something strange,

i took some photos on the weekend, most of which sucked very badly.

but out of the good ones was a sequence of a backloop.

strange thing is that the depth of field changes in each image. (which were taken in burst mode on aperture priority)

the first photo, background is blurred,
second photo background is not blurred foreground is blurred
third photo same as the first.
fourth photo same as the second.

in all photos the subject is in focus.

40d with 70-300mm ef-s is usm.

i don't get it?

You should have bought the Nikon.

But really, how can the foreground OR the background be out of focus keeping the subject, which is i assume in the middle, in focus? How close was the foreground/background? You'll need to upload an example, say shot #1 and #2.

Since it is on Aperture it is more likely that the camera has decided to change the focal point between shots. What was the focus program thingy on: Area, Point, Dynamic, Mutable, Drunk, I forget the names... you know what I'm talking about.

no offence but the fact that your saying you should have bought a Nikon shows that you know about as much about photography as Gestalt.

Gestalt,

My guess is you had the camera set to continuos focus. When your cam is on that setting it will need to do the following:

1) select a focus point (either 9 point selective or specific focus point)

2) focus on the object you are trying to photography and make sure the camera is locked on

3) assuming your camera locked on correctly it should now track the moving object automatically; this will not happen correctly if there is very little contrast difference between your object and the background; in that case the camera will start hunting for focus.

As I said this has 0 to do with the camera and everything to do with the operator.

However, you might find the following technique easier:

1) set your camera to single focus

2) set your focus point to either the center point or left or right most focus point

3) focus on the object and start shooting, after half a second re-focus and shot again

This takes some practice and won't work if you have a slow focusing lens.

So don't let anyone tell you, you should have bought a Nikon. As always, the camera is only as good as the photographer... not the other way around. The fact that there are so many bad photos on in the Gallery section proofs this...

For all you other poor bastards like me who can't afford a DSLR, with good quality lenses, this was taken with a Panasoninic FZ30 (cheap), full zoom 420mm, great P&S.

The sailer is Troppo at Yorkey's.
Nice coloured water hey, that's my speed strip




nice shoot... bummer about the huge depth of field and over sharpened image.

My Canon sucks!

Canons are for taking photos of butterflies and babies.

Of course I was taking the p1ss about the Canon.

That reminds me though on my Nikon there are 2 types of auto focus, one that sets and locks, another that attempts to track the object, I'm guessing your camera will have the same. You have to set this.

If in doubt check your manual
http://gdlp01.c-wss.com/gds/0900008236/EOS40D_HG_EN.pdf

Page 52 of your Manual talks about Sports mode (don't underestimate these auto modes. Select, take photo, got it - as opposed to fiddle fiddle fiddle, missed it)

Pages 76 -78 talk about setting the Auto Focus modes and selecting the auto focus point (although not the weighting, set to smallest, probably).

Too right, this type of camera can never compare to a good quality DSLR no way. I'd be a clown to say it could. Haircut's photos back on page 2 prove your point.

But I just posted the shot cos I'm happy with it and I know there are others reading here that might be thinking of getting a new camera but don't have the bucks to get into a DSLR.
I think a camera like this is great because it just sits in the car and if I get the urge after a sail to take some photos, It's just too easy to grab and shoot, no rooting arround
Don't worry if I had the money I'd have both in a flash

Cheers

shallow or deep DOF, nothing wrong with that pic imo Firey.B the gap between the superzooms and SLRs is forever shrinking

but will never be closed. Unless someone develops a new technology (eg water based lenses) I doubt "compact point and shoots" will ever match the quality of a DSL combined with a fast 500 or 600 mm lens. It's simply physically not possible to build a high quality lens system that small.

Of course a camera like mine will never match a quality DSLR, the other problem for a camera like the Panasonic is noise because the sensor is so small, but it's a good compromise for the dollars and the for the average punter

Sorry, I didn't want to hijack this thread, just been reading it and found it interesting and thought I'd show an alternative for people in my boat

hehe, i could see the joke panda was making. so no probs there.

the setup of the cam was as you described above. and i always focus then refocus. it was suggested to me that i may have drifted the camera off the action slightly in between shutter movements. so will concentrate on a steady hand more in the future.

i have no doubt it is me and not the camera. working on resolving that.

firie - i agree about the point and shoots being handy etc. i went away from them after seeing 2 p&s setups die due to the harsh elements. sand is a problem when it's blowing 20+ knots. that was a big motivator for me.

panda - the canon has 3 focus settings, still objects, moving objects, and camera select. i use servo (moving), also focus was set to centre point. unfortunately i was using a polarizer and forgot to set metering to average. the filters have gone in the bin for now.

cheers.
