Moire & Insect Eyes ??

I am seriously concerned about Moire pattern problems when shooting macro of insects with a
Sony EX3. Since their eyes are comprised of hundreds of honeycomb-like facets, a serious moire pattern could ruin the shots.

If anyone has "first-hand", "expert" knowledge of any moire problems with the Sony EX3, I would greatly appreciate learning about it and to what extent it may be.

We are considering the purchase of a Sony EX3 for HD television production, and a great deal of our shooting is macro of insects. If Moire is a substantial problem, we should probably consider a different camera.

I would also be thankful to learn of any tests done on this camera.

Thanks.
 
All cameras, even film cameras, can have moire. Moire is a function of the frequency of the pattern compared to the density of the recording medium.

In general the EX1 and EX3 are much less likely to have moire than most cameras. Also, because they are full raster cameras most of the time zooming in or out a tad will get rid of what little moire is there by changing the frequency of the repetition of the pattern. Use a TrueHD monitor to see if you actually have moire. A monitor can show (or not show) moire if its a different resolution than the camera.

DSLRs (5Dmk2, 7D, etc) are well known for really horrible moire occurring over a broader range than the EX1/3.

Thank you Duke.

I have learned in the meantime that what you say is true and documented. For our kind of work, a Sony EX3 is a better choice for us.

I will make sure to get a decent monitor to check for moire too.

Thanks again.
