After all, Panasonic seems to have given up the constant f/2.8 zoom in the FZ30. I suspect it is because they increased the size of the sensor (so the 8MP would have roughly the same pixel pitch and noise characteristics as the previous 5MP), and reused the Leica lens they had with the FZ20. -- Michael Meissner email: http://www.the-meissners.org |

If you peer at the pics of the FZ30 it's also 7.4-88.8mm rather than 6-72 on the 10 and 20. A very different piece of glass. pete -- "There's no room for enigmas in built-up areas" |

One of the major reasons I'm lusting after the FZ30. When you see a good shot coming up, the delay until the camera has readied itself can drive you NUTS!! -- Chas Right |

With the manual zoom and manual focus controls, VGA movies, and swivel viewfinder it looks like a true photographer's camera! Except for the plain hot shoe. No "TTL." You have to set things. No spontaneity. So one would have to keep their Nikon with external flash for those outdoor flash pictures, like Halloween parades. Don www.donwiss.com (e-mail link at home page bottom). |

While admitily my pictures became more spot on when I switched from auto flash to TTL, it isn't that hard to shoot with a generic auto flash once you get the hang of it. On my Olympus C-2100UZ, it was a matter of connect the flash, turn it on, and go into manual mode since the camera would remember the f/stop and shutter speed previously used, and if you only use manual mode for flash, the settings are the same as the last time. Of all of the steps, the one that took the longest was turning on the flash, and letting it cycle up. -- Michael Meissner email: http://www.the-meissners.org |

You leave the camera set at one f-stop, tell the flash that, and then the flash shuts itself off? At my Halloween parades people are all distances from me. Barely enough time for the camera to auto-focus. Don www.donwiss.com (e-mail link at home page bottom). |

Barely enough time for the camera to auto-focus. Yep. On an auto flash, the flash has a sensor that shuts off the light when it thinks the exposure level is at a certain level. On many flashes, there is a knob or dial that you set a given ISO value (usually 100). Then there is a color coded setting that says for green, use f/2, yellow use f/4, and for red use f/5.6 for instance. Different f/stops will give you different ranges (and will give you different depth of field, particularly on DSLRs). You set your camera to manual mode, setting that f/stop, and set the shutter speed either fast (such as 1/125 or 1/250) if you want most of the light to come from the flash (backgrounds that are far away will be dark due to light falloff), or you set it slower if you want more ambient light for the background (may have color differences between the flash and the background lighting). As you use it, you start getting a better handle of when you will need to adjust the f/stop up/down for different lighting situations. One area that you typically have to think about is zooming into take a picture of a person who isn't near a wall -- the flash won't receive enough light to know when to shut off the flash, and may wind up overexposing the subject if you fill the frame with the subject. This is an area TTL flash wins at without doing a manual adjustment. Many flashes also have a zoom setting that you can narrow down the angle of light (mine does, but I'm constantly forgetting to use it, except when I'm shooting at extreme ranges). A manual flash by way of comparison just dumps a fixed amount of light (for example, studio strobes do this), and you either use the rule about dividing the guide number by the distance to the subject to set the f/stop, you use a flash meter to measure the difference, or you just try different f/stops and chimp the results looking at the histogram to see what is the best exposure. In the old days, the wedding photographers would just get good at knowing how far a subject was by sight, and knowing what f/stop to use manually. -- Michael Meissner email: http://www.the-meissners.org |

This is an area TTL flash wins at without doing a manual adjustment. Which would be a problem in my Halloween parade pictures. Basically what this means is that if I were to buy an FZ30 I'd have to keep my Nikon 8400 with SB-800 to use for when I know I'd be taking flash pictures. This isn't a major problem. I have an 8400 as I like the wide angle. I don't like its lack of IS. I did see in the specs for the FZ30 a wide angle adapter listed. I'd like to find out more about it. But I can wait until after it becomes available. Thanks for the explanation. Don www.donwiss.com (e-mail link at home page bottom). |
