关于变焦的问题,最好将3x或10X什么的换成对应的35mm相机镜头的变焦范围,然后根据需要选择,通常的35mm相机的镜头变焦范围在28mm~70mm/85mm/105mm均可广角端最好要28mm的,这样在狭小的室内基本上就够用啦,本r人没有太多的数码相机的经验,也正打算购置一台,想麦什么产品可到相关的网站查询,然后根据自己的需要选择适合自己的一款,因为各个厂家的同价位产品都喲各自的优点,关键要看自己要干什么用、这一点很重要。不要单单的说这个好那个好,适合自己的最好。

Minolta Introduces the DiMAGE S414
4.0 Megapixel Compact Digital Camera


  







The DiMAGE S414 takes all the strengths of its predecessor, a 4.1 megapixel CCD, a high-quality Minolta GT 4X optical zoom, CxProcess™, and adds versatile features. The new DiMAGE S414 is a responsive, easy-to-use digital camera that provides the tools necessary for great images.







  



The S414's high-precision electro-optical system is built around a 4.1 megapixel 1/1.8-type interline primary-color CCD with 4.0 million effective pixels for fine high-resolution images. This pixel resolution will produce B4 size 150dpi prints or A5 size photo-quality prints.

Minolta's GT Apochromatic 4X Zoom Lens
The DiMAGE S414's Minolta GT lens is a versatile apochromatic 4X zoom. The fast f/3.0 – f/3.6, eleven-element, nine-group design is equivalent to a 35 – 140mm lens on a 35mm camera. The lens' resolution far exceeds the requirements for a 4.0 megapixel CCD. The 4X optical zoom employs two double-sided aspheric elements and AD (anomalous dispersion) glass to ensure sharp images at all focal lengths.

CxProcess™ and 12-bit A/D Conversion
Minolta's image-processing technology, CxProcess™, guaranties the image from the CCD will faithfully reproduce the scene. CxProcess™ controls sharpness by balancing resolution with acutance. This allows fine detail to be preserved while adding depth to the image. Color is critically controlled to prevent objects from appearing over-saturated while remaining vibrant; the warmth of the human complexion or the rich subtleties of green foliage will be rendered as clearly as they were perceived. Contrast is regulated to bring out a luminous quality in the mid-tones and highlights, as well as to strengthen and enrich the shadows.

The secret to photography is in the details; smooth gradations and fine details bring a photograph to life. The 12bit A/D conversion preserves all the subtleties of the original scene. With billions of colors and 4,096 levels in each color channel, images possess almost lifelike color and detail. This is especially evident in portraiture: smooth complexion, fine hair detail, and vivid eye color.

2.2X Digital Zoom
With a focal range of 7.15mm to 28.6mm, the DiMAGE S414's versatile optical zoom is equivalent to a 35 - 140mm 35mm zoom lens. This lens encompasses the most used focal lengths in photography today. It can range from wide angle for landscapes to telephoto for intimate portraits. DiMAGE S414's digital zoom extends the optical zoom's performance by 2.2 times giving an equivalent a 308mm lens on a 35mm camera. The lens can focus down to 10cm (4in) for close-up photography.

Advanced Functions
Employing the same LSI technology from Minolta's top-of-the-line DiMAGE 7Hi and a 32MB buffer, the S414 is a responsive photographic tool. Whether recording, viewing, or editing images, camera operation is smooth and fluid.

The DiMAGE S414 has been given an array of advanced functions and creative tools to realize your inspiration. The autofocus system incorporates flexible dynamic functions that allow the DiMAGE S414 to perform flawlessly in any situation.

Wide AF makes accurate focusing simple. Within the large focus area are three sensitive AF sensors including a central crosshair sensor; the crosshair sensor guaranties accurate focusing regardless of subject contrast orientation. The camera automatically locates the subject within the wide frames and confirms the point of focus by briefly displaying the active AF sensor. Focus area selection allows photographers to select a spot focus area from a 5-point array; this is an attractive option for specific compositions with off-center subjects. The S414 can also be manually focused.

The controls over exposure are amazing. The DiMAGE S414 has multi-segment and spot metering. Multi-segment metering uses 270 segments to determine exposure. Three exposure modes are available: program, aperture priority, and manual. 15-second bulb exposures can be made in manual exposure. Camera sensitivity can be set to auto or to one of four ISO equivalent levels: 64, 100, 200, or 400. And to ensure the best exposure possible, an automatic three-frame bracket can be made with 0.3, 0.5, of 1.0Ev steps.

The sharpness, contrast, and filter digital effects controls are image-processing tools built into the camera. These functions allow image data to be maximized at the scene. Sharpness accentuates or softens details. Contrast controls the difference between brightness levels; increasing the contrast makes the highlights brighter and the shadows darker. And the new Filter effects make a color image warmer or cooler.

Unique to digital imaging, the DiMAGE S414's real-time histogram shows the luminance distribution of the image before it is captured. Displayed with the live image, the histogram allows the subject brightness and contrast to be evaluated to optimize the camera's exposure and contrast controls.

White balance controls how the camera interprets the color of the ambient lighting. Auto white balance compensates for changes in lighting automatically. Four preset white-balance settings, daylight, cloudy, tungsten, and fluorescent, can be selected for specific light sources. And for critical control over color, the custom setting allows the camera to be calibrated to the lighting conditions at the scene.

The color mode has five options: Natural Color, Vivid Color, black and white, Sepia, and solarization. Natural Color preserves the actual colors of the scene and Vivid Color accentuates them. Black and white creates a neutral monochrome image whereas the new Sepia mode gives the classic appearance of toning in old photographs. Solarization creates a partial reversal of tones and colors in the highlights for creative effects.

