I bought a used Nikon D50 back in November from a friend of mine. It's been a long time since I've used a "real camera", actually it's been about 20 years! My first real camera was a Nikon FM20, a manual SLR. I took it with me to Europe for 6 months and captured some of the best photos. I only wish I had taken more :)
When I first starting using the D50 on "Automatic" the photos were coming out really bad. I took it off the auto and went to 100% Manual and many of the photos were coming out slightly fuzzy. Now I shoot in manual and let the camera finesse the final focus. The more I use the camera, the more I am figuring out.
So now you can look forward to better food photos. Though I may occasionally still use the iPhone :)
