A K5IIs pic and Moire

David&karen · 11-06-2012, 06:43 PM

OK, here is the only Moire to show it's head today: The power lines. The pic is from the Tammy 70-200 f2.8 at f6.3(I think the best sharpness at that point w/o diffraction). The microwave tower is a 100% crop, the power line also a 100% crop.

Unless I'm missing something, I'm not seeing any moire. I think you're just seeing the limitations of this sensor and its resolution! (could be wrong though)

Looks like heat distortion to me.

Just to be different

, I'm seeing a touch of chromatic aberration on the power-lines, specifically some green fringing, not moire.

I agree. I don't think there is any moire in the image, and at that level of magnification it would be irrelevant as you have other IQ issues that are degrading.

I'm just seeing some cool resolution

I think it could be either, the image does the moire color change thing on my monitor, but heat distortion could be it also...go figure, but on the K5 classic it does not have the colors. BUT, it is irrelevant to any pic I can imagine, just an observation. BTW, these were the in camera JPG's , I had meant to use the raw's but selected the wrong pic. YMMV,

Oops, I just looked at the K5 classic pics and when sharpened they look identical, so heat issue I guess, sorry to mislead....

No problem!

Just be aware, moire can be misleading when you are trying to look for it.

Yep, this is aliasing, not moiré.
