K-5 IIs moire: found!

Finally found a situation that provokes moire..


shot with Tamron 17-50 f2.8, f/4.5, 1/100, ISO400 at 21mm

You can clearly see the moire at the photo wall behind the subjects.. also, am not sure but it seems the lens back-focuses on my camera

Or was the focus point straight on the background?
Definitely provoked it there.

The moire doesn't bother me, but the wide angle distortion sure does.

Ah nope, used center-point AF at the middle guy's stomach.. looked at other photos and it definitely back-focuses... but strangely enough, it only happens when there's a wall in the background (that is around a foot or closer to the subject).

lol no moire on the shirts (maybe because they're OOF ), just the wall. Haven't tried yet, just opened it in Photoshop's raw converter.
...and my C1 6 at home does not support K-5 IIs

Didn't correct the distortion yet, but will do before submitting to local publishers...

That would bother me, the IIs is definitely not for me. It's nice to see the Nyquist–Shannon theorem at work in practice, though. Thanks for sharing!

Whoa, looks like we got a kabayan here hey man. Ramon's a nice guy, really. He jokes around even off-cam. I forgot to record an interview though. Too busy taking pictures =))

The media in our city is somewhat more tolerant of distortion but more meticulous in color accuracy and sharpness. If worse moire comes out of my K-5 IIs I'm going to have to create a better, faster PP workflow or just change my shooting style altogether

Well yes... good thing I shot in RAW. However, considering the number of shots I took at this photowall... I'm afraid I'd have to go home very late tonight. Plenty to PP...

Yes sir, kababayan here (: I'm glad there's a pentaxian over there in the mother land doing this kind of work. I'm actually shocked at first, Am like damn, Filipino pentaxian in the Philippines! that's a very rare sight!

Kudos bro (:

Nice moire, but now for the important question... What planet are those women from and how long does it take to get there?
