Knocking background out of focus
Is it possible to put the foreground in focus and the background out of focus without a zoom and while using a non SLR? I'm thinking of buying a shockproof waterproof camera...
Thanks, Paul

What aperture setting does the camera have that you're thinking of buying?

Well I don't really know. Something from Olympus.

Something like this. http://www.ephotozine.com/article/olymp ... view-26861

I don't believe you'd be able perform that function with that particular camera. The maximum aperture is not large enough to get effective "selective focus" images (f2.0). With the small sensor in compact cameras, you'd be aiming to find someone around f0.5 or larger (an impossible task in a consumer camera.)
Small imaging sensors require (physically) very short lenses to achieve similar fields of view to those found in 35mm photography (which is the the standard when they say "equivalent length lens"). Such short lenses need extremely large apertures to achieve selective focus, even at what they call telephoto lengths. The makers of these compact cameras don't see it as an important function and do not fit the lenses that could achieve selective focus because the cost would be way too high. (Not to mention, the size of such lenses would push them out of the market.)
The optics of lenses pretty much demand a large camera system to achieve selective focus.

In the old vernacular of cameras, we used to set the F-Stop to low numbers, such as 1.2 or 1.8. On my cheap Sony Cyber Shot with 4X optical zoom, I go to ‘auto-focus’ and ‘change focus area’ then pick ‘specific focus area’. There may be similar settings on your camera.

Oh, and you'd also be searching for a camera with manual focus, or at the very least, locking focus that enables composition after selecting the focal point.

Hmm. Well waterproof is more important. Anything else will die in my hands. Is there anything around that will do both?
Thanks, Paul

Short of a full-frame dSLR in a dive housing, no.
You could simulate the effect in Photoshop, but I think you'd rather spend your time fishing.

My mobile is waterproof, and has defocusing of the background as a program in the camera app. Get a Sony z3
