What lens does Pentax k50 use to take portraits and landscapes?

What is the budget? The prices of different grades of lenses vary greatly.

If you want to take a picture of a landscape portrait, you can consider the original factory 16-50 F2.8 or the cheap Longteng 17-50F2.8.

If you just shoot the scenery, even the performance of the range hood is not bad. If you have money, you can pay attention to wide angles, such as DA 14, DA 15, and ultra-wide Sima 10-20.

There are many high-quality portrait fixed-focus lenses to choose from, such as indoor FA 3 1, DA 35, DA 55*, DA 70, FA 77, FA50 and so on. It seems that only DA50- 135 is more practical for portrait zooming.

The price of each lens is different. Generally speaking, you get what you pay. In fact, any lens can make a good film, as long as it is enough under its own economic conditions, it is not necessarily the best and most expensive.
