8GB Extreme IV CF Cards

If it wasn't on Amazon, I'd say that was too good to be true so steer clear.

Do you think someone's confused Extreme III and IV.
 
Yeah i thought that, seems like a very good deal, gonna order 2 myself for that price.

Chris.
 
dispatched in one to 3 weeks. sounds like it is out of stock to me.:shrug:

price looks good though
 
Very odd, I clicked on the link and it came up as being supplied by Amazon at £52.48 so I ordered one straight away, with the order window open I clicked on the link again and it is showing at £73.35 from Memory Zoo.
 
This is very strange, i ordered 2 at the original price and have had an email confirming it so will wait and see.

Chris.
 
Just rang amazon and they confirmed that 2 are already in dispatch ready to go, looks like an error on thier part. Lucky me :woot:

Chris.
 
If you click the link, it shows £73.35, and supplied by Memory Card Zoo. BUT if you look at the right hand side of the page under more buying choices, it shows Amazon selling at £52.48
 
Looks like it is back in stock. Still cant justify paying out for a new card though so I dont know why I was looking :(
 
Bought one of these from Amazon a couple of weeks ago. Was showing as out of stock with a three week wait, but mine arrived after a week. Genuine article, and very quick to clear the buffer in my 50D - about 4x quicker than my 8Gig kingston/cheapy cards. Not much quicker than the cheap cards in my 40D though, so check if it is going to make much of a difference in your model of camera before purchasing. (In real life usage I have found no difference between an Extreme III and an ExtremeIV in my 40D.)
 
just ordered 1

"Total for this order: £52.48


Delivery estimate: 21 May 2009 - 26 May 2009
Dispatch estimate for these items: 18 May 2009 1 "SanDisk Extreme IV CompactFlash 8GB Memory Card"
Sandisk; Electronics; £52.48"
 
Email this morning, 'we have dispatched your items'.
 
Gone and ordered 2 of these! Uber-bargain :D

Thanks for the heads up.
 
Delivered this morning.
 
Not wishing to pour cold water onto this thread but ..... I purchased a Sandisk 4Gb Ultra II card via Amazon about two years ago. It failed about a year ago.

I got in touch with Sandisk for a replacement. They asked me to photograph all six sides of it which I did and they replied saying that it was a fake. Amazon didn't want to know as it was outside of their warranty period.

Suggest you make every effort to check out the authenticity of any card as soon as you can.

I don't want to rain on anyone's parade here, but I hope you guys understand that many cameras will gain no practical advantage from cards of this speed, at least according to the test results on Rob Galbraith's site. e.g. the fastest speed a 40D can write out at is around 11MB/s and an Extreme III is pretty much just as fast as an Extreme IV when used in the 40D.

The 1D3 is a little quicker, but I doubt it can benefit from these EXtreme IV cards either.

1D3 CF card speed results - http://www.robgalbraith.com/bins/camera_multi_page.asp?cid=6007-9038

The 50D, on the other hand, can pump out files at 33MB/s with the right card, but on these older cameras the faster speed is of no value as far as buffer clearing is concerned. Of course, download speeds will be quicker, but it's a big price premium for (IMHO) little worthwhile gain.

FWIW I have a 1D3 and a 50D (as well as a 30D and 40D) and I chose to invest in capacity rather than speed and for similar money (£54 each) I have 32GB 133x Transcend cards and their "slow" speed does not impinge on my shooting. My pocket sure notices the difference though!

EDIT : p.s. If you don't fill your camera's buffer when shooting then you will not benefit from a fast card while shooting. There may be benefits when it comes to downloading the images later.

Via Amazon or direct from Amazon?

Well, yes, if you have a D3, D300, D700, 5D2 or 50D (even some Sonys), but some of the posters in this thread appear to be using 40D and 1D3 cameras and as such are unlikely to see any benefit, while shooting, from these fast cards vs an Extreme III.

Of course, they are free to do whatever they like, and if they think that's a wise way to spend money then more power to them. I only mentioned it for the benefit of others that might get sucked into the hype without realising the marginal gains that might be had, depending on the camera body.

The cards in that test, are they UDMA?

That seems an odd question. The cards are whatever the cards are. Some will be UDMA some may not. If you click the little "+" sign to the left of each card listed it will expand with more information, including whether the card is UDMA or not.

If you look at the figures for the 1Ds3 and compare the results from the Extreme IV and Extreme III (30MB/s) you will note that there is almost no difference in write speed - 18.2 MB/s vs 18 MB/s for raw files. Both cards are UDMA. (JPEG writes are actually slower on the Extreme IV ???)

It appears that the test results for the 1D3 were made before UDMA cards were available, so there may be room to improve on the results shown in the table by using a faster card. But I doubt very much the 1D3 will perform any better than the (newer!) 1Ds3 in terms of writing performance. In fact, the 1Ds3 does write out a little quicker to the card that came top in the tables for the 1D3.

I don't know what the price premium is of the IV over the III but personally I doubt it is good value IF YOU HAVE A 1Ds3, 1D3 or 40D (or less).

Its not all about write times to cards, reason I use the IVs is faster write time to my computer when I'm downloading.

The difference between the 3 and 4's is really noticeable when waiting for 32gb to download ;)

At £52 they are a steal, I bought my first 1gb card in 2003 for £400! (Had to import it from the US as Je-ssops were doing them for around £900)

Agreed. The real benefit for going to faster cards is for uploads to your computer and even then, you really need to be looking at a firewire card reader as USB doesn't cut the mustard.

I'm curious. Why do you have to wait for 32GB of files to download? Can't you start work on the first couple of dozen/hundred images long before the last image is off the card? The rest can carry on downloading in the background.

An Extreme III 30MB/s card should net me around 100+ raw images per minute from my 1D3. I know I can't review/process images faster than that. I certainly don't need the 1000th image to be on my hard drive before I can start work on the first.
 
Can a mod please lock this thread now as it's becoming too much of a debate when i was only pointing out what i thought was a bargain.

If you think the card is good value buy it, if you don't then DON'T.

Simplez ;)

Chris.
 
If you're not that concerned about the speed difference twixt the IVs and the IIIs (30MB/s versions) then you can pick up a 16GB III at Play.com for only another tenner.
 
Cheers Skyline ... just bought one for my D700/D300.

Cheers too Doddy for the speed advice ... I agree pointless 'bargain' for some but they may upgrade some day I guess - maybe when these cards are £10 ;-)

They have UDMA written on them for the guy who asked above.
 
Just bought one of these after I got ripped off from an ebay seller selling fake Extreme IV 8GB's. I actually got a refund quite quickly and the seller apologised saying they were unaware.

Will wait for the amazon card to turn up and order another if its a genuine one.

I heard that before but they carried on selling them for weeks after I had told them.
 
So has anyone got theres through yet?
Are the the real deal? Or not.
