Those of you who preordered the new 24-105mm Sigma A-mount lens will certainly be unhappy to read this: SAR reader Keith got this note from Sigma US:
Good afternoon,
Unfortunately, production of the 24-105mm has been halted in all mounts. It was originally supposed to be released for Sony this month, but now production is on an indefinite hold. I will save your e-mail address and get back to you when we know more.
Please let me know if you have any questions.
Have a great day!

1st blood! and admin please dont on hold SR5 ILCE FF A9
Sigma Rumors posted a couple weeks ago Sigma was halting production for this lens in all mounts. No huge surprise the Sony mount is “on hold.” The only question is what took people with Sony mount pre-orders so long to get the memo.

Sigma is a good engineering company, they should sell their designs under license to a production company that knows how to build lenses and stop making excuses.
R.I.P A-mount …. //prepares black jacket
UM…..so because Sigma stopped production on all mounts, A-mount is dead?
So that means that ALL camera mounts from all makers are dead!? Oh know
F8^%&#*& moron.
Sigma can’t build E-Mount either, yet several other lens manufacturers seem to have no problem doing so. Sigma sucks.
Sounds like it’s on hold for all mounts – manufacturing issue?
I talked to the Sigma reps about this and they said they only have a single factory, and they’re improving their quality assurance processes, which has slowed production. The Canon and Nikon mounts have been temporarily slowed or halted, too, but will resume.
This Sigma 24-105 really is an awesome lens; it’s our walking around lens for both Canon and Nikon, and beats all the kit lenses for price, quality, and sharpness.
Good insight news!
Sounds like the production pieces are not meeting the specifications of the hand built prototypes. I would reserve judgement of optical quality and sharpness until the actual production samples are released and then test several randomly selected samples to accurately evaluate the lens characteristics. This “delay” sounds very suspicious and may portend more serious issues that have to be resolved.
Agree! You dont just STOP production unless theres a VERY serious manufacturing or QA problem.
This lens has been shipping for months, just not in Alpha mount.
The Sigma rep is blowing smoke up you a$$, they have serious problems. Looks like a good lens to avoid.
I talked to a guy on a San Francisco street using the Sigma 24-105mm f/4 in EF-mount (spotted a Sigma Global Vision lens I couldn’t identify; of course I was curious). In short, he swore by it, and said it replaced his EF 24-105mm f/4 IS USM (which I use). Fairly convincing (to me), but I do need the environmental resistance of the L lens.
If only Sigma included weather sealing in more of their lenses. And I don’t know how this bodes for the long-rumored 24mm Art (not that it matters to me anymore, as I went Samyang).
Typical Sigma BS, always lame excuses little action.
I really wanted this lens in A-mount… I was waiting for it for a long time before I gave up.
i did wonder if sigma are managing capacity, if theres big demand and profit on the primes and the 150-600, then that might be another reason to shelve less profitable lens production.
Got tired of waiting for this ONLY Sigma lens I was interested in, aside from 120-300/2.8.
Now I love my old Tamron 35-105/2.8 SP built well, smaller, and very excellent on a99/77 EVF. Great match with Tamron 20-40 and 70-210 original SP’s.
Sorry Siggy… too late.
How about 20-150mm? I’m sure it can be done. I’ll take it slow at F4.
The 24-105 A-mount is still on hold? Whats going on at Sigma? Any news? Someone?
