Hi,
My friend wants to give DSLR (Canon 300D) a try. He worries that his film lens (EF) will not work or have problems on 300D. Did anyone have similar experience? The following also botheres me: " The 1.6x focal length multiplier means that the outer 40% (approx) of a standard EF lens is not used " thanks! |

The following also botheres me: " The 1.6x focal length multiplier means that the outer 40% (approx) of a standard EF lens is not used " thanks! The EF lenses work without any problem on my 300D. Basically, there is no film EF lens. On the other hand, there are digital EF lenses. The EF-S lenses will not work properly on a film camera becasue they coverage is smaller than a non EF-S lens. So any EF-S lens he'd buy will not fit his film camera. The 1.6x multiplier is not a problem but he will have to buy a new wide angle lens if he needs one. |

All of Canon's EF mount lenses work just fine on the RebelD. So do most of the aftermarket mfrs lenses, the only exception MAY be those older ones from Sigma. Since lenses generally soften out at the edges, not utilizing that part of the lens usually presents little problem. It's just when your 17-35 suddenly becomes a 28-60 that the 1.6x crop presents a problem... -- Skip Middleton http://www.shadowcatcherimagery.com |

The following also botheres me: " The 1.6x focal length multiplier means that the outer 40% (approx) of a standard EF lens is not used " The digital sensor is smaller than a piece of film. So? |

In article .com,

Here's a better way to think about it. The 300D is a smaller format than 35mm, so what constitutes "wide angle", "telephoto", and "standard" are different, just as if you'd gone from 645 to 35mm. For a 300D, the 35mm focal length is "standard", a 50mm is a short telephoto, and so on. |

You usually get best quality when using f8 or f11. A zoom lens that has a maximum aperture of 2.8 is big heavy and expensive. Using a wider imaging circle means building extra large so that the area that is covered is flat. The extra curve at the edge of a lense is what does them in. Aspherical lenses are a big deal. Using a sensor that requires less covering power than 35mm film is a boon. That is while digital lenses are cheap. They are basically lense designs that would be considered utterly **** by normal standards. |

As to the 1.6 multiplication factor, take a look through the archives of rec.photo.digital. -Joel ---------------------------------------------------------------------------- Please feed the 35mm lens/digicam databases: http://www.exc.com/photography ---------------------------------------------------------------------------- |
