Magnification and perspective are related, but obviously not the same. Magnification is simple enough to understand since it is magnifying a subject using more powerful lenses.
The maximum magnification (MM) of a lens is a description of how large an image it can project onto the camera's sensor compared to the subject's real-life size. It is given as either a ratio or a multiplication factor (e.g. 1:2 or 0.5x).
Lens magnifications are marked in millimeters (mm). For those new to photography these markings don't give a lot of help in deciding what lens they need. The following images will show you the difference between magnifications for the same subject.
Magnification Factor
If you use a digital camera with a less than full-frame sensor, to calculate the effective focal length of your wide angle lens you will have to multiply the focal length by 1.5x for Nikon, 1.
Magnification ratio
Ratio that express greatest possible on film magnifying power of the lens. Used commonly on the macro setting of the zoom lenses, macro lens or with bellows.
MAGNIFICATION
In addition, refraction causes a magnifying effect which makes subjects appear to be 1/3rd larger and therefore nearer. This only causes problems if you start to physically measure distances underwater.
Magnification ratio. A relationship that represents the amount of enlargement provided by the macro setting of the zoom lens, macro lens, or with other close-up devices.
Magnification of Objects Underwater
Since we are talking about water, I should note that objects can appear up to 25% closer underwater than they actually are.
Play magnification
Rotate the main dial counter-clockwise to magnify the currently displayed image, there are a range of magnifications available; 2.0x, 3.0x, 5.0x, 7.0x, 10x and 14x.
Magnification is essential when photographing wildlife for a number of reasons. The most obvious is it allows the subject to appear larger in the picture. Unless you’re creating an environmental portrait, bigger is usually better.
Magnification:
Is the size of the image relative to the size of the subject used to produce it. It is an expression of the ratio of the subject-lens distance to the image-lens distance.

Magnification can be specified in three equivalent ways, descriptive, magnification and ratio.
magnification. If you are shooting close-ups camera movement is magnified along with your subject.
Magnification of 1:1 (Coin 21mm CCD 23.6mm)
Magnification of 2:1 (Photographed zone 11.8mm CCD 23.8mm)

Magnification obtained by adding extension tubes to some commonly used lenses.
Magnification ratio
Commonly referred to compact size sensors in modern DSLR cameras. Also know as crop factor.
= Magnification
For example, it would take 100mm of extension on a lens with a 100mm focal length to achieve life size (one hundred divided by one hundred equals 1x).
At magnification 1:100 you have a smaller DOF than at 1:1000 and a bigger DOF than at 1:10. Stopping down to e.g. f/8 has a different effect on the DOF - it increases but in increases by a different degree.
The magnification power of lenses for DSLR cameras is noted in millimeters. This is also referred to as the "Focal Length". Have you ever heard the term "long lens"? This refers to a zoom or telephoto lens that has a long focal length.
At these magnifications, both images show some degradation due to the sharpening. However, the JPEG image shows much more degradation. This is particularly an issue when images are going to be enlarged significantly.
A digital magnification of the center 50% of an image. Digital zooms increase the apparent image size by interpolation. They do not increase the amount of image information.

Zoomy - E-Magnification
Zoomy is a quick and easy plugin that will zoom into a picture. You only need two copies of one image, first the display image and then thelarger zoom image.
This "Image magnification" factor gives us one more issue to consider when deciding if a DSLR will work for professional level landscape photography and large prints.
Viewfinder Magnification Magnification applied to the viewfinder is approximately 0.7X with a 50mm lens. This means objects in the viewfinder look 70% as big as they do with the naked eye.
Also known as Magnification Factor, this term is used to describe the angle of view of a lens used on a DSLR in terms of how it would appear on a full-frame 35mm camera.
Macro Magnifications illustrates how the magnification you get with a macro lens is usually specified as a ratio between the size of the image on the image sensor (not in an enlarged print) and the size of the subject.

