Today everyone click photos with their Mobile Phones because today their are lots of cameras available in mobile minimum 5 cameras.
On the other hand if we talk about the camera numbers so there are different properties such as 3x zoom, 5x zoom and ultra wide.
If we talk about proper DSLRS cameras their lenses come along with different properties and with different numbers as you will see 11mm lens and if you go with premium lenses you will able to see 50 mm lens, then their is one more popular lens 70200 for a magnificent zoom.
For e.g. if you have I phone 15 pro max here you will find 5x optical zoom 120mm camera, now here you will find that how I Phone 15 pro max 120mm is totally different from that of DSLRS 120mm.
ring camera:BRIEF EXPLANATION:
We often say that camera sensors or megapixels are not well enough, apart from that there are lots of elements are together which makes a photo good or bad.
So, it is quite clear that a lens plays a very important role for a great picture Sometimes, what happened you purchased a cheap camera but lens you are using is very expensive and it is providing you a very good quality. Here the thing that you want to know is that lens plays a great role.
ring camera:LENS:
Most common thing that is present in any lens is that its Focal Length. Now, the question arises,
ring camera:What is Focal Length?
Focal length is basically a physical distance present between the centre of the lens and its focusing point, now it depends on properties of the lens that What are the elements present inside it and it also depends on the curvature present inside the lens.
Lens used to bend the light and completely focuses on one particular place and you also wants that focus of lens should be on its sensor by which if light enters the lens it will automatically converges and focuses on that place where sensor of camera is placed by which you will get a sharp photo this distance is called as Focal Length.
Focal Length basically defines a particular property of lens which is the size of lens. If size of lens is small its focal length is also very less.
Now, think what will be the difference of different focal lengths the difference is very unique, depending on how much area you are capturing while taking the photos.
If you go with lower lens let’s say 11mm lenses that is available on your mobile’s ultrawide camera they are approximately 16mm equivalent by which you will get wide field of view. But, by standing on that place if you change your lens whose focal length is much so you will get a tele photo shot and background will also get converged and your photo will be very unique this is the main property of the focal length.
ring camera:OTHER SCENARIOS:
Different focal lengths like 30mm, 50mm etc.is not for zoom it is also used in film making for different scenarios. If we talk about comedy scenes in the movies that are being shot with ultrawide which brings a different effect.
If we talk about some heroic shots in movies it is being shoot in the super tele photo and it comes with the different perspective, here it defines the properties of lens.
Sometimes, if you feel like you are looking very thin in a particular photo or if you want to look thin in a photo for that you have to take a shoot on wide angle lens so you might get that look.
ring camera:APERTURE:
You usually heard about the number along with camera lens like 1.8,2.8 etc. and we usually thinks if we use this number in low quality like 1.8 or f2 so by using that you will get magnificent blur in your background which is sometimes true but here focal length also plays a very big role.
Here the main thing you must understand is that aperture simply what is the opening of lens and how much is its size is?
How much light it is able to bring towards the sensor.
ring camera:MOBILES:
Now, if we talk about mobile here the sensors are small, lenses are tiny. So, when Apple said that the third camera is 120mm camera which is the equivalent of five times zoom because if we count 24 mm then 24*5=120mm.
Now just think the lens present in the IPhone and its focal length is 120mm.Can physical distance is of 120mm inside the phone? No, its not possible.
Because it is always equivalent to a full frame because here in IPhone sensor is small frame is also small, if we talk about the actual focal length of IPhone is it is roughly 15.5mm.
If 15.5mm comes along with 2.8 aperture so if we calculate it its opening size which exactly comes it is just 5.5mm so there is a massive difference between DSLRS camera and a phone camera because in DSLRS you will get sensors so big that there is no match with that of mobile phones sensors you can’t even compare, so you must understand now that these properties can change your photos completely.
If we only talk about Aperture for example we take a photo with 35mm lens and aperture is 2.8and on the other hand same photo with same framing and aperture is again the same 2.8 but this one we take from 120mm you will instantly look at the difference that aperture is same but then because the Focal Length is more you will find out that the background blur is very prominent and is much more.
Now, you will clearly understand that how all these lenses give you the power to express, they give you the power to completely change the story because they have different properties and these lenses are useful to you in different ways whether its aperture is 1.8 but still because it is of 11mm lens the blur you will get is not that prominent but on the other hand with the telephoto lens the blur you will get is of next level.
