DoF on the Canon 500mm f/4.0L

[cmr164]

Note that at close focus (4.5M 14.8') the DoF does not expand much even at f/32

f/4 looks real tight. That will show any mistakes you may make. I would imagine it will take some practice to get the best out of it.

I can't wait to see some shots from this monster.

Well hopefully Rutt and Jimf will join me Fri Feb 11 far some walking around pictures in Davis sq or Harvard Sq. Any other MA based grinners want to join the fun?

Very interesting chart. Did that come with your lens, or did you find it on the internet? Mind sharing the link??:wink

Edit: I just noticed that at f/4 and infinity focus, the near distance is 1.7km!!! I can't believe that is correct, is it?

There's a Harvard Square in the Philippines? What a coincidence.

The Canon Museum (http://www.canon.com/camera-museum/) is just plain cool! The write ups on every EF lens ever is here (http://www.canon.com/camera-museum/camera/lens/f_lens.html).

Bear in mind that they are not using a hyperfocal distance. Figure about a 2 to 1 ratio for DoF in front of vs behind the point of focus. By setting the 'D' at infinity they are tossing the bulk of the DoF out past infinity

Wow, I visit the museum all the time, but I'd never seen those charts before. Thanks! :)
