What does 35mm focal length with 10x optical zoom mean?
This means that if the camera you’re buying says 35 mm focal length with a 10x optical zoom, this means the minimum distance of the lens is 35 mm and the maximum zoomed-in distance would be 350 mm.
What’s the mm equivalent of 8/10/18x etc optical zoom?
Re: What’s the mm equivalent of 8, 10, 18X etc optical zoom? If your camera is a FZ28, the equivalent focal lengths are 27 mm to 486 mm, other cameras have different range, the 18 X as pointed by the other replys, is the ratio of them.
What does 10x mean on a lens?
A larger number signifies a stronger magnification capability. Keep in mind that not every camera’s “10X” optical zoom measurement is the same. Manufacturers measure the optical zoom from one extreme of the lens’ capabilities to the other.
How to choose the right zoom lens for your camera?
Take the maximum focal length that the interchangeable zoom lens can achieve, say 300mm, and divide it by the minimum focal length, say 50mm. In this example, the equivalent optical zoom measurement would be 6X.

What is a 10x optical zoom in mm?
Now, at MWC 2019, it has revealed that the phone will be officially out in the spring. Having a 10x zoom on a camera phone is no mean feat: it means the device will offer a zoom ranging from 15.9mm to 159mm (the equivalent of).
What focal length is 10x zoom?
Comparison with Camera Lens Focal Length For example, a 10x binoculars magnification is equivalent to a 500mm super-telephoto lens. The longer the focal length, the more likely to have camera shake, hence making IS function a more crucial criteria when choosing a binoculars.
Is 10x zoom enough?
Zooming in to 100% on the 10x zoom image, it’s clear that there’s not a lot of detail captured. Realistically, images taken with the 10x zoom are not going to be of sufficient quality for printing — pristine-quality zooming will remain the territory of a DSLR with a telephoto lens, for now at least.
What is 100X zoom in mm?
So, each whole number of digital zoom adds 24mm of equivalent focal length. The 100x digital zoom is like a 2400 mm telephoto on a 35 mm camera.

How many times zoom is 300mm?
Here is an example: For a 300mm lens, divide 300 by 50 to get 6x magnification. Or divide 300 by 100 to get 3, then multiply 3 x 2 to get 6x.
What is the difference between 10x and 5x?
5x means that the ratio from wide to long focal length is 5 to 1 for example 28mm to 140mm, 32mm to 160mm etc. 10x would mean 28mm to 280mm, 32mm to 320mm etc. Simply multiply the lower number by the zoom ratio.
What is a good optical zoom?
The best optical zoom comes down to what you are wanting to photograph. For example, if you are into wildlife photography a 2x optical zoom is not going to get you close enough to the animal. You will need 10x or even 30x optical zoom to get closer.
How far can 20x optical zoom See?
However, a rough rule of thumb is that with a 4x zoom ratio you can ID someone 100 feet away. Following on from that, for identifying someone at 200 feet, you’ll need a 20x zoom ratio, and a 30x zoom ratio for 250ft.
What is 50x zoom equivalent to in mm?
24-1,200mmThe 50x optical zoom alone is the focal length equivalent of 24-1,200mm on a full frame body.
How many mm is 20x zoom?
Its “focal length equivalent” is from 28-560mm (which is where the 20x number comes from, and also approximates what the focal length of lenses would have to be on a 35mm film camera or full-frame dSLR.)
How much zoom is a 200mm lens?
So, a 200mm lens on a 35mm frame is about a 4x “zoom” to your eyes. On the 20D with the 1.6 crop factor, 200mm is about a 6.4x “zoom” ((200 x 1.6) / 50).
What focal length is 2x zoom?
All zoom ratios have their focal length equivalents. Many times when you are reading about a compact camera, they will give both types of measurements. For example at 2x zoom has a focal length equivalent of 35mm to 70mm and a 4x zoom has a focal length equivalent of 35mm to 140mm.
What does 10X lens mean?
We all know that 10X means that the objective lens has an effective magnification of ten times life size and when combined in the compound with a 10X ocular lens will give a final magnification of 100X (10 X 10).
What is 5x optical zoom equivalent to?
In smartphones, manufacturers have started using periscope lenses for better optical zoom. They’ve been able to put 5x zoom lenses (roughly equivalent to the magnification of a 100mm lens on a DSLR, so pretty good) in their flagship phones without making them any thicker.
