Which is something that I and plenty of other people find obscene. No company should have a say with what I do on something that I have bought. Or how I want to upgrade my computer that is. https://www.bleepingcomputer.com/news/government/eu-prepares-right-to-repair-legislation-to-fight-short-product-lifespans/ https://www.bleepingcomputer.com/news/government/us-states-considering-legislation-to-introduce-right-to-repair-for-electronics/ https://www.bleepingcomputer.com/news/government/ftc-warranty-void-if-removed-stickers-are-illegal/ "Limiting repair options illegal under 1975 US law The FTC says that such practices are illegal under the Magnuson-Moss Warranty Act, a law that governs consumer product warranties, and which states that no company can put restrictions on the way users choose to repair their products. The law says that companies can't force users to use only certain types of (astronomically-priced) replacement parts, take produces for repair jobs only at certain repair shops, or can't plaster anti-tampering stickers on products to prevent users from repairing their own products."

As far as potential damage goes, it wouldn't matter whether it occurred while taking the computer apart or having it drop on the floor by accident. Same thing with a laptop. Many things other a broken screen can get damaged, and thats why there are tests that all these companies perform to identify damaged parts. So denying parts because of this makes no sense engineering wise.

Not only that, but they wouldn't even allow selling the parts for anyone else to fix. And if by making a YT video to recover their losses also brings to light the lack of proper support from Apple and hopefully forcing a change that would benefit the professionals, is perfectly understandable.

maybe

wow, that is indeed a problem. If a battery lasts for ~half an hour then even if shooting 15-20min clips that would mean a clip per battery to be on the safe side.

It is highly unlikely for the A7sIII to have any form of 10bit. At least internal. They would need to use a different wrapper other than the XAVC-S for that. Also it would undercut the FS5ii. XAVC-S can support 4K 60p though so I am confident we will see that. If they manage to get the fast readout times of their stacked CMOS sensor with video and offer near global shutter performance, coupled with 4K 60p, excellent low light, battery performance and very good AF that would still be an excellent camera and a worthy update from the A7sII. If the use the 24MP sensor of A9 then that would make it even better since hybrid shooters will appreciate the extra resolution for photos. While I would like 10bit as much as any other member of this forum, Sony does not have that much competition yet in order to potentially sacrifice sales of their professional line. Someone could argue that GH5/s is a good alternative but once you have the 60p with near global shutter and very good AF with a 24mp FF sensor it would distance itself by quite a bit. And I really doubt Nikon/Canon would come up with a FF mirrorless camera and internal 10bit anytime soon. That brings me back to the FS5II. A reason that Sony only updated a firmware might be because the competition is still slow. All C200/EVA1/FS5II have some form of RAW, 4K 60p, low light that is not that different. C200 offers a vastly better AF than the other two, EVA1 has the highest resolution sensor and FS5II has the electronic ND. Maybe color was the only thing Sony needed to address in order to match the competition...

Com'on Jon, use the Vehydra 12mm at f/5.6 and and anything that you can follow will be in focus

That delay in the display though...

Yep, also it depends on the type of shot. For relatively static shots you can get away with almost any shutter angle. Faster camera movements can become quite distracting and then testing few shutter angles would be optimal. Sometimes you want the extra smoothness/dreamy look, others you want movement to be sharp. No reason to stick to one shutter angle unless you don't enjoy experimenting.

For dual ISO you need separate analog circuits on the sensor. So hardware. The software just switches between these analog circuits at a specific ISO value. There is no strictly software dual ISO because that means applying gain, which would always amplify the noise floor as well.

Even though this specific situation is most probably going to be resolved in few months, it does reflect the flippancy with which Apple targets professionals the last years. I remember in my good old thinkpad days, anything that happened to my computer would be fixed next day on-site for free. Dell offers similar support.

The only way for a bump in DR to happen is to have a dual ISO implementation. That is a separate analog circuit for higher ISOs.

Yep unfortunately that's my guess as well. The ZcamE2 is meant for internal use, almost studio like. I can see how in that situation you have control of the light so higher ISOs are not that important, but at the same time because you have lights the dynamic range is also not that important. Thus if it ends up being true, I would see it more as cost cutting measure/spec bragging than something that would be more useful for videographers.

