Re: New shots from the XF100

Thanks.

The XF100's LCD monitor is a little bit to green, so I adjust WB only with kelvin (from experience by time of day, it depends on whether the sun is shining, etc).

Color corrections are...

Re: New shots from the XF100

Thanks for your feedback, I'm quite happy with the XF100. Perhaps a better viewfinder and a little more zoom would be nice.

Re: XF300 Pattern issue with video

What level of coring, gain and denoiser did you used?

Try set denoiser to 0 (no denoiser), gain -3 or -6dB and coring set to +3.

No optical ND filter can make slow and smooth change of the exposure (during turning on).

Re: XF-100 - My impressions after a 100 hours with the camera plus some test videos

This is very simple (but my english isn't very good .-) ).
The negative gain is an attenuation in the signal processor of the camera, does not affect the overexposure of the chip, it has impact on...

Re: XF-100 - My impressions after a 100 hours with the camera plus some test videos

Re: XF-100 - My impressions after a 100 hours with the camera plus some test videos

Changing the optical ND filter can be seen on the record, I know this from my XH-A1. So I think that XF100 has the electronic ND filter (changing is not seen, it is slow and smooth after switching ND...

Re: XF-100 - My impressions after a 100 hours with the camera plus some test videos

The ND filter isn't a negative gain. It is some control of the chip sensitivity. The only limitation is the lower range of the control against an optical filter (max is 1 / 16 vs 1/64 with the...

Re: XF100 - 422 vs 420 chroma key

Re: XF100 - 422 vs 420 chroma key

I don't have the xf300, but it has much more better lens and the three cmos chips, it gives true 422 color sampling. The lens of the XF100 is much worse and 422 colors are interpolated by deBayering.

Re: XF100 - 422 vs 420 chroma key

XF100 is not the king in chromakey, XF300 is much better. I did this test for more information about "debayering" from CMOS with 2mil pixels. I want know if the 422 colors are only "upscalled" from...
