Sam, your card should be fine. That is strange that you are only getting 8Mb/s in the camera. I have a pny (I believe) 35Mb/s card from some retail chain store (best buy, walmart, I forget...) and it usually getting around 19.5Mb/s. (by the way, don't expect much more than that. If you do switch brands, you don't necessarily have to get anything that is extremely fast as the camera can't output that fast. I assume you have the 550d.

Yes I have a Canon 550D, with a 18-200mm lens.

Yeah seems like it might be a dud card.

It is only doing 6MB/s write in the reader in my iMac.

I have a warranty claim in the SanDisk and they are being pretty helpful.

But now I know how easy it is I am starting to watch the price of a 50D on ebay.

One thing i am interested about is does the EXIF or meta data come across with a RAW recording into the DNG files.

It would be nice to know focal lengths and stuff (ISO, EV etc) of the end images, which could help with turnover of footage, otherwise you are going to need some pretty accurate pen and paper records while you shoot.

Hey Guys

I heard about your firmware a few weeks ago and thought I would try it out.

To me good colour accuracy and no compression is more important to me than resolution.

I work in visual effects so the thought of dealing with a stair stepped 8 bit moving image makes me shudder.

Anyway I put up a couple of tech tests stopping the exposure up and down with the firmware you have put out there:


My Cat, with fur detail which would get lost in compression



A bowl of fruit



It shows the dynamic range of the image, the compression artifacts are questionable, because you are looking at footage that is compressed out of Nuke and then compressed again in Vimeo.

Everything seems to work as it says on the tin.

What is a decent card to be using to get the maximum throughput. I bought a Class 10 Ultra SanDisk 30Mb/s Card but it scarely does about 8Mb/s in the camera.

Anyway hello from Adelaide, South Australia, I hope you are having a great day.
