引一下总评：
中等光圈下，锐度和对比度很好；
大光圈边缘较软，f4时紫边比较重；
变形控制好，对焦快
做工好，价格高，物有所值

Verdict

The SMC-DA 15mm f/4 AL ED Limited is a another desirable pancake lens by Pentax. The lens is capable of producing very sharp and contrasty images at medium aperture settings. At large apertures the border quality is somewhat softer so it may not be the first choice for available light photography (handheld) ... assuming that you can find a better one. The vignetting is hefty at f/4 so it's advisable to stop down here anyway to get rid of the problem as well. The amount of barrel distortion and lateral CAs is pretty decent for a 15mm lens. The AF speed is very high although that's usually not a really serious criteria for a wide to ultra-wide lens. The build quality of this tiny pancake lens is great and it's nice to see that a manufacturer still cares for high quality metal designs in this sea of cheap plastic lenses out there. Regarding its high price tag of around 650

没啥好挑剔了，除了价格

猫死除了光圈小其他指标都比DA14略高阿

为啥老用10d....
