There are an enormous number of factors to consider when buying a camera. The first thing to consider is the use of the camera; for those interested in taking selfies on nights out in clubs perhaps sticking to a camera phone is the best bet. For those who are more serious in their photography then the subject of the shot is important. Are you going for close ups or landscapes? Underwater? Professional compositions? Whatever your use, and whatever your aim, the lense you pick is going to be essential to maximising your goals.
The problem occurs when the lense becomes damaged and replacements need to be decided upon, and then bought. Lenses can be notoriously expensive and oftentimes it’s just as cheap to replace the whole camera. Thankfully there are professionals who are more than willing to help with any lense related issues you might have, and some might even charge a reasonable rate as well.
