The short answer is yes, they are trustworthy but your question seems to be more orientated towards the 'should you go for the cheaper version' kind of area. In some cases, people would consider the Tamron/Sigma equivalent to be better, but that's subjective and can take into account many things such as build quality, features, price and of course picture ...

With a tested Minimum Focus Distance (MFD) of 16.81 inches at 270mm and a Maximum Magnification (MM) of 0.26x, or approximately 1:4, you can't really do Macro photography with that lens. And since it is already slow at f/6.3 at 270mm, the minimal gain you would get in terms of MM by adding extension tubes would make the lens too dark to be very useful.

VR The Nikkon 18-200 has VR, the Tamron 18-200 does not. VR can give you an advantage worth two or three stops on the aperture. Nikon claim up to four stops There are some relatively cheap Nikon lenses that include VR. For example 18-55mm f/3.5-5.6G AF-S VR DX NIKKOR $197 55-200mm f/4-5.6G AF-S DX Nikkor VR - $247 18-200mm f/3.5-5.6G AF-S DX Nikkor ED ...

Your example above presumes that there are only 5 possible variables between to two lenses which could contribute towards the price. The fact is that there are many other reasons why the price could be higher: Build Quality Lens Coatings Perceived image quality Maximum aperture Aperture blade type I won't go on, because there are just too many. I would ...

There probably won't be a macro facility to 'activate' - the 'Macro' designation just means the lens can focus very close to your subject. If you are using the lens at the closest range available on the focusing scale (probably using the longer end of the zoom range at the same time) then you can safely claim to be practising macro photography. There is no ...

Nothing first person, but Photozone.de's tests and reviews are well regarded. Here's the relevant links: http://www.photozone.de/nikon--nikkor-aps-c-lens-tests/642-tamron175028vcdx http://www.photozone.de/nikon--nikkor-aps-c-lens-tests/838-sigma175028os To summarize: Build quality of both is good but not fantastic Neither is a great lens to manual focus ...

There's a focus limiting switch - so that when you're doing macro work, it won't hunt through the whole range. Look over the lens and find the switch and turn it off.
