Hi Guys,

Quick post, I have a C500 which I love but thinking its time to trade up now to the MK2 for the auto focus and lighter setup.

The only downside is the 12 bit 4444 60fps is not on the c300MK2 i know there is 10 bit.. would of have been nice. Anyways, what is putting off is the price of the CFAST media.

What ones have been recommended now apart from Sandisk? What are my options, I know I cannot put a price on reliability.

Thanks
 
I have been using the Lexar 3500x cards, and they work well.

Transcend also has some cheaper cards--the CFX600 line. They are cheaper than the more commonly available Transcend cards. They also aren't on the approved list of cards, but I have a 256GB, and so far it has worked well. Problem is they are hard to find.

I have a Transcend 256gb CFX600 and it stops recording RAW in my C200 after about 2.5 minutes.
Your results in a C500 might be different.

That is surprising...I use those in Blackmagic cameras with lossless RAW CinemaDNG, which I think would be much heavier than CRL. Maybe that's saying something about CRL.

EDIT: Correction; I have the 650 version.

Yes, the 650 is a normal A-level card. But I use a 600 in my XC-10 and it works well there. That codec comes in at 305 Mbps. But it won't work in my 1Dx mII at 520 Mbps. I find it very interesting that it seems reliable for drummondb—that's great price performance in that case. I think the C300 mkII comes in at around 420 Mbps or something similar...
 
I also use the CFX600 cards on the C300II. They work without issue. I also shoot double slot recording so it is nice to be able to get two of the CFX600 cards for the price of a single CFX650 card. Or it would be if I could actually find the CFX600 cards for sale anymore. They started out around $200 for 256GB, but it is now hard to find them at all and what do seem to show up are cards that have been marked up by a secondary seller.
 
I'm curious if anyone has tried heavy shooting with the Egodisk 256s in the C300 MKII? I've done several shoots with rented C300 MKIIs alongside my C200 but I haven't had the guts to try it on a high profile client shoot, I've just used rented Sandisk or Lexar cards with the C300 MKIIs and my Egodisks on my C200. Even Egodisk says that they aren't really recommended (yet) with the C300 MKII. Interesting that the CRL on the C200 is a lot bigger data stream than the XF-AVC at 410 Mbps on the C300 MKII, yet we're not yet sure if the Egodisk will work with the C300 MKII. I'm pretty convinced that there is a lot more going on with CFast 2.0 cards than just data read and write rates, there is some stuff with handshakes, and buffering that mean that there are plenty of CFast 2.0 cards that "should" work with a given camera and don't and some cards that on paper, are not certified for a given camera but work fine (like the Egodisk 256GB, which are rated at the VPG-130 standard).
 
So I have an ego disk 256 and a C300Mk2 . I have shot a substantial amount of 4k 24 fps and 30fps with that card and have had no issues. I have also shot various flavors of overcrank with this card 1080 - 60 and some higher crop frame rates up to 120fps. No issues.
I had a friend with a Mk2 message me with concerns yestrday because he has had some buffer overruns with ego disk cards which resulted in a bit of data loss.
After he messaged me I used Black magic speed test with thunderbolt 1 card reader to check out my collection of Lexar and ego disk cards. All cards came in with a 328 to 330 MB/s write speed. My buddy did the same test with his ego disk cards which came in at speeds of around 262 MB/s which is about 20% lower than my cards which could explaing the buffer over run errors he was experiencing. Canon also told him the cards were not approved for c30 Mk2.
I’m curious if anyone else has had trouble with ego disk cards when shooting with the 300 Mk2?

Interesting. You could go back and research, somewhere there are some posts where DVXers bought the newer series Egodisk (I think the 512 GBs?) and ran into buffering issues, but I can't recall if that was with the C200 or C300 MKII? That's why I have only bought the older, original 256 cards. I read at least two reports of people having issues with the 512s. No issues shooting CRL with the C200 with my half dozen of them, so far, fingers crossed. I think I will avoid using them in the C300 MKII. I don't own the C300 MKII so I only rent them and if I am renting one, probably smarter to use the approved cards I would rent too.
 
I have four Transcend CFX600 256GBs that I use in my C300 Mark II. They've all worked flawlessly for the entire time I've had the MkII. I ordered mine from Amazon UK... they worked out to about $200 each shipped to me in the USA.

Only thing that's odd about them is they go into the camera and readers what feels like upside-down. In talking to Transcend, this is normal for this card.

Egodisk cards work the same way. Not sure why, but they just seem to throw the label on the opposite side most companies do.

Part of getting 'approved' by Canon is also brand consistency. F.ex. I know people who says they have never had any issues with their Lexar 3400x (which were never approved), and I know people who've lost two 3400x Lexar cards on the same day.

I would be slightly skeptical about the 3500x & 3600x Lexar cards that are now circulating. They could be good if leftovers QC'ed by old Lexar that came out of s rumored warehouse somewhere. But don't know.

I have Sandisk (128 & 256) myself and they have been flawless! Not a single frame lost over two years in.

Hoping the ex-Lexar guys do well and that their cards get approved! Read one test that indicates they should meet Canon's spec (although not so sure about meeting Arri's spec).
 
Sure would be interesting to know how the process for getting approved by Canon for media works? Do the card manufacturers have to submit samples to Canon? Does Canon just go out and order some cards and test them? How do they test them? Is it all done in house or buy Canon users via Canon? So many questions...
