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:

Good. If you understand the basics, then you will understand my suggestion that you invest in video lights. Many people use them.
if you have any instruction and values that may use it in my camera and reach to get more thought, I will love it, do you have it, please?

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.

"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 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.

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.
