I am shooting wide open with the
Micro‑Nikkor Macro 60mm f/2.8 D lens. Now since I am as close as the lens will let me focus, which gives me a 1:1 ratio the ƒ-number gets bigger due to the lens extending and actually getting further from the sensor.

This is as close as I can focus the Sigma 35mm ƒ/1.4 DG Art lens [11.81"] of the same Christmas ornament.

Here is another Christmas ornament for comparison.

Notice how much Charlie Brown's sister Sally is out of focus at ƒ/4.8 vs ƒ/1.4 in the two photos. The depth-of-field is even more shallow in the closer photo. This is because how close you are to the subject has as much impact on depth-of-field as your aperture.

In this Citadel Christmas ornament you can see how super shallow depth-of-field is at ƒ/4.8 as compared to the photo with the Sigma 35mm ƒ/1.4 below.

Now just to let you see how your distance impacts the depth-of-field here I just backed up just a hair in the lower photo of the ornament with the Micro‑Nikkor Macro 60mm f/2.8 D.

Since I backed up the aperture opened up a little, so you would think the depth-of-field would shrink but just the opposite happened. Again this is due to the distance to the subject.
You want silky smooth BOKEH? GET CLOSER!!!

All comments are reviewed.This is done primarily to eliminate spamming. Please be patient, I maybe on assignment and unable to review right away.
But to increase meaningful conversation, sometimes it’s necessary to reduce the not-so-meaningful bits. Here are the kinds of things we’ve been deleting in recent posts. Please avoid these types of comments:
One-word comments like “Cool!” or “Thanks!” While we appreciate the congrats, we’d love to hear more about what exactly you love, and (even more importantly) why.
Shameless self-promotion. Comments that contain links to your site within the body or otherwise encourage folks to visit your blog are a no-no. If you’d like to increase traffic to your blog, there are other places than here to do that.
Multiple comments by one author. We’re glad you want to be engaged, but please give others a chance to speak, too.
Really long comments. Let’s just say that if you need to take more than three breaths to read your comment, it’s probably too long.
