I use the sigma on my FS700 all the time. Just be careful that you will get a black corner once you go all the way to 18mm-20mm. I also use the metabone speedbooster which I can go all the way down to 1.3f. So it low light it look amazing.

But overall this is a great lens. You see some sample here. With this footage I didn't grade it it cause I wanted people to see quality straight out of this camera. Just add a bit of denoise software on the footage that is all. On a side note I wish this lens was a bit lighter and I think for it price point it is a steal.

With this video I darken the footage just a bit. There is a bit of noise there but I was going for that grainy looks.

Very much looking forward to those samples :) especially high contrast ones like lights at night
Are you using a lens support?

got the SB just for this lens, expensive combination, but cheaper than several separate primes

we're talking about the 18-35 sigma 1.8 right? thats the lens i'm using. should i have talked about this in the speed booster thread instead?

just picked up this lens with the nikon speed booster for my gh3 and wow! stunning results, sharp as a tack with smooth bokeh. unbelievable to have what is essentially a 12-25 at 1.2, wasn't sure how much better it was going to be than my lumix 12-35 2.8 but it completely worth it. couple minor issues, i get a very slight vignette at the widest focal length, but fortunately only in stills mode, no vignette in video. also fortunate, i'm not getting any chromatic aberrations in high contrast areas and i was a little worried about that. highly recommend this combo.

Hmm

adapter with aperture control is a simpler affair with Nikon G => M43.

Here are your adapter options for for Canon EF mount => M43

1. No aperture control.
2. adapter with it's own blades (additional vignetting, etc)
3. redrock electronic solution (very expensive).

Nikon G adapter has a simple mechanical control of the lens' built-in iris.

rental houses are also starting to advertise it as "in stock", so it is definitely starting to appear.

Sigma must have messed up with the supply chain of the Nikon mount version. Ive had one on order for months, with no indication of delivery date.

there's 2 in stock at this moment on amazon

@dtr camera felt good in my hands today with an 11-16. but a long zoom would need rods and support in my opinion. 11-16 feels like a good stealth lens. add a speedbooster and you can really go wide

@smsjr : Yes I've seen those. They all require rods which i'm trying to avoid to remain compact and cheap.
