I understand that the smaller fstop the more DOF. I just want to relate this with preview DOF. I will try to see what is going on tonight with my DOF preview and will throw out more question if i do'nt understnad and see different. Peter Su, Doug, and Joe, thank you all of you for helping me Olivier >From: "Joseph Codispoti" <joecodi@clearsightusa.com> >Reply-To: leica-users@mejac.palo-alto.ca.us >To: <leica-users@mejac.palo-alto.ca.us> >Subject: [Leica] DEPTH OF FIELD PREVIEW >Date: Mon, 22 Apr 2002 11:04:03 -0700 > >From olivier nguyen <oliviertnguyen@hotmail.com> > > > > I don't uunderstand how to use DOF preview on my nikon FM2n. when i >press > > the lever for DOF, I see it deem down in my viewfinder. what is this >tell >me ? > > > > > >Oliver, > >In order to *see* the limits of depth of field, you need to train you eye >to >look for it. > >Try this: > >1) Find a suitable scene that will show depth of field easily such as a >long >picket fence. >2) Stand at an angle to the fence. >3) Set the lens at its maximum opening (choose a standard or medium tele >lens). >4) Focus on at a point on the fence about 10 feet away. >5) If you are at an angle to the fence you will notice that what you >focused >on, and very little else, is in focus. >6) Activate the preview feature and close the lens slowly observing the >change in depth of field.
