How to market 35mm quiet mirror invention
Hi, Folks--
A friend has invented and patented a mirror system which he believes will radically improve 35mm SLR camera noise and vibration problems. He's not very computer literate and has asked me for help marketing the thing over the Internet-- the miopic leading the blind, as it were. : I'm not a camera engineer but I think the SLR continues to have potential on into the digital realm and would sure wish the things to be quieter, so I'd like to see where he can go with this idea. Would greatly appreciate comments on the idea and some pointers as to how to go about this marketing stuff. Appropriate newsgroups, mailing lists, etc. to post announcements, comments on the website we've put together (http://www.quietcamera.com/), any other pointers or comments would be very welcome. Thanks-- Larry Miller La Paz, BCS Mexico |

: If the mirrors are split and slide as shown, there will be a point at which they join. The split would be annoying for users of the camera and appear as a dark line in the middle of the image in the viewfinder. There would need to me some serious dampening to stop the two sides crashing into each other (making noise) and leaving fragments of glass inside the camera. Since two pieces of glass have to move and hit the dampeners, I'd be surprised if the noise level is much less that an SLR. If a rubber strip was placed in the middle, it would block the user's view of the centre of the image even more. The split between the two pieces of glass would allow light in, which would severely effect the exposure sensors in the camera. I'm not the designer, will pass your comments on to him. : It will eliminate the LCD display-screen battery drain in digital SLR cameras. How? (The author's) statement *is* ambiguous. Uhh, I assume it's because one would not normally use an image display screen for a digital SLR? Thanks for the feedback-- Larry Regards, Aaron Queenan. |

its been done... *Totally* silent SLR mirror... ZERO noise because it
doesn't even move. Its called pellicle. Canon had it in the Pellix line of cameras in the 70's and up until a couple years ago in the 1nRS. But granted, it does loose a bit of light to the film.

Which is, I assume, the reason for its demise. Basic conceptual flaw, IMHO. Larry |

Bronica did a split mirror in the the 70's. The EC and ECTL i think. As long
as you knew which side to focus on you wrer fine. Dirk |
