My uncle just bought an EX-Z750 and I want to get him a high speed 1GB SD card as a gift. I can get a 60x for $45 or an 80x for $65. Does anyone know if the camera will benefit from the extra speed of the 80x, or will the speed of the camera's internal circuitry limit the performance?

If the shot-to-shot time will not be any faster with the 80x card, then I couldjust save the $20 and get the 60x card.

Thanks for anyinput you have!

-Jeff

imo, the 60x speed is fast enough

i also have a question about high speed cards...i heard that in the 640x480 fine mode, you can get dropped frames w/a regular card. Is it really bad enough to affect videos? is there anything on this camera you can only do with a high speed card



PS. J Lee, where did you find a 60x high speed card for $45?

Hi, I bought a 1GB Corsair 40X - It is absolutely fine with no delays or lag.

Just to clarify - a lot of my use is 640 X 480 fine mode, some videos being up to 10 mins long with no problems, delay or lag.

afro_ninj4:NewEgg has a Patriot 60x 1GB SD card for $61.95 plus a $15 mail-in rebate (so technically not $45 but $46.95)

ufitsy: With the 40x card, are your shot-to-shot times the same as the 1.2 sec/shot that the reviewers are reporting when using 60x or faster cards? I'm just wondering at what speed the SD card becomes the bottleneck.

I read somewhere that you do not need the high speed card for the MPEG4 that Casio uses. Wish I could dig up that review again. Been contemplating getting a 1 or 2 gig card.

Wow, an EX-Z750 for $368 at Newegg...

1. Get a fast (usb 2.0 or firewire) card reader.
2. A spacious hard drive
3. Format the SD card
4. Close all other apps as possible, esp anti-virus apps.
5. Copy a very large e.g. > 100MB file by e.g. zipping a large folder, from/to the SD.
6. Measure the time t taken (which is the sum of SD, cardreader & HD read/write time)
7. Assuming HD & cardreader times are negligible
8. SD speed = 100MB / t

(Only accurate for the 1st time copy. Subsequent copies may have been cached).

Anybody has better measuring procedure?

its the review at dcresource you are talking about, i believe. It mentions you dont need a high speed card. However, I heard on some other reviews that if you use a regular card you will get dropped frames in the 640x480 Fine movie mode...

So here are my questions

1. does using a regular speed card make the Movie mode any worse? (i.e slow, choppy)....on any resolution and speed

2.are there any features that u can only acsess with a high speed sd card and not with a regular card?

3. does using a regular speed card make things like, continous shooting, power time, or shot to shot time any slower?

To be honest I don't have an S500, but a Kodak v550. But I believe SD speed effect on every DC is the same esp when they are both taking 640x480 mpeg-4 movies. So to answer ur q in general:

1. v550, using Sandisk "normal speed" 256MB bought 2 yrs ago, does NOT drop frames. It simply STOPS at 30sec, and REFUSES to continue, COMPLAINING THE CARD IS TOO SLOW. Also I believe the spec of mpeg-4 will regulate the bit-rate and does NOT allow the implementor (Casio/Kodak) to drop frames.

2. no idea

3. On v550, sandisk normal 256 vs ultra II 1G, shot-shot improves from 2sec to 1sec. Not yet tested "continuous" (burst-mode in kodak's terms). But I think won't be affected. This mode uses the internal hi-speed cache rather than the SD, and then copies the whole sequence of pics to the SD i.e. you simply wait longer after a burst.

But I heard from my friends having both Kingston ElitePro & Sandisk Ultra II. And they found Kingston performs better on Casio.
