The 1/23" sensor size's strength is in superzoom capability, not in image quality. If you are looking for a landscape focal length, this type of camera/sensor is a poor choice. Traditional APS-C or FF equivalent sensors will completely blow away this type of camera in image quality, ISO performance, dynamic range, RAW compatibility, light gathering, among ...


I've found this document it might be helpful for some of you who are learning how to design with Code V . Still searching for a tutorial on bi-ocular system design with Code V (a simple one). thank you for your help!


They are referring to the amount of clearance between the lens rear element and the sensor. The C mount flange focal distance is 17.52mm so both of these lenses have rear elements that stick into the camera body. This fact is most relevant to SLR cameras that have a mirror which moves out of the way when a photo is taken, a lens that sticks into the camera ...


From what I know back focal length depend of the optical construction of the lens. And it is important for mirror cameras. For example you can't mount EF-S lens on fullframe camera because last element will interfere with the mirror (which is bigger than APC cameras). P.S. Above abbreviations and explanation are related to Canon cameras and lens, but IMHO ...


The biggest factor that I can think of is cost and complexity around the lens design. Lens focal lengths that are shorter than the distance from the lens mount to the sensor (flange-focal distance) need to be designed with what amounts to reverse telephoto (retrofocus) lens at the end in order to make up the distance and the complexity level of that gets ...
