I feel very honored to be able to get in touch with this lens earlier, and because of this, I have time to use this lens to take photos of many different subjects. Personally, the impression of this lens is... very heavy, I never thought that PENTAX will produce a The 50 focus is still heavier than the FA31 LE. This lens is very solid workmanship. In order to achieve all-weather waterproof (AW), there are not many gaps seen from the outside. The pictures taken with the DFA50 are as solid as the workmanship. Whether they are connected to the K-1 or K-1 II photos are satisfying or even touched, because the DFA50 describes the details very well and the bokeh is quite beautiful. , with 77LE completely different grades, shooting a lot of subjects down makes me feel a good mirror, some foreigners say that can be comparable to Zeiss, sharpness beyond SIGMA 50 ART does have this possibility, use it to take out photos seems to be more than other The PENTAX lens is more intense. In order to let everyone feel the original quality and color, the photos are still using the camera's native JPEG thumbnails to put on the network. Unfortunately, many website software still cannot capture the EXIF ​​of this lens. PENTAX DFA ★ The 50mm F1.4 lens was originally scheduled for sale in the spring of 2018. It will be postponed according to the original news, but I believe that this lens is worth waiting for and we look forward to the day it was officially released.
