Well, it may or may not be true; I don't know enough about cameras to say. The sentence is also correct, despite the apparent lack of a verb. It is implied in this case, and the verb is "is".

You meant to ask, "Is this sentence grammatically correct?" Yes, it is. This is a common speech pattern that expresses a proportional (or inversely proportional) relationship between two conditions. I call this pattern "the more, ... the more". The sooner he returns home, the better I'll feel. The more, the merrier. The faster you go, the more fun it is. The slower this sled goes, the safer I'll feel. The less he speaks, the less I have to listen to his nonsense. The less he speaks, the more I like it.

the more the better 省略句吧可以这么用的
