If the topic was about the capability of the current technology, everybody would arm up and put on their math wiz game. Now that Canon give us everything we needed, it's all useless.why is a UHS-II SD slot suddenly useless?
When I first got my Canon R and used my old SD cards, the buffer would fill up pretty quickly. Once I upgraded to a 300mb (95mb-ish write speed) card, I've almost never filled the buffer, taking 15-20 burst photos at a time.Not true. If you are shooting high burst rate raw, then the faster speed likely will work with the processor to get you more shots in before the buffer is full, no? And, although not a huge deal, it is faster if you shoot 1000 raw files to get them on your computer.
When I run my 7Dii with both cards, if I accidentally set it to the SD slot, the fps lags repeatedly while it tries to write.
If you’re shooting weddings and you need that much burst you’re doing it wrong. If you’re shooting sports you’re going to be using a 1DX III.This camera represents a compromise between having a fully decked out pro body and cost. Also there’s no mention of bus speed for the CFexpress card. If it’s PCIe 2.0, then it doesn’t matter how fast the card is. If It is using PCIe 3.0 and they added a second CFexpress slot it would have raised the cost of the body even higher. 300MB/s is fast enough for 99% of photographers anyway. UHS ii is also backward compatible with UHS i so you can use your old SD cards if you want.Perhaps read what I wrote. Key phrases like "I imagine", "likely". And then separate facts such as 300MB/s vs 1200MB/s. Again, stay classy!
And also the price difference from a good SD UHS-II card and a CFexpress card is not too much. If you buy a 64gb 300mb/s SD UHS-II will be around 100/120€, the cfexpress Sandisk 64gb is around 140€ so the only positive is that if you already have the SD fast ones, you don´t need to buy more. I understand the option of Canon, but personally would prefer 2 cfexpress slots, though. I expect to use this camera for around 4 years, and i guess in 2 years SD will be declining...Not disapearing, but almost and being only in the entry level cameras. This is bad because manufacturers will also stop improving the cards...so you will have a "not so used" slot in 3/4 years. But well, it´s not a dealbreaker at all!Totally agree. Compatibility is good but, I would prefer 2 CFExpress card slots, even though I would have to buy them. It is like buying an expensive triathlon bike and putting a cheap water bottle that will increase drag because you don't want to spend the money to buy an aerodynamic water bottle.

And everybody is assuming that the 2 slot is for duplicated photos, being cfexpress in raw and JPG in SD. But there are a lotof people including myself that uses the 2 slots for raw. When a card is full the camera records in the 2nd slot.
I don't think this is totally accurate. It sounds like you are assuming raw to both cards, which I don't know why you would do that. If you shoot raw to the fast card and JPEG to the small card it shouldn't impact the buffer significantly should it?
There was a test of the 5D IV years ago that showed if you write RAW to both cards it is faster compared to if you write RAW to one and Jpeg to another. Presumably this was because the camera has to use processing power to create the jpeg. This could be moot with all the updated horsepower but it's something to check out when you get one.
however CFexpress in one slot and a much slower SD in the second slot will = write speed at the slower card slot speed such has been the previous case.Look at the 1dxmkiii recording specs. 10bit 422 and 12 raw at the same time. I guess you could call that a proxy but then again not really
max write speed vs CFexpress? why spend that money for that slot when the other slot is more than 5 times faster?
