Shutter speed rule of thumb and crop factor? (Page 8): Ha! Got there at the same time! Cheers...

kind of like pliers but with a locking grip there is a long screw on one half which limits how far they can open or close also called "vice grips" sorry divided by a common language thats thrown a spanner (wrench) in the works.

A very useful tool, unless you are a mole of course! http://www.wonkeedonkeetools.co.uk/mole-grips/what-are-the-different-types-of-mole-grips/

Not to be confused with a graduated "G Clamp" otherwise known as a micrometer.

Thanks.

Thanks. Now I know.

Now this has really gotten absurd! All this hubbub over a rule of thumb that has very little real world value.

Lighten up.

You are right. If you use the rule, the effective length must be used. But considering new camera high ISO performance, IS on th elens, and the shutter speed required by the situation, I never find myself in a position of needing to use this guideline.

Agree. And of course the rigidity of your stance, and how you hold your camera, your breathing, and other factors come into play. Even though I'm 71, I can still get a high percentage of sharp keepers at slow shutter speeds with unstabilized lenses. Unfortunately, newbies often get confused by these "guidelines" when they get blurred results using them for moving subjects. Most guidelines tend to be very generalized starting points rather than rules to be adhered to. I'm sure that many here can get shots at much slower shutter speeds than the guidelines suggests, and many others, as a result of poor technique or physical limitations, may need a much higher shutter speed.

You REALLY NEED to watch the video that Paulie referenced us to.

Many reputable reviewers, specifically The Digital Picture are starting to recommend 2x focal length for very pixel dense crop cameras such as Canon 80D. The theory being it will take much smaller movements to cross pixels with so many in such a small area.

But does it really matter how many pixels are in the circle of confusion?
