To this day, many companies use a spring loaded mirror which, when released, simply slaps into a small piece of foam rubber for dampening. That indeed introduces a fair amount of vibrations. These are of no consequence with everyday photography. But high magnification photos, as in close ups and long telephoto work is definitely influenced by that. Leica solved this problem with the introduction of the original Leicaflex by incorporating a cam drive for the mirror. The mirror movement was activated by a cam that initially accelerated the mirror but then slowed it down to the point that it settled with virtually no movement at its uppermost position. That very much eliminated any vibrations. There is a simple vibration teat one can conduct. Set the camera on a level surface and then place a nickel on the camera sitting on its edge. Place it as close to the prism housing as possible because that is closest to the mirror. Then release the camera with a cable or electronic release. The majority of SLR/DSLR cameras will have enough vibrations to tip the nickel off its edge.LEICA Barnack Berek Bloghttps://www.blogger.com/profile/09055435560407011075noreply@blogger.comtag:blogger.com,1999:blog-1320126156594375642.post-35085718853199371412014-11-14T12:43:50.202-06:002014-11-14T12:43:50.202-06:00Conventional flip up and down mirrors in SLR and D...Conventional flip up and down mirrors in SLR and DSLR cameras have proven to be quite reliable.

But it seems too much of a price to pay for little, if any, gain. After all, other autofocus systems seem not to have any problems, so why give up viewfinder brightness and lens speed?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1320126156594375642.post-1942532623349477672014-11-14T12:39:33.541-06:002014-11-14T12:39:33.541-06:00Reader Ketil Are Haugsand wrote: - remembering th...Reader Ketil Are Haugsand wrote: - remembering the Pellix well - with the noisy clack (!) of any mirror in the sixties and seventies, we had great expectations, in principle.. but, agh.. how fast it disappeared! <br />Dark viewfinder and reduced speed - well, exactly!LEICA Barnack Berek Bloghttps://www.blogger.com/profile/09055435560407011075noreply@blogger.com
