thankyou
Super simple super smart tarike se explain kiya .
Literally itne sare video dekhe pr bs mudde ki baat aappne krii .
Thanks a lot sir i was always confuse about that focal length fundamental.
Nice explanation, It helps me to get rid of lot of confusion. Thanks.
Yaar.... Level ❤❤❤
You've sorted out the biggest misunderstanding. Stay Blessed Sir ! Your work is adorable... 👌👌👌👌
Very nice and deep knowledge Sir thanks
Aap ne bhaut achhe se smajhane ki kosis kari he
Aap ka smjhane ka tarika mujhe achha laga
Thank you sir ☺️☺️☺️🙂🙂🙂
I have seen lots of your videos but after watching this video I subscribed your channel. Really very awesome information.
very good iformation ,thank you very much .
Great explanation sir, thank you so much again
Bahut hi sahi tarike se samjhaya 👍🏻
Great explanation. Thank you!
A good video containing an important clarification
Nicely explained. Doubts cleared.
Very informative video👍😊
You are a successful Tutor Kunal.Best teacher.
धन्यवाद कुणाल सर...!❣️
Very helpful...
Thank you kunal sir ❤️🙂👍
It was a very helpful video but I would like to say one thing
Angle of view ki jagh field of view word jyda is concept ko clear krega... Bcz angle of view dekhne ka najariya hai.. Aur view of field kitna dekha gya hissa hai..
Thankyou so much for this lovely video. 😊
Good job man! You explained it really well!
Sir nikon our canon me konsa dslr acha colors produce deta he ...ishpe ek video banaye
good job sir .
I like it
Thank you so much your video saved my paper ❤️
Thanks a lot. I have a confusion on how to decide correct focal length for a particular image
Thx brother
thanks sir for this video 😀😀
U r the best teac.also😍
Thanks you so much for explanation
I feel one like from mecould not justify the amount of work you did🙃
helpful bro
Nice sir
Thanks sir what is shutter speed iso apprature also depth of field ? Hi sir it's very much helpful hi myself Rony an VFX student from kolkata
Nice video..
Mr. Kunal, l use Canon 1300D .pls what is the TAB? how to use it?
Bhai concave lens hota ya convex lens pls clear this dout
good job
Wonderful gyan thankyou
Grt video
Sir 50mm lens conon ka best rhe ga Ya yangno ko km reng me pls hlp conon 200d k leye Sir
1 time investment hai, Purchase Canon 50mm f/1.8.
Tnx sir
Sir canon ke sabse aachha lens konsa hai/ which is the best lens for canon dslr
Today I know actually truth about lens focal length thank Sir ♥️♥️
Bhai manual mode ke bareme full details ka videos banao please
Sir, concave lens in a diverging lens. I think convex lens (converging lens) in present in camera's.
What is panorama shoot sir ?? I have samsung galaxy j4 it has these option but I never shoot yet how to shoot it any tips
व्हिडिओ अच्छा है एक अौर व्हिडिओ बनाओ अलग अलग फोकल लेंथ से इमेज किस टाईप के ले सकते है
Bhai lens convex hai ya concave confirm it thanks
Bhai...ek concave lens kabse light ko converge karne laga?
Bahi focal length mobile phone ma 26mm better ha ya 54 mm better ho ghi. Yani pictures konsi focal length ma achi ai ghe
Good explanation but what difference does it make on the crop sensor vs full full frame.. for example if the bird is at 300 mtrs away flying or sitting…. If I use sigma 70-200 lens sigma lens f 2.8 what difference will I get in crop sensor vs full frame… secondly where will I get better image sigma 70-200 or 70-300 nikon 4.5-5.6… at maximum zoom it i.e at 200 mm and 300 mm
Nikon P900 Good Or Bad.?
