Hi,
i have tested the f35 with a 50mm master prime.
There appear a moire effect in horizontal fine lines of the picture.
I haven't seen this before on other HD cameras.

Neither have we. We have a full set of Master Primes and they have performed beautifully, if a little 'too' clean for my some tastes.

To see the moire effect in fine lines is again unusual to say the least. Were you shooting to SR and was the shot involving quick/rapid action?

We recorded on a SRW-1 4:2:2/25psf and no quick achtion.
We shot two talents on a bridge with wooden planks.
The effect appears on the cross over point between the plank and just in the foreground were we focused.
In another scene this effect appears in the cross beams of a rail which were far in the backgound but also focused.

I've never seen this effect on the F35 but I have seen it on other HD cameras say on a very fine weave jacket etc.

A little bird has told me its possible that the moire effect can be seen between fine detail that has a very strong contrast ratio, a dark window frame agaisnt burnt out glass, which seems to possibly describe your image, but no one else has seen this on the F35 as yet?

Can you rule out monitoring etc is it baked into the image on the SR tape and clearly viewable in Post, if yes then thats the answer.

Cheers
