CHDK RAW file-saving time boosted + DNG option
Cool, the latest builds of CHDK have speeded up RAW+JPG file saving time now of 1.080 to 1.100 seconds on my camera. It has an option to display the file-write time on each shot so you can see the speed you are getting. Continuous RAW at 1fps up to the size of the card. Nice. They save RAW files directly to DNG format now too. Interesting new page of a few sample photos at their download site that were made using CHDK. http://mighty-hoernsche.de/samples.html |

I can set my D700 on 6.75MP basic jpeg & it does about 4fps without filling the buffer till the card is full or I can shoot 40 full size fine jpegs (or 22 raw) at 5fps in less than 2 seconds. I almost never use that but I don't feel limited :-) I doubt I would actually hold the shutter down for 40 frames at one time anyways g. Tsk tsk tsk ... someone, who prides dslr's RAW file saving speed Man, you got some weird math to make that look like a disadvantage. Even at 640x480 the S3 only does 2fps. |

Look at that, someone is conveniently leaving off that horrendous delay after removing their finger from the shutter button before they can take another picture. I bet you never noticed it because it gave you time to change your lens to the one you needed next, and then to go have a smoke. Tsk tsk tsk ... someone, who prides dslr's RAW file saving speed Man, you got some weird math to make that look like a disadvantage. Even at 640x480 the S3 only does 2fps. What have you been smoking? It does 640x480 at 30fps. Change the JPEG compression to level 99 or 3x and there's also no compression artifacts in any frames. |

Look at that, someone is conveniently leaving off that horrendous delay after removing their finger from the shutter button before they can take another picture. If you want 20-40 frames at 5fps there will obviously be a slowdown at some point, if you want 1 frame per second or 2, just set the continuous low rate default to 1fps, the default is 3fps. 1 or 2fps should be no problem with raw plus fine jpeg till the card is full. Lots of options, high speed up to 7fps with battery grip. Tsk tsk tsk ... someone, who prides dslr's RAW file saving speed Man, you got some weird math to make that look like a disadvantage. Even at 640x480 the S3 only does 2fps. What have you been smoking? Dpreview specs for stills, not video. It does 640x480 at 30fps. Change the JPEG compression to level 99 or 3x and there's also no compression artifacts in any frames. |

Tsk tsk tsk ... someone, who prides dslr's RAW file saving speed so as not to miss any of those "pictures" is now slamming a whole family of inexpensive P&S cameras that do it even faster with no slow-downs due to having to S-L-O-W-L-Y dump a dslr's buffer to memory-card every 5 to 15 seconds. Hate to tell you this, but those times for the P&S are crap compared to even several year old DSLRs. Mine will shoot raw at 5fps for more shots than I'll personally every need in a row. And after over 20 raw images at 5fps, only then will it slow down to what your P&S with CHDK can only do at it's max rate. If you lift off the shutter button for a bit, it goes back to 5fps for the next series of shots. But it's never slower than a P&S even after the camera's buffer is full. And it never stops shooting just to flush it's internal buffer to the CF card. Newer DSLRs that can make use of UDMA cards are even much better. You've got to try harder because with this post, you've only shown a glaring deficiency in P&S's compared to DSLRs. That's okay, you can use that huge RAW file-saving pause, during all the action that you have to capture, to try to change your lenses in time while that action moves somewhere else. By the time your subjects are in a new spot you might have that dslr lens changed in time. Even if taking single-frame shots, how many did you miss while waiting for that RAW-buffer dump? 10? 20? 30? Really, how many. You REALLY have absolutely no clue. Steve |

Really, how many. You REALLY have absolutely no clue. Steve I do have a clue. How many DSLRs do what you claim? How much will it cost them for practically no advantages in image quality? And has been clearly proved, image quality can even be worse in a "good" DSLR compared to a GOOD P&S. Let's see .... 5fps RAW for 20 shots or 1fps RAW unlimited. $8,000 (camera + lenses) or $300 (camera + lenses) ... decisions decisions..... Nikon D90: JPG+RAW burst, 4.5fps, 11 frames, time to buffer full 1.3s, delay time to next shots 8s. TRUE continuous RAW+JPG speed = 1.1fps. Avg. cost: $1,000 plus $1000-$5000 in lenses. Canon EOS 5D Mark II: JPG+RAW burst "up to" 3.9fps (not much better than their S3 P&S when saving JPGs alone), Avg. cost: $2,200 plus $1000-$5000 in lenses. Canon EOS 50D: JPG+RAW burst 6.3fps, 16 frames, time to buffer full 0.4s., delay time to next shots 42.3s (LOL!! Yeah, you read that right, nearly a minute of delay between shots). TRUE continuous RAW+JPG speed = 1 shot every 2.6s (LOL!) Avg cost: $2,300 plus $1000-$5000 in lenses. How's that for your "clue"? LOL!!!!!!!!!! |