The lens's native magnification will deliver life-size imaging, but getting great magnification will require some kind of accessory, such as a teleconverter, extension tube or diopter (close-up lens).
Eyepiece The lens system used in an optical instrument for magnification of the image formed by the objective. Eyepieces come in various types. Every eyepiece has a focal length.
Out on the tussock tops a 400mm lens would become the desired minimum To give you an idea of focal length compared to magnification, a 50mm lens is the rough equivalent to the normal eyesight perspective.
This magnification allows you to focus the actual grain structure of the image. A grain focuser provides you with the sharpest focus you can get from a given negative.
The combination of either a macro lens and the D70 camera offers you a magnification of 1.5X. A set of extension tubes will work with digital cameras and can extend your magnification well beyond the 2X range.
Output sharpening is best done when viewing images at a screen magnification of 50%, the screen magnification that best displays medium-frequency detail such as contours.
Focal Length Though technically focal length is focusing distance, when dealing with camera lenses, what this figure designates is the angle of view or magnification of the lens. The bigger the focal length, the more magnified the image.
No focusing for the subject is possible (or in sales talk, none is required), as the depth of field is assumed to be sufficient for anything other than a "close-up", at least for small magnifications.

1) Buy a true macro lens capable of reaching 1:1 magnification.
(see the previous section for an explanation of 1:1 magnification) This is the most expensive option, since true macro lenses aren't cheap.
For close-ups of the insect world, macro lenses which will give one-to-one magnification and show nature in its infinite detail.
By adjusting the focal length (manually or mechanically), the degree of magnification can be altered. This feature is particularly useful for picking out subjects at a distance. The zooming power of a camera can usually be read on its lens; 3x (e.g.
Focal length also determines the magnification, or zoom, when you look through the camera. In 35mm cameras, a 50mm lens gives a natural view of the subject. Increasing the focal length increases the magnification, and objects appear to get closer.
The result is increased magnification for close-up photography. They are sometimes also referred to as "extension rings".
Another benefit of teles is the inherent lack of depth of field that comes with high magnification.
1) When shopping for a telescope don't get to caught up in its magnification. While magnification is important it is not THE most important thing to consider.
Focal length determines both the magnification of and image, as well as the angle of view. Angle of view is the width of the image.
An excellent way to increase magnification without having to carry around the extra weight of another bulky lens is to purchase a teleconverter lens.
Because of its slightly thicker body, the magnification of the M9’s range/viewfinder is slightly lower than that of a standard Leica MP or M7 (0.68X vs. 0.75X). As a result its effective base length (EBL) is only 47.1mm.
Underwater Photos and Magnification
Above the water, the camera sees at the same level of magnification as your eyes. The same cannot be said for underwater photography.
Most macro photographic lenses have magnification ratios of 1:1 or 1:5. In 1:1 magnification ratio, the size of the subject in the image would be almost the same as in real life. Taking macro pictures can be done in a compact camera or in a DSLR.
A word coined by Benoit Mandelbrot in 1975 to describe shapes that are "self-similar" -- that is, shapes that look the same at different magnifications.
A real DSLR macro lens has the capability of achieving in the least a 1:1 magnification. This should be written either on the lens or in the manual under specifications. Note: the aperture f stop is not the ratio we are talking about here.
As opposed to optical zoom - which is a magnification of the image through changing the lens's focal length - the term digital zoom refers to cropping the central part of the frame to make up a new separate image.
Magnification is only partly a function of lens selection; it's also partly a function of sensor size.
Without the need for high magnification optics, the AMI can detect the slight variations in shape of fine patterns via brightness changes of the captured images.
If you don't have such a lens, SLR users can consider getting a set of close-up filters which attach to your lens like regular filters, but provide magnification that allows you to get very close to your subject.
A digital magnification of the centre 50% of an image. These give less than sharp images because the new zoomed image has been interpolated. Don't be swayed by the incredible 500% zooms on some cameras, the images won't be really acceptable.
In a strict sense, macro means that the subject being photographed is projected onto the image sensor at a lifesize scale, or 1:1 (one to one) magnification. Macro photography is close-up photography of usually very small objects.
Use lenses with no more than a 2X magnification for normal-sized photographs. You can use greater magnifications for smaller pictures. You can even dismantle a cheap pair of reading glasses for the lenses if you cannot find any other source.
