Depth of field explained
The above is only the tip of the iceburg. here is my drop of water: DOF is a function of sensor size and f setting. The greater the sensor size the greater the FOV. The smaller the f setting (larger aperture) the less the depth of field (and more expensive the lens). |
Charles,
"Depth of field" actually refers to the depth in a scene in which objects appear in focus. More depth = more of the scene in focus. Because we use expensive accessories on video cameras to simulate the properties of a 35mm film camera, many seem to think that by adding these accessories we are getting "greater depth of field." In fact, using standard photographic terminology, a 35mm adapter gives LESS depth of field. Wider apertures also give less depth of field. Larger formats (film and chip size) give less depth of field at a given FOV and aperture. I think that a misunderstanding of the terminology is what causes so much confusion on this topic. |
Thanks Eric. I was about to take my own life. Good explanation.

FOV??? did I write that, Oops, way too long of a day...
Larger or more DOF with A SMALLER aperature, hince a pin hole camera needs no focusing and has an infinite DOF. Larger aperature gives less DOF and an infinitly expensive lens gives a... I don't know what you call an infinitly small DOF, hmm I will sleep on it... Thanks Eric |

Phil, at what time today do you think you'll post up the review on the EX3?
|
I would say midnight tomorrow night GMT
It's all ready...just need to click that publish button!! |
Awesome Phil, cant wait to read about it... Im sure its a fantastic camera, but from the look of the pics of the EX3, its taken a heavy dose of ugly pills... IMO...
:) Cheers |
Could somebody ( other than Philip who's sworn to secrecy) who saw the accidental sneak preview description of the EX-3 tell us what was in it. The article is gone for now.
|
I second Leonard! Whoever have read the article, is there anything way out different from the EX1? From the photos all I can see are the following changes: interchangeable lens / a monitor evf combination with an interesting mechanism / a revamped body with better placed buttons / some additional inputs and outputs / a very useful second accessory shoe placed in an interesting place.
I'm eager to know whether there is the facility to record SD like the 335 and 355's! |
yes, the big secret is that it's the new lens-less organic sensor technology. interesting stuff. could there ever have been a more anticipated moment on here than midnight tomorrow?

You have D1, D2, D3 1/2" Digital, D5 1/2" Component, D6 and so on, but no D4. |
From the little I've managed to dig up I'm guessing the secondary shoe is for a new 60 gig hard drive, redundancy or dumping? Both? Dunno.
