I wasn't going to write about another lens roadmap. Honestly, my eyes glaze over when brands drop another "we're going to release twelve primes over four years" press release. But Sigma's June 2026 update actually has something I've been begging for, and I think a lot of photographers missed it because of the bigger headlines.
So here we go.
What Actually Got Announced
Sigma dropped a refreshed Contemporary and Art lens roadmap this week focused on Sony E and Canon RF mounts. Buried past all the sexy 35mm f/1.2 and 24-70mm f/2.8 II chatter, there's one specific item that caught my eye: faster internal zooming on the new 28-105mm f/2.8 DG DN Art.
Yeah, you read that right. f/2.8 across the entire zoom range, in a 28-105. Not a constant f/4 with weight savings. A proper f/2.8 zoom with a usable wide-to-portrait range. This is the lens I've been wanting for three years.
The closest competitors — Sony's 24-70 f/2.8 GM II, Canon's 28-70 f/2L, Sigma's own 24-70 f/2.8 DN Art — all top out at 70mm or 72mm. Useful, sure, but you still need to swap to a 70-200 for portraits or tighter environmental work. Sigma's new 28-105 collapses that into one lens. Less weight in the bag, one less thing to swap mid-shoot, one less seal point for dust and rain.
Why I Care
Shoot a wedding or event with me and you'll see two lenses on me: a 24-70 f/2.8 and a 70-200 f/2.8. That's it. The weight is stupid. The 24-70 stays on for 70 percent of the day, then I swap to the 70-200 for ceremony and family formals. If a single lens can cover 28 to 105 at f/2.8, I'd lose maybe 200 grams and one full battery's worth of swap time per event.
For documentary and travel shooters, this is even bigger. One lens that does wide environmental AND portrait compression without compromise. My OM 12-40 f/2.8 PRO II is the MFT version of this idea, and it's on my GH7 maybe 90 percent of the time. The full-frame equivalent has been missing.
The Catch
It's not out yet. Sigma says Q1 2027, which means pre-orders probably open late 2026. Pricing wasn't confirmed but expect to be in the $1,400 to $1,600 range based on the 24-70 Art pricing. That's not cheap, but it's also not the $2,200 Sony GM II tax.
Weight is listed at "under 900 grams" — close to a typical 24-70 f/2.8. Not a miracle, but not a brick either. Filter thread 82mm, which means my existing 82mm polarizer and ND filters carry over. Small detail. Big deal in practice.
The Bigger Picture
Sigma has been quietly eating the third-party lens market for full-frame mirrorless, and honestly, I'm here for it. Tamron has been chasing the same playbook with their G2 lenses, but Sigma's optical quality has been a notch above for the last two generations. The 35mm f/1.2 DN Art is still my go-to recommendation for anyone asking "what prime should I buy" — the rendering is just magic.
The 28-105 f/2.8 fits a pattern: Sigma is no longer trying to copy Sony or Canon. They're picking the specs photographers actually want and shipping them. The original 35mm f/1.4 Art was a giant, the 35mm f/1.2 is reasonable-sized. The 24-70 f/2.8 II is lighter than the GM II. Sigma has decided that size and weight matter, and the roadmap shows it.
I'll believe the 28-105 f/2.8 when I have one in hand for a real shoot. But on paper, this is the most excited I've been about a zoom lens announcement in a long time. Probably since the original 24-70 f/2.8 Art, which I bought and immediately stopped swapping lenses as often.
More to come when I get a review unit. Until then, the gear-buying urge is on hold and my wallet is grateful.
