Deals on CF cards

lol i say ignore it. Im using, as already stated, the Sandisk ultra 2 CF cards, at 15mb/s. Works like a charm, and shot a couple hours already of stuff. Not one problem.
 
FYI I got a dropped frame or two with the x133 Scandisk at abut 45% full... $%&#$$!@*&%@!!!!!
:badputer:

Maybe it is time two sway out the two 32GBs for one faster card?

I guess what so many have observed...that you don't need UDMA for video recording on the 7D...should just be ignored? And the Owner's Manual that specifies 8MB/s (IIRC) and doesn't mention UDMA in the chapter on video recording should be ignored too? And the published data rate of 5.5MB/s...ignore that too? :Drogar-Thinking(DBG

Real world use has shown that UDMA is not a requirement, but there are theoretical benefits to using these cards that I haven't seen anyone manage to disprove yet -- should also be noted that outside of the statements by the Canon rep, no one to my knowledge has proved or documented problems with using slower cards, outside of the inability to take stills while shooting video on occasion.

Unless we get into some kind of conspiracy theories about backroom payoffs between memory companies and this Canon rep (who is not a small fish), there is little reason for him to advocate for UDMA unless he believed (or, as he stated, saw) a reason to using UDMA enabled cards.

For this reason, if I was on a paid gig I would want to be using fast UDMA cards just to be absolutely sure my client was getting the best image out of the camera. Specifically I would be using UDMA no question for weddings as well, for the ability to comfortably shoot a still during video. Are they necessary? Obviously not. Is there a peace of mind vs. cost of expensive memory debate that every shooter can legitimately have with themselves? Yes! And that's for you to decide.

For personal projects I'll probably get a 32gb relatively no name, for paid work I'll use speedy name-brand UDMA cards and wait for deals to accumulate a nice staple of those.
 
The older sandisk extreme IV's are 40 MB/s the newer ones are 45 MB/s both are UDMA. The label on the older one doesn't say UDMA but the FAQ on sandisk website confirms that it is.

The rebate I mentioned in post 45 should apply to either but I don't think the older ones are on sale any more at the stores that support the rebate.

Please forgive another stoopid question but what does UDMA mean in layman's terms?

I've been using the non-UMDA cards Most of the time I'm fine. But there was this one long 10-minute clip I shot that somehow got corrupted on the Compact Flash card itself. If I had a UMDA card would I have lost this clip? Hard to say what caused it.
 
I picked up a Maxflash 16gb 233x card for about $55. So far, no problems. Has anyone used or heard of this card? Reliable?

Canon's product manager has drawn that line -- he said you need UDMA.

And that is hogwash from what I can tell. The business my family owns is a security consulting firm and one of our clients in Frys electronics. Being on good terms with the managers there, I was able to get a few different CF cards for testing on my 7D. I already had a couple 32gb Kingston 133X non UDMA cards and we tested a couple non UDMA 150X no name cards and two UDMA cards, Sandisk Extreme IV and Lexar Pro.

Didn't bother with stills because the issue there only seems to be with high FPS continuous shooting.

In video mode, there was no discernible difference in any of the stuff. No more artifacts or noise. Nothing. I think if you can afford the UDMA cards, go for it...but if price/capacity is more of a concern I don't see any reason to bother.
 
Happened AGAIN today!! @%&#@#^@#!!!!

Not sure if it was the same one or not. But both times 1080/24.

Couldn't have been heat or buffer cause I had just started it up... This is not looking good Scan't-disk...

What is the best deal on the next step up in terms of speed?
 
Many moons ago, we used to occasionally get cases of videotape that seemed more prone to dropouts. You can get a soft "copy" of a lens. Some 7Ds are showing up with dead/hot pixels. Maybe your card is a dud?
 
I need to reup on cards for a shoot asap. Prices are higher than they were a month ago.

Is anybody using these cards ????
According to 'on paper' specs they should be ok. Can anyone post experiences/ problems?

FYI, I got two 30MB/s 16GB Skandisk Extreme III's and ZERO buffer warnings yet, of course no dropped frames either. Over one week and going strong. Probably filled each four times so far. :thumbup:
