Sigma is on a roll in the digital slr world. Seems like after 20 plus years of languishing as a third tier lens manufacturer, the value base glass maker has come across a series of designs that has even Photography magazine buzzing almost every issue. So when they recently came out with a 200-500mm f2.8 lens, the reaction should have been a predictable one. Until the size became apparent. It’s HUGE.
Weighing in at nearly fifty pounds, this Sigma lens is not for anyone with a steady hand and a regular gym membership. In addition to covering the popular 200-500mm range at f2.8, it can double the focal length and still clock in at f5.6 – which isn’t too bad if one has a beefy tripod to hold it still. This Big Bertha like lens would be very popular for astrophotography, sports and wildlife shots thanks to its low dispersion glass elements for image correction. The multi-layer coating reduces glare and ghosting, and it’s specially designed lens hood blocks out annoying ambient light. There is also a built in LCD panel for live view when not looking into the camera’s SLR viewfinder or LCD. The lens is powered by a single dedicated lithium ion battery (BP_21) for auto focusing and zooming operations which would make holding this mammoth a heck of a lot easier.
But the cost is equally heavy at a hefty $28,000.
