Depth of Field - A Visual Guide to the Lens

[DSLRCamera]

Thanks CoolDudesJunk. I just had to make the video since it was so easy to understand with this lens. Glad you enjoyed it!

[CoolDudesJunk]

One of the most solid tutorials on lenses I've seen. Thanks :)

[jopezu]

it's amazing that with this purely manual lens, and all of the markings, how easily all of the main photography concepts can be explained.

thanks for posting this video. those markings give an immediate mental visualization on the f/stop and focus depth relationship.

[Gameinggames]

All lenses should have this its awesome

[PoolGuy300]

Thanks for this video. This may be the single best video on photography that I've seen in the last year. It brought all these competing variables together for me in a short, easily understood video. Nicely done.

I wish the newer lens are that detailed. Anyone know if I can pull up these scaling info in the newer Canon cameras?

[malachy1847]

@vd853 These were old Long Tom Zoom lenses with the optics of the 'Ass of a Bottle'... the modern Zooms have a two touch system rather than the Trombone lenses of old.. the 'Prime Lenses' [Fixed Focal Length' should have these graduations still on same... it all depends what your into sports, landscape, or portrait,..sometimes you want serious depth of field.sometimes it's the last thing you want...Hyperfocal depth of field is mainly for Landscape, where as sports tend to look for the opposite

it's a great tutorial, but it would be nice to show some actual pictures and their settings and alight meter.

lovely lens!

[malachy1847]

@davetheraveishere They were good in their time but the New Lenses knock spots off them due to those number crunching computers thus making the a lot of the old problems a thing of the past,.. deviations.. like Pincushion and Barrel distortion... plus the super newgeneration lightgathering materials the new lenses are now within everyones reach... once you would have to take a mortgage to buy a good lens not so today....... ...

thanks for posting!

I didn't understand the last comment - why might the subject look out of focus at 15' through the viewfinder but then be in focus when the shot is taken?

[toad2039]

wow this tought me so much i watchd it twice and took notes

[idofha]

Thanks for the Video. I am just glad that now all we have to do is click and get out f #'s.

[hue890]

that was a good vid

[DSLRCamera]

Thank you. It took some time to understand this when I was starting (back in the 80's). Then I got this lens and the light bulb went on.

Had to share it.

[Nickamsweet]

must admit that lens is very helpful with those guidelines!!

i am just starting myself and trying to get to grips with all these settings...

[gogolusa]

Outstanding demonstration! Thank you.

How do you covert the DSLR lenses zoom to optical zoom(ex. 5x optical zoom)?

What focal lengths are wide angle, standard and telephoto?

Thanks

[bleeddieagony]

From what I know, everything below 28 mm is wide angle, 28 to 50mm is standard and everything above is telephoto. To calculate optical zoom on a DSLR zoom lens (given it isn't a prime or fixed focal length lens), simply do the ratio between the maximum focal length and the minimum one :) For example the 18-55 mm lens has a zoom ratiot of 55/18=3.05 x. Did that enlighten you?

This lens is a Tokina Magnicon Auto Zoom Marcro 1:3.8-4.8 F=28-70mm 520 No.K8711292

[Finegold2]

what lens is that because i would love to buy one

[lqqkitslory]

Thanks for doing this video, you explained the subject really well and its made F Stops much clearer to me!

[villrg0a]

thanks for posting, its a vivitar right?

[DSLRCamera]

This is a Magnicon Lens made by Tokina

[rebelshotmedia]

This was a great video. I liked the "way" you explained the topic and your presentation was good.

[getpballs]

Great video, this lens is for film camera only right?

[DSLRCamera]

It was purchased for my Nikon N2000 Film camera. It works just fine on my Nikon D70 as long as I use the camera on manual mode.

[getpballs]

That's a good lens to teach about how they work though. When will i see more videos from you? I think you should make some more =]

[DSLRCamera]

I'm planning on making more! I need to find (Make) the time.

Thanks

Ed

[getpballs]

Great! i'm already subscribed

[Bealll95]

I think this is a really good video that helps to explain f-stops. I work as a photographer and don't think I could explain it every remotely near as well as it is explained here. Every new photographer should watch this video!!!
