I saw it on the Expo Imaging website and decided to try it.
The manual states it is compatible with 35mm/FullFrame digital, Non-fullframe digital and medium format.
Can calculate DOF for focal lengths ranging from 24-135mm with no calculations required. Outside this range is possible is possible, but some math is required. (Need to do some multiplication/division of distances etc)
Is capable of working less than 12", but again some math is required.
The device itself is a fairly sturdy construction made of 2 layers of platic, one which rotates over the other. It is about 3.125" in diameter
On the back of the Large disk is the Zone Dial. This has distances marked from 2' out to infinity. This is where you would select the range you want in focus.
On the other side is where you set your focal length. Once set you can read of the suggested aperture for the distance range you selected on the Zone Dial
Having done some minimal testing indoors, it appears to work fairly well. Admitedly I have done no real scientific measurements etc. but so far things look pretty acurate. Maybe if the good weather holds up I will et out and try some real distances and see how it fares
The manual is a well put together document detaling the use of the ExpoAperture. good clear diagrams show how to use it for all the focal lengths etc supported. The manual is also available to download from their site http://www.expoimaging.net/support/manuals/EN_6.pdf
The manual and the disc all come in a waller that helps protect the disc from scratching etc, and is small enough to fit in most camera bag pockets etc
Overall I am happy with the device so far. I have used PDA software to do DOF calculations etc, but that was never optimal (the battery was always dead when I wanted to us it most :rofl ) but this is easier to use than those were and needs no power supply (how many new gadgets can we say that about?
I personally would have preffered something a little larger, but that is just my opinion. The math, while not overly complex could hinder some people, but its not enough to stop me.
Check out the manual, see what you think. Personally I think it will be worth the $20 I paid
