If you’re planning to pick up the new Sony Xperia Z1 here in the U.K. as soon as it becomes available, you may want to shop around first to see where you can get the best deal for you.

A number of retailers and carriers are throwing in some pretty nice freebies when you pre-order, including the new QX10 camera lens attachment worth £180, and the Sony SmartWatch 2 worth £170.

Carphone Warehouse and O2 appear to be offering the best pre-order deals so far, which give you a free Sony QX10 camera lens attachment worth £180, plus up to £65 worth of content from the Sony Entertainment Network.

The QX10 was announced at IFA alongside the Xperia Z1 earlier this week, and it features an 18-megapixel Exmor RS camera with CMOS sensor and optical image stabilization, and 10x optical zoom. The device clips onto the back of your smartphone and connects to it wirelessly, allowing you to snap pictures and control things like zoom and focus from your smartphone itself.

In addition to the QX10, Carphone Warehouse and O2 will give you £65 worth of free content from Sony Entertainment Network — including five top movies, an exclusive movie access pass, and 60 days of free music streaming.

If you don’t fancy the QX10, then Phones 4U and EE are offering a free Sony SmartWatch 2 worth £170. If you choose a 4G plan, Phones 4U will also give you a free wireless speaker worth £120. Alternatively, the retailer will give you 50% off a Sony Xperia Tablet Z.

These offers are only available with pre-orders, so if your’e interested, be sure to place your order before the handset actually goes on sale. They’re also only valid while stocks last, which is another reason not to wait to long.