What is the focal length of a zoom lens?
The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters (e.g., 28 mm, 50 mm, or 100 mm). In the case of zoom lenses, both the minimum and maximum focal lengths are stated, for example 18–55 mm.
What is optical zoom?
Optical zoom measures the actual increase in the focal length of the lens. Focal length is the distance between the center of the lens and the image sensor. By moving the lens farther from the image sensor inside the camera body, the zoom increases because a smaller portion of the scene strikes the image sensor, resulting in magnification.
What is the maximum focal length of a 10x zoom?
However, if the digital camera offers some additional wide-angle capabilities and has a minimum 28mm equivalency, then the 10X optical zoom would only have a maximum focal length of 280mm. The focal length should be listed in the camera’s specifications, usually in a format similar to “35mm film equivalent: 28mm-280mm.”.
How does a zoom lens work?
With most digital cameras, the zoom lens moves outward when in use, extending from the camera body. Some digital cameras, however, create the zoom while adjusting the image size within the camera body. Continue reading to find more information that can help you understand camera zoom lenses better.

What is a multiplier lens?
In other words, the “multiplier” is the difference between the smallest and largest focal length measurements of the lens. For example, if a 10X optical zoom lens on a digital camera has a minimum focal length of 35mm, the camera would have a 350mm maximum focal length. However, if the digital camera offers some additional wide-angle capabilities …
How to measure optical zoom?
With an interchangeable lens camera, you can calculate the optical zoom measurement yourself by using a simple mathematical formula. Take the maximum focal length that the interchangeable zoom lens can achieve, say 300mm, and divide it by the minimum focal length, say 50mm. In this example, the equivalent optical zoom measurement would be 6X.
Why is it important to understand the zoom lens?
It’s important to understand the zoom lens because the two types of zooms are vastly different from each other. In the battle of optical zoom vs. digital zoom, only one — optical zoom — is consistently useful for photographers. With most digital cameras, the zoom lens moves outward when in use, extending from the camera body.
What does a larger number mean on a camera?
A larger number signifies a stronger magnification capability. Keep in mind that not every camera’s “10X” optical zoom measurement is the same. Manufacturers measure the optical zoom from one extreme of the lens’ capabilities to the other.
What is the difference between focal length and optical zoom?
The focal length (read as ‘XX’mm) is the strength with which the lens can focus on an object, while the optical zoom (the number ‘X’x zoom) is the strength of the total zoom you can achieve. This means that if a lens has a larger focal length, it has a narrow angle of view and a smaller focal length implies a wider angle of view.
What is the best zoom for indoor photography?
Again, a low zoom (2x to 5x), wide perspective camera would be excellent. If you’re taking an outdoor shot, space won’t be much of a bother and you’ll also want to take pictures of things far away. This calls for a larger optical zoom (5x or more) and a decent perspective.
What zoom lens do you need for nature photography?
If you’re out hiking, a camera with a 5x or 7x optical zoom would be your best bet. It will get you the perfect still, without compromising on a larger perspective or on details.
What is the maximum zoomed in distance for a 35mm lens?
This means that if the camera you’re buying says 35 mm focal length with a 10x optical zoom, this means the minimum distance of the lens is 35 mm and the maximum zoomed-in distance would be 350 mm. Now, a lens of 28 mm focal length and 10x zoom would mean the minimum distance is 28 mm and the maximum is only 280 mm, …
Is it necessary to zoom in on a photo?
The answer kind of merges with the above situation of indoor photography. If you’re outside in natural sunlight, a good zoom is not really necessary if the subject is close enough. If you’re inside however, this means two things; poor lighting and the restrictions on flash. It is a little rude after all, to throw a flash into a person’s face indoors in poor lighting. Here, you’ll need a good enough zoom of around 10x or 12x to get close-ups without having bad lighting get in the way too much.
Is digital zoom the same as optical zoom?
As far as optical zoom is considered, it is generally a good practice to stick to optical and not digital. A digital zoom is not the same as an optical one. Another thing to look out for along is the focal length of the lens.
How wide is a 10x zoom lens?
