没有什么数码胶卷.
倒是有一个叫做:APS的系统.用的是特殊的相机和胶卷.估计,你是听说的,又不真切.

怀疑说的是数码后背? 但是不是所有普通相机都可以用的,大多数都用不了,只有专用的相机才可接受。

呵呵!关于有没有的问题,大家开开眼吧!

PMA 2001 show report: Silicon Film<O:p</O:p

Friday, 16 February 2001 04:00 GMT


Silicon Film, after many years of press releases and delays have finally brought working product to a trade show. At PMA Silicon Film finally demonstrated their EFS-1 digital film product (along with various add-ons). Essentially the EFS-1 is a digital insert which replaces film in a normal 35mm camera and records the images digitally.
There are still however several limitations, first of all the unit itself has a built-in capacity for 24 images (64MB) after which time it must be inserted into the E-Box and its contents either transferred to a computer or CompactFlash card. The second limitation is that the relatively small 1.3 megapixel CMOS sensor uses only about 30% of the center of the frame, this means that when looking through the viewfinder you have a small field of view (marked out by a supplied rub-on transfer) which equates to a 2.58x focal length multiplier, thus a 28mm lens becomes 72mm. Lastly it only currently supports certain camera models: Nikon F5, F3, N60/N90 and Canon EOS-1N, EOS-A2, EOS-5.

That said, Silicon Film have brought this product to market and we hope are capable of producing similar devices with larger sensors and more internal capacity (or wireless transfer to storage devices). We were lucky enough to be allowed to take a couple of sample images away from the stand, I'll let you decide for yourself.

Shooting an image writes an RAW file onto the EFS-1 which is then decoded by a Photoshop plugin which performs bayer interpolation, white balance, gamma and exposure compensation.

真是高手,这么难的问题也行,谢谢各位, 尤其左右眼:p

我的相机Nikon60入门级:wink:应该适用,不知道性价比咋样?如果不划算,想买Nikon D70, 那么60怎么办。

左眼瞪右眼 发表于 2005-11-24 23:18

好像没得卖的!:(

这个产品之前一直都处于试验阶段,但是,由于数码科技发展太快,成本和销售价格也一降再降,这样的为传统135相机设计的数码胶卷或后背根本就没有办法争夺市场,所以,这个公司的investment也用完了,后来也停止了该产品的研发和生产。目前,应用于传统相机的数码化产品基本上仅限于中画幅和大画幅相机的数码后背,由于市场不大,产量极少,所以,价格超级恐怖,俺从来也不敢去问,前段时间好像有个同学拿了个中画幅(6x4.5)相机Hasselblad的数码后背的宣传资料给我们看,价格好像是40,000多美金。 :D

其实这样的数码胶卷本身有很多难以解决的问题,尤其是应用在单反相机上面。比如说,取景、测光、快门释放等等,特别是当如果感光元件(CCD或CMOS)不是全尺寸的面积,在不改动本身相机结构、机械和光学性能的前提下,如何有效地解决实际感光面积与全尺寸之间的缩小差,就好像我们说1:1.6之间怎么解决?总之,这东西看起来简单,其实挺麻烦的。

D70或D70s是很不错的相机,值得买,你以前的镜头也都可以用,胶片的机身,作为备用机也不会觉得浪费。其实你没有什么损失,用不着烦恼吧! ;)

停产的东西就没什么讨论的意义了
中副的产品也没那么贵了机身加后背也就30000USD 以下都是PHASE ONE 20P的后背

其实D200出来了不如弄台玩玩
你的F60还是留着吧,国内基本1000左右了本身就是台高级傻瓜不适合学摄影,我也有一台不过马上就换了80
