Hello dpc'ers.
One of the things I like so much about shooting with a DSLR is the instant shutter action when the release is presssed.
I wonder why P&S cameras suffer so much form shutter lag. One would expect manufacturers to be able to apply the same technology ?
Are there any truely lagless P&S cameras out there ?

The focus is WAY slower than with a dSLR. My shutter lag gets real low when I set it on single-focus (rather than continuous) and hold the shutter button halfway down: from that position I have essentially no lag, but I also can't cope with a subject moving into or out of the field of focus. Beyond shutter lag, I don't know what other factors imapct here.
Robt.

not sure, but what i am sure of is that after touching a dslr i'll never go back to shooting p&s. lol well maybe i'll do a few more challenges with my olympus p/s just to see if i can get the top score for my camera but im gonna wait on that.

| Maybe the only non-dSLR way to get no lag is to find an ultra-cheap camera with a fixed-focus lens, so there's no auto-focus to worry about; kind of the digital version of an Insta-Matic. Kids camera (I think including one which is waterproof to six feet or something) should run about $30-60. |

| i could be wrong, but doesn't "shutter lag" refer to the time between hitting the release and when the picture is actually taken when the lens is already focused? |

This is a very over generalised question/rant!
For a start to say that the focus on a P&S is way worse than a DSLR is very hard to quantify. It totally depends on the cameras and lenses used.
For instance, stick a non-USM Sigma lens on a 10D and it'll would probably be creamed by an Canon S2 IS.
I think you might need to take a look at some new high-end P&S cameras and have a play. Shutter delay has been improved considerably recently and is almost negligible now.
Would you really get frustrated with Canon's less than 0.1sec or Casio QU-R3 0.01 seconds? Would you have time? |

0.1 secs is pretty good if that's a non-SLR.
0.01 secs is very good even for an SLR. I believe my 1D has shutter lag in the tens/hundreds of millseconds. 10 ms is very quick! Is that the entire time for pressing the shutter button to taking the pic, though?

Use a pro camera, (Canon 1D, 1d mkII, Nikon D1H, D2H, etc) and tell me that..

No, I suspect those two figures are from half to full press.
I think you'll find I chose my words carefully. I said "almost negligible" to avoid backlash! I do use pro cameras quite frequently and I realise that the lag on them IS negligible.
My main point is that if you're the kind of photographer who needs to capture time-critical images and 0.01 seconds really won't cut the cheese then what are you doing buying a P&S anyway?
I think 0.1 sec is more than enough for most and it's getting quicker all the time with the development of DIGIC II and USM etc. Once you've got start-up down to 0.5secs and shutter lag to 0.1 (from nothing to full!) I think most P&S users should be happy.
These things are always a balance between cost, size, quality and performance and the new breed of P&S cameras are pretty flippin nifty.

I believe the Ricoh Capilo is the camera you are looking for.
Half press to shutter time is(according to an Aust. Magazine Better Photography) 0.003s.
Even if it needs to do the focus thing, the delay is only 0.06s.
I have not yet tried out this camera - but I did have a go at the previous model and it really did seem to do what it said....
Another little thing - often cameras with a view finder and an LCD will be MUCH faster if the LCD is turned off. For example the shutter time from half press for the Canon A95 with the LCD is about 0.8s with the view finder it is 0.08.....(from dpreview) try it out - it works!!!

Yup turn off the LCD to speed things up.
Still trying to understand if we are talking about shutter lag or EVF Lag which pertains to both View Finder and LCD.
My Canon PowerShot Pro1 never had an issue with Shutter Lag but the time it took to "Draw" the shot on the display (EFV or LCD) after focus lock and before actual shooting of the shot (full trigger release) was frustrating. The subject had already moved several feet. Canon put out a firmware update to cut the EVF lag in half but the delay will never go away as the picture has to be drawn somewhere before you can shoot the shot.
I love my PS Pro1 but don't go back to it often anymore because when you look "through the lens" of a dSLR what you see is what you get. When shooting a P&Ser you often have to do popcorn or shootgun shooting (spray and pray) to get those action shots at events like airshows...or you can try to get that one perfect shot (one shot per pass of the plane(s)...
For P&Sers... Turn display off, never use Continual AF as bear pointed and use the biggest buckshot you can find. Oh yeah and just bear with those dark screens between shots as that is part of the deal.

Both my 8800 and Sony P8 have manual focus, which obviously improves shutter lag considerably but requires much learning.
If I'm outdoors, shooting 8mp, 1600x1200, the 8800 is almost comparable to dSLR speed, barring any severe focus or lighting changes. I've been able to shoot continuously in direct sunlight.
But other than in those conditions, the speed degrades quickly and just takes experience to know how to get the shot (yes, great shots are still possible).
I doubt P&S will ever touch SLR, mostly because of the mechanics involved. I recently read a pretty good tech summary on shutter lag in a dig photo book - I'll scan and post some of it here. |
