I'm having a heck of a time getting my shots in focus.

Using the lcd screen on my Canon is a bear for someone w/ tri-focals.

Anyone have a tip for dealing w/ this?

This was the best camera I could afford so I'm gonna have to live with it for quite a while.

Thanks,

I have a problem with focus when I'm trying to do closeups in bright light. What looks good on the LCD doesn't always look good on the computer.

Having said that I've tried a couple of things, 1) use maximum depth of field and 2) use manual focus with bracketing turned on.

Also, sometimes it takes a second for the camera to get a focus lock. This means waiting for the exposure info to show up on the LCD before you press the shutter all the way.

the g3's an awesome camera and shouldnt have a problem focussing.

maybe your unit is defunct?

but here are some things to try --

1) use a tripod.

2) turn on a very bright light to get your auto focus locked. then , once focus is locked, switch to manual focus so it won't change. then turn your light back to what you need for the shot.

hope some of these suggestions are helpful to you ..

As posted by Mag, first try to determine if shake or poor light are contributing.
If you have problems at high shutter speeds in good light, however, then do check if something is not right with the camera.
With regard to vision correction and viewing the LCD, it is possible that you might be helped with some of the LCD shades with built-in magnification that are on the market. They are relatively cheap, but I don't know if they would work in your particular situation

I have problems with focus with digital cameras as well. In my case that is for one primary reason:

Digital camera focusing through the lense sucks!

Most SLR cameras have much better optics and focusing systems than digital cameras. That is because manufacturers of digital cameras think that autofocus will take care of everything. It does not. Therefore they do not supply granulated focusing prisms in their optices like SLRs do (did?).

In SLRs if the prism is focused then the image is. That is plainly visible through the lense even at exceptionaly fine focus. With digital cameras the LCD display can look perfect but the focus is way off when you get it back on your computer. That ticks me off.

Depending on settings your digital might have background focused and your primary subject out of focus. I hate when that happens.

The way around that is to take lots of images being mindful of that, used crosshair focusing if you camera has it and hope for the best.

That happens with my Canon G1. One thing you can try is to review the photo afterwards and zoom into it on the LCD screen. That gives a somewhat better idea of whether your picture was focussed.

As you say, that's the disadvantage of not having SLR. If it weren't for the convenience of digital, I'd be tempted to buy a film SLR.

Thank you to all..

I do use a tripod,, and feel I have my lighting isn't the problem.

I'm practicing w/ the focus bracketing aspects of the camera.
I've used that technique w/ film cameras, but in small increments to fine tune.

Now I'm discovering it's necessary to do so w/ a wider range to compensate for my lack of ability to "see" the focus on the lcd. very frustrating.

I'll check out the shade options... hadn't thought of that one. I'm also trying to figure out how to use a magnifer of some sort to be able to see the screen better.

It's hell to get old!!!
