It's good to have options. Let's see where the price & performance end up compared to the much lighter but less wide Tamron 28-75 and the Sony GM.

I shoot at 24 often. For me the tamron is not wide enough.

For me...well in Sweden the Tamron 28-75 costs more than it did when it launched a year and a half ago. It's going to be .. interesting to see what this lens will cost in the U.S vs in Sweden with its..tanking SEK. I have become a fan of "cheap vintage lenses" lately. Anyway, besides all that, I suppose it's good with a third member in the standard FE zoom range.

Why does it zoom opposite direction than native Sony E and even the native Panasonic L Mount Alliance lenses...?

What advantage does Sigma believe that inconsistency would provide the E or L user? I'll assume they'll be prepping this for a Canon Mirrorless mount, and expecting higher sales from that version... Or did Panny agree to L Alliance only upon the stipulation that Sig make a compromise, so not to jeopardize the native version...?

This is exactly what happened with the A-Mount 24-105/4 Sigma Art. It zoomed opposite direction. I loved that lens but never could get used to the zoom being inconsistent with all my others.

This is no new problem with Sigma lenses. They've never been consistent with zoom direction. My EF Sigma 12-24 EX zooms in the non-Canon direction. My A-mount Sigma 70-200 EX zooms in the Canon direction.

Sigma does seem to keep closer to Canon. Their SA mount uses EF protocol. It looks like not even their SA mount Global Vision zooms have a consistent zoom direction.

Sony reversed aperture ring direction on E-mount from the Minolta direction used by their 135mm STF.

The 135 STF "aperture" ring turns in the direction of the Minolta manual focus SR-mount (MC/MD) lenses, if the Sony turns in the opposite direction, it turns like Nikon. Zeiss Contax (and Yashica) lenses turn like Minolta, so, I assume Sony tried to appeal to Nikon lens users.

Did I tell you guys that the dedicated aperture control on the lens is old fashioned?

Yes, the aperture controls on Sony's E-mount lenses operate in the opposite direction of those on the Sony A 135mm STF. The Sony FE 100 STF aperture control is backwards to the Sony A 135STF.

Sony may have had aperture controls on non-Alpha lenses before they acquired the brand. The rebranded 135 STF may be the outlier.

I wonder if it rattles when the power is off, like their small primes?
Miranda F & Sensorex, Sony A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras . . .

It has a stepper motor not a linear electromagnetic motor.
