(\u539f\u6587: The two FIT dioptres I tested are achromatic and dual element. These features typically improve edge sharpness and reduce chromatic aberrations. In both respects the FIT dioptres performed very well. They produced impressive sharpness wherever I focused in the frame and details towards the corners were also pleasingly free from the colour fringing that some dioptres suffer badly from.)<\/p>\n

(\u539f\u6587: In summary the FIT dioptres are well-made and easy to fit to ports or holders with 67mm threads. Their price (in the order of $150-200 USD) is comparable to most other options, (e.g. SubSea, Inon) and is considerably cheaper than the Macromate ($600 USD). Image quality is impressive, with excellent sharpness both in the centre of the frame and towards the edges. Chromatic aberration is also well controlled. They can be used singly, or stacked together. If used outside the housing, they should be considered medium strength dioptres, but if we choose to mount them inside the housing the same dioptre will give more magnification. Having two power options from the same dioptre (inside or outside the housing) is a useful feature for the travelling photographer.)<\/p>\n
