Happy Holidays, CC!

It's a good chart. Here's a few things I'd add...

For 35mm and APS sized formats (most DSLRs), diffraction distortion will start to become noticeable with most lenses starting at F11 or F16, becoming more noticeable the smaller the aperture. Also most lenses will not be at their sharpest until stopped down one or two stops. So a F/2 maximum aperture lens will probably be at it's sharpest somewhere between f/4 and f/5.6.

Telephoto lenses are more subject to camera shake than normal or wide angle lenses. A good rule of thumb for hand holding the camera is to use a shutter speed that's at or faster than the focal distance. In other words, a 200mm telephoto would need a shutter speed of 1/200 or shorter. This still means you need to use good steady hand holding technique.

Wide angle lenses have much more depth of field than telephoto lenses, so it's a good idea to consult the DoF marks if the lens has them (most modern lenses don't), or a DoF chart for the focal length you are using. Smart phone apps are also good for this.

Worth printing, laminating and sticking in the camera bag.

My problem is taking pictures in dark situations where it is difficult to see the settings. You want to take that great night shot but can't see to make the changes.

If you are not totally familiar with your camera, it is difficult.

situations I keep a small led flashlight in my camera bag and found one that will clip onto my camera strap. I do know my camera but sometimes you just need to see anyway.

I knew my old 35 mm SLR and could set it up in the dark, but I was much younger, my eyes were better and cameras were simple by today standard.

I also have a ball cap clip on flash light that has red light for situations where even a pen light would be unwanted.

I have access to the latest flashlight technology because I work for a battery company who is also a large producer of flashlights.

Great minds think alike.

I got a headlamp with a red bulb. It works really great in night-time situations without blinding you.

and I already have one that does the red along with white and flashing white.

I guess next one will go in camera bag.

We get all the latest to test before they go to market.

I was thinking of printing this and then laminate it, but why not send through with a batch of prints on a 4x6 print, then stick it in your bag. IT would have some durability. But when it does get too damaged, print another.
