大凡烧友都希望自己有一副坚如磐石, 轻如羽翼的脚架, 相信脚架的不二选择就是捷信 但是云台呢? 作为脚架和相机链接的关键部件, 地位也是相当重要 最近作了一些RESEARCH, 给大家汇报一下 第一个品牌是来自精密工业制造王国瑞士的 Arca Swiss 看看这些惊人的指标吧（Arca Swiss B1）：承重40.8公斤，净高11.4cm，自重0.77公斤 欧洲货, 质量可靠, 但是价钱贵, 大概要800刀左右一个 购买的网站在这里: http://shop.cameraelectronic.com.au/E5Shop.cgi Arca-Swiss Monoball B1 Ballhead Review For many years, the Arca-Swiss Monoball B1 Ballhead has been the standard by which all other ballheads are judged. Try one - you will quickly know why. Although not inexpensive, the Arca-Swiss Monoball B1 Ballhead delivers on quality. With the exception of a non-captive universal clamp thumbscrew (why not Arca?) - fit, finish and functionality of the B1 are exceptional. One of the Arca-Swiss Monoball B1 Ballhead's differentiators is that it is an aspherical ballhead. As the load on the head is moved away from center, the effects of gravity increase. To offset the higher gravitational effect, tighter tension control is needed. Conventional ballheads require correcting tension control adjustments to be made. The Arca-Swiss Monoball B1 Ballhead, by virtue of its elliptical nature, automatically adjusts to handle the off-center load. The tension automatically gets tighter as you move the load off-center. And it works as advertised. Very nice. Tension adjustment on the Arca-Swiss Monoball B1 Ballhead is via a small thumb-dial on the main friction knob. I really like that it is easy to set but not easy to accidentally change - unlike the Kirk BH-1 Ballhead (below right) which utilizes a separate thumbscrew for tension adjustment.  Another nice feature is the indexed friction control knob. This allows you to know how tight/loose your Arca-Swiss Monoball B1 Ballhead is without having to test it. The 360 degree panning base is also indexed (helpful for panoramic shots). A universal clamp on the Arca-Swiss Monoball B1 Ballhead accepts universal quick-release body plates and lens plates. I like the more-round clamp thumbscrew design of the Arca-Swiss better than the Kirk BH-1 Ballhead's 5-pointed design. It is easier to roll/spin in your fingers The Kirk likes more wrist action to be involved.  Pictured above is the Arca-Swiss Monoball B1 Ballhead mounted on a Gitzo G1327 Carbon Fiber Tripod. Is a 90 lb load rating high enough for you? If so, the Arca-Swiss Monoball B1 Ballhead will handle your equipment weight. I'm not sure I can imagine having 90 lbs mounted on this small 1.7 lb ballhead. Other than keeping it clean, the Arca-Swiss Monoball B1 Ballhead requires no maintenance. It is backed by a 3 year warranty. I keep it in a Lowepro Lens Case 1W when not mounted on a tripod. Overall, I am very pleased with the Arca-Swiss Monoball B1 Ballhead. It is a smooth, refined and solid camera support. [ 本帖最后由 dickson 于 2009-5-2 08:27 编辑 ] |
