Does anyone have a Nikon Nikkor lens – 50 mm – f / 1.8?
I'm looking to buy and wondered what their users think about it? I have a Nikon D90 body. Thanks!
If you want a normal lens, try the 35mm f / 1.8 in place. I have one on my D90. The 50 mm will be a little narrow, but will be fine if you are doing portraits.
