DOF (Depth-of-field) é mais do que um botão na parte frontal de uma câmera; é um sistema matemático complexo que combina distância focal, distância de focagem e abertura. Muitas lentes modernas SLR/DSLR não possuem mais marcações DOF completas ou precisas. Para ajudar os fotógrafos, esse Guia ExpoImaging ExpoAperture² Depth-of-Field oferece aos usuários uma escala completa, que pode ser lida de forma eficiente em um piscar de olhos.

Para usar o guia, é necessário selecionar o tamanho do sensor/filme - desde um fator de corte digital de 2x até filme de 6x6cm - e, então, uma distância focal que varia entre 15mm e 135mm. A escala compensa os tamanhos variáveis de filme/sensor em relação à abertura selecionada. Quando os parâmetros são escolhidos, o guia retorna uma faixa de aberturas e as áreas correspondentes que serão renderizadas em foco para cada f-stop.

O ExpoAperture² é compacto e cabe facilmente em qualquer bolsa de câmera ou bolso. Esse ExpoAperture² inclui um guia impresso para início rápido, uma bolsa de armazenamento e uma tabela de referência de formato de sensor/filme.

Essa versão do ExpoAperture² é um kit de dois discos que inclui um guia padrão para lentes de 15-135mm e um segundo disco para distâncias focais telefoto de 70-600mm.

Tenha mais controle criativo sobre a profundidade de campo
Determine a configuração de abertura, resultado de profundidade de campo ou distância hiperfocal rapidamente
Desenvolva relações de entendimento intuitivo de profundidade de campo com uso contínuo
Rápido e fácil de usar
Compensa para uma ampla variedade de formatos de sensor e tamanhos de filme

    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.

    Good, but I expected more.

    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.

      I very much enjoy taking photos of flowers. This depth of field guide takes the mystery out choosing the correct focal length and aperture. The instructions are simple to understand. What is there not to like? Nothing!

          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.

                      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 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.

                                  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

                                  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.
