Sigma 70-300mm f/4-5.6 DG Macro £100, $140

It might be Cheap, but you get what you pay for

At only about a quar­ter of the price of Nikon’s most up­mar­ket lens on test, this Sigma is a di­rect com­peti­tor in that it’s full-frame com­pat­i­ble and has the same zoom range. It also fea­tures a ‘macro’ fa­cil­ity that’s avail­able in the 200-300mm part of the zoom range, some­thing which is lack­ing in the Nikon lens. Se­lected via a switch on the lens bar­rel, this en­ables close-up man­ual and aut­o­fo­cus­ing while also lim­it­ing the zoom range, and in­creas­ing the mag­ni­fi­ca­tion factor to as much as 0.5x. The same fa­cil­ity is avail­able in the Sigma APO and Tam­ron AF lenses on test.

In other re­spects, how­ever, it lags a long way be­hind the pricier Nikon lens. The au­tofo­cus sys­tem is driven by a ba­sic and fairly noisy elec­tric mo­tor and there’s no op­ti­cal sta­bil­i­sa­tion.

Per­for­mance

Lev­els of sharp­ness and con­trast are okay over­all, but dis­ap­point when com­bin­ing the long­est zoom length with the widest aper­ture, which you might need to do in or­der to keep shutter speeds fast, es­pe­cially in the ab­sence of sta­bil­i­sa­tion.
