OK... that's enough guys.
I'm seeing too much in the way of personal comments. If you can't keep the debate civil, take it somewhere else. This thread is now closed. Jim C. |

But, I've already warned you guys about keeping it civil. I don't usually give public warnings, and I've got a pretty thick skin. But, I'm not going to put up with those kinds of personal comments in our forums (including the ones you just made towards me). Consider this to be a warning, and if you like participating in the forums here, I'd take it seriously. Jim C. |

This thread is now reopened, even though I think this issue has been beaten to death.
Anyone willing to particpate in civilized discussion is welcome to do so. But, please keep any personal and inflammatory comments out of it. We have a friendly community here, and I'd like to see it stay that way. Thanks Jim C. |

Ok, let me ask this then....
My Sony H1 has a 6mm-72mm zoom which is 12x. The listed 35mm equivalent is 36mm-432mm. So if in the 35mm world a 50mm lens is considered the normal view or to put another way, 1x, would my H1's 50mm equivalent be 8.33mm (50/6)? If this is true, then 8.33mm to 72mm should be 8.64x. With my 7x binocular up to my left eye and the H1 EVF zoomed out to 72mm up to my right eye, looking at a object 1 city block away, the object appears a lot closer (not field of view) thru the 7x binoc's than the 8.64x H1. I add the 1.7x telephoto lens which should bring the magnification to 14.69x (8.33mm-122.4mm) and the 7x binoc's still look closer, but the H1 EVF view w/Teledoes appearabout twice as large as without (which makes sense). So Question: What is the 1x mm (50mm equivalent) on the my H1? What is the x comparison to my binoc's at full zoom (72mm)? FWIW I did email Sony camera tech support with the above question and they said they did not have the answer and suggested that I call their support help line and talk to one of them. :-( tnx George55 |

George:
Ignore the x ratings you see for digital cameras. All they're doing is showing you the difference between the widest and longest zoom settings, and don't tell you anything about the angle of view you have. For example, a 5-50mm lens would be 10x. A 50-500mm would also be 10x. Yet, the focal length is 10 times as long in the second example. ;-) The reason your Sony's lens is referred to as a 12x lens is because 72/6 = 12. This doesn't have anything to do with angle of view, focal length, or apparent magnification. It's just a way to let users know how much difference there is between the widest and longest zoom settings Ignore it for purposes of angle of view/apparent magnification. |

Yes I understand that, that's why I'm asking my question. I'm trying to figure out what is the 1x position of my zoom, and from that point to the max telephoto position (72mm), how many times closer does the object appear? My binoculars are 7x35, so they make the object appear 7 times (7x) closer (larger?). How many times closer is the object when I'm zoomed to max (72mm) with my H1? tnx George55 |

You can work this out from the 35mm equivalents. The lens is quoted as 36 - 432. As you sat 50mm is roughly equivalent to the human eye's field of view so 432/50 gives 8.64 so that is the maginification as compared with the naked eye. As the conversion factor seems to be 6 then the actual focal length of the 'normal' field of viewwill be 8.3mm.
