Like I said at the start of this post, I really want to get excited about this one, but I also don’t want to set myself up for disappointment, again. It’s a problem, for sure, and one that many of the other projects failed to solve without attempting to physically alter the shutter of the camera (which defeats the purpose of an insert you can use with any camera). While my Nikkormats have a fairly substantial clunk, my N90s is also pretty quiet. I have a feeling that audible sensors will simply be too slow to react, especially with something more modern and quiet like the Nikon F100 or F6. I am looking into audible feedback from the sound of the shutter being engaged. This means, that something will be needed to trigger the digital sensor taking the photo. So the original shutter release button will be used to open the shutter still. I want the cartridge to fit in and out easily, with no mechanical changes needed to the camera. Shutter release button – This will probably be the biggest challenge. They don’t forget to mention the biggest hurdle, the shutter release button. I wouldn’t have much interest in a colour version, but black and white? Yes, please!
