What's the problem here?
Think you need to do some homework, that Z 16-50 is a very good lens, it maybe not be the fastest thing in the world but IQ is really good. It also sells for over £300 stand alone
They could possibly include the 24-70f4. If anyone was willing to spend another £400 or more.
Even the 18-55mm kit lenses from Budget DSLR sell for £50 or so. It's an entry level camera, you can't expect a high end lens on it for this price.
oh i know but it makes the lens worth about £1
