Panasonic Lumix Camera Review

For digital Slr Camera enter-level users, face the camera lenses is often confused. Not to mention the brand and type of the Lens is more than the digital Slr body, the Lens is a variety of sizes and models, I often heard man told me to complain: I don't understand. So, how to understand a basic data of a Lens? actually we just need to know two data. First It is the focal length, the Second, it is aperture.

the first factor resolve whether it can be taken. For example, a digital Slr Camera bundled lens is a wide-angle lens. Use this lens, you want to narrow the gap between the distant scene is not possible, because its focal length is not enough. As another example, you use a telephoto lens shoot citizen at home, It also is not possible, unless your home is a large villa, a living room a few hundred quadrate meters, in a small space, only the wide-angle lens can be inclusive under the wider perspective.

The gap ,break is different. It resolve whether the photo is good. Large gap ,break lens's gap ,break ordinarily is has a higher quality than smaller gap ,break lens, and the large gap ,break lens, shutting speed in low light or moved conditions (like shooting the car, game, etc.) will get better results. For example, if you have a large gap ,break lens, you can shoot a very natural and soft bokeh portrait photos. If your lens gap ,break is more smaller, You also can shoot photos, but the Photo is not so soft and natural.

Note, the fixed focus lens only have a label of focal and maximum aperture. For example, 50mm/F1.8, It means the focal is 50mm, maximum gap ,break is F1.8. But The zoom lens has a label with two focal length and maximum aperture. For example, Tamron 18-270mm F3.5-6.3, It means than the wide end of focal length is 18mm, maximum gap ,break is F3.5 and the telephoto focal length is 55mm, maximum gap ,break is F5.6.
