Choosing a broom lens universe

Many people who do not want to be bothered with the ritual of dressing-change lens and carry additional lenses, and therefore, the broom lens universe. This lens has a focal range widely, from width to length (tele).
In the market, the lens of this model is expensive and there are cheap, there are good quality, there is a bad quality.

This is the lens broom universe that I recommend:

1. Nikon 18-200mm VR f/3.5-5.6 VR II Version

If you use Nikon cameras, the lens is arguably the best of image quality and body design. Performance auto focus can also be relied upon. Picture quality is very good and sharp in 18-70mm, then quality will fall primarily between 135-200mm. In addition, the price is relatively high and probably more expensive than your camera.
2. Canon 18-200mm f/3.5-5.6 IS
Image quality may not be as sharp as the Nikon 18-70mm, but overall, this lens is more consistent than the Nikon, especially for long-distance photo (tele). The price is also much cheaper. Unfortunately the auto focus is still using old technology, so there’s still votes and less rapid. For users of Canon cameras, this lens is the best choice.
3. Tamron 18-270mm f/3.5-6.3 VC Macro
This lens is the lens to reach the most distant comparison with the above lens. Image quality is good enough from 18-135mm after that somewhat decreased, especially at the ends, at a distance of 200-270mm. This lens worthy of choice if you want to have a lens that is very far-reaching, such as photographs of wildlife (wildlife). To lack (like Tamron lenses in general) lies in the performance of auto focus a bit noisy and often failed to lock the subject of the picture.
4. Tamron 18-250mm f/3.5-6.3 Macro
The cheapest price does not mean the most ugly, but on the contrary, the image quality is more consistent than the Tamron 18-270mm lens above and below the Sigma 18-250mm. The size is also smaller and lighter, perfect for a walk. The drawback is no built-in stabilizer, so users Canon / Nikon quite difficult when the images in a dark room.
5. Sigma 18-250mm f/3.5-6.3 OS HSM
The design of this lens and auto focus faster performance, almost silent and more accurate than Tamron lenses above. But even less consistent picture quality. For example at 18mm focal length sharp images, but at 50mm, not sharp.
