Hi, my question is when a lens length is say 200mm does it require 1/200th + shutter speed or does the 35mm equivalent lens length of 300mm mean that it has to 1/300+ to ensure a shake free shot.
Not counting any I.S of course, Thanks

The "reciprocal of the focal length" meme is just a swag. It varies with user technique, crop factor, number of pixels in your sensor, and how picky you are about such things anyway. It really doesn't make much sense to over-interpret it AFAICS.

It's a Rule of Thumb based on experience with 35mm film SLRs. When applying it to APS-C dSLRs, you should use the 35mm equivalent focal length. There are a number of factors that affect the reliability of the premise, not the least of which is technique.
Of course, the use of image stabilization technology makes its application superfluous.

G'day eve
TC above is pretty much on-the-button here > and it does depend upon so many variables there's no clear answer The 'however' comes along as - Q: is it windy? - do you have any body-shakes? - how heavy is the camera & lens combo? - etc etc I find that I can hand-hold my Fuji X-s1 over its 400- 600mm max lens zoom, down to 1/4second ... provided I use 'burst' mode and after taking 3-4-5 images, I then look very-very carefully to select the best of the bunch. Using burst means that the 1st image is often blurred a bit via the very-gentle pressing of the shutter > after then I am just hand-holding and letting the camera do the hard work I can post some images if you wish... Regards, Phil

I think one thing often overlooked with regards zoom/shutter speeds is your subject matter...
If your subjects are moving around quickly,you'll need a FAST shutter speed- regardless of focal length...! |

True. There are two types of motion blur:
But I believe that since the OP referred to a presumed relationship between zoom length and shutter speed, I believe it's the camera shake he/she is referring to.

Thanks for the replies and yes I was wondering about lens shake .
TCav gave me the answer I was looking for in his first reply. Sorry for any confusion there.
