Originally posted by lithedreamer A TA found an old K-mount Chinon with a f2.8/28mm lens on it. The camera was clearly cheap: it didn't even have a diopter on it and it has one of those weird split-screens. I...hated it. Everything was blurry. I felt so much relief getting back behind my K-30. The TA looked behind it and said that the screen looked fine to him, that's just how film SLRs look.
My K-30's diopter is set to the far right (as negative as possible). Are there things I should look for before going and buying a film SLR online now? This has left me nervous.
Perhaps the
old Chinon needed a good cleaning?
Do you really hate the weird split screen - where everything was blurry, after just one look and you don't know how to use it?
The TA made a very general statement that does not apply to all film SLRs. For instance the MZS has diopter adjustment as well as changeable screens like your K30. I am not familiar with either but since they are autofocus SLRs, likely
similar in view. However, there is one substantial difference and that is the K30 uses a sensor that is smaller than the 35mm film area in the MZS and therefore the scene presented in the viewfinder will be much larger when using equivalent field of view lenses. Viewfinder display is calculated by film/sensor size X magnification. For the K30 it is 0.92 X 23.7mm = 21.8 while the MZS magnification of 0.75 X 36 = 27.
In general, manual film camera viewfinders are much better than autofocus cameras since they don't have an autofocus system. For the same reason, manual focus lenses are also much better for manual focus use then autofocus lenses. The Pentax LX was the pinnacle of viewfinder development and has the most extensive selection of viewfinders and screens then any other camera regardless of brand or model - film or digital. Some of it's viewfinders have built-in diopter adjustment too. I included magnification and diopter ranges with each of the LX viewfinders.
With most manual focus cameras, you will have to select one based on having more eye-relief (smaller magnification) or less eye-relief (larger magnification). Generally, people who wear glasses prefer more eye-relief then magnification. With the LX, you have the option of having more eye-relief or a selection of magnifications from 1.35 down to 0.55. The smallest LX magnification (speedfinder FB1+ FC1) is closer to the view of the K30 at 0.55 X 36 = 19.8 as opposed to the FA-1 of 0.90 X 36 = 32.4. Since I don't wear glasses (yet!) I can see the huge difference between my LX and my K20D.
For fixed viewfinders, the MX has the largest viewfinder magnification of 0.97 X 36 = 34.9.
