BabsDoProd Posted August 14 Share Posted August 14 Hi, everybody, just a quick question. Does anybody know if the Fuji GFX100 II can exhibit moire when recording in external RAW video? I was watching a GFX100 II review video with some cinematic examples and moire popped up in a shot of an escalator and it threw me with how distracting it was. Does RAW mode fix this? If not, what's the prospects for someone making an AA filter like Mosaic Engineering did for Blackmagic cameras and the older Canon DSLRs?

eatstoomuchjam Posted August 14 Share Posted August 14 I haven't done much raw video with mine, but perhaps I can find something to shoot to confirm it with/without raw. Though in general, I'd say that I consider the movie modes on my GFX 100 II to be secondary to the still photo modes. If I needed a dedicated video camera, I'd get any number of other cameras for $7500 (for that kind of money, you could get a used FX6 and still have $2k left over for lenses). An add-on AA filter seems potentially problematic with a camera that has IBIS. Has that been done in the past? Quote Link to comment Share on other sites More sharing options...
BabsDoProd Posted August 14 Author Share Posted August 14 It's for the medium format aspect of it, that extra zest that the GFX series can provide that others can't. Of course the biggest problem I'm seeing is that we're not seeing medium format lenses being put on the GFX 100 II in particular, they keep throwing on cinema lenses that cover the sensor and it's just not the same. Also adding a GFX Mamiya 645/Pentax 67/etc. speed booster to give even more accurate medium format coverage would go a long way as well but there's just not too many cinematic examples at the moment with that combination. As for the AA filter, I'm not sure. I would think turning IBIS off would be the solution but if that is a problem for the AA filter manufacturers then I guess it's a moot point unless Fuji makes a version with one installed. They could definitely do it if they did do a cinema version like the Old Fast Glass Custom 65 camera. Quote Link to comment Share on other sites More sharing options...
eatstoomuchjam Posted August 15 Share Posted August 15 I'll repeat - if you want a dedicated video camera, the GFX 100 II is IMO one of the worst values you will find. If your goal is to have one of the best (arguably the best) still cameras on the market and have a lot better video than the original GFX 100, it's a great idea. Anyway, I'd suggest that you rent one and put it through its paces. You will likely find a number of concerns beyond moire. Quote Link to comment Share on other sites More sharing options...

They could definitely do it if they did do a cinema version like the Old Fast Glass Custom 65 camera. Rolling shutter is really going to be your enemy here. If you’re not shooting with much movement you might be able to deal with it. GFX 100ii is the first GFX to finally have decent video specs using the full sensor width but readout speeds are still just too slow. You’ll have to stay in 4k mode to see the most usable results. “In 14-bit mode, the sensor takes around 164ms to read its full 102 million pixels, so it's not plausible that it's using all its pixels to produce most of this footage, even if you assume a drop to 12-bit sampling for video. The 8K modes are the ones that appear to be sampling every pixel (seemingly from a fractionallyless than 8K region, and upscaling) and these have the worst rolling shutter despite using the smallest crops of the sensor. So it's reasonable to assume the other modes are pixel-binning or line-skipping to some extent.” As mentioned above, you should definitely rent one and play around to make sure you’re getting what you want. For me I was excited to pick one up and use all my Mamiya 645 lenses for doc work but the deeper I dive into the specs, the more I realized it’s just too soon. For the money I would get a used Sony A1 and a Ninja Ultra and have fun with that for a while. The “Medium Format Look” is an interesting combination of factors and a much heated debate surrounds it. I don’t want to get into here but suffice to say, you can achieve very similar if not the same results with the right combination of lenses on a nice full frame sensor like the Sony A1. There are alsoa lot of advantages to full frame sensors for video and I’m personally waiting for a couple more GFX iterations before making that deep investment for video.

eatstoomuchjam Posted August 16 Share Posted August 16 There are also some sensor smear issues visible at times with very bright stuff in the frame. For me, it's not very objectionable even when it is there, but I've noticed it in a few scenes. Ninpo33 1 Quote Link to comment Share on other sites More sharing options...
