Coming to switch to Nikon with Sony buying a kit D7000 + 18-105, I wanted to please me by offering me two solid goals and openness, the 70-200 / 2.8 and 50mm f / 1.4 g I expected a quality to match their prices. Both the 70-200 is a marvel and worth the financial sacrifice (just a little heavy and cumbersome to carry around everywhere, but how accurately and development speed, and what dive!), So that I had 50 mm purchased as the ideal fixed focus was to make (on a APS-C focal length of 50 mm turning into 75 mm, which is attractive with an aperture of f / 1.4) was a big disappointment: Development Lymphatic point not really silent and especially a soft quilted frankly f / 1.4 to f / 2 proper f / 2.8 then disappointing again from f / 4. Reading the reviews of this objective on various sites, it is to be praised for its qualities, is described as "soft", denoting probably a very variable quality manufacturing and a wide disparity in performance depending on model. I probably came across a bad copy, so I returned from Amazon after 30 days of testing, and who repaid me without any difficulty. Congratulations Amazon.
Always Dreaming of a bright fixed focus, I finally bought instead the Nikon 35mm f / 1.8 G which costs only 200 euros and frankly there is no picture (no pun intended) and we for money: Fast, silent and remarkable dive, contrary to what 50mm "high end" which is a big disappointment!
