Delkin 512GB CFexpress Type B 4.0 Memory Card for Digital Cameras | Ideal for Express Transfer of Images and Videos for Storage | 512GB Memory Card Storage

I recently moved from a Canon 5DMarkIV to a Canon R5 MarkII and all my old memory was either too small, too slow, or had a know conflict with the new camera(certain SanDisk memory cards have issues with the Canon R5 MII). So I needed some new memory cards and since my new camera has a slot for the newer CF-Express cards I wanted to get one for wildlife and sports photography purposes. The CF Express memory cards are exponentially faster writing than the SDXC cards, allowing the camera to continuously shoot for a longer period before filling the buffer. With a regular SDXC card I would fill up the 70 photo buffer in 1.5 seconds of shooting or less, and then it would take 5 to 15 seconds or more to catch up and write the images to allow more space. This card however allowed me to shoot continuously for much longer, and even when the buffer is reached it quickly writes and refills the buffer to allow more shooting. I can't tell you how amazingly fast this card is, and so far has been very reliable with no issues over the 25 plus soccer and volleyball games I've shot. I was a bit hesitant due to not recognizing the name brand, I've alwasy been a SanDisk guy, but the reviews were good and the price was right so I took a chance on it and I've been extremely happy with the decision. So happy that I bought a second for weekends for when I have a tournament to shoot and need more memory. If you don't need the high speed aspect, such as a portrait or landscape photography, then you could probably just stick to an SDXC card and save some money, but if you need speed for sports, nature, or any other fast paced photography were you need lots of photos in a short period of time, then this is the card to get!

Popped two of these into my Nikon Z9, formatted them and that was it.. Took a bunch of test pictures around the yard and I think I'm all set. The real stress test will be when I go on a trip, but that's later. So far so good.

I use this card as the secondary write (backup in parallel) for a Canon R1. Shooting 30 FPS JPEG+RAW there is no issue with the card keeping up with writes. Card gets warm but never hot in the camera.

Worthy upgrade for EOS R5, I was tired of filling a 128gb card from sandisk, this definitely did the job for 4k video.

Using it with my Nikon Z8. No lag observed in last 2 months of wildlife captures. Especially 120fps videos are as smooth as butter. Surely recommended.

It’s great but there are faster brands. But this works well if it’s on sale. Used it with an R5 mark ii.

As advertised - fast and cool
