It depends on what you want to photograph, assuming you need this and not just "view" (that's what binoculars are for). I suggest a 200mm telephoto as a minimum, ideally 400mm. As price increases considerably, you can use an adaptor to increase focal length. A 2x adaptor will provide 400mm instead of 200mm, but you will lose on quality. Also, considering the distance, you will need a tripod to shoot steadily at such a distance. Some telephotos will have stabilization (VR, IS etc depending on manufacturer) but best results will be provided using a tripod.
Most lenses with a focal length of more than 200mm are commonly used for shooting sports and wildlife. A long telephoto lens -- in conjunction with a large aperture -- also has the side-effect of producing an exceptionally smooth background blur.
this is the number of millimeters a lens will make a sharp image at, usually from its back element. 50mm is usual on 35mm film cameras-i.e.as your eye sees a subject. Digital is different for each 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.
Any lens (other than those used exclusively for close up work) can focus on infinity, which is simply put, is the distant horizon. Whether or not you can make out the small detail is another matter.
probably a good $300 probably a good $300
Sigma has a 70-300 zoom lens that is comparible with the Nikon F55. It costs around $150.
It is not clear what is meant by Canon 70 300. There is a camera lens with a close name, which is known as a Canon EF 70-300 that is a telephoto zoom lens. It retails for approximately $700 and can be purchased from almost any online camera part store.

You can get a nice used zoom. I don't know the brand of your camera but Canon has a nice 75-300 zoom.
If the area of the parallelogram is 300 square yards then its height is 300/15 = 20 yards
300 yards = 274.32 metres
12 inches = 1 foot 3 feet = 1 yard 1 yard = 0.000568181818 miles 300 yards is equal to 300 yards = 0.1704545454 miles (300 yards x 0.000568181818) 300 yards = 900 feet (300 yards x 3) 300 yards = 10800 inches (900 feet x 12)
to convert yards into feet, multiply the yards by three. 300 x 3=900 300 yards=900 feet.
There are 3 feet in one yard. Therefore, 300 feet is equal to 300 / 3 = 100 yards.
300 feet=100 yards
300 kilometers=328,083.99 yards
300 meters = 328.1 Yards
