It is easy to learn how to use and then operate these Depth Of Field Guides. The one caveat is you must be able to accurately judge distances to your focal point before you can use any Depth of field guide

This a really neat gadget. When I saw it at first I was not sure how useful it would be but I have used it and it is very accurate in determining the depth of field for any distance and camera. No more guessing. I got the 2 disk set even though I only use one for the lenses I have but the price of the two was cheaper than getting just one. I keep the set in my camera bag at all times. I recommend this product.

Depth-of-field has been somewhat of a mystery to a degree and this is an excellent tool to determined your depth of field for the lenses you are using. I use this primarily to study the Depth-of-fields for many scenarios to better prepare myself when I go out to the field to shoot.

Yes there is only a quick get started guide, but if you understand the concepts of DOF it's all you need. It's small enough to easily carry anywhere, well built, easy to use.

A little cumbersome to use, and would like to see area in front of and behind focus point, and info on DOF at micro distances. Still useful, and a good product.

Very simple to use tool to calculate Depth of Field. Within 5 minutes able to use the disc to calculate required aperature across variety of desired focal distances and ranges.

Only takes seconds to decide depth of field that best suits photo composition. If you have a moment to decipher your best composition you cant't go wrong with this product. Only con would be once you set the wheel you must grasp firmly with thumb and index finger or you will lose your setting; however, that's not so bad once you get used to it.

I received the product today and discovered that there was no instructional CD-ROM included, even though the "quickstart guide" refers to the "included cd." I called the company and was informed that they no longer include the disc. Instead the information can be found at their website.

I bought these to help me learn about depth of field, and have found this product easy to use. You have to measure the distance semi accurately which is the only downfall. But if you take the time to be half accurate, or over estimate the distance these will work for you. Much easier to understand than trying to decipher a depth of field table.

this is a great tool for learning and also for having a quick DOF reference. I like the size of the disk as they are small enough to put into my camera bag. I recommend the two disk set as it covers a broader range.

I mostly shoot wildlife. My use of this is as a tool to teach with. I also use it to better prepare myself in anticipation of a shot.

I am new to photography, and this is a very helpful tool. Quality discs wont get damaged or wear out easily. Comes with a clear plastic sleeve for each disc, quick reference, and full instructions on CD-Rom

Comments about ExpoImaging ExpoAperture2 Depth-of-Field Guide (2-Disc Kit):

This product performs four useful functions regarding depth of field and selective focusing: 1. Determines appropriate aperture and distance for desired DOF.
2. Gives appropriate DOF for given aperture and distance.
3. Gives accurate hyperfocal distance for all f/stops on any given lenes and focal factor (film or digital).
4. Gives DOF for closeup photography.
Great because it is easy to use once one gets the hang of it and a great learning tool, as it does as advertised in a general sense.
Needs improvement regarding it's precision in measurement indications on the dial.
