Filter Close-UPFilters to make your original lens to take pictures of the object. Close up This applies to all lenses Save money to buy a macro lens. With filters at very affordable. It can provide the macro equivalent of the real you."Filter Close-up lets you shoot close up how" ???A very good question But the same poser Conclude filters CU is typically labeled, such as +1, +2, +3, +4 or +10, +10, some of which may be referred to as macro filters. The name tells the ability to change the focal distance of the lens, it is when we put the lens CU +1. Will focus range of the lens. From before our filter lens can focus the eye from a distance or infinity to 55 cm when put CU + 1 lens can not focus at infinity, then. The lens range up our focus will change to 100 cm.. Until near the end of the work done at 50 cm, 30 cm, but it is does not mean that when we put filters already. We will not be able to rotate the lens focus ring of the lens to infinity me. We still do the same, but the distance to infinity object will not clear it. Is clear that the objects within 100 cm.. Instead of just me conclude this look like it here.
Add filters to the lens focal distance as far as the distance to infinity focus range after entering CU + 1 will change as far as 100 cm when put CU + 2 extreme focal length will change to 50 h. m. Enter CU + 3 Focus range will change as far as 33 cm put CU + 4 Focus range will change as far as 25 cm and put on CU + 10 will focus distance as far as 10 g. m., and the result will be like this with all the lenses empirically simple numbers tell directed at individual filters are meant to be the focal distance of the lens to change from + 1 means that far. Infinity Change (100/1) = 100 cm, CU + 2 represents the focal length telephoto end will change to (100/2) = 50 cm, CU +3 is (100/3) = 33 g. .m.
