Or at least that’s the idea with vacation lenses, but the trade-off for their obvious ease-of-use and zoom range is usually a distinct lack of optical quality. And while Sony DT 18-200mm F3.5-6.3 theoretically possible to make a high-quality vacation lens.

Sigma 17-70mm F2.8-4 DC Macro borders start with good figures here whereas the corners are somewhat soft and you should stop down to f/4 to overcome these corner problems. The peak performance is reached at f/5.6 with a generally very good quality across the frame. A major new feature is, of course, the OS (“Optical Stabilizer”). As already mentioned, Sigma 17-70mm F2.8-4 DC Macro is impressively efficient and as good as the corresponding genuine manufacturer implementations. The Sigma 17-70mm F2.8-4 DC Macro center performance is very fine straight at 17mm @ f/2.8 and it even gets excellent when stopping down. Click here to get the most of Sigma 17-70mm F2.8-4 DC Macro.
The Sony DT 18-200mm F3.5-6.3 is nicely sharp when used in the mid-range of its specifications: not wide-angle or telephoto, and with the aperture stopped down about halfway. Sony DT 18-200mm F3.5-6.3 optimum performance with respect to sharpness can be achieved with the aperture set to ƒ/8 and a focal length between 35mm and 70mm.

Here is a summary of Sony DT 18-200mm F3.5-6.3 review from a satisfied customer:
a travel photographer’s dream
As a professional landscape photographer who feels compelled to carry a wide variety of lenses, I found this lens has helped me lighten my carry on case. This is a versitile lens that provides fine steady quality under most landscape conditions. It replaces 3 lenses that I used to carry on my travels. The reproduction quality that I get from most enlargements from my new alpha 700 with this lens is top quality. As others note, I wish it had sturdier materials but if it gets banged up, it is reasonably inexpensive to replace. If you add a set of macro filters, it does a great macro job on flora. You will find that on most shoots, you will likely use this lens over 75% of the time. That helps keep the dust and dirt from getting on the sensor when you change more frequently as I used to do.
In summary, you can achieve nicely sharp images with this Sony DT 18-200mm F3.5-6.3 if you shoot in within a limited number of apertures and focal lengths: generally, ƒ/8 or ƒ/11, and between 35mm and 70mm.
