    Hi all!
    I have just signed up to this forum and also just received my new Pentax K10D ... quite a hoot!

    Would anyone know where to find good, detailed information on DOF while using either a 28-200mm zoom lens and/or prime lenses ranging from 28 to 200mm?
    I also need visual samples of photos showing the different methods used and results thereof.
    Any help would be appreciated.
    Cheers to all.

    In general, depth of field doesn't depends on particular lens. It's just a matter of sensor size, aperture settings and focal lens.

    Try any DOF calculator that can be found online. E.g. http://www.dofmaster.com/dofjs.html

    Any ultrazoom lenses are pretty dim. I mean that they are usual F3.5-5.6. But if you need really shallow DOF you need use apertures like F/1.4 or F/2

    Thanks Vitali,
    Of course, that is true, any lens @F/1.4 or F2 would do a great job at shallow DOF.
    Also, thank you for the link, very useful.

    P.S.: I have ordered the new 18-250mm Pentax Da lens ... will let you all know how it performed.
