Slowest Shutter speed while shooting handheld? EOS1ds MKIII

John Davis , Aug 16, 2008; 02:37 a.m.

Hello, Since purchasing a new EOS-1ds MarkIII, I have noticed that my images are quite blurry when shooting handheld, at speeds that all other cameras have had no problem with- 1/60th and 1/80th.

In fact, the only time I have gotten tack sharp images is when using strobes. Otherwise, they are at least a little bit soft.

So I am wondering what the slowest shutter speed is for shooting handheld with this camera, and if this is normal, or if there may be some problem with the camera. Thanks!

it all depends on the lens....try a wide angle instead of a 600mm at these speed

Wouldn't it be fun to have a contest to see who can shoot a handheld telephoto lens with no image stabilizer and yet yield a clear image - just like the Olympic Games - with world records (measured by focal lengths) being set each time?

Shooting at 1/50 with a 50mm lens, one will have a higher percentage of "sharp" 100% crops with a 5D than a 1Ds3. I'll leave it to the physics experts to give the technical explanation.

I wonder if the massive resalution of this camera, means you are looking a little to close at the images you are producing with a critical eye. It could also have somthing to do with teh size and wait of your new cam.

Hi John! Remember that rule of the thumb when shooting handheld (1/focal length). It goes something like this... Whatever lens you may be using, always pay attention with WHAT focal length of your lens you're currently using. Say for example, you have a 70-200 mm Lens & you're in the 180mm focal length, that only means that you should not(unless you have a very steady hands to prevent camera shake) shoot below 1/180th.

As Oliver said, but you should also factor in the crop factor of the body. Can't remember where I saw an explanation of this though... I find I can hand-hold a quite a bit slower than 1/(focal length) with my 5D, so I guess I am lucky.

What mixed bag is hidden behind the phrase "all other cameras"? Perhaps a Hassleblad 2 1/4" square (larger format), a Leica M6 (no mirror to add vibration)? Without points of reference the question is not answerable.

I'm not a physics expert but EOS 1Ds Mark III is just heavier :)

I happily blast away with a 1Ds3 at slower shutter speeds (provided that I don't have moving elements in the frame) with not too shabby results, with a variety of reasonable lenses (pretty much everything without IS below 85 mm plus 24-105 IS.) But keep in mind that pretty much anything below 1/150-1/100s handheld is a crap shot in terms of sharpness, IS or not (forget the 1/focal length "rule" - it's nonsense for anything other than RF cameras and in any event it was good only for 6x9 cm enlargements.)
Put the camera on a tripod and test the sharpness using Live View and AF and compare it to the results you are getting handheld: chances are that this is pilot error.
I'm not sure whether or not 1Ds3 requires any special handling, a steady hand always helps a lot with any camera, but for sure it makes pilot errors painfully obvious :-)
