Hi, I have 16-50mm and 55-210mm lens and I'm browsing some inexpensive lens that are good talking wide angle images. The SEL16F28 lens seems affordable but I doubt if this have difference in my current SELP1650 because it can also capture pictures at 16mm. I want to buy the 16mm f/2.8 because i plan to avail the wide angle and fish eye converter in the future. I just need to know if it is reasonable to buy even if I have the 16-50mm lens Thanks in advance! Can someone post comparison shots in same subject using SEL16F28 at 16mm and SELP1650 at 16mm too?
