Seriously, though, I'd still encourage you to enter, even if for the creative process alone. You may be able to turn the apparent shortfalls of your camera into an artistic reference to the subject, or somehow use it as a merit.
You don't have to enter the picture if you do not like it, but I'd ask what you had to lose?