The LCD monitor displays active camera settings, exposure information, and warnings. This information can be turned off so that the entire image can be viewed. The DiMAGE S414 has two additional displays for critical composition: grid and scale. Usually found in large-format view cameras, the grid makes aligning the camera with vertical or horizontal elements within the image simple; confirming that the horizon or buildings are straight in landscape or architectural photography is easy. The scale can be used in close-up photography to judge the relative proportions of the subject.

Digital Subject Program Selection
In the past, photographers always had to make time-consuming manual adjustments as the subject and shooting environment changed. Digital Subject Programs allows the camera's exposure, white-balance, and image-processing controls to be optimized for specific scenes and subjects at the press of a button. The six subject programs are available:

· Macro: for close-up photography.
· Portrait: optimized to reproduce warm, soft skin tones and a slight defocusing of the background.
· Landscape: optimized to take sharp images of expansive scenes.
· Night portrait: the flash and ambient exposures are balanced to reveal the night scene behind the subject. This can also be used for night scenery.
· Text: for crisp reproductions of black text or line art on a white background.
· Text & Marco: to reproduce small text or line art.

Continuous Recording, Movie Clips and Voice Memos
The DiMAGE S414 can continuously record still images at a rate of approximately 1.6 frames per second. A ten-second self-timer is available for self-portraits. The optional remote control RC-3 can used to record still images and movie clips from up to 5m (16ft) away.

The DiMAGE S414 is not limited to recording still images. Sixty seconds of digital video with audio can be captured. Voice memo allows up to 15 seconds of audio to be attached to an image when it is captured. The movie clips and audio tracks can be played back in the camera.

The controls and dials are laid out for clear, intuitive operation. The five-way controller array is located next to the LCD monitor and is used for setting camera functions. The LCD monitor is large and bright.

Audio signals are used to make positive confirmation of button settings. A shutter sound effect accompanies the release of the shutter. The audio signals and shutter effects can be set independently to one of two tones or turned off.

The DiMAGE S414's contoured body incorporates a large grip for secure, comfortable hold. This gives the S414 a solid, well-balanced handling of a larger camera while retaining the size of a compact .

The new DiMAGE S414 is a responsive, versatile, easy-to-use camera. With a 4.0 megapixel CCD, a high-quality 4X optical zoom, CxProcess™, and an incredible array of features, the S414 is ready to deliver great pictures.

多谢 GOTON!
正如您所说的适合自己的是最好的,因为我对摄影的知识知道的很少,所以很多关于相机的参数不是很理解。我看了一些的关于相机的网站,技术评论的,或是厂商的,还是因为对摄影的了解少,不能消化。我现在主要在FUJI 3800 和 MINOLTA S414 上犹豫,我也没有什么特殊的要求,想着功能尽量多一点,主要是一般的家庭和风景照,通过使用一端时间,对摄影能有个概念。如方便请点评FUJI 3800 和 MINOLTA S414 这两款机的优缺点。多谢!

另外,顺便说一句,现在COMPUSMART有活动,OLYMPUS C4000 和 EPSON 820 PRINTER捆绑销售,可以获得CAN$150的REBATE。可以在 www.compusmart.com 查询。有兴趣的朋友可以看看。

montrealapple:
以下是FUJI 3800 和 MINOLTA S414 两款的比较:
1。象素:
   FUJI 3800(3.24 million pixels);
   MINOLTA S414(4.0 million)
   就这一点,虽然象素是衡量数码相机的一个主要的指标的,但是根据实际使用而言,如果只是家庭或旅游留影,其实2 million pixels足够,出游的时候考虑到照片数量的问题,或只是将照片存到电脑里,通常的照片有640 x 480 pixels足够。这只不过才30万象素。即使你将照片打印出来,只要不是很大,一般1600 x 1200也够用啦,这不过2 million pixels,
2。变焦范围:
   FUJI 3800相当于35mm相机(38-228mm)
   MINOLTA S414(7.15 – 28.6mm)相当于35mm相机(35 – 140mm)  
   就这一点,当然广角端越小越好,长焦端越大越好。
3。最近摄距:
   两者相差不多,FUJI 3800 稍近一点,
   就这一点,当然越近越好,这样在翻拍照片,或是拍摄杂志上的图片时会得到更好的效果
4。最大光圈:
   FUJI 3800:F 2.8/F 4.8/F 8.2
   MINOLTA S414:f/3.0 – f/3.6
   就这一点,数值越小越好,
5。闪光灯有效范围
   越宽越好,这一点 FUJI 3800较优
6。电池:均为4节碱性电池
7。存储卡,均为16m。
8。外形尺寸和重量:根据个人喜好
通过我对两款相机的比较,但从性能来说,我觉的FUJI 3800除了在象素方面少一点以外,其他性能基本上都比MINOLTA S414好一点。另外从外观来将FUJI 3800显得更专业,而且手感绝对比MINOLTA S414好。拍摄时会增加稳定性。
以上只是基本的一个比较,如果让我选择的话我会选择FUJI 3800这款相机。(FUJI 3800的价位也应该更便宜一点把?)
存数个人观点,进攻参考,欢迎进一步交流。

最终买了FUJI3800,用着感觉挺好,外观和手感都不错。

今天看到镜头上有点灰尘,随手用眼镜布擦了一下,好像镜头表面的什么东西给擦掉了一点,懊悔死了,请教高手,镜头表面的东西是不是增透膜,擦掉了一点,问题大不大?多谢!
