I take most of my picture with a simple Nikon SLR camera but sometimes I use my Iphone (smaller and more convenient while running etc)
I just bought a new lens that I’m very much in love with. It’s an Nikkor 50mm/1,8. That lens is perfect to take portraits with as it creates a nice focus on the person and blurs everything else. I will not bore everyone with tech talk ( or show my ignorance) but that lens is amazing. Love at first sight.
I also use the old 18-55 mm lens that came with the camera, boring but useful.
My next buy will probably be a better flash and a lens somewhere around 50-300mm.
Update: I just got a Tamron 70-300mm/4-5,6
I use Lightroom 3 for Mac to edit, store and convert my RAW pics to jpeg.
