Viewfinders on DSLR's
In article , dosferatu says...
Just getting into looking at DSLR's. Looking thru, anyway. So DSLR's, I assume, don't have focusing screens? Is that why looking thru the viewfinder everything is in focus? Do any DSLR's have Depth of field preview thru the viewfinder or do you have to go to the lcd display? What is Depth of field preview ? -- Alfred Molon ------------------------------ Olympus 50X0, 8080, E3X0, E4X0, E5X0 and E3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

Press the DOF preview button and the aperture goes from wide open, as used for focusing and framing the shot, to your selected aperture. The VF will now 'preview' what's really in focus/not in focus at that aperture and focal length. The main problem is that it will get dark in the VF at small apertures. |

Oops... and there are DSLRs which cannot do this? I thought it's a basic feature of DSLRs that they will show you in the viewfinder what is in focus and what is not in focus. How else otherwise could you creatively compose the shot by choosing the right amount of background blur? I'm starting to think that the only DSLRs with a usable optical viewfinder are the expensive ones. The ones I might buy (Sony 350 or Pentax K20D) have pretty pathetic viewfinders. -- Alfred Molon ------------------------------ Olympus 50X0, 8080, E3X0, E4X0, E5X0 and E3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

When you can just look at the shot moments after taking on the LCD at the back, real-time DoF preview become slightly less useful so, yes, horror of horrors, it is omitted from some cameras. I compared the viewfinders of the DSLR brands I was considering when I bought my first one, and concluded that Nikon was slightly better than Canon in showing a bright image. They are both /way/ better than any compact camera I have used in terms of image quality, although they lack the "gain-up" feature of some compact cameras which can help for extreme night-time shots. Yes, if you pay more you may get a better viewfinder, but even that of the Nikon D40 is eminently usable. Try looking through the viewfinders for yourself. Cheers, David |

I remember briefly using a couple of years ago a Nikon D70. And wow, what a viewfinder. Recently I checked instead the Sony 350 and the Pentax K20D and was very unimpressed. It's good that these two cameras come with live preview, so you can use that for framing. -- Alfred Molon ------------------------------ Olympus 50X0, 8080, E3X0, E4X0, E5X0 and E3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

When you look through the viewfinder or on the LCD of a DSLR, the lens is wide open at its largest aperture. This allows the clearest and brightest view with the least depth of field for composing and focusing the picture. However, it does not show the actual depth of field that you are going to get, which can be critical. Most DSLRs have a button mounted by the lens which, if you press it, stops the lens down to the selected aperture. The viewfinder becomes darker because less light is entering the camera, but you can see what parts of the image will appear shop in the final shot. The depth of field preview button on my Nikon D300 does not work when Live View is turned on. -- Waddling Eagle World Famous Flight Instructor |

I have a d70 at work, and a d200 (own a d200 too). The D200 viewfinder is so much better than the D70s it isn't funny. The other photographer here has a K10D and says the same about its viewfinder, much better than the d70. Could be you were looking through an f2.8 lens on the D70 and an f5.6 on the Sony and Pentax, or was your lighting different. What is true is that the viewfinder on the d200 and d80 (same mirror box) are 95% viewfinders and the focusing screen isn't very textured making manual focusing a bit of a challenge, especially with wide angles. I use mostly macro/micro lenses on the cameras, focusing at 1:1 with the D200 is so much easier than with the d70. Tom Yeah, I have a D70, a D200, and a D300. The D70 has ceased functioning (probably a bad contact on a memory card pin), but the viewfinder of the D70 is both very dark and very small compared to that of the D200 or D300. -- Waddling Eagle World Famous Flight Instructor |

No idea what lens the D70 had. Still, the viewfinder of the D70 was quite impressive, while the ones of the A350 and the K20D were quite unimpressive. -- Alfred Molon ------------------------------ Olympus 50X0, 8080, E3X0, E4X0, E5X0 and E3 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

With that on, my K100D VF is a fair bit larger than a full frame Canon 5D VF. They are all rubbish though compared with an old Pentax KM film SLR I still have which is like going to the cinema compared with a TV. |
