Comparing Compact Flash Card types
The speed factor of a card is noce, but if your camera won't write at the
high speed, it doesn't matter. It's kinda like having a car that can go 250mph, but show me the city freeway where that is useful 9-5..... It may be hard to determine your camera's write speed to the CF also, but that is important to know if you are really going to shop around. Also, note that no standard exists for "12x" speed labelling. Unlike CDR where 1x is 150k/s (I think) and 12x is simple math, no such standard exists for CF, so note the actual speed, not just "12x". 640*480 movies; have you tried a sample yet to see how impressive this resolution is?(NOT!) That is what my Oly 5050 uses and it is very poor! Stamp size video is claer, but zoom in a bit so you can see the action and it is so pixelated as to be unviewable. I have a 256mb card and it holds something like 300 seconds of movie; don't think I have ever used more than 20-30 seconds.... It is why I still carry around my DV camcorder; it kicks butt over the OLY 5050 movie mode (and probably every other digicam although some are rumoured to be out that do still & movie well). Good Luck, Rick "Rick S." wrote in message ... I'm shopping for a high capacity (512MB or 1 gig) for my new canon S1 IS, (I want to use its 640x480 movie capability, necessitating high capacity). I see a few types on the market, I'm asking for info from those that have experience or knowledge. I'm leaving brand name considerations out, so as not to muddy the issue. So far, it looks like the only significant difference between type I and type II is the physical size; so if I get a type II it won't fit in my old canon SD110. No biggy, really, I've resigned myself to get a type II. The S1 IS takes either one. So my concern is that I believe that taking movies may REQUIRE a 'high speed' CF card, and the best I can deduce is that the regular type will write maybe 6MB/sec, 'ultra' will write at 9MB/sec, the 'extreme' claims 16MB/sec, but also has inernal recovery s/w if the card fails. A 512Mb CF card, roughly, goes for: regular type II, 100-125$. Ultra type II, 175$. Extreme type II, 250$ !!! Obviously, I'd rather not spend more money for speed I don't need, I would think there's a memory buffer in the camera that acts as a reservoir while it's filming, writing to the flash card as the flash card can take it. But if there's any risk at all that the card is the week point, I'm willing to spend the extra money for the 'ultra'. The 'extreme' sounds nice, but as we all know from the great 'steve's review' (and others) site, there is third party recovery s/w available to recover images from a failed card, so I'm dubious about the feature of internal recovery s/w. Please, talk to me! thanks so much, Rick |

I doubt that the S1 IS can write more than 4MB/sec, but you should check the specs. A 512Mb CF card, roughly, goes for: regular type II, 100-125$. Ultra type II, 175$. Extreme type II, 250$ !!!

I'd bet the camera cannot write anywhere as fast as the fastest CF cards. Still, check the camera specs. .... Of course, if you really want to take videos (of good quality), use a video camera. A cheap video camera will do a better job than an expensive still camera. Similarly, a cheap still camera will take better photos than an expensive video camera.

You, too, are spoiled! Grin
I love my S1 IS. I just got back from a trip, and I was very, *very* pleased with the photos I took. The toughest shots were from a boat, trying to photograph water skiers...but even those turned out wonderful (nice thing about digital is I can erase the shots of just the knees because we hit a wake). I was happy with the speed of the CF card's speed, and I was estatic with what I'd learned to do in just a week. Storing photos and taking photos in succession was not a problem, and I shot about 400 pics in 4 days; various settings, exposures and speeds. The CF speed was not an issue (SanDisk 256). I was thinking of getting just a couple more 256 cards until I tried to shoot a video...not nearly enough storage space, so I'm going to go bigger. I understand that I can shoot up to 5" of video with a 1gb card. Okay, then! All in all, though, I think this S1 IS is way better than the Minolta Dimage Z1. ~Kimberlee "y_p_w" wrote in message om... I've got a PowerShot S1 IS. I've played around with it using the slowest CF cards I own (standard SanDisk purchased in late 2002). It takes a long time before I can't take a shot. I supsect the camera has a large internal high-speed memory, and that speed of the cards won't be an issue in the camera unless you manage to max out the internal memory. It might be an issue in an card reader. My PowerShot S200 would max out quickly when bursting shots. With the S1 IS, I was able to get well over 20 straight medium 1 shots with fine compression before it refused to take any more shots. |

Try to make sure it's a high-speed card. I didn't think there was a problem with shooting video on my S1 using slower CF cards until last week. I took a couple of videos of people rock'n rolling to some pop music. When I viewed the videos on my computer, the shots looked smooth -- well, as smooth as you'd expect a rock's roller to look -- but the audio sounded terrible. It sounded all choppy! Dropped frames is not apparent in the video portion, but it must be happening based on what the audio sounded like. I have my sights set on the Transcend 40x 1 GB someday. The price seems reasonable compared to the other brands. |
