I guess this is a bit random. Looking around a bit, there very few reviews for the Sigma 50-150mm 2.8, and most of the "major" sites seem to conspicuously ignore it. The reason this seems weird to me is because it is supposed to cover an important niche, being the 70-200mm 2.8 equivalent for DX - APS sensors (and at around 1/3 of the price). This alone makes it sound important. Other third party lenses that cover similarly important niches got much more coverage (notably the Sigma 10-20mm). Why do you think it was ignored? What reviews you can find agree that it isn't a bad lens at all. Do you think that it is not notable enough, and i am just being weird?
