Widest Aperture High Zoom Camera

The
Panasonic Lumix DMC-FZ150 with 24x zoom has the widest aperture at full zoom of all the super-zoom cameras we've seen.
Wide aperture lenses let in more light, but when the lens is at its
maximum focal length (aka its
maximum zoom) then the maximum aperture will be a lot
smaller (say f/5.6) compared to the maximum aperture aperture when the lens is at its
minimum focal
length (say f/2.8).
When you're zoomed in a lot you really need to have very short exposures to avoid blur caused from camera shake
- in todays superzooms offering 20X+ zoom any small movement of your hand creates giant movements in the image. In
order to ensure you can have short exposures you want to be able to shoot at as low an f-stop as possible.The
learning topic on
apertures explains why big apertures (the same as low f-stops) allow you to expose the image to more light.
Rule of thumb: The widest aperture at wideangle focal lengths
> widest aperture at telephoto focal lengths
