Scott, this was a fascinating test! I’m also struck by the difference between the Canon R5 and the Nikon Z8 and Z9! This shows the advantages of the stacked, BSI sensors on the Nikon Z8/Z9 compared to the sensor on the R5.
Well the reason is the resultant image file size. You're pushing 45 mb through the canon and 55mb on the nikon. So that 10mb extra through the pipelines is the reason.The sensors etc won't affect anything its just the size of the image file that has to be pushed across the camera to the card , etc.
@@WILDALASKA so, despite the larger file size on the Nikon Z8 and Z9, the throughput (frames per second) is still faster! That suggests faster processing, faster data bus, and/or buffer on the Nikons. Is that correct?
Very good review and comparison. It really showed why you need to get test results of different cards in the camera body you intend to use. Just like any card reader/writer, if the card is faster than the reader/writer, you won't see any gain. It would appear that the older R5 has a slower data bus so the camera itself has a slower sustained write speed. I tempted to try this test with my R5 and my memory card to see how many frames I get with the memory card I currently use.
Yes. I shuld have ran 30 sec burst vs 10, but even doing 10 seconds took forever. This video was a headache to make lol. But was interesting on results.
Thanks -- I was pleased to see you were using the NEW 150GB DB card - which alongside the 325GB and 650GB are the quickest currently available. DB also market a NEW POWER CFexpress™ Type B G4 Memory Cards -- the term G4 appears to be new, and according to Delkin offer sustained sequential write speeds exceeding 1490 MB/s (805 MB/s for 128GB - 512GB), guaranteeing that data is written swiftly and safely to the card. Whereas the original but updated Delkin BLACK line distinguishes itself from the rest of the market by offering minimum sustained sequential write speeds exceeding 1240 MB/s, guaranteeing that data is written swiftly and safely to the card -- lower than you quote BUT ok - I just use them. The NEW G4 version of the Power card appears to be even faster -- well we will see.
Glad you liked it. Im getting the speeds directly from the manufacturer. I think the Power is a little less from what I read vs black but more affordable. Their website on shows max write speed which alarms me if the don't state sustained or min speed. Their chart on compatible cameras leads me to believe the black is better as thy have the Z9 listed as black recommended. Blacks are expensive. So finding this exascend was amazing to me. That's why I tested the crap out of them :) Delkin is here on the Black and Power. www.delkindevices.com/cfexpress-type-b/ Exascend Essential is here exascend.com/product-category/card-storage/essential-cfe/
What I noticed with the 128GB Sony card in my R5 is that its performance improved after formatting it in camera. I had been either doing copy+delete on my computer or selecting ‘delete all’ in camera for about 2 years. I don’t know how much of that effect is the card vs camera, but it did give me more frames per burst :)
Hi, Thank you for the review. The most important factor for me is going to be the temperature of these cards. That will be the deciding factor going forward. Over the next couple of years these manufacturers are going to hit the cap of the Type B tech for read and write, and they will likely compete on price per GB basis, then it will come down to TEMPS. They are essentially SSD's in a Card and just like computer NVME M.2 Drives some of them overheat and throttle performance or worst of all have errors when they overheat. I shoot in the desert, in direct sunlight many times above 100 degrees. Sports, wildlife and the Z8 is already getting hot card and yellow and Red camera HOT warnings from regular shooting with NO video. I would really love to see well documented heat tests using heat guns on the cards while running in the camera's (on the part that sticks out of the end) and possibly another way outside of the camera's. Thanks!
Good info. As I'm in Alaska, heat issues outside don't really ever crop up in stills. In testing indoors in controlled environment, in stills, the cards didn't get hot. In high bit rate recording and in transfer of files off the card, they did get hot. Not much way around the heat of the card. Now the camera itself gets hot also during record, but the Z8 held up ok. I haven't seen a warning yet. My Canon R8 did a few times in the studio after 30 min or so. But expected as its a RP body.
Thank you so much for going through all that prep to present your findings. Out of curiosity, there's a "Sounds too good to be true" deal on these: Silicon Power 1TB CFexpress Type B Memory Card, Up to 1800MB/s Read, Min Sustained Write: 1500MB/s. Amazon has 1 TB for $199, and B&H has them for $164! Have you heard anything (Good or bad) about the SP 1TB cards?
Thanks for the great video !! I know the Delkin black is known to run cooler than many of the other brands , did you notice any difference in how hot they ran or did you get any hot card warning filling up that 1 TB card ? If not I’m guessing it’s a great buy 👍🏻
Are you considering switching to Nikon? Noticed you first got the Z9, said you would just adapt your Canon lenses, then got the 200-500 and now the Z8. The continuous shooting and no rolling shutter are quite nice, plus it seems like Nikon has better wildlife lenses. Are you slowly being converted :)
So I LOVE the sensor in the Z9. but I LOVE the ease of use of the AF system on Canon and refer the menus and button layout. Also the Z9 video is amazing. And in picked up the Z8 to test, but it is a great walkabout setup with the 400 4.5Z. Both manufacturers a re amazing. Im waiting to see how the R1 and r5MKII work out and what lenses Canon drops in next year or so. Ill be testing the 400 2.8 TC Z this summer. I may just shoot both for the next few years. My wallet and retirement savings may say otherwise though lol
Im coming from a Nikon z6 where I had used Sony 32 GB XQD cards (read: 440mbs and write: 400mbs) for many years and they were great cards with that camera. As the years went on I got more involved with video and got the z8. When shooting in N-Log , Prores 422 HQ 10 bit, 4k60fps I can only capture a maximum of 15 second clips at a time. I can record multiple clips, but only 15 seconds long. My question is, is this the camera compensating for buffering and knowing the card can only write for this long before is exceeds its limits? is there some type of video settings or recording limit I need to change? The card is completely empty on storage so I know it has more space than that. I plan to get an actual CF Express B card with higher speeds here soon to shoot RAW but it was nice knowing I had these cards and could potentially get some footage with them, but maybe not.
yes the speed of the card is slower than the transfer rate so your getting a buffer overrun at the 15 sec probably. grab a good Type B and you will be good.
