sigma的镜头外涂层可以改改了,那质感真的很雷人

可惜适马动作太慢，等它的x3evil出来不知何年何月了

有一种情况厂家抛弃用户，就是厂家自顾不暇的时候，或者说用户养不起厂家的时候。再坚持下去只能破产

你可以搜索一下3CCD，会找到更多信息。3CCD的摄像机很早就广泛应用了，3CCD架构本身带来的画质提高没什么可怀疑的，但并非所有3CCD的摄像机都是高画质的，毕竟有底端型号。看到某摄像论坛上一个人的签名：“3CCD摄像机不一定是专业的，但是专业的一定是3CCD或3CMOS的！”

如果X3结构没有大的突破，不能解决复杂电路带来的噪点和多层结构带来的偏色问题，3CCD会是方向。如果X3结构有突破，比如有机X3感光元件研发成功，那么3CCD不会被采用，毕竟有着成本，体积/重量，对光学素质干扰等方面的局限性。

关于3CCD我整理过一篇文章进行信息收集，感兴趣可以看一看。

sigma说为了给镜头伸缩问题打个补丁,我们就加了个卡口一劳永逸

上一次相机工业大瘦身发生在1972年的OM-1
这一次发生在2009年的E-P1.....※※就在我们身边悄悄流淌

想想也是，对于按部就班炒冷饭发展的摄影器材领域，去反光板数码相机算是一剂强心针了，对于科技推动而言提供了个很好的发展空间

多亏了听从了三少的建议，现在玩ep-1饼干套还是最好的选择。到用烂了，也该有全副的口袋机了吧？要不aps的？实在不行m43的也行，像理光grd3的体积和操控就好。其他的坚决无视，捂紧口袋。

Is Micro FourThirds Raining on Canon's Parade?  
It's a busy - and exciting - time for FourThirds and Micro FourThirds fans these days. The good news is that it's not going to get quieter for quite a while. As this article hits the press, the technology curve will have just gone a little curvier in Japan. Right this minute, the pace at which Panasonic and Olympus are working to cement their leadership for EVIL cameras is running so fast it's hard to come to terms with.。。。。。
。。。。。
【结论】
And so we have decided to come up with our own observations as to what we can see is happening and what we may be able to expect within a shorter frame of time:



Canon’s lower market response

Canon will persist on two fronts as a collective response. On the lower front, they will further develop their Powershot G- and SX-series (eg SX20 IS) and incorporate high-definition movie recording functionality. They will also expand movie functionality to their compact camera ranges in a bid to cover their bases at the consumer end of the market. The idea is to inundate the market with a bigger presence to outdo Micro FourThirds.


Canon’s higher market response

On the DSLR front, Canon has already begun to incorporate movie functionality with their EOS line, beginning with the 500D (Mar 25 2009), 7D (Sept 1 2009), 1D Mark IV (Oct 20 2009) and 550D (Feb 8 2010) and it will not stop there. The aim is to block Micro FourThirds from making advances into the DSLR segment.


Powershot’s competitiveness against Micro FourThirds

The problem with Canon’s strategy in the lower market segment is that these are not lens-interchangeable cameras. Therefore they may still lack the right package to compete. Unless Canon grafts their premium APS-C sized sensors, Micro FourThirds will also eventually out-resolve them also.


EOS’ competitiveness against Micro FourThirds

If the customer moves to their DSLR segment, they will find high-definition movie functionality but Micro FourThirds beat them in terms of sheer size, bulk, weight and friendliness. The problem here is that Canon’s DSLR and lens designs are so locked together that if they were to produce a Micro FourThirds competitor, something has to go. Because the larger lens mount won’t help them to downsize, there is only so much that Canon can actually do.


Nikon’s lower market response

Like Canon, Nikon’s plans are similar. Lower-end consumer cameras like the Coolpix S4000 and S8000 (both Feb 3 2010) now come with movie-recording capabilities but Nikon does not exactly have a matching Powershot G-series competitor. In a game of catch-up, this is where Nikon is finding itself in any segment not covered by their DSLR range.


Nikon’s higher market response

Nikon’s strategy with its DSLR cameras apes Canon. Movie-recording capability is now available in the D300S (Jul 30 2009) but interestingly not the D3000 announced on the same day. On the other hand the slightly higher ranked D5000 (Apr 14 2009) has just as the D3S (Oct 14 2009) also has, which replaces the D3X (Dec 1 2008).


Coolpix’s competitiveness against Micro FourThirds

Neither the Coolpix S4000 nor S8000 are positioned competitively against anything that Micro FourThirds offers today or in the future. Being lesser than Canon’s Powershot G-series, they are lesser featured and there is no interchangeable lens capabilities. These cameras are not likely to offer viable alternatives to those who are looking for DSLR-type features and performance but in a small footprint. That’s where Micro FourThirds is at.


