当电子技术的应用已经深入到专业摄影许多领域的时候,大画幅摄影器材(尤其是快门操作系统)
却仍然停留在传统的机械时代。传统快门的精度受到机械控制的限制。举例来说,这些快门在曝光
前,快门叶片都要求是打开的,曝光时需要关闭,这种操作经常导致相机的轻微震动。同样的原因
同样的原因造成多次曝光困难,因为快门震动正是造成影像模糊的原因。

骑士ISS-G2是一个多功能、高技术的快门系统,可以应用在几乎所有的大画幅相机和镜头系统中。
所以,在你的设备中添置新的ISS-G2系统并不需要更新或淘汰你的摄影器材。数字控制技术的意义
在于,你可以更加灵活方便的设定拍摄所需要的快门和光圈。骑士ISS-G2智能电子快门系统代替了
全部复杂繁琐的快门操作。
Horseman ISS, 一个完美的数字摄影解决方案
1. 多次曝光的数字摄影,需要一个绝对稳定静止的拍摄环境。传统机械快门很难做到这一点,但ISS-G2可以。它可以做到绝对稳定,并且非常安静。

2. 如果光圈可以按照1/6档位来调节,你就可以从数字摄影中得到更加优秀的影像。传统机械快门无
法抗衡。并且当对快门进行重复操作的时候,机械快门的操作精度更无法和ISS-G2相提并论。

3. ISS-2的采用了远程线缆的遥控系统,全部功能都可以在你的手中轻松实现。再也不用深长脖子在
耀眼的灯光下来回穿梭。
New Adapter for Phase One and Kodak
飞思数字后背的单次操作适配器(Phase One)
Phase One 数字后背通常需要两次快门动作,第一次激活,第二次曝光。但是,单次快门的操作对
于摄影师来说肯定更加容易和简单。当使用适配器时,这一理想将成为可能。它把骑士ISS-G2和
飞思数字后背连接在一起,在快门释放前激活飞思后背。
自动镜头类型识别

DIAL在快门背面有两个小圆盘,上面各有16个定位(0-F,十六进制)。
当镜头安装在快门控制器上以后,通过它们来选择编号,CPU将根据编号 自动识别出镜头类型。CPU拥有包括最大和最小光圈及设定等信息内容的 数据。在内置存储器中(ROM)存储了目前可得到的绝大部分镜头的相关 数据。例如,按照镜头编码清单为Apo-Sironar-S 5.6/210镜头设定好编号,镜头名称、焦距和最大
光圈等信息将显示在控制器的液晶屏上以便确认。(镜头编码清单随ISS-G2说明书一起销售提供)

内置存储器可储存2个设定值
2组快门和光圈的设定可以储存在内存中,分别有2个按钮来控制,选择其一时,当中储存的数据将
被调用。这种设计的优势在于:假如你需要拍摄一件带有液晶屏的产品,例如一台音响,你需要首
先用闪光灯曝光拍摄音响的主体。但是随后你需要长时间对液晶屏曝光。使用ISS-G2时,你可以方
便的在这两种曝光组合中随时任意切换,极大的提高工作效率。
快门速度
在控制器上,当功能键按下时,快门速度可以按照1/3档或更精确的时间步进调节。在不改变光圈的
前提下(景深),快门速度可以无限制的随时调整。在进行多次曝光时,可以进行多次细微的调节,比
如在每1秒钟的曝光时间内可以调节成1.26或者1.59秒。
显示器
LCD Display 显示,一种清晰的LCD液晶显示器,指示出摄影师需要
了解的全部信息。例如:“OUT OF RANGE"的出错信息,
镜头种类及规格,快门状态"CLOSED,OPEN"等信息。在
曝光过程中,LCD将像信号灯一样在红色、琥珀和绿色中
清楚地指示出快门当前的状态。
光圈的设定
DIAL控制器上最大的旋钮就是用来控制镜头的光圈范围的。通过另一个小旋钮,可以
容易的获得每档光圈中间精确到1/10档位的细致调节范围。从1档、1/2、1/3、1/4、
1/6一直到1/10,六种范围的选择将极大丰富摄影师的选择范围,更精准的曝光。
完全数字控制的电子系统,安静而可靠的操作
CircuitBaseMechanical parts have been reduced to a minimum to obtain the quietest and most reliable operation possible. As the shutter has electronic actuators instead of drive springs, it need not be charged or cocked. This permits multiple exposures in quick succession and without any danger of blurring due to shutter vibrations. Optical sensors replace electrical contacts wherever feasible, for reliable, trouble-free operation.
 
Button operated shutter control
Pressing a button on the control unit is all it takes to control shutter and aperture status: RELEASE, STOP DOWN, CLOSE, etc. There's no longer any need to fidget with the front of the camera every time an adjustment has to be made, because all these controls are operable from the control unit. So you can concentrate on the composition arrangement, focus and field depth adjustment.
Cable shutter release
In addition to the shutter release on the remote control unit, an additional cable release lets the photographer shoot while standing at some distance from the camera.
Automatic shutter closing prevents costly mistakes
By installing the special camera back and cable for the ISS-G2 to Horseman L-Series or to a Sinar, Cambo or Toyo camera, inserting or removing the sheet film holder will automatically close or open the shutter. Shutter control is speedy, and you'll never forget to close the shutter when film is inserted.
Synchronized shooting with more than one camera
The Horseman ISS-G2 lets you synchronize shooting with two or more cameras so you only need a single flash. This features is a great help when you want to have a backup, when you want the same shot on two different kinds of film such as color and black & white or instant or when you want to shoot from two different angles. Shooting on instant film with a second camera will give you an immediate preview or what your final shot will look like.
Gray
In addition to the outstanding features of the original Intelligent Shutter System (ISS), the ISS G2 offers a multitude of new functions and features.

  1. CPU and remote control have been combined into one unit, making it lighter by 40% and more compact by 25%.

  2. The fastest shutter speed is now 1/125 sec in case of #0 and #1 shutters (as opposed to 1/60 sec in previous models).

  3. Aperture setting now has additional 1/4 F-stop increments between the 1/3 and 1/6 steps, giving greater freedom in exposure setting and bracketing.

  4. With the previous model, lens code setting was possible only by means of the rotary code switch on the shutter unit. Now it can be done also through the control unit, which is more practical when a single shutter unit is used with two or more lenses.

  5. A serial interface is incorporated as standard (mini DIN 8P connector). Aperture and shutter may be controlled from the keyboard of a computer through the software supplied with digital camera backs.

  6. Power supply voltage has been increased to 12 V from the previous 6 V. This 12 V power can be obtained from an AC adapter or a variety of camcorder battery packs including the Anton Bauer series, a world standard for professional broadcasters' cameras.