That makes sense. With dual ISO sensors they way the circuitry is tuned, usually you sacrifice the performance at lower ISOs in order to gain performance in the higher ISOs.

They probably need to do extensive testing & fine tune the preprocessing. There is still half a year till these are ready. With so much demand why risk it?

@sam first of all thanks for the very informative test. To me it seems that there are occasional "hiccups" where S8 and 1DC in lesser degree miss a step and skip to the next. So motion cadence (defined as the quality of motion?) is affected not only by shutter speed, shutter type & codec but also consistency of frame times. But there is no need to get defensive... fuzzynormal just stated his opinion, and to a large extent I agree with him since shutter speed to me affects the motion cadence the most. Even in your test at the beginning I could not tell the difference, and only when I slowed down to 1/4 the speed I could point to the delays. I might not be the most sensitive person to the motion cadence, but I doubt the majority of people would notice either especially when not comparing it with other cameras. For example has anyone complained about the motion cadence of 1DC ? Now the tessive shutter article that you posted is also very interesting. I didn't know about it, but that at least partly explains our subjective opinion that a slower shutter than 180 can help with the motion blur. Let's keep this place on the positive side, and I welcome any tests that you do! Cheers

Yep I too find that using a slower than 180 shutter works great. 1/40 for 24p looks fine for fast motion.

Has anyone checked these? I am considering it since it is very cheap at $350 and has the feature I need most, a TOP HANDLE! Not only that but it supports the clear zoom for Sony. Panasonic cameras are supported as well. They have two versions the M and the Pro for different weights but the M supports up to 1.3Kgr which is more than enough for most mirrorless cameras. Unfortunately I just found about about their recent indiegogo in which you could even get one for $200! It looks like it will be available from May. Here is more info: https://www.indiegogo.com/projects/kylin-m-3-axis-stabilizer-for-lightweight-cameras#/

Here is a funny take:

I believe the USB-C can only be used to charge the LP-E6 while the camera is powered off. When the camera is powered on then the USB-C can only be used as an external storage and not power.

That is exactly what my answer was about. These are the main factors that change with sensor size and affect image quality. Of course there are million other things that affect image quality. If you need 15 stops of dynamic range you have to go use a larger sensor currently (because sensor technology is also very important), but again image quality is far more limited by the processing pipeline than the sensor size. For example the original pocket with its tiny sensor, offered far better image quality than the majority of consumer 1080p cameras with sensor sizes even 8 times larger. Also pixel resolution is not that important as most films you see in the cinema are in 2K and nobody complains about the resolution. Not to mention all the large sensor cinema cameras that are used professionally and have less dynamic range than the tiny sensor from the pocket. Another example is the GH5s that many argue it offers better or at least similar quality to the A7sII but with a sensor ~4 times smaller. But let's not deviate from your original question: No.

There are two main ways sensor size can affect the maximum resolution: 1) The ability of a lens to resolve finer details than the distance between two neighboring pixels. --> There are plenty of lenses that support far higher resolution than 4K so that's not a limit 2) The ability of pixels to collect enough light. --> Current m43 sensors with large pixels offer ~13stops of dynamic range and excellent color information. So in short, in that article just suggesting that for 4K someone needs a LF sensor, is plain wrong and marketing bulshit. In general systems are far more limited by their processing pipeline than optics/sensor performance, and that's why offering RAW is such a big deal.

Yeah, even his conclusions are strange to say the least: "The only way the Blackmagic Design Pocket Camera 4K can beat the GH5 is in terms of sheer image quality – dynamic range and color science." But really, aren't all the comparisons of cameras that haven't been even released rushed?

I am not that sure that the ZCam E2 needs much to get operational. If this camera is used for the stuff it is intended aka tethered shooting, then you only need a power source. Battery or cable. Also don't forget that you can use your phone through the USB-C as a monitor, no dongle necessary.

Here is another rundown of the specs: https://wolfcrow.com/blog/best-4k-60-fps-cinema-camera-under-2500-a-fun-comparison-between-the-blackmagic-design-pocket-camera-4k-panasonic-gh5-and-gh5s-and-the-z-cam-e2/ Comparing footage will be a bit more interesting, but my guess is that as with any camera nowadays, it will come down to our personal opinion ...