Sir aapse photography shikhna h kaise karu
Sir jab 2 photo click ki to dono me focal lengths alag alag dikhata hai q
Example kisine 180mm 45mm u sir q plz reply
Sir D3200 ka white balance kese kare
👍
Well lens should be convex lens not concave lens
The great misconception cleared about the multiplication of focal length by 1.5 in crop sensor..... thank you....your simple physics made it so clear..
Outstanding
Sir lense pr jo F likha hota hai ex-f 2.8 or 4 ......what that means ...
Is this means uska F vahi rehta hai...?
Hi Buddy, Just a doubt . as per my understanding conversion happens in CONVEX lens and you said it's bcz of CONCAVE lens. Can you please clarify if am wrong ?
Himanshu Bhargav yes bro...if you see the optics image it is clear that light is coming from outside and converging through different lens elements and the exact point of convergence is present in the concave lens......and where from the lights are diverging to hit the sensor....this is what I understand.
Himanshu Bhargav u r absolutely right
Convergence is for convex lens only
Sir Fleshlight ka use karne Wala video banaye ho to link send Kare ya video banaye
sir mere pas mark IV camra hi mujhhe aysha lensh bataiye jise may runig video lu aur focash aut nahi ho
Manual lens chaiye to Rokinon aur Sigma ke cine lenses ache hai
If u ever had physics as your subject, u would know that focal length is the distance from the centre of lens to the point of convergence (where the sensor should be located). And since it's an array of lenses in a DSLR obviously the center here would mean the resultant center of different lenses in the array. Of course since the lenses are of different varieties, in the array, the resultant center may not be the same as geometric center of the lenses' arrangement.
Focal length is NOT the distance between the point of convergence and sensor location.
+Dr Rajeev Gupta then you mean to say even Nikon is wrong? www.nikonusa.com/en/learn-and-explore/a/tips-and-techniques/understanding-focal-length.html
+Dr Rajeev Gupta you mean to say image sensor is located at the point of convergence?
So even Nikon has its facts wrong? www.nikonusa.com/en/learn-and-explore/a/tips-and-techniques/understanding-focal-length.html
The Photography Blogger The site isn't wrong though your interpretation is wrong. It clearly states that the sensor or the film is at the focal plane. (it's a plane passing through the focus & perpendicular to the principal axis of a mirror or lens.) And of course focus is where the light converges. Hope this helps.
The Photography Blogger Yes, the image sensor has to be at the point of convergence of light. . That's also true going by the article u are referring to.
+Dr Rajeev Gupta quoting Nikon, It is not a measurement of the actual length of a lens, but a calculation of an optical distance from the point where light rays converge to form a sharp image of an object to the digital sensor or 35mm film at the focal plane in the camera.
Doesn't it say the distance between the point of convergence and the sensor?
Not a science student, but this is what I know from my research.
Nice
+zubair khan thank you
♥️
Bro Study Science human eyes. & Amezing world. To understanding this 😅
sir mere pass nikon 7000 h mujhe 50mm ya 35 mm lena chahiye
+bansi lal 35mm se events cover kar saktr ho, 50mm se portraits
what will happen if the focal length is increased or decreased?
nice sir from armaan virk
Dear, at the begining of the video, you were wrong in saying that "there is CONCAVE lens, through which light gets converged..." Actually it will be CONVEX lens... NOT CONCAVE lens.... CONCAVE lens never makes light rays converged... rather divurged... 👍
In concave lens divergence is happen not a convergence
Like it...bilkul easy way se smjha diya...baki sab to bakchodi kr rahe...❤❤
By the way the cover photo u used for your video is much closer to the truth than the entire explanation in the video (which is sadly wrong)
Koi esa lens hai jo nikon p900 jtna zoom dy?
150 600mm on crop sensor body
Concave nahi convex lens hota h
You explained everything but couldn’t explain the difference in photograph at distance
Aree ! Kyu bolte ho last tak dekhna....why you beg...everyone who makes video ...begs...never do it....let the viewer decide what he wants from him.😊
very good iformation ,thank you very much .
