Sigma’s new 50-120mm F2.8 prompts a look back at an oft-overlooked lens that should have been a classic
Sometimes the future creeps up on you quicker than you expected. We’ve been thinking about re-starting our Throwback Thursday series for a while, but Sigma’s announcement of a 75-180mm equivalent lens for APS-C rather forced our hand.
This year marks 20 years since Sigma launched the original APO 50-150mm F2.8 EX HSM DC, a fast 75-225mm equivalent zoom for APS-C. A lens that gave APS-C DSLR users the range and utility of a classic 70-200mm but without the cost or weight of one.
DPReview marked the date with a single-paragraph news story along with Sigma’s press release, which was our standard level of lens coverage, back when the site had only a single full-time member of staff. We described it as “very interesting sounding.” Even for Phil’s level of British understatement, this is to significantly under-sell the lens. At a time when full-frame was out of reach for all but the most committed enthusiasts, this gave APS-C users a lens they hadn’t had before: a dedicated, fast 70-200mm equiv.
A slightly revised Mark II with very similar specs was released in 2008 and a copy made its way to the DPReview offices. It must have been a Nikon version as there are samples in the review gallery of the Nikon D5000 and D300S reviews the next year. There’s one shot by Phil, but the rest seem to be by me. Because I loved that lens.
I’d arrived at DPReview as the owner of both an APS-C DSLR and a 70-200mm F2.8 that I barely ever used because it was just too big and heavy to casually carry around. Even having bought it second-hand, it ended up being one of my least cost-effective photographic purchases ever.
The 50-150mm was a revelation: it was less than two-thirds the size of most 70-200mm F2.8s, less than two-thirds of the weight and something like two-thirds the price. Unsurprisingly, it was much more directly comparable with the dimensions of Canon’s popular 70-200mm F4, but offering a range I found more useful and with an extra stop of light capture on the APS-C cameras we tended to be testing.

It had the range to let me shoot things like bike racing and also made a pretty handy portrait lens, as it was much easier to handle and much less intimidating than a full-sized, tripod-footed 70-200 F2.8. And its compact size meant I did actually carry it around with me. And got more photos, as a result. The 50-150mm taught me an important lesson about how different formats can shine, if they’re properly supported.
I used it regularly over the time we had it and was disappointed when its stabilized replacement used the same housing as the 70-200mm F2.8 launched alongside it: giving up the size and weight benefits that appealed so much in the first place. It’s what perhaps made me a little over-excited when, years later, Fujifilm and Samsung produced similar lenses, even though they weren’t as small or light as I’d hoped.
I think I’ve requested or asked after a 50-150mm successor almost every time I’ve met Sigma’s CEO, Kazuto Yamaki. I thought I was reading too much into his response when he seemed more positive about the idea, last time we met.
But the only thing that excited me more than hearing that Sigma was about to lauch a spiritual successor to the 50-150mm F2.8, was unboxing it for the first time and finding out that the new lens is even smaller and even lighter than its DSLR forbear. And, looking at the images: sharper and better able to focus, too. I wonder if this new lens will inspire the same decades-long appreciation.
