interchangeable lenses and my Olympus C-2100UZ
This is still about my Olympus c-2100uz. If anyone can figure out why I
cannot reply to a post I would dearly appreciate it. Now, I have several different lenses, filters etc for this camera. Are you saying that the lenses I have are not considered 'interchangeable'? If they aren't , would someone please tell me what an interchangeable lens is? Thank you for your patience. |

Ok here goes a I hope. An interchangeable lens means the lens dismounts completely from the Camera Body to be replaced by another with the same mounting. On the C2100Z you are using an ACCESSORY lens to compliment the FIXED lens on the camera body to give you some of the flexibility of the interchangeable lens cameras. It is a simple distinction often confused by ambiguous advertising. The basic lens on the C-2100 is NOT removable you can only ADD supplementary lenses to it. A dSLR on the other hand has a lens mount on the BODY of the Camera that permits the lens to be removed completely and replaced by another. Hope that helps. Dave F. |

So on the very early kodak digital cameras where there was a relay lens inside the camera to make better use of the early tiny sensors. Despite being based on, say, a nikon F90 camera, they weren't really interchangeable lens cameras? B |

B Interesting question, if it was simply a corrector in the light path INSIDE the Camera body but permitting the use of existing Nikon Mount Lenses I would tend to class it as interchangeable. I was trying to give a fairly simple answer in a gross manner not too tight on the fine points. It would Still be an SLR in any event since it used a movable flip up mirror and used the shooting lens as the view finder. Don't ya love how terms get mushy? Dave F. |

But it's an imaging lens with possibly multiple elements! I was trying to give a fairly simple answer in a gross manner not too tight on the fine points. It would Still be an SLR in any event since it used a movable flip up mirror and used the shooting lens as the view finder. Ah, so the pellicle mirror SLRs aren't really SLRs. Damn. Don't ya love how terms get mushy? Personally, I think the people who came up with these ridiculous group definitions should be taken out and beaten repeatedly about the head with a difficult-to-classify camera of your choice. Particularly the ones with the expensive point and shoot "ZLR" cameras and their raging insecurity issues. B |

On possible distinction is that if you change the lens on an SLR or DSLR you can actually get access to the sensor (or film), and hence changing the lens can let dust into the system and give you marks on all your subsequent pictures. The c-2100uz is a "sealed" system optically where this cannot happen - a plus point! Cheers, David |

On the other hand, if you're consideringthe c2100uz as a sealed system it shouldn't be possible for dust to get in between the primary and secondary lenses, but it is. B |

Yes, I was considering the sensor and any filter as a single unit which is susceptible to dust. Note the use of quotes around sealed! It's unlikely to be completely sealed as in vacuum-tight.
