Converters<br />
Teleconverters and autofocusing<br />
Customers are sometimes perplexed to find that their converter won’t autofocus with a<br />
particular lens. The reason is an optical one: they lose light - 1 stop for the 1.4x, and 2<br />
stops for the 2x. Camera manufacturers design their autofocus sensors to work with<br />
lenses of f8 or faster, and so when a 2x converter is attached to a 70-300mm zoom with<br />
an aperture range of f4-5.6, this becomes f8-f11, and at the 300mm end, autofocusing<br />
stops. It’s only really a problem however, if you’re photographing moving subjects.<br />
Kenko 7-element<br />
2x autofocus converters<br />
Double the power of your lens. Fitting<br />
between the lens and the body, they retain<br />
all metering functions, and are ideally<br />
suited to focal lengths above 50mm. The<br />
7-element design and multicoating keep<br />
performance loss to a minimum. Please<br />
note the restrictions regarding autofocusing<br />
in the panel above. £88.95<br />

New Di lenses<br />
The 28–75/f2.8 is a compact zoom with fixed<br />
aperture, and the 180/f3.5 Macro a high performance<br />
telephoto with 1:1 subject repro. This<br />
year they are joined by a 17–35/f2.8-4 and soon<br />
a 70–200/f2.8. All these lenses have a ‘Di’<br />
suffix. They still cover a 35mm negative, but the<br />
light exit path has been optimised to minimise<br />
colour aberrations on digital cameras.<br />
