发帖数: 7269 | 1 今年年中Zeiss宣布生产针对Pentax卡口的ZK系列镜头
当时宣布的只有两个镜头ZK 50/1.4和ZK 85/1.4
不声不响几个月过去，美国市场依旧见不到货色，想要买只能在ebay上面买。
今天做了仔细调查，其实Zeiss的所有ZF镜头都将有ZK相应版本镜头，而且进入生产阶段
，只是上市时间稍微不一样。
所有镜头和已经上市情况如下：
ZK 25/2.8，投产即将上市
ZK 28/2，投产即将上市
ZK 35/2，投产已经上市，ebay上面可以买到，最低价格$735
ZK 50/1.4，投产已经上市，ebay上面可以买到，最低价格$485
ZK 50/2，投产刚上市，ebay上面可以买到，最低价格$963
ZK 85/1.4，投产已经上市，ebay上面可以买到，最低价格$895
ZK 100/2，刚投产
好像感兴趣的不多？ |

发帖数: 4260 | 2 这几天借着ZK的人气看了一眼ZK，又看了一眼原来看过的Click Framework。感觉还是
更喜欢Click Framework的approach。
两者相同点是都是event driven，用java写交互的部分。都有很多components/
controls，用户不用写很多javascript。
不同点之一是Click用一个html file做template，感觉比ZK的zul XML file自然的多，
也容易加入html。ZK zul好像不能加入自己的HTML，感觉除了写RIA，几乎不能做别的
，也许是我还没发现怎么加。
两个都没有直接用过，但是感觉ZK的component做得漂亮一些，还可以支持ExtJS。
Click则不行。
用过的高手有什么见解欢迎谈谈！ |

发帖数: 3271 | 3 Everything is essentially HTML and/or javascript on the client site. ZK just
provides another way to code those messy HTML / javascript.
ZK vs HTML = C++, Java vs Assembly Language. AJAX is just a technology that
smooth up ZK. Off course you can use ZK with HTML. And RIA is just one kind
of Website (it's another useless buzzword to me). Your thinking is like
saying Michael Jordan cannot play high school basketball.

个现象很普遍，还不如索性支持ExtJS好了，毕竟ExtJS或者YUI在界面上花很多时间，

发帖数: 4260 | 6 Correct me if I'm wrong - my understanding of ZK is that it can only be used
to develop RIA, but not web sites. The XML doesn't seem to let you put HTML
in it. So, if I'm not mistaken, the verdict is, ZK is not very useful for
web development. But if your specific need is to develop a RIA, it might be
a good choice. (And do correct me if I'm wrong. I'd be happy to know that ZK
does more than that.)

发帖数: 3271 | 7 Well, whatever you like. But I can tell you every area you said, ZK is much
better than Click, unless you regard them as as HTML generation tools, and
really want to work with the generated HTML code (which is not what ZK meant
to be).
I can understand that people may get nervous when they cannot "see" or
understand what a tool like ZK generate. It's a bit like the first
generation high-level programming languages made punch-card programers
nervous because they cannot see any punch-cards:) |

发帖数: 284 | 8 There are several ways in inscribing html code in ZK. I've been using ZK in
developing web applications(purcument,sale,inventory,production management)
since its begining. The following is an example in writing html directly:
Put what ever html code here, e.g.

You can even mix your html,jsp codes with ZK XML codes, or use JAVA to
dynamically generate both. Read dev guide for m |

the ZE and ZF.2 series in the future. With production of ZK series lenses
for cameras with a K mount set to end in the fall of 2010, some focal
lengths will no longer be available. However, the remaining ZK lenses will
continue to be offered at unchanged prices while stocks last. |

发帖数: 3271 | 11 One thing I don't like ZK is that they make AJAX looks so simple, and even
many cheaply built sites such as 武侠小说 sites are full of crappy AJAX
pages that try to reload something on every mouseover. I really hate that.
As a result, ZK's look and feel is now always giving me a cheap feeling,
although it's not their fault:) |

发帖数: 3271 | 13 ZK is more than that. ZK = Java UI Framework + XML UI Declaration (including
XHTML) + Server Side Script Engine. You can use any script language
including Java itself. If you don't like the default look and feel you can
stylize it yourself using CSS, although most developers, like me, are not
good at that part. |

发帖数: 4260 | 14 Could you be a little specific? I'd like to find out how and where to put my
own HTML. Typically you load a .zul for a zk application but the .zul file
is
an xml file that describes the layout, and zk generates the html content
based
on that. If I want to have my own html elements in the page, where should I
put
it?

发帖数: 4460 | 16 3x for your input.
I just start to touch ZK, but the book said even for
a click button event that hasn't really done anything,
the event will be sent to server side because ZK
takes control of almost everything for clients. That eases
the updating of browser, but that also seems to me a
serious drawback. I guess that is what a framework is, you
manipulate things inside quite well but lose some
flexibility in certain cases? |

发帖数: 3271 | 27 That's because you haven't seen enough websites. AJAX Framework such as ZK
makes things easy and thus create the chance of abuse. For example, infobox
triggered by mouseover is one of the most common abuses. Because every time
it will load something from the server, it can easily become a disaster when
you have many elements on your webpages with this mouseover capability. |

发帖数: 684 | 28 For developers, it boils down to the choice of an HTML centric development
approach or an Ajax centric approach. Conventional web frameworks (Struts,
JSF, Wicket, Webwork...) are all designed for HTML centric development
efforts. While GWT, Echo, ZK are Ajax centric.
In the sense that a web project begins with HTML design, conventional web
frameworks are probably better choices. |

That, ironically, is exactly where all the confusion
comes from. Since the javascript library has to be
downloaded by end users, it is in fact redistribution
of the source code. So then our own javascript libraries
and pages could be considered "dynamically linked" and
forced to be GPL'ed as well.
Feel free to call that FUD - it may very well be,
but we just don't want to take the risk. ZK is good,
but not that good. |

ZK is an ajax framework. The chance is that if you choose an ajax, you

发帖数: 34805 | 37 You worry too much. Scalability is not an issue until

ZK is one of so called stateful component frameworks, components
are rendered on server side. But traditional request-based
frameworks are done this way too. The main advantage of ajax,
is updating only a portion of webpage so that the update can
be fast. Reducing IO isn't as important. That being said, as
long as it's ajax framework, you can still expect less traffic
