A while back I wanted to find myself an iPhone app where I could reasonably quickly figure out what my depth of field was going to be in a certain situation.

I looked at a few and finally decided on an app called f/8. It’s exactly what I was looking for. It’ll keep an inventory of your gear and what you’ve got equipped at the moment so you can swap stuff in and out, little slider bars to adjust settings and an easy display of what you’re looking at focus-wise. I’ll let the screenshots and description on the site and/or app store do a better job of explaining that but I just wanted to say after testing it out that it’s an awesome tool to have with me and quick and convenient enough to be worth using.

If you’re in need of the same thing, you can check it out at the app store or at the developer’s site.
