It’s not designed, I don’t think, to be pro glass. It’s designed to give those higher-end consumers a lens that looks great, shoots well, produces images vastly superior to competitors in the focal range and offers a uniquely wide-open aperture. For that, it easily stands out as a top contender for APS-C camera owners looking to get something far better than a kit lens at a focal range that usually screams “beginner.”

I have the novaflex nikon adapter I use with my GH2 -- very nice, stopless aperture control so you can use it with G lenses like the Tokina 11-16. I'm also excited about the idea of getting this zoom and a speedbooster or lens turbo, but they don't make them for Nikon lenses yet.
No, Nikon lenses have aperture lever.
fantastic! i'm sold!
Nope, the adapter has a tab that touches the tab on the back of the lens, that operates the iris inside the lens. All nikon mount glass has it, canon does not. That's why you see a bunch of us with nikon mount glass unless it has an aperture ring built into the lens, like old glass or new cine style lenses.
im struggling to understand how that works, having seperate aperture blades in the adaptor itself. Would you set the lens to 1.8 and then be able to adjust on the adaptor for stopping down? Without a Canon or Nikon body, how would I even be able to set the lens to 1.8?
I own neither a Canon or a Nikon. What options are available for being able to change the aperture on the fly when using on Micro 4/3rds?
I may now actually buy an EF mount lens! Internal zoom/focus = gushy feeling!!! :D
Too much info! :-p
@Vitaly_Kiselev Clearly I'm having a premature ejaculation. :p
Just needs BMPC to ship this year :-)
pocket blackmagic + tokina 11-16 2.8 + sigma 18-35 1.8 + speedbooster = orgasmic combo
Add here lens turbo and will be sweet pair.
Holy shnikeys!!!

$799!! That's a deal! The expected date is the same as the BMC4K! LOL. The devil is tempting me...
Any word on price?
The key to understanding the Sigma 18-35mm F1.8 is to realize that it gives the same control over depth-of-field as a 28-50mm F2.8 would on a full-frame camera - it also allows you to shoot at wider apertures in any given situation, effectively cancelling out the greater low-light ability that a larger sensor would otherwise give. And, especially if you own a high-end APS-C camera, that can help to reduce some of the motivation for moving to full-frame.
I can easily see this lens being the best friend to many working professionals and a lot of enthusiasts, too. It could, without hesitation, be the go-to lens for portrait and wedding photographers across the globe. The Sigma 18-35mm f/1.8 is a rock star, no doubt!
