Photojournalists have a saying, "f/8 and be there," meaning that being on the scene is more important than worrying about technical details. Yet with f/8, the depth-of-field and hyperfocal distance calculator for the iPhone and iPod touch, youll be there with the depth of field spot-on, too! Anywhere, anytime!

With f/8, all parameters and values are shown on a single screen with no scrolling required. All calculations are performed interactively in real time for maximum efficiency. The concept of camera bag provides fast access to the bodies, cameras, and lenses regularly used.

f/8 comes with presets for more than 800 camera models from Canon, Casio, Epson, Fujifilm, HP, Kodak, Konica, Kyocera, Leica, Minolta, Nikon, Olympus, Panasonic, Pentax, Ricoh, Samsung, Sigma, and Sony. There are also presets for various film formats (i.e., 35mm, 6x4.5, 6x6, 6x7, 6x9, 4x5, 5x7, 8x10), and cinematographic formats (i.e., 16mm, Super 16, 35mm). Furthermore, by choosing a circle of confusion (and, optionally, built-in lens) directly, camera models currently not listed can be user-defined. For lenses, f/8 allows not only the focal lengths to be specified but also their maximum aperture and minimum focus distance to conveniently adjust the range of input parameter allowed.

NOTE: f/8 does not use or manipulate the camera of the iPhone.

A Big Big Scam

App out of date. Database update at added cost did not add cameras or lenses. No customer support to contact.

Useless App for new equipment

Worst app ever. It came recommended in a photography article but unfortunately I didn’t read the reviews before I paid for this. The app has not been updated since 2011 and does not support any of the new cameras. I own a Nikon D800. This app is totally useless for my equipment.

My go to for DoF

So many of these apps have come and gone, but this one has had the staying power for me as a serious hobbyist photographer. I dig it.

OUTDATED..Out of business??

This app is very out of date and it appears the company/app developer is out of business. I tried to contact them via their ‘Developer Website’ link. On the site it has a Support/Contact us link. However, when I sent an email, I immediately received this reply "Delivery Notification: Delivery has failed”. Don’t make the same mistake I did…my bad. Last update is dated Jan 2011.

Very good EXCEPT

They dont have the 6D! I am using the MarkIII instead, but Id rather have my actual model. Good choice of lenses, has measurements in feet, and is very easy to read. Makes understand DOF relatively simple.

Very Technical

Does what its supposed to do. A few issues: It is not current with cameras. I have the 5D Mark III, which has been out for awhile, yet the app doesnt have it yet. It also is prone to crashing, and tell me a lot of what I already know. I feel the price is a bit much given what it does and the fact that its not up to date with technology (in fact its well over 6 months behind).

2 issues

I totally agree with the other reviewer who said that there are two major issues. The measure of unit is only in meter/centimeter, and the closest focal length is at 4 m
