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.

Misleading Product Description and Non Existant Customer Service

F/8s product description led me to believe I was purchasing an APPlication that would add f/stop and shutter speed controls to my iPhone camera. However, this product is only viable for calculation of f/stop and shutter speed for a broad range of digital camera makes and models. Bitwerkz, never responded to my email which described the confusing product description, nor did they provide any explanation to why they could not refund my purchase. ***HORRIBLE CUSTOMER SERVICE*** and ***MEDIOCRE PRODUCT*** ***DO NOT PURCHASE*** PS: I have worked in Film and Photo Production and Advertising for 12 years, and have a BA in Fine Art from FIU.

Very nice!

I like the lay out and ease of use. This is a great tool for certain photographic situations.

dont see any different

anyone know how to use this application wuold u be kind and showing how it works

Good app with great potential

This app is easy to use, and works well for helping with composing landscapes. I wish that it went to smaller apertures (such as f/32) for some of my kit lenses. It would also be nice to be able to select from a database of lenses, or be able to input more lens properties.

Extremely well thought out UI

I was previously using a laminated dof/hyperfocal chart for my 1.6x crop factor digital SLR. When I recently upgraded to a full-frame SLR, I realized I needed a new chart. Fortunately I thought to check the app store for a dof calculator. This app was EXACTLY what I was looking for, and is much, much easier to use in practice than a chart. No mental gymnastics: just tell the app what body, lens, and zoom you are using and then fiddle with the aperture and focus point sliders until you get the hyperfocal point and dof you desire. This UI was clearly designed by a photographer. Very, very nice, and even a couple bucks cheaper than the nice little chart I was using!

Dont buy

I am a A list photographer... This is not what it clams or will give you what a f/8 lens will do. It confused me and I own high end bodies and lens.

The app has potential...

Unfortunately, it has too many bugs an falls short. Dont bother programming in your prime lenses, as the app wont let you adjust the aperture with fixed focal length lenses... for some reason, after I added a prime lens, I ended up with the same problem on all of my other lenses... I currently have 2 DSLR bodies programmed in, along with 2 16mm cine cams and 3 hdv cameras, and none of them calculate properly when paired with any lens since I added my 50mm prime lens... a huge disappointment for 4 bucks, but once this is fixed its so worth the money!
