Pentax Q UHS-1 Compliant?

Biro · 09-03-2012, 06:57 AM

I'm pretty sure the Q is not UHS-1 compliant but I'm posting this question anyway just in case anyone knows for sure. There is no reference to the UHS-1 standard anywhere I've looked in the camera's manual or in online reviews. I ask because Amazon has a Labor Day special on the SanDisk 16gb 45mb/s class 10 UHS-1 card for $17 each. I'm trying to determine if it's worth it. I may still pick up a couple of these for other cameras that I own. I suspect these are the same cards labelled as Extreme Pro only a year ago. On SanDisk's own website, it looks like the Pro label only goes on the 95mb/s cards these days.

SD, SDHC, and SDXC Memory Cards
The PENTAX Q is compatible with the latest generation SD, SDHC, and SDXC** memory cards for ultra-high capacity storage as well as outstanding image file portability.

** Not compatible with UHS Speed Class transfer rate

So they work, but not faster.

That's right. There's no question that they'll work. But you'll be reading and writing down at 20-30mb/s. That's what I figured.

I don't see how that is a problem since you still get full UHS-1 speed when using a USB 3.0 card reader to upload the files into your PC .

It's not really a "problem" per se. But it's nice to be able to use the full card speed for things like clearing the buffer quickly and keeping shooting speed up while in burst mode. Still, I'm picking up four of these cards for two of my cameras. At least I'll know if there are any limitations in this area it won't be due to the card. Ironically, I usually off-load all of my images directly from the camera with the card in it. The time it takes to take the card out and insert it into a card reader generally negates any speed advantage on the part of the card.

is that also the reason why the the usb transfer speed on the Q is that slow ?!
i mean not fastest hardware etc ... because i got 4mb/s on the Q and 17mb/s on the k-x via usb ... really sucks if u transfer videos/20mbs raw files ...

Not a problem but will affect your interval shooting if you want to use raw and a shorter interval.

Probably yes and that's a good reason to use a USB3 card reader...

i dont own any UHS-1 cards and my sandisk cards are outperformed of my usb2 ports ... but the 4mb/s of the Q is horrible

I use a UHS-1 Transcend 16GB card in my Q. Works well but I couldn't tell you if it is faster than a standard card since it's the only one I use with the Q. Worth it for faster downloads to the PC though. I shot RAW and RAW+ on it a few times and was surprised that it didn't seem that slow saving (on firmware 1.13).
