But not all of these macro lenses are equal. This brings us back to the minimum focusing distance of each of these macro lenses.

It can filter a beam of light of undefined or mixed polarization into a beam of well-defined polarization, known as polarized light. ... Thin film polarizers.

I talk more about macro photography, minimum focusing distances and reproduction ratios in this post about capturing macro images outside your front door.

The field of view is influenced by factors such as the focal length of the lens, the sensor size, and the distance between the lens and the subject. It plays a crucial role in determining how much of the surrounding environment will be visible in the final image or video.

Check out this video which quickly illustrates reproduction ratio and the advantage that smaller sensors have when it comes to reproduction ratio.

The 60mm macro lens is a small lightweight lens that is relatively inexpensive. On a crop sensor camera, the 60mm lens is like a 90mm lens which is a nice portrait focal length. Also, I use the 60mm lens along with the Nikon ES-2 Film Digitizing Adaptor Set to digitize images I capture with my film cameras like the Nikon F6.

We will calculate the HFOV(horizontal field of view), VFOV(vertical field of view), and DFOV(diagonal field of view) of the imaging system.

The 200mm lens gives your the greatest working distance from your subject and is excellent for capturing images of subjects that might move away when you get close.

Let’s look at a closeup of the head of the butterfly. The head captured with the 60mm lens looks slightly wider than the head captured with the 200mm lens. Just like when I am capturing a portrait of a person, the a longer focal length will compress the features while the shorter focal lengths will widen the features. There is nothing bad about the head of the butterfly captured with a 60mm lens. Just be aware that there is a slight difference.

Macro lenses have a reproduction ratio of 1:1. This means that the object is the same size on the camera’s sensor as it is in real life. A macro lens allows you to get close and capture close up images.

Look at the two images below. The one on the left was captured with the 60mm lens and the one on the right was captured with the 200mm lens. Look closely at the size of the wing on the right side of the frame. The wing is larger in the image captured with the 200mm lens. Also, the individual patterns on the wing are also larger in the image captured with the 200mm lens.

Note:1. Due to the complexity of the optical system, the following calculated values ​​are approximate and may differ from the actual effect.2. When the size of the object is large enough, you may need a wide-angle lens. The larger the angle, the greater the distortion effect.

This calculator is applied for calculating the maximum field of view (in length units) that an imaging system can capture under specific conditions using the sensor’s physical size (including horizontal, vertical, and diagonal dimensions), Working Distance (lens end to object end), and Lens EFL (effective focal length of the lens).

I realize that the Nikon 200mm macro lens is an older lens, but it is a fantastic lens if you are really serious about macro photography. The minimum focusing distance is really what makes it so great. It is my go to lens for skittish subjects like dragonflies.

This calculator is used to calculate the FOV(field of view) of an optical imaging system with given parameters. In this section, you need to fill in the Number of Horizontal Pixels, the Number of Vertical Pixels, the Pixel Size(μm) of the sensor, and the Lens EFL(effective focal length).

Most camera bodies have a symbol of a circle with a line through it to show where the camera’s sensor is located. The minimum focusing distance is measured from this line to the subject.

All three of my macro lenses have different minimum focusing distances. The minimum focusing distance of a Nikon 60mm macro is 18.5cm. The Nikon 105mm minimum focusing distance is 31.4cm and the 200mm macro is 48.8cm. These all seem like workable distances. However, the minimum focusing distance of a lens is NOT the distance from the front of the lens to the subject like some people might think.

Note:1. To accurately calculate the sensor’s physical size, you need to enter the Number of Horizontal Pixels, Number of Vertical Pixels, and Pixel Size (in microns).2. Some ultra-wide-angle lenses own a field of view of more than 180°, in which case the field of view range will be infinite (for example, when the lens focal length is very small and the sensor size is relatively small)3.Due to the complexity of the optical system, the following calculated values ​​are approximate and may differ from the actual effect.

The Nikon 105mm macro lens is a legendary macro lens. It is a great focal length and I use it for macro images and portraits. It has Vibration Reduction (VR) and a fast Silent Wave Motor (SWM). One of the things I like about the 105mm macro compared to the 105mm F1.4 when it comes to portraits is that I can get really close to my subject. The minimum focusing distance of the 105mm F1.4 is 1 meter so I am sometimes further away than I want to be. If I could only have one macro lens, it would be the 105mm macro.

The following video further explains the ideas of how the minimum focusing distances and focal lengths of different lenses affect your macro photography.

In the context of cameras and photography, the field of view refers to the area that the camera’s lens can capture in a single frame. A wider field of view captures more of the scene, while a narrower field of view focuses on a smaller portion of the scene. It is an important consideration in choosing lenses and camera systems, as it directly influences what will be included in the photograph or video.

The FOV(Field of View) is a measure used in optics and imaging to describe the extent of the observable world that can be seen at any given moment through a lens or optical system. The field of view is typically expressed in degrees and includes HFOV(Horizontal Field of View), VFOV(Vertical Field of View), and DFOV(Diagonal Field of View).

This calculator calculates the minimum FOV required for imaging by using the Working Distance (the distance from the lens to the object) and the actual size of the object (including the Horizontal Size and Vertical Sizes of the object).

There are lots of different macro lenses that have a 1:1 reproduction ratio. All three of my macro lenses (60mm, 105mm and 200mm) can capture images with a 1:1 reproduction ratio. See the images below from each lens.

When the 60mm lens is focused at its minimum focusing distance, the front of the lens is less than 4 cm away from the the subject! This might be ok for some things but it definitely makes it harder to approach insects or other living subjects. You are so close to your subject that you might cast a shadow on your subject and you can’t use your lens hood.

These Lens FOV(Field of View) Calculators are able to calculate multiple optical parameters in multiple dimensions to help you evaluate different optical imaging needs. The calculator currently includes three parts:

The other thing to take into account with these different lenses is the focal length. The longer the focal length of a lens, the more compression you will have in your image. When I use a 200mm lens, objects in the background will appear larger than when I use the 60mm lens.

If you need to get more detailed information about Lens Selection and Lens parameters, please refer to the Lens Selection Guide page.

The minimum focusing distance of a lens is the shortest or smallest distance that you can be from your subject and still have your subject in focus. The minimum focusing distance (also called the closest focusing distance) of a lens varies from lens to lens. Lenses also have a maximum reproduction ratio which is the ratio of the size of the subject on you camera’s sensor compared to how big it is in real life. A lens that has a reproduction ratio of 1:4 means that however big something is in real life, it will be 1/4 the size on your camera’s sensor.