D-series’ competitiveness against Micro FourThirds

Nikon’s offering of movie-recording functionality within its DSLR range is confusing. While Canon has spread it across higher and lower-end DSLR models, Nikon has chosen to fit it to its more premium cameras, leaving only the D5000. Even the D3000 lacks this feature, leaving it difficult to compete directly with any of Micro FourThirds’ models.


Lens limitation problem with tied up resources

Both Canon and Nikon have a lot tied in to their complex range of lenses. With various compatibility issues sharing the same lens mount and having to maintain them to suit their myriad DSLR models then and now, it is difficult to see how they can pour more resources to developing yet another line of ultra-compact lenses to build around a brand new competitor against Micro FourThirds.


A new camera will cannibalise the G-series

It just doesn’t make a lot of sense that is, unless Canon, with its huge resources, decides to take a wholesale plunge and create a new camera line. That would justify a whole new range of supporting optics but this may also mean the possible cannibalisation of its Powershot G-series. Furthermore discontinuing the G-series will likely cause uproar in a market filled with dedicated loyalists. To say the least, this is a difficult conundrum to deal with.


Cultural problems with downsizing

From a historical perspective, both companies have a collective corporate culture that does not seem to embrace camera downsizing. Form factors have remained on the large side ever since Olympus failed to make an early move in the DSLR segment and even then, efforts to make smaller cameras have been a little lame. Time will tell if they are compelled to change but that would mean following rather than leading the market – not something they are keen to be seen to be doing.


Not much time to hesitate

Canon as much as Nikon may be choosing to wait and see how the market pans out with Micro FourThirds but time may not be on their hands to do this any longer. With Ricoh and Samsung already out with their versions, there is also Sony rumoured to be on the brink of releasing theirs. There are also claims that Fujifilm may be joining Micro FourThirds and is in final preparations to announce their version. These are exciting times for the industry but they will add further pressure to the two companies to come out with an appropriate response.  


A possibly resurgent Pentax

Pentax, whose DSLR sales have not been the best, have seen better days during the film era. And of all the traditional companies, Pentax has the least to lose in developing a similar camera to compete against Micro FourThirds. They are not encumbered with a huge line-up of lenses the way Canon and Nikon is. Their DSLR sales are flagging and there appears to be strife internally. So the possibility seems good to go for Pentax.


After six models, Micro FourThirds promises plenty of action and some of these are destined to shake up the market. 2010 and 2011 are the immediate years to watch this new platform mature. Olympus understands that this is a splendid opportunity to disrupt the current market leadership that appears in disarray if not indecision. Panasonic, after years of seeing their FourThirds efforts humbled, is actively adding more daylight between it and Sony. As personal as this fight tends to be, Micro FourThirds offers Panasonic tremendous traction in a resurgent market.



In 1972 the OM-1 rewrote the rules for SLR cameras. 38 years on, Micro FourThirds could do even much more than that.

松下既然主打EVIL，想来感光器也会对此有所准备。效果嘛，等大家把实机都拿出来后才能知道。
用3MOS感光器的机身必定不会太小，起码现在EP-x和GF-x肯定是不行。高感光不见得会是APS-C占优，当年感光面积大了60%的A100高感也未见得比E510好到哪去，主要还是看各家的提高信噪比功夫是否到家。
我觉得Sony用APS-C，先天就在镜头尺寸上吃亏，机身防抖的空间安排会更紧张以至于难以加上，尽管得到了感光面积更大的好处，有所得必有所失。这类跨界EVIL，不是为了取代专业机的，体积和像质必须达到良好的折衷。

这样机是低挡普及型,连防抖也不配备,nx10出手高多了,从目前看到的片片,nx10相当不错,如能换用上高挡头值得玩玩,这个我想上市时会有极大不同,可能外型和配备均会有所提升,到时再看看吧...

晚上下班回去的时候随手照的，用的八爪脚架
暗处对焦那可是相当犹豫啊~松下的这几个变焦貌似都有鬼影和眩光

本来，我也想“整”一个折腾一下，结果，没有大的改进，都三代dp产品了。关键---据说容易坏。

不过，看4-3网的“猫兄”拍的到是很漂亮的。不知道他如何忍耐蜗牛般的AF。

看来 一介还是要半幅的？
m43与半幅能差多少？
iso400以下，估计差不多吧？体积小，好玩呢！

你拍的这张ep-2的照片，始终在我电脑中。

工地。再练拼盘。忘了上图，麻烦三少删了吧。
