I have been using dummy batteries for my two Zf's and Z8. The Zf's do show camera overheating warnings but on the Z8 I only get Hot Card at the same time your are reporting. I believe that the Hot Card warning is for not touching the card after you try to remove it when it is hot. Reminds me of the lawsuit against McDonald's for the spilled hot coffee. So every company has giving this type of warning. California warns about everything. That is why I do not plan to visit the state in the near future, LOL. I am interested with the new Type C CFexpress Cards though and by being faster they will generally put out more heat. My Z6II and Z7II did overheat when I used those type of B CFexpress cards. I might of got a lucky Diamond in the rough with the Z8. I have been video recording at H 265 10 bit for at least 30 minutes to an hour and a half without any problems except for the Hot Card Warning. That also includes the SD card too! I have not experienced anything on my Z9 on video because I tend to shoot Pics instead of video. Bought two of those snap on lens hood that you recommended in one of your latest videos to go with my small Z compact lenses. Love them! Cheers!
Question I have 1700mb/s cf in primary which I’ve assigned RAW image to, and 250mb/s SD card slot assigned to low res jpeg. But I’m not getting the high frame rate I need as a wildlife photographer, is the sd card choking the speed? I only use jpeg to quickly screen my photos before editing individual RAW files.
I am confused. I got my Z8 last week, I have a cfx card, planning to buy a sd card for back up. So even if the primary card slot with CFX can be written really fast, the second slot with SD will choke up the camera? Do the two cards have to be written simultaneously? I thought I can fill the primary card as fast as possible, then the camera can work behind the scene to copy the images to the second card slowly. Say if the camera detected that the primary card has more images than the second card, it'll keep copying? why it can't do that? Thanks!
Because backup means that you get all files on the second card even if the first card fails catastrophically. The way you describe of using the 1st card as a buffer somewhat defeats the purpose. But it could be an option though. I’d also like have an option for the backup card to skip some frames in 20fps bursts to maintain higher sustained framerate overall.
I don't understand what you mean. First write the images to the first card, and copy them onto the second card (automatically)at a slower speed is very useful to me. I discovered that Nikon offered manual copy option, but I haven't got my SD card yet, thus haven't tried that out. I am hoping if influencers shout out on this, Nikon may eventually give the automatic copying function. @@pooofykittens
It seems you need a Z 9 rather than a Z 8. (See my comment about cards under this video, by the way.) I bought a Z 8 and it's the first digital camera that puts a smile on my face. My Delkin CFexpress cards are robust enough to not need a "backup" card, however I always shoot JPEG to the second slot with a very fast SD-UHS-II card. These SD-UHS-II cards are too expensive and too slow compared to CFexpress Type B, but I don't need a Z 9. If I have to shoot things that are so important that I cannot loose any shot/take, then I would record to an external device next to the card in the Z 8. Or rent a Z 9.
@@pooofykittens - the question is what risk we try to mitigate with the second card slot c.q. card. With high-end cards, card failure has become more or less theoretical. I don't mitigate for that. If I had to record "backup" (a simple variant of RAID 1 - AKA mirrored) then I would still have the risk of camera/controller loss. In enterprise IT, data corruption by a faulty I/O controller is not theoretical. Rare, yes. Like "spontaneous bit flips" - also rare, but shift happens. If you need to mitigate camera loss, then you eed a second camera, not card slot. And, e.g. as wedding photographer, you would use two cameras and shoot with them alternatively, because you need a shot or take with the other lens, time and again. In my case, I use the slow second slot to get SOOC JPEGs next to raw. This uses different circuitry in the camera, but the question is if the two slots are on the same I/O controller and firmware therein. From a risk mitigation point of view. Find your own risk analysis that is relevant to your use cases. You may come to a different position than you have today. Do you "need" 20fps raw at full resolution because the camera has it, or because you really need it? If you never go into Photoshop in post, if you only adjust a bit of exposure, WB, tint, in Adobe Camera Raw (the Develop tab in Lightroom Classic) then you might as well shoot SOOC JPEG. That's not a trolling insult. It's what camera collector Ken Rockwell in his camera/lens review website says he relies on for his commercial photography.
@@jpdj2715 what you are saying makes sense. For me I made a decision - I need occasional high FPS for animal action, and long bursts without slowdown will be appreciated. In most cases I use single shot mode anyway. RAW is the only option due to its flexibility and shadow / highlight data retention. It’s possible to do a heavy crop and processing and recover details that in-camera JPEG would never be able to show. I don’t have issues with storage or processing power and it’s not worth it for me to compromise quality of 10k+ camera setup. Ken Rockwell is the exact type of photographer who needs OOC JPEG, most of his opinions aren’t useful to me. I’ve never seen a good photograph out of him. He should stick to iPhones and sell his gear to someone good. And a lot of professional photographers aren’t capable of producing the same high quality output that very advanced hobbyists can. So being a professional doesn’t equal competent or talented. I’ll have to admit though that the best photographers I know are professionals, albeit the absolute minority, and are talented and famous. The only thing I want to cover with second card is NAND memory failure or any hardware failure of a CFexpress card. I understand that it’s unlikely to happen when the card is new, but it’s worth the cost for me. I already had a good quality SSD fail suddenly after less than 1 year of use. I’m trying to find out what type of memory cells is Delkin using in their Black and Power lines. Or at least a good datasheet that shows max write cycles (endurance). Because there’s no way that Power has the same endurance and reliability as Black while having significantly lower price per GB. The fact that these values aren’t easily available unlike for consumer SSDs makes me quite sceptical.

Great video and thank you. I'm after the Z8 as well and getting a heads up on cards.
Glad to help.

Thanks for adding your experience, Randall. Glad the hoods worked. I have a new card test coming for the Zf.

Yes. Those scenarios are covered in the video.
