Some of the more common crop factors to be aware of that relate to specific camera manufacturer sensors include the following:

Whether using a converging lens or diverging lens, the focal lengths represent the distance from the optical center to the image plane in the camera.

Knowing the focal length of a given lens is essential for selecting the right lens and image distance for a particular shot.

Typically, this is indicated by a Φ symbol located on the top plate of the camera’s body, with different focal lengths used to accomplish different shots.

If you’re using a zoom lens, you can also find the range of your lens’s focal length on the zoom ring located in the middle of the barrel.

Though quarters are some of our largest coins, the diameter of a U.S. quarter is less than an inch. It measures 0.955 inches or 24.26 millimeters, to be exact. This makes it slightly larger than a nickel and dime but smaller than a half dollar.

At the same time, bear in mind that crop factor may be something to consider when working out the optical zoom capabilities of a given lens and sensor combination.

To do so, you’ll need to factor in the minimum and maximum focal length of the lens’s zoom capabilities in this simple equation:

Coins may seem like simple transactional objects, but they hold a wealth of information about our country's history and culture. They also make excellent visual tools for teaching kids about math and money.

If you’re using a zoom lens, the minimum and maximum focal distance should be printed on the barrel’s zoom ring, indicating your position between these focal lengths.

The equivalence of a 10x zoom in millimeters is dependent on the initial starting point and whether you’re using a crop or full-frame camera.

A larger zoom lens with a coverage of 18 – 200mm would have a larger optical zoom coverage, with the equation revealing this as an 11x optical zoom.

We don't spend much time thinking about coins these days, but they are a fascinating source of history and trivia about our country.

In addition to the focal length calculator, I’ll also cover how to convert your lens’s focal length into its x-times optical zoom.

By developing the ability to guess what focal length has been used for an image, you can further understand how lenses control depth and perspective.

If you don’t have the mathematical know-how or time to calculate focal length, these statistics can help you save time and cut to the information you need.

If you’re using a prime lens, the focal length will be fixed to the lens’s native setting, with no adjustable scale to work with.

Most lenses include information about their focal length on the outside of the lens barrel, as well as being listed on the product’s specifications.

Finding the focal length of a specific camera lens is easy, and is typically printed directly on the barrel of the lens for ease of access.

Over time, the design of the quarter has seen several changes. The one we're most familiar with, featuring George Washington on the front and the bald eagle on the back, has been around since 1932. But before that, there were several other designs featuring Lady Liberty and various different eagle designs.

Ultra-wide-angle lenses, as well as fish-eye lenses, create a sense of distortion in horizon lines and other straight lines that other lenses won’t produce.

The more you experiment with different focal lengths, the easier it will be to spot images taken with a longer or shorter focal length.

Fortunately, there’s a straightforward way this can be achieved, using a quick formula based on the full-frame diagonal size compared to the smaller sensor’s diagonal size.

While coins might not seem like a big deal in the grand scheme of money management, they can actually play a significant role in teaching financial responsibility to kids. With the rise of cashless transactions and digital payments, it's easy for kids to lose touch with the concept of physical money. By using quarters and other coins to teach the value and history behind each one, parents can help instill good financial habits from a young age.

Conversely, super telephoto lenses bring the foreground and background elements together and can be used to create interesting patterns and textures.

There are two main types of lenses used in photography: concave and convex. Each has a different effect on incoming light rays.

It’s a great way to gain inspiration and come up with new insights into the shooting process, composition, and technical considerations.

At 35mm equivalent, a 20x optical zoom will provide a focal length of 26.8mm to 576mm, giving plenty of scope for long-distance shots.

This information can be useful when shooting wildlife or sports photography to give a clearer idea of which lens is needed to reach the action.

Concave lenses are thicker on their edges and cause light to diverge away from the focal point while having a negative focal length.

Let's take a trip back to the late 18th century in the United States. Before 1792, the U.S. didn't have a standard form of currency. But that all changed with the Coinage Act, which set up the U.S. Mint and regulated coinage across the country. By 1796, the first U.S. quarters were being minted.

Most photographers who are dedicated to improving their skills will spend a lot of time checking out work from professionals and their photography peers.

On the other hand, convex lenses are thicker in the middle and bring light to a point to create a positive object distance and an inverted image.

This allows you to accurately adjust the focal length while framing your shot, while also understanding how much zoom leeway you have either way.

Unless you’re using a fixed focal length prime lens, you may wish to figure out how to convert your lens’s focal length to its optical zoom.

It’s important to bear in mind that different brands sometimes have different crop factors for their various camera sensors.

Figuring out the equivalent crop factor for different camera formats is a handy way to quickly convert the size of media you can work with.

For example, wide-angle lenses create a sense of space and immersion, while telephoto lenses work well to flatten perspective.

For example, if an object is 50cm away from a lens and produces an image of 100cm, the focal length of the lens will be 33.3cm.

Another way to calculate focal length is by using the lens equation technique, for which you’ll need to know the distance an object is away from the lens and the image distance.
