Depends on the camera. The magnification of the *ist-D viewfinder is the same as that of my MX, and it appears equally bright (just cropped to a smaller image area, of course). On my MZ-S, with a lower viewfinder magnification (there has to be somewhere to stick the extra in-viewfinder information) the image is brighter. But I never heard anybody say they preferred the MZ-S viewfinder to that of the MX. The entry model DSLRs from some other vendors have a significantly lower magnfication, as well as the cropped image area, leading to an effect which has been likened to looking down a tunnel. There has to be a trade-off between brightness and overall image size, and I have no problems with the *ist-D, even using a lens with a maximum aperture of f/4. Of course it's not as bright as using a f/1.4 lens, but my old eyes can adapt to the loss of around a stop of light far better than they can perceive detail in a smaller image. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
