Find an interesting subject - and the lens and the camera and the grain and the noise just don't matter, is the photo fun to look at? The only thing that can get annoying is bad focus and camera shake.All subjects are interesting - when looked at in your unique way. Find what you like and bring that into all the photos. It will take all your life and will change as you change, which is why art is such a good hobby.You can always crop more - people have fleeting expressions, you need to shoot NOW. Don't worry about exact framing, just make sure you get all you want in the frame, crop out the bad parts later.Someone somewhere has taken a better photograph of that - just look through flickr. Concentrate on having fun. And make sure you experiment and come up with your own way of looking at things.
