Have you ever noticed that the displaying of viewfinder is different when you change that lens? Brightness is slightly different (sometimes are bright while others dim). The reason is the aperture, the maximum aperture. This is the real shooting of Nikon D700. The lenses are F1.4, F2.8, F4, and F5.6. We can find that after equip with the big number of maximum aperture, the scene in the viewfinder is also brightest. Meanwhile, some photographers claim that the definition and virtual properties of the lens are also doing affect to the observing effect. You can see the parameter on the lens like 18-55mm F3.5 – 5.6, which represent that the aperture is F3.5 at 18mm end while F5.6 at the other end. This number represent of the brightness in the viewfinder. There is a depth of field preview button on the camera body. After pressing down the button, the viewfinder will become dim, but you can handle the depth of field status by doing this. For example, it would be much brighter if there is a “50mm F1.4” lens. Otherwise, if you load on the lens 18-250 mm F3.5 – 6.3 and adjust to 250mm, the aperture will become F6.3, which will much dimmer than F1.4. However, don’t misunderstand that the shoot out of photos are also dim or bight. It is not like that. Compare the observing effect and real photos, you will find that there is difference in depth of field, which means the one of viewfinder can be only as reference. This is also one of the reasons that I told you don’t delete any photos by browsing on your camera. We said that the brightness is determined by the maximum aperture, but when you set is as F11 at the mode of AE, it won’t be dim. The brightness is the status of full aperture, so even the aperture is decreased to F22, the brightness is the same. Then, how to ensure the status of aperture shrinking? Press down the button of depth of field preview. You can also ensure the virtual status by doing this.

Especially at dawn or other dim environments, it is not only brighter, but also easier for handling the focusing range. Recently, for the appearance of Live View functions, the quality of viewfinder is less concerned. However, a convenient and bright viewfinder can bring some funny to you in photography.