For DSLR zooms, it seems 10x is pushing it. For these type of ‘superzooms’ they seem to centre the lens so it goes from reasonably wide (24 or 28mm) to reasonably long (240 or 280mm oe less).
What is the highest zoom lens?
Your lens it highest zoom is probably around 500mm. To get the same effect on a DSLR, you should find yourself a 350mm lens (APS) or a 250mm one (Olympus). For the widest view of your lens, the calculation is identical. The FZ35 has a 28mm equivalent lens, which corresponds to about 19mm (APS) or 14mm (Olympus).
How many mm does a 12x camera need?
So, in order to match that particular 12x camera with DSLR lenses requires 16.7mm to 200mm. Note, Olympus and Panasonic DSLRs use the 4/3 system and the crop factor is 2, so the required range would be 12.5 to 150 mm.
What does 18x mean?
18x only tells you the difference between the shortest and the longest focal lengths the lens can do – not what the focal lengths are themselves.
How wide is a 300mm camera?
There’s just one more thing to know. The typical consumer DSLR uses a sensor smaller than full-frame, and has an associated crop factor . Typically this is about 1.5 or 1.6, so the 25mm wide setting becomes 25/1.5 = 16.7 mm and 300mm becomes 300/1.5 = 200 mm.
How many mm does a Panasonic TZ6 zoom in?
For example, the Panasonic TZ6 (ZS1), has a 12x zoom, going from 25 to 300 mm .
How many mm is 18x?
18x probably puts you over 500 mm (35 mm equiv), but why don’t you look your camera up in the camera database ( http://www.dpreview.com/reviews/specs.asp )? The info is there.
How many mm is a 10x zoom?
It will show you something is “mm”, generally starting from around 5 mm. Since it has 10X zoom the reading would be 5mm to 50mm (5X10 = 50). Now, since the camera has 6x crop factor, we will multiply both end of focal lengths by 6 to get a “35 mm equivalent” focal length.
What is the focal length of a 55mm lens?
With 55mm – 250mm, the actual focal length would become 55 X 1.6 = 88mm to 250X1.6 mm = 400mm. So, here we actually have a lens with 88mm to 400mm in “35 mm equivalent”.
How to tell if a point and shoot camera is 30mm?
First look at the lens of the point and shoot camera and check what it reads. It will show you something is “mm”, generally starting from around 5 mm. Since it has 10X zoom the reading would be 5mm to 50mm (5X10 = 50). Now, since the camera has 6x crop factor, we will multiply both end of focal lengths by 6 to get a “35 mm equivalent” focal length. In this case it would be 5X6 =30mm and 50X6 = 300mm. So, actually it is 30mm-300mm in “35 mm equivalent.
How to tell the size of a full frame camera?
Let us compare both of them to “35 mm equivalent”or to the full frame camera. The size of sensor of full frame camera is 36mm X 24mm (35 mm equivalent). Every camera’s technical specification provides the size of its sensor or the crop factor. You can find this crop factor by dividing the 36mm by longer side of your sensor dimension. For e.g., if you have a Canon APS-C body, then you will have sensor of size 22.3mm X 14.9mm. Now, divide 36mm by 22.3mm, which gives you 1.6. This is your crop factor. Smaller cameras, point and shoot cameras and four third systems have even smaller sensor, so bigger crop factor (refer to the image below). For exact crop factor of your camera, refer to the technical specification provided by the manufacturer.
How to find the crop factor of a camera?
You can find this crop factor by dividing the 36mm by longer side of your sensor dimension. For e.g., if you have a Canon APS-C body, then you will have sensor of size 22.3mm X 14.9mm.
How to find focal length of a Canon camera?
To calculate the actual focal length of your lens on your camera, just multiply the focal length with the crop factor. So, 50mm focal length on Canon APS-C is equivalent to 50 X 1.6 = 80mm in full frame format. Smaller point and shoot cameras have crop factors to the tune of 6 or 7. So even if the focal length of the lens on smaller camera is 10 mm, it is actually 60mm in “35 mm equivalent” format.
How to calculate focal length of a Canon APS-C?
To calculate the actual focal length of your lens on your camera, just multiply the focal length with the crop factor. So, 50mm focal length on Canon APS-C is equivalent to 50 X 1.6 = 80mm in full frame format. Smaller point and shoot cameras have crop factors to the tune of 6 or 7.
