紧凑长焦 ?26-520mm focal length 相当之 20X Option 讨教
老上我, 赴猎场有一怪癖 Not shoot Gun, But like to Shoot Camera !
猎伴每每得手以后。回程之中都是质问俺:
”.....老上 你这次拍的如何? ..." , "....又有了什么样的好镜头. 可以拿回去 给朋友,”决斗“ ......."
家人,朋友 也在反复观赏我们连带解释 介绍的回放之中。 一次次分享了“猎奇” 和猎获之乐!
另从经济上来分析。 数码猎场的镜头捕捉。 也让出猎的高额投资, 带来新的欢乐。 保存并且 “增值” 了!
尽管有过多次”失手“, 将最为关键的-----枪击、倒地 之一刹那镜头 耽误, 错过了。 但那数千张随手乱拍的照片。 也为我等 七老,八十一回 动胆不得之际。 再来回味 现在的故事,经历。 留下了宝贵的资料。
目前手里有15倍, 18倍光焦的。感觉是 比普通长焦,体积小 使用方便。尤其在野外。 几乎不可能携带那些 ”正规“ 长变焦的“记者家什”。
现在, 有看到两款”20x Ultra-Zoom digital “ 号称 26 mm 520 mm 相当的。
奥林巴斯SP565

尽管有下面的评价。
Remember, though, that 20x is not as nice as it sounds, because part of the range goes down to wideangle.
The reference point is 50mm: this is the normal view, no zoom, no wide angle.
* Wideangle -- from 50mm to 26mm.
* Zoom -- from 50mm to 520mm.
Thus, the actual magnification is 10.4x (= 520 / 50).
Still, that's pretty good. All those common cameras with their 3x "zooms" provide just 2x, because of the wideangle factor.
Many binoculars enlarge the image by 7x, so this camera dispenses with the need for binocs, and has the added benefit of recording what you see closeup. With one exception: binoculars provide stereoscopic vision, not done by digital cameras.
But this new Olympus is still not as good as camcorders, which now have optical zooms of 35x. How can camcorders do what still cameras cannot? Smaller lens and image size allows for larger zoom ratios.
You can read more about the Olympus SP-570 UltraZoom digital camera at The Imaging Resource. It's just $500; the primary drawback, however, is that it uses xD memory cards, instead of today's standard SD memory cards. Since xD is smaller than SD, you can't even use an adapter to reuse your existing collection of SD cards.
但猎场如战场。 这样的紧凑长焦。 不失为我等 既带枪, 又想带 ”大炮筒“的。 首选。
有道是 300来块银元, 万一摔了,咑坏了。 换回 那些难得好镜头,也值得也!
老上我。 这里倡导: 诸位大侠,您 除了稳,准的点击倒 你那 ”养兵千日, 用在一时“ 的猎物。 也点击下 您精彩珍贵的场面 ,于亲友们 重放, 观赏。与我们大家来个 ”物物交换“。何乐而不为?!
这里, 有有关的20倍光焦数码相机之 介绍。 还希望猎场摄影高手, 不惜指教一二:
