Press the shutter and take a photo for $100?

I have not had or used a P&S for years. I used an SLR back in the 70s and then had a 35mm P&S I liked and then went to a digital P&S. I had several and they all suffered from what I call shutter lag. You press the shutter and there is a very noticeable delay before the photo is taken. I lost a lot of shots and this is one of the major reasons I went to a Rebel XT and then a 40D. (Now waiting on the 7D Mk2.)

My wife is going to DC and NY for a week and I asked if she wanted to take the 40D. "No, no and no for many reasons, I'll use my phone". (Samsung Galaxy S 3).

I started looking on Amazon for P&S cameras for about $100.00 and in the reviews there are complaints about shutter lag and then the time delay between photos.

It seems that pressing the shutter and taking a photo is a basic function of a camera and I am amazed the various manufacturers haven't figured it out yet. Are these folks nuts or is this still an issue with P&S cameras?

Is there a point where Canon P&S, or any brand, does not have a delay between when the shutter button is pressed and the photo is taken? I think my wife would tolerate some delay between taking photos. Should I tell her to just use her phone?

Thanks for help and suggestions.

Tom

The issue is that, unlike your 40D, P&S cameras use the same sensor for AF and for image capture. This means that they have to rely on "contrast detection" autofocus, while the separate AF sensor on your 40D uses "phase detect" AF. And contrast detection is inherently slower than phase detection, never mind that the sensor has to shift between the two modes.

Thanks Jon. I never knew that was why P&S cameras had this problem. Seems like someone would have come up with a better focusing system by now to solve this problem.

There have been some improvements, but this is the same problem with all P&S cameras, all of the mirrorless cameras and with DSLRs when they use Live View or are in video mode. And it gets worse as the sensors get larger because of the narrower depth of field.

Is a P&S really slower than the S3? I would expect that any quality camera would be much better than the cell phone, if for no reason other than a larger lens.

I have the Canon SX150 and it's been great for me. Any lag there is is something I haven't really paid attention to. Unless your wife is traveling for a sporting event, or other fact action photo shoot, won't a P&S lag in shutter be adequate for site seeing?
I haven't used my P&S but once since I got my DSLR about a month ago but I don't believe my P&S was that slow.

In terms of speed too, if you purchase a P&S you might want to be sure to also get a good memory card with faster write speeds just to ensure there is no additional lag in writing data after the shot is captured.

there are solutions. just not at $100 and just not with canon. spend 4-10 times more and you can get cameras that will focus faster than your DSLR. some newer cameras are using both phase detection and contrast detection to help with focusing.

I would love to know what model(s). I have a Canon G11 and G12 and my only major complaint is the shutter lag which causes many missed shots for action/sports/people etc.

Even with manual focus and exposure, from half press, when I give it a full press there is noticeable lag, maybe .3 of a second or so. Fine for static shots but for anything moving or alive, I hate it.

I have had 35mm SLRs years ago (up to a Canon EOS 1N) and there was zero detectable lag. I don't want another SLR, I need something that will fit in a large jacket pocket so I actually carry it around sometimes, an SLR is fun for a while, but soon turns into a pain in the butt!

I go to the store and try out most new compact when they out (Canon, Nikon, Pentax and Sony compacts) but haven't found one that is noticeably better than my current Canons so don't buy.

What models should I be looking at?

Thanks,

Steve.

Well, I have the S3 and the camera is rather good, with no perceptible delay. AF is activated every time you point it at something new and there is SO much depth of field that you can't really mess up. I can understand why she'd want to just take that. I don't even use my own P&S cameras anymore because carrying them in addition to the S3 is just silly.

your 40D has a shutter lag of 0.15 sec. below is a link of some P&S camera shutter lags, some are as fast as your dslr some not

So I just ordered the Canon PowerShot A2300 from Amazon.com for $72.00 plus tax.

I gave up on the whole shutter lag issue and focused on price and size. My wife won't use this thing if it is too big/heavy for her to take around and I don't want her to worry about loosing or dropping it.

We will spend some time with the camera before she leaves and like I told her before I placed the order, "Lincoln ain't going to move".

When we are chasing the grandkids around I'll use the DSLR.

Thanks for all the replies and links. I can always count on POTN for an education.

It's a pity that table is so sparse. I looked but can't find a more comprehensive one anywhere.

Just prefocus and anticipate the shot. You will just have to spend more money with another camera company if you want faster AF and less shutter lag. Shutter lag is a common complaint of Canon powershot cameras whether its a lower end A series or a high end G series. All are slow to af and not the most responsive.

I don't really understand the whole shutter lag thing. I wish these cameras had "release priority" where they would release the shutter on full press regardless of focus. That would solve most problems.
