can not use F22 or iso less than 400 with lens 17-55 , help me ?

[ Edited ]

I have canon 80d and lens EF-S 17-55mm f/2.8 IS USM, when I need to reduce the F to F22, the light will be very low or dim especially in the video mode, So in this case, I must increase the iso to about 12000 , but the last value would produce the video with very noise. so with my lens, I can not definitely use the value of F22 which is very useful in some case to reduce or get rid of Blur for the background of things, so please recommend me? I Need your help please.

see my video below to understand me completely:

Shooting with an f/22 aperture may require that you use very high ISO settings.  That’s how it works.  You have to give up something to gain something.  

I suggest that you take the time to learn more about basic photography, so that you can gain insight into your video settings.  You should do a web search for articles about “ exposure triangle “ and “ depth of field “.  The Canon DLC, Digital Learning Center, is a good place to start.

That is a link to the first of a series of short videos about basic photography.  Hope this helps.

I am very thank you for your response to my inquiry, I know about the link before, also I have a good information about Aperture and iso .and also the exposure triangle “ and “ depth of field as the following links:

 

https://www.exposureguide.com/exposure/

 

 

and :

https://www.exposureguide.com/iso-sensitivity/ 

 




 But I have seen some videos they increase the F value to F22 without a big dim of footage. So, I can not use iso 800 and just F=F11 without the darkness of the footage. so I hope to image that F=F11 the recorded videos will be very dim, and when I enforce to increase the ISO to 7000, the noise will be very obvious.

Good.  If you understand the basics, then you will understand my suggestion that you invest in video lights.  Many people use them.

Forgive me for having to point this out, Stephen, but it can also be seen as an indicator that not everybody in this forum has 20/20 vision - and of the fact that a) the forum's default font size is quite small, and b) unless the poster thought to change the "font family", postings do not respond to the browser's "text size" setting. (Do you, by any chance, have enough clout to get that changed?)

 

I hope to have a cataract operation on my bad eye sometime this winter. But my wife, having already scheduled hers, has first preference. If we have them at the same time, we have no one to drive us around.

Hi Bob,

 

Usually, if eyesight is an issue, one would change the overall settings in the OS' accessibility options to compensate for their malady, rather than subject everyone else to what can be seen as a netiquette issue. If all else fails, "Control and +" always does the trick for me when I need to zoom in on something.

I can offer no recommendations for specific products.  Everyone has different needs.

 

You should seek the advice of a reputable vendor that sells video gear.  I have had good results with B&H Photo Video in NYC with their advice for photo accessories.  They have experts in various topics related to shooting video.  Most of their online experts work for equipment manufacturers.

You need sufficient light to drop your ISO several stops.  You will likely need more than one to avoid hard shadows.  Do not be alarmed if the recommend four, either.

I agree. Do not use all caps. It has an established inference.

 

Robert I hope the cataracts surgery will fix the problem and all is well.

A lot of Canon stuff. Along with, a lot of other stuff.

Thanks, Ernie.

 

But I wasn't defending the use of all caps. Stephen's injunction was against using boldface or a larger font size, neither of which I see as falling into the same category as all caps.
