DA*200 on the K5. I was about 50-75 yards (meters) away when I shot this. The first shot isn't anything special, just thought it was cool to frame the fisherman between the two palm trees.

Then, as I was zoomed in and sharpening the picture, I noticed that you could actually make out the fishing line in the shot. Here's a 100% crop:

I'm impressed! So, is this the lens, the camera, or both?

Both!

A bad lens wouldn't resolve the detail.
A low resolution sensor or camera shake would mask/blur the detail.

Enjoy your K-5!

Both, but the PF in that crop is all lens (dont worry about it though, that's very mild, all lenses do it to some degree)

Remind me what "PF" means?

The requirements for creating a good enough photo are like links in a chain.

The strength of a chain is determined by the weakest link.

Therefore your seeing the fishing line means that the lens was good enough, the focus was good enough, the display was good enough, the sensor was good enough, the exposure was good enough, the air was clear enough, the lens was clean enough, the camera was steady enough,....

There is a loooonnnnnggg list of things that must be brought into balance to optimize photography.

This also applies to the subjective, artistic aspects of a photo.

Oh yeah, the DA*200 can produce some amazing PF. It's worth it though, for the otherwise outstanding images the lens can produce. Also not that hard to avoid, as it's pretty predictable when you're going to see it (like bright white objects against a dark background).

Oh, and actually, the camera can play a bit into the PF as well. My 16-50 had terrible PF on my K10, but on my K20 in the same conditions, didn't show it. OTOH, the DA*200 didn't show PF on the K10 as quickly as it did on the K20D. Something about the microlenses on the pixels or some such. Still, it's largely on the lens.

Lens. I think any recent camera with same lens would have resolved rope.
