CompactFlash 800

I just got a Canon 1DX II and it records 4K video in a good image quality but horrendously inefficient motion jpg codec. i have a 128Gb CFast which was extremely expensive and is necessary for 2160/50p using this camera so ideally i wanted a higher capacity CF to capture a decent amount of lower 25p framerate 4K - so the Cfast can be reserved for 50p duties. Of all my existing CF cards though only 1000x Lexar Professional was fast enough to record 2160/25p - and at 32Gb only eight minutes worth. This 800x CF in the 256Gb looked to be extremely good value and having received it today appears to indeed be fast enough to maintain reliable 2160/25p video on the 1DX II. Obviously more complex scenes need more data but higher ISO also increases noise and encoding complexity: in early test at iso 12,800 the CF kept up fine so i am sure it will prove to be okay. The data requirement for a 3 min 6 sec clip was 11.4 Gb which is a write speed of 61.3Mb/s and should give me 64 mins of 25p recording (+ my 128Gb Cfast giving me 8 mins 50p).I don't expect it to be as fast as my lexar 1000x for recording bursts of raw stills but will be trying it in a Canon 5D3 at a wedding i'm shooting stills at tomorrow and should it perform less than reasonably fast that i expect from it I will update this review.

Great CF card. Decent size storage capacity - been in use almost daily since buying and not a single error. For a CF card, the transfer speed is very quick! Functions as it should, standard design and compatible with most CF products (check there’s no card size limit on your device first)

Arrived promptly, good card, works well with my camera.

I have used these cards for a year or so in my Canon EOS 7D, 7D Mark 2 and 5D Mark 3 and I have never have any problem with them.I generally remove the card and put it in the PC CF card slot when I download content to the computer and have always found them to work well.They are fast enough for writing photos and videos and seem really well made and reliable, so I think they are one of the best value cards you can buy.

Great for my 15 year old camera. Who wants microscopic SD cards anyway?!

Top Quality Card at a Real-world price

The SD card works great so far in my Canon 70D. Haven't experienced any problems. Great value for money.

Fantastic, reliable CF card. I use many 32GB Transcend CF cards for video capture, from the x133 up to these x400. All have provided bullet proof reliability over the years. Highly recommended .
