Which Sony ISO RatingS Are Correct?

In the course of my tests with the FX3 and comparing it with the FX6 and FX9 I discovered a strange anomaly with the FX3 and A7SIII ISO ratings when compared to the FX6 and FX9. 


The FX3’s default picture profile is PP11 and S-Cinetone. If you have an FX6 or FX9 these cameras also default to S-Cinetone in SDR mode. In the FX6 and FX9 the base ISO for S-Cinetone is 320 ISO. Therefore you would assume that if you also set the A7SIII or the FX3 to 320 ISO and expose all the cameras the same, same aperture, shutter etc that the exposures would match.

BUT THE EXPOSURES DON’T MATCH!!

FX6-Exposure_1.1.1-600x338 Which Sony ISO RatingS Are Correct?
The FX6 at 320 ISO, 1/50th shutter, S-Cinetone.

 

FX3-Exposure_1.2.1-600x338 Which Sony ISO RatingS Are Correct?
The FX3 with the same 320 ISO, 1/50th shutter and S-Cinetone. It’s clearly brighter.



The FX3 and the A7SIIII are just over 1 stop brighter than the FX6 and FX9 when all the exposure settings are matched. I tested all the cameras with the same lens to ensure this wasn’t a lens issue, but it isn’t the lens.

FX3-S-Cinetone-scopes-copy-1 Which Sony ISO RatingS Are Correct?
FX3 S-Cinetone is brighter compared to the FX6/FX9 and over exposed according to my light meter by just over 1 stop. The white of the white card should be at approx 83% and my skin tones are well into the highlight roll off and looking flat as a result.

 

FX6-s-cinetone-scopes-copy Which Sony ISO RatingS Are Correct?
The FX6’s exposure much more closely matches my light meter and is only a fraction of a stop under with the white card just touching the 83% exposure I would normally expect with S-Cinetone.

Here’s the FX3 again, the whites are much, much too bright when exposed against my light meter, even the middle grey is over 60%. The MM+0.7 indication means the camera thinks it is over exposed.

 

Screenshot-2021-02-26-at-13.16.49-copy Which Sony ISO RatingS Are Correct?
And the FX6 with exactly the same settings and the same lens matches my light meter very closely, white is around 83% and middle grey around 45%, as I would expect. Something odd is going on here, it’s not just my light meter it’s something else as the cameras should at least match, even if they don’t agree with the light meter.



I then went on to test other gamma/picture profile settings and I found a just over 1 stop difference between the FX3 and my FX6/FX9 in any similar combination EXCEPT S-LOG3!

Screenshot-2021-02-26-at-13.14.18 Which Sony ISO RatingS Are Correct?
The FX3 shooting S-Log3 now it matches my light meter very closely and the exposure is add I would expect.

 

Screenshot-2021-02-26-at-13.14.41 Which Sony ISO RatingS Are Correct?
This is the FX6 set exactly the same as the FX3 shooting S-Log3. Now they both match and now the both provide the same exposure and closely match my light meter.



When using Picture Profile 2 on the FX3 which is uses Sony’s “Still” gamma and then using the “Still” Profile on the FX6 there is a difference of around 1 stop. If I set the FX3 to PP3 (ITU-709) and the FX6 to ITU-709 then the difference is again around 1 stop, in every case the FX3 is brighter except when you select S-Log3 where the FX3 and the FX6/FX9 match almost perfectly!

I find this very strange. They should not be different. My light meter suggests to me that the FX6/FX9 are correct.

Comparing to my light meter I believe the FX6/FX9 ratings to be correct and the FX3 to be between 1 and 1.3 stops brighter than it should be when using gammas that are not S-Log3. What I really don’t understand is why the FX3/A7SIII match the FX6/FX9 when using S-Log3 but do not match when using the other profiles, normally I would expect to see a consistent offset. This further makes leads me to be sure this is not a problem with my light meter, but something else.

I would love to hear from anyone else that’s able to take a look at the ISO ratings of the A7SIII and compare it with an FX6 or FX9.

The bottom line is – DON’T EXPECT TO PUT THE SAME EXPOSURE SETTINGS INTO BOTH AN FX3 AND AN FX6/FX9 AND GET THE SAME RESULTS, because you won’t, unless you are using S-Log3, then they match. 

Also in the clip metadata I found that 0dB for S-Cinetone is 100 ISO, and whether this is a coincidence or not, if I set the FX3 to 100 ISO and the FX6 to 320 ISO and then match shutter speed and aperture then the exposures are very close.

This one has left me confused!!!!

What do I think of the new FX3?

Screenshot-2021-02-24-at-09.28.59-448x500 What do I think of the new FX3?
Sony’s new ILME FX3

What do I think about the new Sony FX3. It’s certainly an interesting camera because it seems to be a bit confused about what it is.
It’s isn’t a mirrorless stills camera like the A7SIII, but it’s very, very like the A7SIII.
It isn’t a cut down FX6 or FX9, it’s very different to them.


