How to perform hyper focus with Canon EF 11~24mm F4 L USM ?

Dianoban — Thu, 10 Dec 2020 12:30:46 GMT

I have been using Sony a7II and many vintage primes for shooting landscapes. Recently, I interested in Canon EF 11~24mm F4 L USM, attracted by its abilities of the ultra-wide abiltities. I have a very serious problem. I do not know how to set the lens for hyper focusing when I shoot land scapes.

How to perform hyper focus when shoot landscapes with Canon EF 11~24mm F4 L USM, please ?

Thanks.

Greetings,

Is this hyperfocal distance?

With a landscape?

Usually this is needed for pictures with great depth where you want your foreground and background to be as sharp as possible.

Tell us about your use case, shooting scenario or subject. Maybe the term you are using isn't what I'm referring to.

Get a hyperfocal distance calculator - possibly for your phone - put the lens in manual focus and set the distance on the scale.

You will find that for a wide angle lens, it will probably be just a few feet in front of you. 8^)

For example, this page:

Shows that at 20mm and f/4 the hyperfocal distance is 4meters. Set the distance scale there and everything from 2 m out will be in focus!

And, at f8 or f11 or f16 just mounting it on a camera will put everything in focus! Especially at the 11mm side but seriously this is a super easy lens to focus.

This is the best course of action. Look it up on a Depth of Field table, chart, or app. As noted by someone up above, it will be a very short distance. I use my manual focus Rokinon 14mm at f/5.6 a lot. I dial in the hyperfocal distance, and everything beyond 2-3 feet is tack sharp.

Notice the bush on the right. I could reach out and almost touch it.

Yes. It is hyperfocal distance.

Yes. Landscape is what I am thinking about.

I have been using five vintage primes, 55mm~20mm, on Sony a7II for shooting landcapes. Usually, I rely on hyper focal marks on these lenses.

Interested in buying a Canon DSLR & the ultra wide 11~24mm F4 L USM lens. There is not hyper focal marks on this lens. Yes, I can guess, based on the experiences of usung a 20mm lens. But I feel a bit nervous.

Appreciate your help.

Yes. You are right. For ultra wide lenses, maybe no need to rely on hyper focal marks or hyper focal distance calculator. Everything is acceptably sharp or clear from approx 1M to Infinity in my landscape images if I shoot with my 20mm lens & set the aperture at f8. With any ultra wide lenses such as 11~24mm, everything in the image range from .05M to infinity should be acceptably sharp or clear if the lens is set at 12~14mm & F8. This is only guessing. It seems that there is no need of any hyper focal marks. But I feel unease.

Tanks for help.

Yes. This is what I have assumed, based on the experience of using my 20mm lens. But I feel uneasy because there is no hyper focal marks to rely on.

Appreciate.

This is what I am going to do. Use manual mode, f-stop 8~11, I assume everything in the range of 0.5M~infinity would be acceptable sharp.

Thank you and thank you everyone for your kind assistance.

Manual mode is not needed unless you just like it. This is a case for Av mode, far more easy. Set Av mode and set it to f8 (whatever) and choose a respectful ISO. Let the camera do the rest. The lens can stay in AF, too. You can focus on a closer object then lock focus, recompose, and take the shot.

Pick a wide angle lens and find out the distance that enables the maximum focus. You cannot hyper focus an object that is very far away from you. So find out the distance that your lens allows you to do hyper focus.
