评测背景

    自从CCD传感器在消费级数码相机领域被CMOS取代以来，关于二者孰优孰劣的争议就从未停息；这两年CCD又被小红书带火了起来，一众CCD相机从电子垃圾变成了香饽饽，CCD到底在成像上有什么特点着实引起了我的兴趣。正好我手上有宾得最早应用CMOS传感器的单反——K20D，而它的前一代产品又正好是宾得曾经最富盛名的产品之一、像素“高达1020W”的CCD单反——K10D，这两台机器又共用基本相同的机身，因此拿K10D和K20D来做CCD&CMOS的对比评测恐怕才合适不过了。 一不做二不休，我立马在海鲜市场淘来了一台成色相当不错的K10D，经过小半个月的使用和拍摄，我决定着手写作此篇简评。本文主要包含外观对比和实拍对比两部分内容。

外观对比

K10D和K20D在外观上基本是一脉相承，K20D只是在细微处做了一丢丢优化，解决了使用上的一些不方便的问题。相机菜单中存在的差异将在实拍对比的开头简要说明（因为懒所以这块我没配图，就用嘴bb一下吧 ，请大家见谅~）

实拍对比

K20D作为K10D的继任机型，在外观上的变动很小，但在功能和菜单上进行了一定的优化升级：

首先K20D是当时像素最高的APSC数码相机，达到1460W像素，K10D则为1020W像素，实拍中K20D所拍照片的裁切空间确实更大一些；其次，K20D在色彩模式上有更多的可玩性，相比K10D只有自然/鲜明两种色彩模式，K20D则包含鲜明、自然、人像、风景、风雅和单色这6种色彩模式，可玩性更高；第三，K20D的“数码滤光镜”种类比K10D增加了“色彩提取”、“插图”、“HDR”三种模式；第四，K20D的连拍速度和张数也得到了升级；最后K10D的快门声音与K20D存在差异，K10D明显更加清脆，K20D的快门声音则有点闷但更轻柔。以上列举的两台相机存在的内在区别只是我在使用中发现的较为明显的不同，很可能还存在其他不明显的差异。

接下来是大量对比图片的展示，所拍摄照片并没有严格控制变量而是为图方便均使用了P档 不过参数大体是接近的~（ps由于我在拍摄对比图片时忘记此前对K20D的饱和度、清晰度的调整归零，因此K20D所拍的照片都是饱和度+1;清晰度+1的 不过我在调整好设置的条件下昨天又出门拍了几张，所得结论不变）

以下所有相同构图的一组图片，上方的为K10D所拍摄，下方的为K20D所拍摄（自然色彩模式）。

总结

通过以上实拍对比可以发现，K10D的色彩与现实更加接近，各种颜色的还原恰到好处；而K20D的色彩则更加浓郁，和肉眼所见有一定的偏离，更具风格化。这和我印象中CCD成像更加复古类似胶片有很大的差异，K10D的色彩好就好在真实的呈现了肉眼所见，22-bit A/D转换器确实不负众望 ；而K20D虽然存在一定的偏色情况，但其浓郁的色彩、丰富的色彩模式是我对它爱不释手的主要原因。

莫幸发962宾得K10D跟尼康D80选择哪个好呢?最近想购机各位大大给点建议
华齐陈13658461010 ______ 宾得K10D确实是一款非常不错的相机,最近获得了2007年欧洲相机大奖(准专业数码相机类),但其配套的镜头在国内比较少,做为业余摄影爱好者,也是一个很不错的选择.

莫幸发962想买个入门级单反,看中了宾得的kx和k10d,网上看了一圈觉得似乎各有优点不好取舍,求指点!!! -
华齐陈13658461010 ______ 选择kx或k10(我用手机懒…不打D了)得看你的预算以及日后的镜头投资情况. 先说kx.可以说kx是宾得单反扭转劣势的试水之作.我之所以这么说的理由是,比起之前的宾得机型,kx改善了对焦速度,并且使用了控噪性能良好的传感器,使...

