Protip, when shooting with non-IS lens, try to keep shutter speed faster than lens effective focal lenght. I.e. if shooting with 135mm lens on a Canon x1.6 crop body (making overall focal lenght 216mm), 1/250 is quite safe bet for shutter speed.

And ducks are nice to shoot, before you notice that they are extremely boring in a long run.

Also, when photographying animals, try a faster shutter to 'freeze' the object.

protip: crop factor does not really matter

its always 1/focal lenght.
the crop factor just means you miss some picture out that that lens would have on FF

Exception: when using flash, its possible to have sharp photos with long exposures, as if something is only seen for the duration of the flash, thats as good as a fast shutter speed.

see: high speed photography on the cheap.

you fool, its 1/focal length based on 35mm FILM sensor sizes, So the original statement was true, a 100mm lens in a Nikon DSLR = 150mm.

Also higher MP camera's show camera shake more (more fine detail to be compromised by motion), so a 6mp D50 is a little bit easier to handhold than say a 10mp D40x.

thats rubbish. when you take your 10mp image and resize it down to 6mp...it will be the same - well, better actually.


lets get 1 thing straight.

a 50mm lens is a 50mm lens - on ANY camera.
if you have a 1.5x crop, your sensor then only sees some of what the lens sees.

therefor, its like me saying this

if i shoot at 50mm and 1/50th of a second on a film camera......and then i go and get my film printed.

and then i cut a few cm off each side.....now is my picture less sharp? since i cut the bits off the side......not do i have more shake?

Go figure that out, and get back to me.

Should be
"And then I cut a few cm off each side AND BLOW IT UP TO MATCH THE ORIGINAL SIZE"

And the answer is yes, the shake in the picture will be more noticeable.

So yes, it is indeed the 1/(35mm-equiv focal length) that you should use as a rule of thumb.

The rule of thumb doesn't completely work on digital because crop bodies tend to be made of lighter plastic compared to the metal film bodies around when the rule was made. Then a 50mm lens that's equivalent to 75mm on film is probably lighter and less bulky than a real 75mm lens.

So while>>64240is completely right, these are things you should take into account too.
