Original post >>>>
Got the new super high F-stop lens in this morning and had to try her out! Of course, my willing "victim" was my cat Senna.. Question though: on a shot like this, how do you focus on both eyes if you are right ontop of the subject? I kinda got her left eye instead of both eyes. Help! Thanks in advance!

Depth of field is what it is. If you can't be square with your subject, better stop down.

Thanks Zemlin! Yep, the above shot was at 1.8, just wanted to see how it would turn out, now that I'm out of "4.5" range

I'm not to sure you even got the one eye in perfect focus. What F stop did you use, 1.4, 1.8? I'm also wondering what your focal length was that you used?

Not everyone believe in this concept but I have read more than enough posting that show when you use the 1/3 ISO stops rather than the full stops it adds more noise to your image. I certainly changed my camera to full ISO stops only.

Depth of field is pretty much a matter of taste. Like so many other elements in the photographic process its simple to create a failure in original intent and re-name it a success in an unintended outcome.

Depth of field can control how the photographer isolates the subject from the background or certain elements of the subject from other elements. I prefer to decide what constitutes the focal point and keep everything that makes up the focal point in the focus range. I'm not a fan of portraits, for example, where portions of the face are out of focus and the eyes alone are sharp. When the eyes make up only a tiny percentage of the entire picture surface then to have them as the only part of the picture in focus makes the picture as a whole look out of focus.

There are a number of approaches to working with depth of field. One is keeping everything that's supposed to be in focus on the same focal plane (same distance to the film plane) or stopping the lens down to increase the depth.

Extremely shallow or long depth of fields are both interesting and can be used with excellent results when properly used.

Steve
