Sigma 70-210mm Zoom IA (Intelligent Auto)
Launched September 1992
Sigma 75-300mm F4-5.6 DL Zoom lens
Sigma Launch their new De-Luxe lens.
There has been a move by some camera manufacturers to introduce a lower-priced range of lenses. Unfortunately, these ‘budget’ lenses have had to sacrifice many features in order to achieve their lower selling price. Many lenses no longer have zooming and focusing information engraved on the lens barrel, depth of field information is sadly missing on many, and indeed some have taken the drastic step of utilising a plastic back mount.
As Sigma are the largest lens manufacturers in the world, they have been able to develop their 75-300mm deluxe lens to sell for £149.95 in auto-focus fitting! This new departure in the cost of auto focus photography has in no way compromised the quality of the lens.
In spite of its compact size (it is the shortest of all the 75-300mm AF zoom lenses currently available) the Sigma 75-300mm DL lens uses two low-dispersion glass elements in the front lens group to produce superior optical quality. Its lens barrel is engraved with a focusing scale and depth of field information in both feet and meters.
A generous manual focusing ring and metal back mount complete the overall quality the lens delivers.
