Latest Lens Addition	Tamron AF LD Aspherical IF Macro (# 185D) 28-300mm F3.5-6.3
Latest Review Posted	Sigma 1.4x DG EX APO Teleconverter This adapter has shown to be very sharp coupled with the 70-200 f2.8, makes a great 300mm f4 for birds and sports. It also works well with the Sigma 70mm macro and probably all Sigma DG lens of longer focal length. the shallow design has a disadvantage: it wouldn't work with shorter focal lens, as the rear glass element of the lens will interfere with the coupler (But then again.. i don't know if this is symptomatic of all TC or just specific to this TC) would have give it a 9 if not for the in-compatibility.
