capss兄，這樣說來和機身防抖無關了？若是這樣，為什麽大部分的C/N的老頭在他們的FF機身都可以照常使用？即使FA31也一樣在5D上有靚眼的表現。

恐怕这才是真正的原因...

这个无知转贴狂武汉爱帝又出来找抽了,看来他很爱装犊子啊.

老鏡頭的分辨率
都遠高過數位鏡

但數位機身有低通鏡片
分辨率被限制在低水平
銳度更是分辨率高扣越多

所以新鏡的數碼優化
是分辨率只提高到某程度
在這範圍內努力提升銳度
因此經過低通鏡片的損失少

如果PENTAX的FF象D700那样做1200w像素，肯定很多镜头都好用。但是K20D和K-7都不止1200w了，所以FF只会做得更高了。。。。。

锐度倒不一定，毕竟不是每家的镜头都以锐著称。重要的是很多135老镜头的分辨率达不到2000w以上像素的要求。
曾经有一段时间的传说是，p本家只有31和fa*85的分辨率能满足这个级别的要求，呵呵。不过那只是传说

传闻是机身防抖技术要求全副镜头的成像圈比胶片时代更大，所以.....

还是呼叫capss大侠吧，哈哈

正常，美能达的神头35/1.4G也是一样的。

说老镜头不能用,
才能忽悠大家买新镜头啊.
不过胶片的成像还原原理和数码是非常不同的.
就锐度来说, 老胶片镜头的确比不上同级别的数码镜头有差.

估计还有光线投射角度的问题, 角度太小的话, 在ccd/cmos上会有暗角.

不过lz很有标题党的风范啊.

现在宾得的机器都说机身防抖的设计，这在胶片机时代是不存在的事情。
这样的设计对镜头成像圈的要求和胶片时代的全副镜头是不同的，所以在有成熟的产品出来之前，现在能覆盖全画幅成像圈的镜头是否能适用，确实是个未知数。
而如果采用镜头防抖，那就是另一条技术路线了，不知道宾得会不会用？（个人认为不可能，不然现在的aps上就会用了）
宾得公司从技术角度给出了现阶段能给出的最可靠的答复，是对用户投入负责的态度。LZ缺乏认真考证就在这里忽悠，明摆的是自己无知还跑出来招摇。

"In our case, if we developed a full frame camera, it's likely that very few of our recent DA lenses (those designed for APS-C) would be able to properly fill the viewing area of this new sensor. And although we have some wonderful FA lenses, like my favorite FA 31mm Limited, I'm not sure even this lens would be up to the optical challenge."

Ned Bunnell once mentioned in his blog that part of the reason why Pentax hasn't released a 24x36mm DSLR is because the few FA/DFA lenses that are still being manufactured may not be good enough for 24x36mm digital. He said he wasn't sure if even the 31/1.8 Limited would be good enough. I thought that was quite an amazing statement. The folks who own Canon and Nikon 24x36mm DSLRs are all happily using lenses that are vastly inferior to the 31, and yet they don't seem to have many complaints. Is Mr. Bunnell really saying that the $100 Nikon 50/1.8 delivers superior image quality on 24x36mm digital than the $900 31/1.8 would be able to deliver? That certainly seemed to be the gist of it. I don't buy it for one minute, but I was rather astounded that he said it.
