What lens would you use for a close-up?
Since making close-up shots falls in general photography, you do not need any special lens to do it. If your camera has an 85mm to 135mm range, it will be ideal for your close-ups. Most photographers believe that 85mm is the most ideal. In macro photography, however, you will need lenses that have longer focal lengths.
How do close-up lenses work?
In effect, a close-up lens is a high quality magnifying glass positioned in front of your existing lens. They work by decreasing the minimum focus of your lens. With a close-up lens fitted, you can move the camera lens closer to your subject and gain a higher level of magnification.
Do extension tubes increase magnification?
The extension tube serves to increase the distance between the lens and the sensor. This allows the lens to focus closer and, therefore, increase magnification, so you can use almost any lens for close-up photography. As with a macro lens, the longer the focal length, the greater the working distance you can achieve.
How do you find the minimum focus distance?
One peculiar point is that focus distances are measured from the sensor, not the front of the lens. This has one useful aspect in that the absolute minimum focal distance measured this way is 4 times the lens’s focal length plus the distance between the lens’s nodal points.
What is the magnification of a 600mm lens?
This characteristic results in a 1.5x equivalent magnification factor of your lens. A 600mm f/4 AF-S mounted with a Nikon D1h is a 900mm f/4 equivalent lens.
How much magnification do extension tubes give?
An extension tube increases lens magnification by an amount equal to the extension distance divided by the lens focal length. For example, adding a 25 mm extension tube to a 50 mm lens will give a magnification gain of 0.5X.
