just used a Transcend 64GB card and it seems OK so far but time will tell...

Rob may I ask why you reformat the cards after you use them?
I have 3 Transcend 133x cards that I use and I only delete the files once I transfer them to my PC. I never had a problem with so far, so I don't see the point of reformat the cards.

There is no need to reformat at all.
Never have done it, and never had data loss.
Shooting on sony cards only tho, I know way too expensive but in my twisted logic it gives me peace of mind. So I reckon that is worth the extra money....

not reformatting - however, interested in whether we're talking about 'quick' format, or full format?

i made the mistake early on of deleting files off card from pc - when i put the card in the camera i got a 'format error' on the little display. there's NO way to format the card on the camera with is error!!! put it back in pc, did a quick format and all came good again.

Stelios, I have done that since day one and haven't had any problems. Since everything went well I never changed the habit. Since everyone was talking about not reformatting the disk, the last 3 jobs I've done I just used the delete feature. No difference.

Thanks for the reply guys and Rob,
The Photographer that I work with, tells me that he always format his cards used in his DSLR camera because his says that when you delete the files only, your card is not completely empty (less space available) so he always formats his cards after he transfers the photos to his PC. Any comments.

Stelios

That actually makes sense. As long as you format in the unit I really don't see how formatting the card causes problems.

Sandisk card types for MRC
 

Hi, I am looking at the below 3 card types for the MRC.

Sandisk_Extreme_32Gb_UDMA_60Mb/s_$173
Sandisk_Extreme III_32Gb_30Mb/s_$172
Sandisk_Extreme PRO_32Gb_UDMA_90Mb/s_$311

Any views on Extreme vs Extreme III vs Extreme PRO or UDMA vs NON UDMA. Would the Extreme PROs be overkill? Which would you recommend?

Colm

I have nine of the Extreme IIIs and they have all worked flawlessly. I'd buy more but I can't find them anymore.

Colm, The Extreme 60mb/s card is great and fast. Not sure if the 90mb/s one is worth the extra cash at the stage.

so for wedding services its basically not possible to record onto CF? Well... it's possible but not recommended? Maybe the hard drive unit is recommended over the CF for this sort of thing?

Nonsense. 32GB cards work fine. This misinformation was addressed in the post following the one you quoted.

It still seems like there is a matter of opinion on that issue. I know several people have had 32gb and 64gb working but from what I've read a lot have also had problems.

As with most people switching from tape to CF will hopefully give me better reliability, I just hope there are no issues with larger cards. I'm sure the issues ive read about are due to the specific cards and not because theyre 32gb

Don't think about what a good card for the Z5 is, think about what a good professional card is.

Still photographers probably use the most compact flash cards, trust the brands they trust. Walk into a photography store that is for professionals (not one pretending it is for professionals) and look at what they sell. I'm guessing many of them will only have Lexar & Sandisk.

If you stick with quality, you'll get quality. As to 32GB, 64GB, 128GB... why do you need such big cards? If there is a risk with a larger card use smaller cards & swap them out.

How many people are recording w/o a break for longer than 70min? If you don't, stick with a bunch of 16GB cards. They're small, cheap & well trusted.

I have 2 16GB & 2 8GB, rarely do I need more than that.

If you address that question to theatre/live event shooters, the answer is quite a few. In the past five years we have yet to have a show where Act I was less than 85 minutes.
