and film grain. For testing I do, where I'm often looking for barely detectable differences in detail or grain, this sort of power is very useful.
 The Zoom Loupe is a seriously complex bunch of optics, hinted at

by its hefty 410g weight. There are eight coated elements arranged in six groups - enough to rival many fine camera lenses - and they produce a clarity similar to what I have come to expect from the Schneider loupes.
     There are two control rings, the upper one for focus and the lower for magnification ratio. At the base are two screw-on hoods, a translucent plastic one for use with reflective copy and a metal one for viewing transparencies. These screw on concentrically, the metal one on the outside, which is a neat way of ensuring that both hoods are kept with the unit.
     The Zoom Loupe is a very neat piece of kit which I don't hesitate to recommend. At £199.95 including VAT its price is comparable to other high quality loupes, while the zoom facility adds great versatility.

Isn't it strange? We spend
hundreds, maybe thousands, on
a camera lens to achieve the ultimate sharpness. Then, when
it comes to assessing the results, we're quite likely to use a £10
loupe with a plastic lens. The loupe is probably the most overlooked accessory in the photographer's armoury.
      A loupe is a lens. You wouldn't expect much from a camera lens with just one or two elements, nor should you expect much from a similarly constructed loupe.
Achieving decent resolving power requires several elements or groups of elements, just as it does in a camera lens. And this costs money.
 My favourite loupes have long
been those from Schneider, which come in powers from 3x to 10x. They are rather pricey, ranging from £112 to £200 plus VAT, but when you use them you can see why.
     Their price does start to
become a serious issue if you need more than one to cover different formats. A 3x or 4x magnification
is okay for 4x5 or medium format, but 6x or more is better for 35mm. With this in mind, the Zoom Loupe from the Japanese maker Ohnar looks a very attractive alternative. This has a magnification range
from 4x to 12x, making it suitable for all formats. The 12x setting allows scrutiny of the finest detail