莫幸发962请教各位老师宾得K10D适合影楼用吗?请问还用那几款相机适合影楼群用?
华齐陈13658461010 ______ 佳能400D你就不要想了,,那机子就一台工业垃圾,买回来后悔死你..跟宾得K10D没得比的~宾得之所以不适合影楼并不是他的机子差,主要是镜头有局限,可选择的少,不过如果你不打算入手太多的头的话,还是可以买的,毕竟比400D好的太多了..宾得K10D是跟尼康D200一个档次的机子..相当于佳能的20D,佳能400D是入门机,很差的~而且手感不好~如果在K10D与400D之间选择,最好买宾得~如果因为资金问题,买不了那么多头,也建议你买宾得K10D+适马17-70或者原厂的16-45的头,一般也就够用了,想拍人像可以淘个手动的851.5的头,两个头一般的活也就够干了~反正,千万别买400D~

莫幸发962宾得k10d 有没有实时取景功能》 -
华齐陈13658461010 ______ 单反都是通过五棱镜来实现实时取景的,自己趴在观景窗看的... 你说的是否live view(LV),实时显示取景? 这种新机器一般才有... 不过这个功能要谨慎选择.虽然有些情况下LV方便了.但是LV的实现有的是靠打开快门,使用相机自身...

莫幸发962宾得k10d拍摄 人文 配什么镜头? -
华齐陈13658461010 ______ 拍人文,不同风格用的镜头也不同,看你的喜好.普通人文喜欢用50mm的视角,很多大师都喜欢这个焦段,在APS-C的K10D上,应该选择30-35mm的镜头,这样小公主Fa31、暗星FA35F2、福利头DA35F2.4和适马30F1.4都是不错的选择,...

莫幸发962宾得K10D是配18 - 55好还是配16 - 45的好?
华齐陈13658461010 ______ 当然16-45,不要买18-55,浪费钱.我就是K10D,先上的18-55,后来觉得不爽又上了16-45,完全是两个世界了. 感觉16-45和18-55比起来在解像力和色彩方面都比18-55强很多,2000块钱花得值,那个16-50/2.8估计应该更好,不过价格有点贵了.一个16-45,旅游,环境人像都可胜任.

莫幸发962宾得k10d适合拍人像吗 -
华齐陈13658461010 ______ 适不适合拍人像,更多的是和镜头有关系.不过总的来说宾得对肤色的处理是比较糟糕的.

莫幸发962各位老师k10d性能和成像怎么样?照相馆适用吗? -
华齐陈13658461010 ______ k10d属于目前的中端机身,性能和质量都不错.金属的防尘防水滴机身,11点对焦,12bit信号处理能力,千万像素,机身CCD防抖,最快1/6000秒快门...种种性能,基本上能够和尼康的当家中端机D200抗衡了,但是价格只有尼康的60%左右,...

莫幸发962宾得K10D与K5成像特点比较 -
华齐陈13658461010 ______ 当初入宾得,最主要的原因是喜欢宾的色彩.镜头和机身都决定出片色彩,其中机身感光元件占主要因素.从CCD到CMOS,最大的改善是高感,K7、K5、KX、KR高感到ISO1000躁点都控制很好.但CMOS在色彩上的表现远远不如CCD.即使用以前的老宾得头,分别搭配CCD和CMOS的机子,色彩表现差别仍然很大,绝对肉眼可见.当宾得失去了“宾色”,又没有尼康的锐度和佳能的对焦快,也没有广泛的镜头群.那宾得的卖点在哪里呢?我是不知道了,呵呵,死抱着自己的K10D不放.

莫幸发962宾得镜头AF标示的,用在K10D上可以吗 -
华齐陈13658461010 ______ 宾得没有“AF”这个标示,应该是“FA”吧.FA是宾得胶片时代的镜头,(现在的DA是数码专用)可以在现在的宾得DSLR上面用,包括K10D,毕竟卡口都是一样的.不过因为那时候技术落后...
