Are there any other 18x optical digital zoom cameras on the market other
than the Olympus SP550UZ? JB |

dev/null says... The Olympus SP 550 UZ only has 10X magnification, with a 18:1 zoom ratio. Who cares about magnification. The zoom is 18x. Besides, who would buy a camera whose widest zoom is 50mm ??? -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E300, E330, E400 and E500 forum at http://tech.groups.yahoo.com/group/MyOlympus/ http://myolympus.org/ photo sharing site |

The Olympus SP 550 UZ only has 10X magnification, with a 18:1 zoom ratio. It may end if you stop posting. Saying that it has only 10x magnification is nonsense. If you read all of the previous posts carefully you'll note that magnification wasn't even mentioned, only that the SP550UZ has an 18x optical zoom. With its 28mm - 504mm focal length range you have a lens whose zoom range is exactly 18x. Your personal "normal" base of 50mm isn't even generally agreed upon. Many photographers consider a normal lens to be a bit wider, somewhere in the 40mm to 45mm range. Using 40mm would change your assessment of the SP550UZ's magnification from 10x to 12.6x. For Olympus (or any manufacturer) to make an 18x lens that you'd accept it would have to be 50mm - 900mm, a real beast, and much less desirable for most photographers than 28mm to 504mm which adds a very useful wide angle capability. BTW, for the OP . . . Although it's only 15x and has a few shortcomings, Samsung's Pro815 is probably a much more capable camera, also goes down to 28mm on the wide end of the zoom range, (28mm-420mm) and has dropped enough in price to be selling for about the same amount as the SP550UZ. The Pro815's sensor is much larger than the 550's (good) but the camera is also much larger (bad). http://www.dpreview.com/reviews/samsungpro815/ |

Note: the digital part of a camera's zoom can be duplicated with far more flexibility in a computer using software than it can be in the camera. In fact you can digitally zoom far more after the exposure in the computer using a camera without any digital zoom than you can with any camera with digital zoom. I would suggest ignoring the digital part of any camera's zoom. -- Joseph Meehan Dia 's Muire duit |

With 18x optical zoom, the camera really should have IS or you'll end up
carrying a tripod. In my experience, you can make up for lack of a tripod by bracing the camera against any hard immobile object. I used to do this a lot to take 1 second night shots, and that was before digital viewfinders made it easier to frame the picture. -Joel ---------------------------------------------------------------------------- Free Bible and Mishna printouts in Hebrew: http://liturgy.lashon.net/ ---------------------------------------------------------------------------- |

But what I really want to comment on is the arguments about the term "magnification". In optical terminology the term magnification means the size of the image compared to the size of the object. Unless you are doing macro work, the image is always much SMALLER than the object. That is, the magnification is MUCH LESS THAN ONE (unity). An 18X magnification would not even be macro photography, it would be microscope photography! You are getting good if you even get a 1.0 magnification (my macro lens set does not get this far). As others point out, the (N)X stands for the ratio of the longest focal length to the shortest focal length. Because of the different sizes of image formats in digital camera, the actual focal length is not the best measure of the telephoto effect. Field angle would be better, but most of us are not really familiar with this angle in photography. I think the 35mm equivalent focal length is probably the best and most familiar method of looking at the actual effect of a telephoto/zoom lens. |
