我巳五年多没用胶片了,冲印质量下降,有些快沖店干脆取消了,当然冲印成大照片的反轉片真爽,回忆这美好时代了,胶片机大中小还有数十,过期胶卷更多了,,,

G90前几天拍的

m4/3 2x就是画面裁剪，和真正中长焦还不太一样

G90 前几天試鏡片..................[oldmanand 编辑于 2009-12-08 11:51]

不过,在无法用接环介决的前提下,可改－个G21当标头也不錯,但M口也只能用在2x上不可用在ff-1.6x数码上,Leica例外,而这改口成本可能很高,似乎就利用鏡片了....

續上今天G90mmf2.8片片[oldmanand 编辑于 2009-12-08 11:27]

很好!求同存异吧,各种把G头可使用於数码的方案均极珍贵,可以邦助G头闲置的攝友,非常欢迎类似信息.....

G头都可以改成M口，改口时去掉AF驱动装置及外壳，然后加入手动对焦环，看起来如同老缩头镜一样[olala 编辑于 2009-12-08 10:59]

视角的丧失已经注定一切了，赚长焦这种事不可深究，求同存异吧

G45mmf2 的人象和芭比G90[oldmanand 编辑于 2009-12-08 05:05]

您的观点我很难苟同,m4/3 2x对广角不利对中长焦有很大优越性,FF机身用180 f2.8的人不少,而很难找到－个色彩象质能和G90相比美的鏡头,实且上G90是目前可轉接到数码上的三个规格中35mmf2 45mmf2 90mmf2.8最好用的一个头,人象,花卉,静物极易出好片,
正因为面积小,更需用优质头,而且只用了优质头的中心画面,目前在M4/3机上用手动头均多数是同时拥有中高級单反及AF头的人,图其小巧轻便而作为备机,而这些攝友,不大会接受M4/3 AF头的色彩和象质,因而將LM CONTAX G ZF ZM 等优质头用到了 M4/3机上,所出片子絶不会过於低於用任何中高級单反AF头,上＝G90mm試鏡片..

我倒觉得G90才好用，上哪找这么便宜又小巧的180/2.8啊，还是菜丝的。



G头是自动头，没有对焦环。转接环通过一个小拨轮进行手动对焦。光圈环在镜身上，手感很好。

我问一个菜点的问题啊，不许笑话我这个冒牌资深啊：contax G头有手动对焦环么？我真的没摸过实物，净看他躺在商家的柜子里了，也没动过心思。G头的光圈和对焦环都是在镜身上么？不会是像某些CN的低档镜头那样没有光圈环或者没有对焦环吧。

我明白，所以我才没有马上进ZM25。
给兄看一段文字：

———————————
Zeiss ZF Color rendition, flare control
The ZF line offers a color balance which is generally warmer (more yellow and a touch of magenta) than most Canon and Nikon and Leica lenses. The ZF line is warmer than even the Leica 90/2 APO-Summicron-R and 180/2.8 APO-Elmarit-R and the Voigtlander 180/2.8 APO. However, it’s more complicated than that—after working with the ZF lens line for over a year, there can be no doubt whatsoever that the color of the ZF lens line is the most pleasing ever encountered by this reviewer. The ZF lenses consistently produce images which are gorgeous. Adjusting color temperature in RAW-file processing for the other brands (even Leica) does not produce the same pleasing result as the ZF lenses; it’s about an entire tonal rendition, not a simple white balance issue. Color is quite simply the most natural and pleasing this author has ever seen. However, the new “nano crystal” coatings offered by Nikon do bridge the gap somewhat.

zeiss确实要比其他镜头更偏黄一些，我个人是非常喜欢sony黄的，所以也非常喜欢Zeiss黄。
另外关于bokeh，刚才的网页下边一点也有两句评论：
————————————————————————
Bokeh, or the way a lens “draws” out-of-focus areas, is a highly-subjective area in which there is some disagreement. There are lenses with truly ugly bokeh, but in most cases, it’s like arguing whether chocolate ice cream is better than vanilla! The Zeiss ZF 100/2 Makro-Planar offers perhaps the most pleasing bokeh available today (see below).

Bokeh is nothing short of stunning with the ARRI optics design of the ZF 100/2 Makro-Planar

Too many photographers seem to think that “good bokeh” means that flat “erased” look seen in many Canon and Nikon designs. The Zeiss designs are different. Better? That’s personal preference, but this author has come to favor the Zeiss rendition over the (numerous) Canon and Nikon lenses at his disposal.

——————————————————
Zeiss的bokeh一直是我享受的主要部分之一，在Zeiss的产品注册栏里，有一个调查，主要购买Zeiss镜头的原因，其中一项就是Zeiss特殊的bokeh，我个人对我自己的contax sonnar85/2.8的散景就超级满意，这也是我决不能把它贱卖的主要原因之一，以后绝对给他配一个全副机身专拍人像，那时候出门的话，ZF100估计就得有段时间在家里歇着了。再给sonnar85/2.8配一个小广角的搭档，俩小机器出门，应该挺爽sonnar85/2.8的清晰度也不错，但比起ZF100确实还有差距，主要在色散上确实不在一条线上，但拍人像我甚至觉得和ZF100可以有替代关系。颜色不错，一点都不差。
