Dynax 7 Digital: Shutter Lag

Drudkh · 2nd January 2005

I have tested 7D's shutter lag and I am proud to announce that it has NO shutter lag at all!

Here's a picture that says it all!

EXIF:
1/125 sec, f/2.8, ISO400, Flash at 1/2 power bounced (ceiling).

I love my 7D!

Nice shot. Which flash did you use?

Thanks, was using 5600 I bought yesterday.

How about an ambient shot?

Cheers!

It's brilliant. They guitarist looks like he's seen Pete Townsend of "The Who"

I am sure every cam has shutter lag...

Anyway good capture... Actually wanted to go BG this morning but hesitated due to raining heavily this morning.. sianz*

Nope, I can guarantee the the shutter lag is almost zero. This is exactly what I capture when I pressed the shutter button and not before he jumps. UY79 can vouch for me.

It's all about reducing the lag or response time.

Steps like using manual flash ratio instead of ADI flash would reduce the lag significantly as it would just go off instead of doing a preflash first.

So far the D7D has been quite responsive, 9 frame RAW buffer has been more than sufficient and 3 FPS seems enough still for most situations.

Cheers!

Yeah, all cams have shutter lag, just how long/short it is, could be say 1/20 seconds (i pull this out of the air) etc etc... definately faster than prosumers which has in the region of 1/10 - 1/2 seconds... A1's shutter lag is around 1/5 seconds...

AND THAT'S THE PROBLEM... I'm too used to shooting prosumer, always anticipates, and thus trip the shutter before the action... and now on the 7D, i'll end up capturing something before the peak of the 'action'...

Oh and by the way if I forgot to mention, the phots I took of him jumping are not in continuous mode/drive. They are all single shot. I was waiting for him to jump, saw him jumped, pressed the shutter at the moment he's in mid-air and walah, there I had captured the moment.

very fast don't mean no shutter lag lah. slrs/dslrs generally have insignificant shutter lags vs film compacts or consumer/prosumer digital cameras.

that said, you have gotten nice shots. I like the seond one taken with ambient lighting

Sorry, what do you mean by manual flash? How then do you determine how much flash to use to achieve correct exposure?

I also notice Drudkh's exif info says flash at 1/2 power. What does it mean? Is it a manual setting on the flash unit itself? I don't own a 5600, but a D7 and it controls flash by exp, just like bracketing, rather than by power.

Thanks in advance.

In manual flash, you preset the power of the flash to fire. You can use the guide number/aperture factored with ISO to get the flash distance. The flash when in manual mode will have a flash distance read out to aid in calculations.

1/2 power means the manual flash ratio is set at 1/2. Guide number is halved. There are also different guide number for different focal lengths.

For bounce, it usually you would need alot more power, harder to use if you do not have digital.

Manual flash ratio is only available in KM top of the line flashes. D7D built in flash can set manual flash ratio but not in D7.

Cheers!

Thank you for the explanation.

If u shut off ADI and use just TTL, wouldn't that also give u "instantaneous" shutter trip? There isn't any calculation to do on the part of the camera. Just to trip the flash and shut it off when the exposure is complete....

7D does not have TTL flash metering. It only has ADI, preflash and manual modes.

Cheers!

Flare · 3rd January 2005

And if i'm not wrong, no dslr has ttl mode, due to some technical limitations when dealing with ccd. So what's available is only preflash-TTL which is not the same as TTL...

TME · 3rd January 2005

Ah... yes! I forgot... hmm... ADI... if my lens is not D type then how? Pre-flash metering?

Preflash.
