Sony A7 IV - Do You Really Need a CFexpress Memory Card?

Answer is YES

Cf is ssd speeds in sd form

Thanks Tim

great and very clear short video, thanks and subscribed

Very informative! Thank you.

Nice Reviews. One question, can you use a cfexpress card and a v90 card for simultanious record such as back up. I want to use the cfexpress as main then v90 will be as a back up? Hope this make sense

Alpha Shooters ))) That is hilarious

Tim I’ve just received my Sony A7m4 but when I tried to upgrade the software using the CF express card it wouldn’t fit the slot in my computer
Could you help please as you have taught me everything I know so far

These CFexpress type A cards make me mad. Sony has a great camera lineup but the type A is the weakest link in all of it. Type B is more mainstream, much cheaper, faster, and has more storage. It's just head scratching and the only reasoning for type A over B is greed.

Thanks Tim, this was extremely helpful!

I'm currently using a prograde v90 UHS II 300mbs card to film on 4k 60 at 600MB

Video shooters/Still shooters….. is that all shooters 😂

Hello ! Good video ! In s&q mode 120 fps, 1080p 10bits, do you need CFexpress? V90? or V30 ? Thanks a lot :)

Lossless compressed will hit the buffer with a V90.
Compressed raw will not.
Seems you confused these two in the video.

Very helpful and informative - thank you.

how long videos can we shoot using CF 80gb, at 4k 50 fps max bitrate?
Great video, helped me a lot. EDIT: I found this info in your quide. Thank you

CF express it is... Spray and play time lol

Do you find faster performance when mass deleting or mass protecting files using the CFexpress cards?

what's the difference between cfexpress type a and type b?

OMFG THANK YOU SO MUCH!!!!!

In your memory card guide it says that in compressed raw it hits buffer after x shots on the Kingston uhs2 cards,
But in lossless compressed it never hits buffer ?
Is that right ? I don’t understand how that’s possible, the lossless compressed files are a bit bigger than the lossy compressed, and more computation needs to be done I imagine.

Oh is it because of the drop from 10 frames compressed to 6 lossless compressed ?

I previously thought uhs ii cards were out of my budget but the Kingston ones you showed on your website look like a great deal, thank you! I’ll purchase through your link.

Can you compare the image quality between uncompressed raw vs lossless compressed raw? Thanks a bunch!

If you film 4k60 XAVCS in video mode then interpret footage in post, can you get by without the cfexpress.
What is the benefit in S&Q vs just interpreting it in post?
Or maybe I am completely Amatuer hour and missing out on the s&Q function.

The buffer simply hits too fast with a v90 card. Given the card speeds, it shouldn't fill up so quickly. Now I have to make decisions in terms of workflow to see which card I need to prioritize when I'm shooting.

Can't wait till you test it with 200-600mm for birds in flight 😎

so a v90 card will rec all codex apart from s&q.......one more thing when I play back on my samsung tab s7 in 10bit 4.2.2 video it doesn't work as well but chopy a stuttering. or sometimes just audio. and help will be greatly appreciated. merry Christmas

Hi. Very informative video. The one thing I cannot find anywhere is how many shots can I take if:

-shoot compressed Raw
-use 2 V90 SD cards writing simultaneously

I’m a wedding photographer, so that’s the most important burst spec I care for. Thank you so much

good data... thanks

An amazing camera for the money ! Despite the card costs ! 👍😍
