[NX10, 20mm F2.8] How is the convenience of i-Function lenses?
Recently, mirrorless cameras are popular in the digital camera market, because they been able to reduce the size of the camera while still keeping the performance of a DSLR.
These mirrorless cameras are the best with a small pancake lens. That’s why I’m going to take a closer look at the Samsung 20mm F2.8 i-Function Pancake lens released with the NX100. (It can also be used on the NX5 and NX10 with firmware updates.)
