When I first learned that the Sigma 300-600mm f/4 DG OS Sports would cost less than $6,000, I thought it was a myth. Fast super-telephoto lenses have always been expensive. After all, high magnification and good image quality requires lots of expensive glass. And while the best mirrorless cameras have undoubtedly ushered in a golden age for long lenses, thanks to increasing image quality and good prices, fast glass at extreme focal lengths still comes at a premium far beyond the average photographer. Well, maybe until now...
I know, I know, you can buy a used car for $5,999 / £5,899, but comparatively speaking, the Sigma 300-600mm f/4 DG OS Sports does sit within the enthusiast ballpark. I’ve said many times before, we’re conditioned to spend big on cameras, but the most intelligent investment – in most cases – is quality glass. But don’t take my word for it, let’s put the lens I've taken to calling the ‘Sigmungandr’ (for all my Norse Mythology fans out there!) into perspective by taking a look at what else is on the market.
