Super price for a top lens !!!

Vorneweg .... am a layman and have considered long what lens should I give my wife for Christmas or want for your Nikon D3100. To select the Tamron 70-300mm stood (Link below!) Or this orig. Nikon lens. While the Tamron has a larger zoom range and a switchable Macro function, it no anti-shake, and is much more difficult! Hmmmm ... after hours of reading reviews Testberichte- and I have both decided to place it under the tree and test my wife and himself decide to leave.

The Nikon lens is only about 30 more expensive, but has been awarded the contract because:
- You can deactivate the macro function when Tamron only somewhat awkward again
- Color reproduction and picture sharpness while Nikon in our opinion better fails
- The Tamron no anti-shake performance has been integrated, which is very helpful in pulling the zoom out of hand without a tripod
- The Tamron significantly heavier fails
- The mechanism at Nikon better "hits" and more evenly running as the competitor
- The zoom range of the Nikon better to the already existing kit lens 18-55mm supplemented (no "hole" btw 55 and 70 mm.!)