So what is it and who is it for? Personally I see the FX3 as a great B camera option to pair with an FX6 or FX9. The FX3’s flat top and additional 1/4″ mounting points on the top and sides will making rigging it in more unusual situations much easier. It’s a camera I would use to rig in cars like a giant Go-Pro, perfect for any Top Gear or motoring shoots. It’s a camera I would use on a gimbal, it’s a camera you could sling from a drone. 

In most cases it would not replace any camera I currently have, but instead compliment it. It could be a good option for FX9 owners in particular as it would give them 4K 120fps as well as a second camera when needed.

The FX3 is not much more than an A7SIII in a different housing, with the EVF removed, new mounting points added and an removable handle with XLR connectors. There are some changes to some of the button positions and these make it easier to use when shooting video providing direct access to ISO,  IRIS and White Balance. The flat top makes it easier to mount in different ways and the built in 1/4″ mounting threads make it easier to mount accessories such as monitors. 

Really the FX3 is an alternative version of the A7SIII biased more towards video than photos. It doesn’t replace the A7S, just gives potential owners the ability to choose between the two different form factors depending on individual preferences.

For more information why not watch this recording of my Facebook live stream on the FX3.


Checking SD Cards Before First Use.

sd-card-copy Checking SD Cards Before First Use.With the new FX6 making use of SD cards to record higher bit rate codecs the number of gigabytes of SD card media that many user will will be getting through is going to be pretty high. The more gigabytes of memory that you use, the more the chance of coming across a duff memory cell somewhere on your media.

Normally solid state media will avoid using any defective memory areas. As a card ages and is used more, more cells will become defective and the card will identify these and it should avoid them next time. This is all normal, until eventually the memory cell failure rate gets too high and the card becomes unusable – typically after hundreds or even thousands of cycles.

However – the card needs to discover where any less than perfect  memory cells are and there is a chance that some of the these duff cells could remain undiscovered in a card that’s never been completely filled before. I very much doubt that every SD card sold is tested to its full capacity, the vast volume of cards made and time involved makes this unlikely.

For this reason I recommend that you consider testing any new SD cards using software such as H2Testw for windows machines or SDSpeed for Mac’s. However be warned to fully test a large card can take a very, very long time.

As an alternative you could simply place the card in the camera and record on it until its full. Use the highest frame rate and largest codec the card will support to fill the card as quickly as possible. I would break the recording up into a few chunks. Once the recording has finished check for corruption by playing the clips back using Catalyst Browse or your chosen edit software.

This may seem like a lot of extra work, but I think it’s worth it for piece of mind before you use your new media on an important job.

New addition to Sony’s Cinema Line On The Way

In some regards this is now already old news. I’m under NDA so there are limits as to what I can, or what I should write. Hopefully I won’t get into too much trouble if I point out that there are already a lot of rumours circulating right now that a new camera called the FX3 might be about to be launched. The official line is that there is going to be an announcement on the 23rd of February, just a week from now.  So why not just chill out for a one week as then you will be able to get the full facts about whatever it is that’s going to be added to the Cinema Line. 

Aliens Might Think The Earth Is Perpetually Dark!

If you were an alien on another planet and had access to nothing but all the latest camera demo or “film-maker” reels on YouTube or Vimeo you would quite possibly believe that much of planet Earth is in perpetual darkness.

All you see is clips shot at night or in blacked out studios. Often with very little dynamic range, often incredibly (excessively?) dark. I keep having to check that the brightness on my monitor is set correctly. Even daytime interiors always seem to be in rooms that are 90% dark with just a tiny, low contrast pool of daylight from a window filling one corner and even the light coming through the window is dim and dull. 

I recently viewed a clip that was supposed to show the benefits of raw that contained nothing but low dynamic range shots where 70% of each frame was nothing but black. Sadly there were no deep shadow details, just blackness, some very dark faces and where there were highlights they were clipped. It was impossible to tell anything about the format being used.

The default showreel or demo shot is now a very dark space with a 3/4 profile person, very dimly lit, low key, by a large soft source. Throw in a shiny car with some specular highlights or a few dim practical lights into the background for extra brownie points. 

Let me let you in to a little secret – it’s really, really easy to make black frames. Want a little pool of light – add a light to your mostly black frame. It’s really easy to shoot under exposed and then as a result not have any issues with dynamic range. It’s really easy to shoot a face so that it’s so dark you can barely see the persons eyes and then not have a problem with shiny skin.

But try shooting someone at a desk in a bright office and make that look really great. Try shooting a proper daytime living room scene and making that look flawless. A summer picnic on a beach with brilliant blue sky perhaps. These are all challenging to do very well for both the DoP and the camera.

We have these wonderful cameras with huge dynamic ranges that work really well in daylight too. But we seem to be losing the ability to shoot anything other than shots that have very low average brightness levels and low dynamic range. They depend on often coloured or tinted lighting to provide some interest in what would otherwise be a very, very boring images. Where are all the challenging shots in difficult lighting? Where are the bright, vibrant shots where we can see the dynamic range, resolution and natural colour palettes that separate a good camera from a great camera? 

Dark is getting very boring. 

