
Are you getting the idea now?
You also stated that it's just a matter of ticking a box to remove and that's true with this sort of CA...
100% crop from the image
as processed and saved...
So what's the problem?
Like I said,
there is no significant CA in the shot.
Final image when processed and saved on my pc...
And based on a 800 wide image posted on line you then quesation the sharpening? It's not oversharpened.
It's been sharpened in the CS5 raw processor and it looks good to me on my screen. I could even add some more sharpening by additionally running it through Smart Sharpen at 70% radious .3. These images aren't specifically processed or sharpened for the web, I never bother, I just squirt them through Photobucket and they will be mangled a bit by the process but even so you should be able to see that there is no oversharpening even with the additional Smart Sharpen on top of the raw processing.
Centre at 100%...
Top left at 100%...
Top right at 100%...
There just isn't an issue.
I posted the original image as an example shot from a (newly bought old) lens and I accept that work was done to produce the final image but producing the final image from the raw took less than 2 minutes and consisted of loading my defaults, fiddling with the exposure and fill light, contrast, saturation and vibrance and crop which may sound a lot but in reality it isn't and took about two minutes max, hardly heroic measures and no more than I'd do for any other shot.
I'm happy with the performance of the lens. It's pretty much in line with what I'd expect to see from any of my wider lenses especially in a shot like that which is a severe test even with the crop.
Even on my FF camera the lens performs well
and on FF there's still no significan CA.
I'm just amazed that you can make so many judgements based on a 800 wide image posted on a forum
IMVHO it's a decent lens with no significant issue
