News S1Rii - Read all about it!

An interesting burst mode comparison/test from Richard:

The prores raw format, that the S1R records internally has a Bitrate of about 1.5 Gbps, so the camera should be capable of high writing speeds. Theoretically it should be possible to use this capabilities in burst mode. The RAW files of the S1RII are between 50 and 65 MB, jpeg about 20 MB. That means between 15 and 20 fps should be possible with constant writing to the CF Express card. Or did I get something wrong?

1.5Gbps (gigabits per second) is 187.5MB/s (megabytes per second) so if the RAWs were about 60MB each it'd take 22.4 seconds to write 70 of them at that rate, which is in line with Richard's results. Since the card is labelled as being capable of a sustained write of 850MB/s it looks like the limitation is in the camera.
 
I didn’t watch the videos, but just looked at the sample gallery from dpreview and I must say that the 20-60 performed quite good with high resolution. At least while watching on my iPad.

Thanks for clarifying.

Ironically, I did a second mistake. I also confused ProRes 422 HQ for ProRes RAW HQ. The Bitrate for ProRes RAW HQ in the S1RII goes up to 4.2 Gbps(according to cined.com) what would be about 560 MB/s. So it should take less than 10 seconds for writing 70 RAW files or it should be possible to instantly writing up to 9-10 fps on the card. Maybe more. It still looks like software limitation, that could possibly get improved.

I downloaded the dpreview raws and have been lookig at them with FastRawViewer, where you can blow them up. There is a 20-60mm picture of a bus, a white and cyan colored bus, that is especially sharp. It looks like the 20-60 might work well with S1Rii. By the way, there are a couple of 'hi rez" photos in the dpreview photos, and they are both very poor, not sharp when blown up. I don't know if the issue is the camera or the lens or the operator.
 
As i said in my review, when shooting pre-burst, the time to write the buffer to card, no matter you use v90 SD or CFEB 4.0 card, no matter you choose RAW or JPG format are all almost the same. It suggest the bottleneck is at the processing pipeline.

However if you use a slow card like a v30 SD,, then your write time would go up dramatically!
 
@Richard Wong

Did you do the writing speed tests with only one card in a slot or was a second card in the other slot?

Has Panasonic seen your writing test? Maybe it is something they can fix in FW update like the bug Gerald Undone found in his first tests?

Even when you write to the CF card only? Let's say, you are using a fast CF 4.0 and a v30 SD, will write slower to CF only compared to fast CF 4.0 and V90 SD to CF only?

if you put a slow card to SD slot but not write to it, then it wouldn't affect the speed.
Hope that's what you are asking, if not I'll try to answer again

Nope i haven't send to them. But I don't see anything really unusual so haven't ask them about it.

What's the bug Gerald undone found in his first tests? Sorry I have not watch his review.

I do not remember anymore. I am Sorry. I watched so many YT reviews on that day, that I need to check it again. He mentioned that I think in the first 3rd of his video.
 
I see. I have reported probably a dozen of bugs to Panasonic during this review. I went through 3 or 4 firmware updates and they have fixed all of the issues I reported.
But this is pretty normal when testing pre-release cameras.
Unfortunately, it means I had to repeat a lot of my tests many times as the earliest tests with bugs is meaningless and not even worth mentioning in my opinion
 
In the S1Rii I am very interested in the 14 stops of dynamic range and its behavior in terms of noise at high ISO. Because for me this is much more important than the rolling shutter or the speed of the camera in general.

For me, as a Nikon user for years, an alternative to this camera is the Nikon Z8, but reading people's opinions on the Nikon forums in Spanish (nikonistas.com), I think I am going to prefer the S1Rii because of opinions like this one (from Setnakht) about the Z8 that I copy and paste translated:

"A little down with first impressions:

Hello,
After completing my first two basketball games with the z8 combined with the 24-70 2.8 z and the 70-200 2.8 z, the truth is that I have mixed feelings. I come from a lumix s5 which I sold before having the z8 (before I had the z7ii, d4, d800, d810, d700, d3s...) and I was badly surprised by the noise in the photos. Starting from the basis that the matches were on fields with a dire light of course and that has a lot to do with it. The first match I shot at ISO 3200 2.8 1/1250 and the second at ISO 4000 2.8 1/1000. It is true that in this second match, despite seeing the exposure meter it told me that they were underexposed, I thought that when I raised the exposure the Lightroom would not be serious but I have already seen that no, that a lot of noise comes out. (...)

It is clear that for those ISOs the z6iii would be better for me but I also do birds and surfing and the 45mpx and the cropping is that for me it is everything. I will have to sacrifice one thing for another. Of course, for the next one I will use more ISO, for fear of not going above ISO 4000, the truth is that I have found a horrible noise when lifting".

I have seen many opinions like this on that forum. Here another one (from Longimanus777) in the same thread:


"I had the same feeling when purchasing the Z8, I wrote about it at the time when giving my first impressions in the general forum of the Z8, it came from the Z6II and it was and continues to be for me, traumatic in terms of noise.

There is no solution, this camera generates a lot of noise, in my opinion (I cannot compare because I have not had them simultaneously) much more than the D850.
The only thing I do is that even though I am at low ISO, I give the lightroom AI noise reduction and in the field I usually underexpose a little before overexposing.

I already said it, I wouldn't buy it again, if I hadn't rushed it, I would have the Z6III now.
Otherwise it is a very good camera, but the ISO issue is something that I usually take very high when photographing mammals".


These are opinions from Nikon users, not Sony, Canon or Fuji fanboys trying to bash Nikon.
I'm going to wait for opinions like these from users of the S1Rii to decide if I buy it, but I'm in no hurry for now. I certainly don't mind if the S1Rii has not a stacked sensor. For me is more important the DR and its behavior in low light.

Speaking of low light, this is the best video centric review of the S1Rii. It shows the performance in an informative and creative way what it is capable of offering in low light. Unbelievable!!!



These Media Division people make works of art. I recommend their video about the "cinematic look", called "The magic sauce" it is really excellent.

are you referring to my buffer test short video? It was CFExpress card only.

Thank you for clarification.

Theoretically it should be faster, because the camera is also capable of writing faster to CF express cards while recording video. Hopefully Panasonic will address this in an update.
