720 mm
This is a Zoom lens with a focal length of between 75 and 300 mm.
I'm not sure I understand your question. If I do, the conversion from focal length of a digital camera to an equivalent 35mm focal length varies based on the cameras sensor size. These sizes vary by camera model. For most Digital SLRs you multiply the camera's focal length by about 1.6, but the multiplier ranges from 1.5 to 2. The multiplier for simple/consumer non-DSLR cameras is somewhere around 4 times.
Yes, when using a 35mm format film, the 50mm prime lens is considered a "normal" or "natural view" lens. This does not hold true when using a Digital SLR camera (DSLR) because the sensor for most cameras is not 35mm size (36 by 24mm). Entry level and enthusiast level DSLRs often have sensors that are about half size (18 mm wide) and therefore the 50mm lens is equivalent to a slight zoom. A 35mm or 28mm prime lens is closer to that natural view. Some of the more expensive DSLR cameras have a full size sensor and thus have the same magnification and characteristics of the 35mm film camera.
The shortest zoom that would be really useful for wildlife photography is a 300 mm, but a good lens to start off with is a 75 to 300 mm zoom, or a 100 to 300 mm zoom. Probably, the best lens to go with would be a 400 mm f5.6 lens for wildlife photography, because more than likely, a 300 will be too short. You should also buy a good, sturdy tripod. Make sure it's not too heavy for you to carry around.
The answer is in your question. They need smaller sensors to fit in smaller and smaller cameras. The full size DSLR camera has sensor as big as the old 35 mm film. Most compact camera have sensors the size of you fingernail or smaller.
no!
18 mm is the wide angle focal length and 200 mm is the telephoto limit of the zoom. for more info searching on focal length and field of view will give you lots of info.
I believe the camera is digital and doesn't take film. Cannon also has a good website that does have manuals you can download .
The term hyperzoom or superzoom is used to advertise photographic zoom lenses with unconventionally large focal length factors, typically more than 4× and ranging up to 15×, e.g., 35 mm to 350 mm. The largest ratio for digital SLR cameras is held by the Tamron 18-270 mm, giving 15×. Some compact digital cameras have even larger zoom ratios up to 35×. For movie and television use, Panavision holds the record with their 300X HD LensDSLR is digital single-lens reflex cameras
Turn the camera over. At the right is a small cover with an indent just beside where the strap is fastened. If you look into the indent you will see BATT in the plastic. Pry this cover open and there is the battery. It is a Lithium CR123 as shown on the inside of that cover.
That number is the focal length of the camera's lens ... which focuses light from the scene to form an image on the 'film' or CCD inside the camera. The longer the focal length of the lens, the larger (nearer) the objects appear to be in the picture. (One radian of angle as seen by the lens ===> One focal length on the film.) On the cameras described in the question, the focal length is given as a range ... "from 18 to 200 mm", and "from 55 to 200 mm". Each of these is a "zoom" lens, whose focal length can be changed over the range, enabling the user to cause objects in the picture to appear somewhat nearer or farther away.
It depends on what you intend on using your camera for. Landscape? Macro? or Portraits? For example. Landscape: Smaller mms Macro: Larger mm. Portraits: 70-18mm, that's what I have for my Sony DSLR and I'm sure it applies to most cameras aswell.
