Okay I'm debating if I should get the nikon 35mm f/1.8 and sell my nikon 50mm f/1.8. I have a Nikon D3000 so I can't auto focus with the 50mm and I can auto focus with 35mm. The 35mm is currently on sale for $170 including tax. Should I do it? What will be the downside to getting the 35mm?? Advice please
