This should work too right?

I live sonnet stuff having used there cards in my Mac for many years.

I tried that one back when we were all trying to find out which adapters would work. I found it didn't work.

Thanks Keith.

Tested
 

I have tested yesterday, with the SDHC adapter. Worked fine in all modes, but don't have the ability to overcrank, like the Transcend and Sandisk.

I have 5 cards of Sandisk 16GB Ultra II class4 and also 5 Transcend 16GB class 6. In some strange way the all those Transcend cards have been playing me for a sucker. Sandisk cards work perfectly but with the Transcend cards I keep getting "unknown media errors" and "unreconizable media" and what have you.

I actually haven't lost any data, and all the Transcend cards do work after changing them between adapters and "restoring data".

I have 8 Transcend 16gb class 6 SDHC cards. I haven't seen what you describe.

Where did you buy these cards?

I bought them from a reputable internetshop in Germany.

I don't know if it's been mentioned in this 96 page thread yet, but the idea of putting those Express Card adapters together with one of those nanoFlash units that Convergent Design is coming out with in June could be an utterly fantastic combo - high quality 4:2:2 recording on CF, with "low quality" backup on SDHC, and cheap as heck (after biting the bullet to pay for the nanoFlash unit).

e-films MxR + 32 GB Transcend SDHC works
 

Just for the record, I'm using the e-films MxR adapter with 32 GB Transcend SDHC card (Class 6) and it works fine up to 720p50.

Just to remind people, frame rate is irrelevant in normal HQ recording as all frame rates and size are 35mbps VBR. It's only in OVERCRANK that frame rate increases data rate.

720p24, 1080p30 or 720p60 all the same data rate.

At HQ and filling the entire card? I can record for 30-40 minutes on a blank card before getting a media error on my Transcend 32GB Class 6. Several cards, several MxR adapters. Cards work flawlessly at SP. Transcend 16GB works flawlessly at HQ. My advice: beware if you're doing long-format recording.

On a related note, anyone else notice that new 32GB SxS cards have dropped to ~$850? Looks like Sony pulled the 16GB SxS cards, and Sony's new 32GB are now only ~$200 more than SanDisk's current 16GB SxS offering. Still a lot more expensive than the MxR/MxM route.

Hi Phil, welcome to the video club :-)

The problems will start when you try to overcrank with Transcend cards, the standard USB transfer (as used by SD) can't cope with the higher transfer speeds required for overcranking. I tend to use the 16gb cards just to keep the data safe.

Overcrank on Sandisk Ultra II vs Transcend class 6
 

I filmed a documentary in India and in the USA using the EX3 and sandisk Ultra II 16Gb cards + a Kensington card adapter.
What Ive found after having shot roughly 80 hrs of footage is that overcrank upto 50/ playback at 25fps HQ 720p/25, seems to work absolutely ok on the Sandisk 16Gb cards.(even going upto 1 minute of recording slo mo),

The Transcends are another story, same adapter, I noticed straight away that overcrank works max upto 48/25, on these. Other wise it says media error.
Not sure why that happens, havent experimented going above 50/25 for the Sandisk though.

Jvc ka-mr100g sxs
 

Does anybody know if the Kensington (or any) adapter will work in the JVC KA-Mr100G recorder? MXMExpress told me their card won't work in it.

I picked up the MxR cards (these are great) and then bought 8 Transcend Class 6 16GB SDHC cards. I have found one SDHC card out of the eight that will start recording clips normally but before if is half full it will fail (every time) and need to be restored. I've done multiple re-formats on this card and always re-formated the card if it has been read by my Mac.

So I'm double checking all my SDHC cards to be sure there are not other cards with a consistent problem like this.

Now I'll try to exchange the bad one...
