The tests and opinions buyer for Alpha 57 have but then led me into temptation and I switched from Nikon to Sony. Preliminary exchange was fully worth it! Although I was pleased with Nikon, but missed but in many situations, the folding screen and the built-in stabilizer. The technical values of the Alpha 57 I do not need herunterleiern which everyone can easily read. For conclusion: The case feels high-quality, which is not true for all Alpha models. The grip is very good sized, the housing sufficient for my hands. Since I can spare a battery grip once. The display is excellent and provides even in sunlight a very good picture. The sensor switches to the viewfinder can be very good use, the viewfinder itself is more than adequate. The built-in flash brings good illumination. But as I often reach back to the hot and must come through the hood, I looked for a good 200 to Nissin Mark gegönnt- highly recommended! In ISO range I'm basically just to 800 because noise does not matter. The operation of the buttons and settings, and menu navigation are easy to learn. The continuous shooting speed is excellent and has already brought me a few nice shots. On GPS I can do without, I've never used. Who disagrees here, you should look at the more expensive sister models. The autofocus is fast and accurate. The color rendering is very natural. One should only buy housing. The two offered set-lenses can not reproduce the optical performance of the Alpha 57. For the wide angle there is a good or Tamron 16-50 2.8 from Sony. If you like photographed Portraits, the Zeiss 85mm 1.4 should view. While it pulls quite a hole in your wallet, but rewarded with an unprecedented quality. For the telephoto range can very well use the Sigma 70-200. From f 4 it delivers very good images. When choosing a flash I have for Nissin decisiveness a purchase that is worth every euro. If one adds up the equipment, already a penny comes together. You will be rewarded with a lot of joy when photographing and excellent pictures.
