Nikon 推出大變焦相機 Coolpix P80

Filed under: 數位相機

變焦要多大才夠，是基本盤3倍，還是5倍呢？現在 Nikon 推出新款大變焦相機，擁有高達 18x 的變焦能力，相當於一顆 27mm 到 486mm 的鏡頭，實在有夠誇張的。不過變焦這麼大，防手振、ISO、光圈這些穩定影像的能力就是重要的參考值，否則光大變焦也沒有意義。

P80 還用到了 NIKKOR 的光學鏡頭[1]，IS0 值也狂拉到 6400，並搭載防反射 2.7吋 LCD。功能上 P80 搭載各種預設模式，不論是家庭溫馨照還是酒醉狗仔照都可輕易捕捉，討厭的紅眼也有降低紅眼功能，現在一般相機都有的臉部偵測功能 P80 也一併具有。

Coolpix P80 要價 399.99 美元，本月就會推出，想要購買高階消費相機的朋友們可以等等這款相機，擊點下面圖庫看 P80 各式角度官方照片：

AMD's Phenom X4 9850 gets pitted against Intel's Core 2 Quad Q9300

Filed under: Desktops

We'd already seen a few early tests of AMD's new top-end Phenom X4 9850 processor, but the folks at Extreme Tech have now taken it upon themselves to see just how well the processor stacks up against Intel's similarly high-end offering, the Core 2 Quad Q9300. As was suggested by those other reviews, however, the AMD falls behind the (admittedly pricier) Intel processor in just about every respect, including its ability to be overclocked. On the upside, however, that lower cost will likely offset the performance issues for many users, and it does still boast "moderate overclockability" and run cooler than the Intel chip. ExtremeTech apparently isn't convinced that AMD's pricing is "sustainable over the long haul" though. For its part, the Q9300 makes the most of its four cores and 45nm manufacturing process, with the only significant downside being that it packs only have the cache of the rest of Intel's quad core line. That wasn't enough to stop it from snagging an impressive 9 out of 10 rating, however, with ExtremeTech declaring it "one of the best price/performance CPUs you can find."
