The zoom capacity of a zoom lens is generally quoted as the ratio of the longest focal length to the shortest focal length, without regard to the image size. So its 55/18 or about 3:1 Zoom ratio. It is 18–55 mm.
What magnification is 55mm?
You are mixing up two things: lens magnification and viewfinder magnification. The 18-55 lens has a maximum magnification of . 34x at 55 mm. That just means that at 55mm focal length, if you photograph something that is 1″ high, the largest it can be (depending on subject distance) is .
Is 55mm lens zoom?
The Canon EF-S 18–55mm lens f/3.5–5.6 is a Canon-produced wide-angle to mid telephoto zoom lens for digital single-lens reflex cameras with an EF-S lens mount. The field of view has a 35 mm equivalent focal length of 28.8–88mm, and it is a standard kit lens on Canon’s consumer APS-C DSLRs.
How far can 55mm zoom?
An 18-55mm lens on a camera with an APS-C sized sensor is equivalent to about 28-85mm full frame (FF). It is a general purpose lens that goes from medium wide angle to short telephoto. If you are photographing a group of people at 8-10 ft you will be able to get 3-5 people in the frame at 18mm but probably only one.
What is 55mm in optical zoom?
For example a 18-55mm lens would have a 3x optical zoom, and a 18-200mm lens would have a 11x optical zoom.
How many times zoom is 500mm?
So, using the formula, we now know we need a 400mm lens to approximate the magnification of an 8x binocular and a 500mm lens to approximate a 10x binocular.
What is zoom range?
Put simply, the zoom range is the difference in magnification from one end of the zoom range to the other. With a regular DSLR or mirrorless camera kit lens, the lens will offer 3x the magnification when you’re fully zoomed in compared to when the lens is zoomed right out.
Does 50mm lens zoom?
‘. With 50mm prime lenses, instead of zooming with your hand, you will zoom with your feet. You’ll get closer to your subject to isolate it from a distracting background, which will mostly be abstract shapes (especially if you have the f/1.4 version).
What does 18-55mm mean in lenses?
A reading of 18-55mm is a focal length range. It means that you can change your focal length. The widest angle is 18mm, and you can zoom in to 55mm. Common zoom lenses are 16-35mm, 24-70mm, and 70-200mm.
Is 50mm better than 18-55mm?
The difference in aperture between these lenses is a big one. The 18-55mm has a variable aperture of F/3.5-F/5.6, while the 50mm is a fast F/1.8. With a wider aperture, the 50mm can perform better in more situations.
Is a 18-55mm lens good for zoom?
The best thing about the 18-55mm lens is its versatility. At 18mm, it is fairly wide-angled and is great for landscapes. In the middle of its range, around 35mm, it is perfect for street, travel, and documentary photography, while the short telephoto zoom of 55mm works wonders for portraits.
What is 55mm lens used for?
The 55mm end makes for a short telephoto lens, ideal for compressing perspective when taking portraits or closing in on small details. That doesn’t mean you can’t use the middle focal lengths, and there are times when you can’t avoid them.
How far can a 55 250mm lens zoom?
At 250mm, the maximum magnification is 0.31x, which does not come into the true 1:1 macro range. The closest focusing distance is 1.1 metres.
What does 2x zoom mean?
The on-camera zoom lens can zoom in and out optically by using the optical formula built into the lens.For a 2x digital zoom, the 2x area is taken out and blow up using software to the size of 1x.
What does 60x zoom mean?
Pushing the zoom limit to 60x optical means that birdwatchers and some long-distance sports photographers will be happy. The lens itself is reasonably wide at 24mm and extends to 1440mm (35mm equivalent).
How far is 50x zoom?
24-1200mm
The 50x optical zoom lens is a 35mm equivalent of 24-1200mm, which can be extended to 100x using Zoom Plus. Thanks to its Ultra Sonic Motor the lens has near-silent zooming.
How far can a 18 55mm lens zoom?
Zoomed in fully, it’s the equivalent of 82mm on a full-frame camera. So it’s wide enough for general everyday shooting of places and landscapes while also zooming in enough to be useful for flattering people photos.
What does 10X zoom mean?
An optical lens has a set of many individual lenses which move to enlarge the image. 10X means, the lens has the power to enlarge an image 10 times between normal focal length and Tele focal length.
What is 200mm zoom?
Very straightforward. It’s 4x compared with 50mm. 200 ÷ 50 = 4. For distant subjects, image size is proportional to focal length, so when the focal length is 4 times longer, the image size will be 4 times larger.
What is a 30x optical zoom in mm?
30x optical zoom. Extend your reach to the max with this fast 27 mm – 810 mm f/2.8-5.6 Carl Zeiss Vario Sonnar T* lens. The 30x magnification range is nothing short of incredible, allowing you to zoom up to distant subjects while still maintaining the clarity that only optical zoom can provide.
What does a 50 mm lens do?
The high speed and wide aperture of a 50mm lens can also provide shallow depth of field. This gives you huge creative scope to blur out backgrounds and focus attention on your main subject. 50mm lenses also give attractive out-of-focus highlights (also known as bokeh).
