I do not know the term used to discribe my question. Does any one know the apature on the 70-200mm, 85mm1.4, 17-55mm where everything is in focus. For example, when shooting landscapes the whole depth of field is in focus? Is there such an apature or does it vary with each shot.

I am traveling to vegas on monday with the wife and while she is working I'm headed off to the Grand Canyon, Hoover Dam, and possibly Death Valley. I'm bringing all of the lens' listed below.


Thanks,
Larry

You mean hyperfocal distance. This is the distance setting, D, specific for each focal length *and* aperture which has depth-of-field extending from D/2 to infinity.

Lenses used to have colour-coded marking for the hyperfocal settings, but they mostly are gone with the onslaught of AF. You can search on the net for DOF calculators, though.

bjorn, gave you the correct answer

may i attempt to make it easier or simple

if you want less dof use larger apertures

if you want more use smaller apertures

i would look up a dof chart on the web, just google

depth of field

love your trip, have a good time

Bjorn thanks for the explanation. I could not think of the term to do a search.

Mark thanks for the example. I know about the apatures and DOF. I was just wondering if there is a specific one best for a lens.

Thanks again,
Larry

larry, dof only affects the relationship of your subject to the rest of the photo

it is really what you want to see

you may be thinking of at what aperture will i get the best focus and sharpest image

this is different than dof

you are using three really great lens

if you shoot those lens and almost any aperture, your results will be terrific.

it really depends on your ability

I was talking about the hyperfocal distance. I found a cool little calculator. This is the explanation it gave:
"The Hyper Focal Distance is the focus point, such that anything between half the distance to the focus point and infinity is in focus. So, for example, if for a given film format, focal length lense and f-stop the hyper focal distance is 6 feet, if you focus the camera at 6 feet, everything between 3 feet and infinity will be in focus. That is how you get the neat pictures of a small rock in the near foreground to be in focus, while the beautiful mountains in the background are also sharp."

It will be a little challange for me out there in the bright sunlight. I am used to taking pictures of dance recitals and competitions.

"everything between 3 feet and infinity will be in focus" - should be "everything between 3 feet and infinity will be reasonably sharp". :)
