The distance it will focus will depend upon the type of camera being used. It also depends upon which 300 mm lens you are using.
The Nikon 70 300mm is said to be the best compromise for its size, weight, range and quality of image in comparison to the Nikon 38 300mm. It contains close focus, 67mm filters and weighs at 745g. It doesn't need a tripod to focus, and features auto focus abilities, it contains the very best tele zoom lens. It is selling for around $587.
Well, one thing is focus. When you look at something far away, notice that anything close becomes blurry? And when you look at something close, that anything far away becomes blurry too. This is because your eyes are focusing, and that's basically what a camera does, is focus.
Canon is a company well known for not only its all-in-one printers but also for it's full line of cameras and camera equipment. The Canon EF75 300mm is a zoom lens.
A point and shoot camera can be a fixed focus which does not require focusing as in the single use types. If a camera is not auto focus or fixed focus then you must focus it manually. This is usually done by rotating a part of the lens until the picture is clear in the view viewfinder
who invented the auto focus camera
tell me the answer
The best way to think about the numbers is the higher the number the farther that lens can focus. So if you have a 210mm lens you can easily focus on an object that is very far away.
well,they focus like your eyes,when things are far,the lenses moves back and forth to adjust the clearness and blurness.<3vnh
The best way to focus the M417 camera is doing manual focus. Per the Amazon.com sales page for the camera, there has been noted that there is a defect with the auto focus. http://www.amazon.com/HP-Photosmart-M417-Digital-Optical/dp/B0007KTG1M
A CPU camera lens has electrical contacts on it. This means that it also has the auto focus option, which is where the lens will focus itself.
Apparently it an auto-focus camera. The user cannot focus manually. If you read the specifications (see related link) it has a full list of the camera's features.
