I would add for your consideration to 1/focal length any crop factor the camera may have as that crop factor narrows the field of view. 1/focal length I consider to be a minimum shutter speed with no VR or IS. So, for a Nikon Dx the crop factor would be 1.5 and the the math would give 400 x 1.5 or 600. So, I would shoot at 1/640 as an ideal minimum.
The other consideration is whether the subject is moving, how fast it is moving and how it is moving relative to the focal plane and camera sensor. I shoot trains locally that are moving 50-70 mph coming toward or going away from me. I generally try to shoot at 1/2000 even with my 24-70. If I am shooting with the subject nearly parallel to the sensor, such as at the drag races sometimes the subject is moving across the sensor's view even faster than if shooting a 3/4 view of the subject. It is not that hard to do the math to determine how far the subject traveling 60mph travels in the time the the shutter is open 1/60, 1/500, 1/1000 or 1/2000 second. But the amount might surprise you. Stationary or slow moving subjects are easy, as defined in the paragraph above.

1/focal length = safe shutter speed
VR or IS allows for slower shutter speeds, but keep in mind that everybody has different abilities.

No Sir. I worked for a handful of companies and a number of clients over the past years. If you want to PM me and let me know more details of where, when and what role that is fine but I don't want to chew up space in the forum with stuff few would care about.

The first image is the default view with zero EC which I suspect is the same on most Canon DSLRs. The second image is the EC adjustment screen that is displayed when you select EC to change it. The last shot is the update to the first screen after the EC is set to +5. I don't know what could be more clear and nothing is hidden. Of course you can always over or under expose in Manual as little or as much as you want. But that would never help you in the other shooting modes. So, I don't think, you have any argument and your generalization was simply wrong for Canon DSLRs. The End.

That's interesting. Your middle image changes your meter 'centering', but you still have +/-3 on the EC scale even in your third image. I'm not sure I'd ever want to do that, since I can just switch to manual and over/under expose as many stops as I please, and I'd be afraid I would forget to change the meter centering back for the next time I would shoot.

You are wrong...ask a drag racer...it is for what the car can do and the driver and crew trying to get it to do its best repeatedly...

I don't know what Canon you are using but I assure you on my 1Dx MkII it is plus or minus 5 stops of EC.
If you still don't believe me then I guess you can download the manual from the Canon website and read it for yourself...
Or look below at the specs from the B&H site...if you trust B&H...
Looking forward to lunch...

Maybe Nikons are different, but with Canon it's 3 stops. I frequently need more than that, so I have to switch to manual.

Enjoy!!! It doe IR wireless I believe but not built in radio.
It will be a good Speedlite to learn a lot with Tom!!!

Yes, even though my camera can go 5 stops over or under I am not sure there is a great deal of use for that much compensation.

As you can imagine different cameras have different settings the Fuji XT2 is plus or 3 I'm sure some canons are five and I've seen some even higher than that but I find if I go much more than three in either direction it's either going to be way too dark or way too light

Would you like to bet lunch on that???
You can send the money to my PayPal account...

In the Av or Tv modes you can only dial exposure compensation up or down a maximum of 3 stops.

Not sure where you are getting the 3 stops of over or under exposure. My Canon with a proper exposure can go over or under 5 stops.

Correct, but whatever you wish to do, you can do in either Av, Tv or M (unless it's over/under expose by more than 3 stops).

I shoot 90+ percent of my shots in Shutter priority as I am often shooting fast moving subjects or sports and need to freeze motion to have a useful shot. I do shoot panned shots of drag racing sometimes with a slower shutter speed. I shoot portraits in manual most of the time. I really don't see the big deal about shooting in Manual mode vs Shutter or Aperture priority mode. You still need to understand the exposure triangle and what you are trying to achieve. It just domes down to the camera making the suggestions or decisions vs me making the decisions. Even in Shutter or Aperture mode I am going to use my knowledge and intent to set the Shutter or Aperture for the camera to use. The camera is then just using the light meter to select the remaining component.

Video is somewhat like live view...or mirror lockup. It is just grabbing the sensor data many many times...not using the shutter each frame.

Just curious and so asking a really dumb, un-informed question. When taking a video with a DSLR is the camera actually making hundreds or thousands of shutter clicks to capture the video? Hence, shortening the life of the shutter?

Jerry, I think the OP is looking for the design/tested shutter life, not the actual shutter actuation data.
But you as usual have provided a lot of good links to actual shutter count information...
