I'l admit my theory's shaky, but isn't depth of field a function of aperture and focal length? Angle of view isn't directly relevant, being itself a function of focal length and size of sensor? -- Please use the corrected version of the address below for replies.

Yes but the so called standard angel of view will be archived on a much shorter lens on a camcorder or digital camera then on a 35 mm or bigger camera and shorter lens have greater depth of field. |

Mike Scott Harlow Essex England.(unet -a-t- scottsonline.org.uk) I know someone would say that, actually the DoF is more a function of aperture and magnification of the lens.[1] anyone who has used a 5x4 plate camera and a 35mm camera will know the difference.

| In message , SjT writes Snipped... I will look into ND Filters, i'm presuming you mean Neutral Density filters? I may pop into jessops and see if they can show me the difference when using them, From reading about them it seems they can sharpen up the image, sounds very interesting. You might be better advised to go for a polarising filter rather than an ND. Much more useful. For prices, search on Ebay for your lens thread size , e.g '30mm'. -- Tony Morgan http://www.camcord.info |
