This was shot on the first generation of red one sensor. It has very narrow dr according to the current standard. The sensor is tuned for skin tones. Can latest sensors do similar skin tones too?

why do you want to put on a lens adapter to make a lens softer on a very sharp camera? instead, you can put a sharp lens on a high quality 1080p cinema camera?

fantastic results, actually. you convinced me to buy the om-1. I will look for some deals during the Christmas season. thanks a lot for the help. you work on the train is also interesting.

by my experience, high dr is needed for situations like half shading and half sunlit face. for many common situations, 11-stop dr is good enough. for extreme cases, lighting can help to reduce dr, or moving the subjects to another venue. dr is important, but not that much weight like current thinking.

no. c100 mk ii dr is not as good as latest mirrorless.

most high end cameras with integrated battery grip have higher internal voltage than cameras with no battery grip, so faster af and some other features due to the higher internal voltage. add-on battery grip is better than no but not as good as integrated battery grip.

generally speaking, I think om1 video image quality is good enough for general usage. if carefully executed in acquisition and in post processing, the footage can be put on a theatre screen without much concern. as by my experience, a laptop screen with a viewing distance of 1 foot or a desktop 4k screen with a viewing distance of 2 feet, is more demanding than sitting in the middle of a commercial theatre watching the large screen.

uhd 50p 10 bit and fhd 50p 10 bit are the same to my eyes. no significant difference. if these are handheld shots, they are excellent. nobody will doubt that these shots are on tripod. uhd 25p 10 bit is almost the same as uhd 50p and fhd 50p, except that when cars move into the scene from the right to the center, when the cars enter, I can see minor jumpy feelings sometimes. the 50p modes have smooth car movements. om1 dr seems good. the sky and the clouds seem nice. thanks a lot for the testing footage. regards,

this is why I like to use c100 mk ii. I use it without the top handle xlr module at all. it has nd, good grip, angled evf, lcd, double recording. with some tuning, it can be sharp enough even by today's standard, as it is a 4k sensor. not much larger than a modern mirrorless if you put addons to it.

please delete this topic. it confuses readers. thanks.

sorry, you are right. I thought it was 1000 conversion. thanks for the correction.

the footage looks great even without any grading.

by my eyes, em5 720p 30p m-jpeg footage is not outstanding in details. maybe it is pixel binning or line skipping instead of oversampling like gh2.

they are 43 lenses, an adapter is needed.

Olympus should market this as one of the biggest features of em5, aside of ibis, yet it was buried for so long time, I just found it out.

I am trying to understand why motion jpeg codec is good on some old cameras. https://www.imaging-resource.com/PRODS/omd-em5/omd-em5VIDEO.HTM according to this article, em-5 720p 30p motion jpeg codec is 1/12 compression, 640x360 is 1/8 compression. for 720p 30p, uncompressed is 1280x720x30 about 30 MB/s, 1/12 compression is about 2.5 MB/s, about 2000 Mbps! for sd 30p, uncompressed is 640x360x30 about 10 MB/s, 1/8 compression is about 1.25 MB/s, about 1000 Mbps!

totally agree, it will balance my shg 35-100 f2, 14-35 f2, 7-14 f4 well.

personally, I think om1 probably is the Best Buy now, as om1 mk ii does not improve much, except that 200 frames buffer depth. I probably will couple om1 with my many mf lenses, in 1080p 10-bit all-i 60p 160 mbps mode. video quality seems fine to my eyes.

true. I am aiming em-1x once it reaches to around $500. maybe another 2 years. I have a set of shg and hg lenses. so I have to use em1 or om1 series for these 43 lenses, af, balancing.

good to know em-10 iii is better for video. can you explain more? if om 10 has an ibis of 6.5 stops, probably I will go for it, as it is much cheaper than om 1.

i think om-1 c4k 80 mbps 10 bit h.265 24p is usable and gradable, as long as you don't do slow panning or tilting or flowing the camera around. considering it has more details than other modes, it probably is the most prefer mode, even though the codec is very small. if there are many movements, which one is better? FHD 10 bit all-I 160 mbps 60p or C4K 10 bit long gop 150 mbps 60p or UHD 10 bit long gop 150 mbps 60p Maybe a tough question?

Another example, go pro 12 records at 120 mbps 10 bit 5.3k 60p h.265 (not sure if it is h.264). the results seem fine. there is room for color grading too. so, om-1's 150 mbps 10 bit 4k 60p h.265 may be good for general use.

By my personal experience, AF100A is 8 bit avchd 24 mbps 1080p 60p, C100 mk2 is 8 bit avchd 28 mbps 1080p 60p. Both are fine for movements if recording in 60p. To my understanding, AVCHD is a flavor of mp4, which typically is long GOP. 4K is 4 times of 1080p, theoretically, 8 bit 100 mbps 4k 60p H.264 is acceptable to record movements. Considering H.265 has better iq than H.264 at the same bit rate, 150 mbps 10 bit 4k 60p H.265 long gop is fine. Unfortunately, OM-1 C4k 60p is not as detailed as C4K 30p. OM-1 has a stacked sensor, so its 4K 60p should be fine for such a fast-reading sensor. Why the 4k 60p is not as good on OM-1? On the other hand, if it is a static shot, C4K up to 30p at 80 mbps H.265 10 bit may be fine.

Apple ProRes https://www.apple.com/final-cut-pro/docs/Apple_ProRes.pdf see the table on page 20. OM-1 FHD All-I 160 mbps is about the same as FHD Prores 422 LT 200 mbps. OM-1 C4K Long-GOP 150 mbps is even much lower than 4K ProRes 422 Proxy 400 mbps.