Atomos Adds Raw Over SDI For The Ninja V via the AtomX.

I know this is something A LOT of people have been asking for. For a long time it has always seemed odd that only the Shogun 7 was capable of recording raw from the FX9 and then the FX6 while the the little Ninja V could record almost exactly the same raw form the A7SIII.

Well the engineers at Atomos have finally figured out how to pass raw via the AtomX SDI adapter to the Ninja V. The big benefit of course being the compact size of the Ninja V.

There are a couple of ways of getting the kit you need to do this.

If you already have a Ninja V (they are GREAT little monitor recorders, I’ve taken mine all over the world, from the arctic to Arabian deserts) you simply need to buy an AtomX SDI adapter and once you have that buy a raw licence from the Atomos website for $99.00.

If you don’t have the Ninja V then you can buy a bundle called the “Pro Kit” that includes everything you need including a Ninja V with the raw licence pre-installed, The AtomX SDI adapter, a D-Tap power adapter cable, a mains power supply and a sun hood. The cost of this kit will be around $950 USD or £850 GBP + tax, which is a great price.

On top of that you will need to buy suitable fast SSD’s.

Like the Shogun 7 the Ninja V can’t record the 16 bit raw from the FX6 or FX9 directly, so Atomos take the 16 bit linear raw and convert it using a visually lossless process to 12 bit log raw. 12 bit log raw is a really nice raw format and the ProResRaw codec helps keep the files sizes nice and manageable.

This is a really great solution for recording raw from the FX6 and FX9. Plus if you already have an A7SIII you can use the Ninja V to record via HDMI from that too.

Here’s the press release from Atomos:

Accsoon Cineeye 2S Wireless Video Link with Streaming Function

So there are now quite a lot of these devices appearing on the market. I have a Hollyland Mars 400 kit and it works really well. But this one caught my eye because it includes the ability to stream to platforms such as YouTube using RTMP.
In these days of remote production being able to stream the cameras output to a remote client or producer could prove very useful.

I haven’t seen one in person and I don’t know the company, so no idea if it’s actually any good. But certainly on paper it’s really interesting.

FX6 Guide to Cine EI – Update To Include StRange PlayBack EI Levels.

I’ve added some updates to my guide to using the Cine EI Mode in the FX6 (towards the bottom) to cover the strange playback behavior where the EI levels are reversed.  This can result in some very misleading brightness levels during playback that might make you think you exposed incorrectly.

Xperia Pro – Is this the phone all video professionals should Own?

Screenshot-2021-01-27-at-17.13.22-537x500 Xperia Pro - Is this the phone all video professionals should Own?
The Xperia Pro has an HDMI input and can be used as a 4K HDR monitor.

 

A dramatic headline perhaps, but once I start to look at what the Xperia Pro can do, I can’t help but say – I want one! The Xperia Pro is so much more than just a phone for making calls or watching YouTube videos.

The Xperia Pro shares many features of Sony’s flagship Xperia 1 II and adds an HDMI input.

HDMI IN. Yes, that’s right – it has a 4K/HD HDMI input. So you can plug your camera into it and use it as an HDMI monitor, plus its HDR so you have a small pocket sized HDMI monitor. When I travel (travel – hopefully that will happen again) to remote locations I often don’t take a monitor because of the extra bulk. But being able to use a phone as a monitor from time to time would be such a help. It supports HDR and Rec2020 and has pinch to zoom if you need to enlarge the image to check focus etc.

Streaming from the HDMI input.

Install a streaming app on the phone and you can use it to stream the HDMI feed from any connected camera direct to your favorite platforms. No need to use clumsy tethering, just plug in the HDMI and start your favorite app.

5G millimeter wave. Because the phone features 5G millimeter wave connectivity, where available you will have access to extremely fast data transfer speeds for streaming or ftp transfers. The phone also includes a Network Visualiser App that allows you to find the best network connectivity so you can be sure of the best possible connection wherever you are.

3x High Quality Cameras. The Xperia Pro has three 12mp cameras with Zeiss lenses that are the equivalent of 16mm f2.2, a particularly impressive 24mm f1.7 as well as a 70mm f2.4. The cameras have been co developed by engineers from the Alpha team and feature full manual control as well as raw stills. For video it can shoot at 4K HDR at 24, 30, 60 and 120fps with an optional wide screen 21:9 (2.370:1) aspect ratio mode that matches the 21:9 aspect ratio of the phone itself.

Screenshot-2021-01-27-at-17.14.51-600x369 Xperia Pro - Is this the phone all video professionals should Own?

But all of this goodness comes at a price. Currently its priced at $2499 USD which is a huge amount of money for a phone. The very similar  Xperia 1 II without the HDMI input can be found for less than half of that. But for someone that streams a lot, perhaps for TV news applications there is a lot to like. You could use the phone as your camera or use the phone to stream from a better camera, easily and simply. With 5G you can use it to upload finished packages quickly and easily. The cost of any high end phone plus an HDR 4K monitor would be close to that of the Xperia Pro, so while it is a lot of money it isn’t perhaps as outrageous as it first seems.