I liked the video - great information in my book. I shoot the R5 - But set it up to download stills to my sd card and video to the cf express b slot - I started shooting CRAW - with my sd I get 92 frames before hitting the buffer and only about 55 in full raw - I've yet to hit the buffer in CRAW, I haven't the image quality to be any different, but maybe I'm skilled enough to notice? did you ever shoot craw with your R5?
Yes I shot cRAW at times when I had the R5. I stopped shooting cRAW when I found on DXO's website that the RAW version of the files would work better with the processing. But yes in cRAW on canon and High efficiency on the nikon they shoot forever. But to be able to shoot losses raw on both and still get 10-17 fps after the initial 4 seconds is very nice on these cameras with a FAST. card.
@@WILDALASKA - Interesting, I'll look at see if I can find that information as I use DXO as well for my noise reduction. thanks for the information. great information
Hello, if understood correctly better to not put any SD card in the second slot as back up right ? The ProGrade 512GB CFexpress 2.0 Gold in first slot is a good one ? thanks
I try to get the manufacturer speeds if I can. The internal R5 written varies from deep dives I have seen. I cant find anything about just writing raw file only. There is this though "The actual R5 in-camera write speed is approximately 518 MB/s when shooting in RAW + JPEG L." which should be a bit more taxing pushing both. I would assume the RAW only would be a touch faster. Did find this on anon Europe website. CFexpress V90 UHS-II SD Max transfer speed 1.97GB per sec 321 MB per sec reference here.www.canon-europe.com/cameras/eos-r5/professional-performance/ So we have the internal write which is the shots before the buffer wall and then the clear off is the transfer speed. So that's where the faster CFexpress help. Its all voodoo really lol
@@WILDALASKA my day job is working for a storage vendor (petabytes for clouds) and it’s interesting to see how things are implemented in the camera world. Even with that knowledge it’s still seems like voodoo to me as well, there are too many things left up to the vendors imagination in the cfexpress and nvme specs :)
Ok great information Scott. But for this poor wildlife photographer shooting the canon R6 mk.2 what card do you suggest. My pro grade v60 keeps stopping on video after like 10 seconds saying slow write speed and in stills even in mechanical mode 12fps if I hold for half a second seems like way to long of buffering. Same in electronic mode 20 and 40 fps with diving osprey and I'm literally just making super quick little bursts. Any suggestions fir the R6 mk.2 without spending 400.00$ Thanks my friend
Thanks a bunch, was going to buy the delkin black as it's a cold card and I'm sure of that, and it's durability, but does the Exascend Essential 1TB get hot in camera, especially in the nikon Z8? Thanks.
No more than the Delkin. They only really get hot when you shooting 4k60p or higher video resolutions. In still they don't get hot. The card feels tougher than the Delkin and performs as well. I was really surprised.
This is an awesome video!. Some very interesting findings. I'm very surprised that the Z8 actually all performed Z9 in terms of buffer I wonder if that's a sample variation. Did you get a chance to try the high efficiency files? I find that it's very hard to tell the difference between uncompress raw versus a high efficiency so I shoot high efficiency most of the time. It will probably never run out of buffer in high efficiency mode.
HE will shoot just forever pretty much. I shoot RAW lossless on all my cameras just to get more out of DXO Pure Raw on ore-processing my photos. Yes the Z8 doing better in buffer was interesting also. My sample of tests was a min of 10 clean runs. But on this part I did more and will be doing more tests to verify. Ben checking settings on both cameras also, but o fa they are the same. More Z8 content to come ;)
@@WILDALASKA thanks for doing this. I've tried using LR and C1 to see if I can find a different between loss lossless and HE and honestly can't tell. What are you seeing as the difference? In the Z8 vs Z9, I wonder if some small setting is affecting it. They should be the same. Maybe try both in manual focus and manual exposure? I don't know. So weird.
@@WILDALASKA Thanks. Will add it to my list. Appreciate your review - not many out there on this yet. I noticed that at Adorama it was listed for over $700, while at B&H it was listed for $469. Did prices recently drop? Again, thank you for taking the time with this.
as stated in the video I have been using the card in the field for several weeks. And to get numbers you have to control the image or the file sizes change
AFFORDABLE but heat dissipation is weak. i returned mine. After 10 min of very light photo shooting outside, 30 degrees, i get hot card warning. unacceptable .
on what camera? O the Z9,Z8, and R5 I ran this until it ran out of memory at high frame rate video and none gave me a heat warning or were anymore hot than the Delkin Black. This was the 1TB Exascend.
Wait for 15 years Nikon Z8 cameras still do not have flip screen to vary-angle selfies, body size and weight are big and heavy, Canon vari angle flip screen attracted many buyer and occupied more than 50% sales, tilt screen are not favorites toy many photographer, I have to change to Canon for R6II camera which is lighter and have vary-angle flip screen.
