    In the past a number of manufacturers made 28-50mm zooms for 135 format film SLRs. This lens duplicates that versatility for APS-C bodies, but the aperture is much larger on this lens. The bokeh may be roughly the same for crop bodies as the best of those vintage lenses (or maybe even a bit better) on a film body.

    Given that it's for aps-c sensors, makes me think the price will be reasonable as well. Like maybe in the 900-1100 range? Maybe quite a bit more though. Either way, this sounds like an awesome lens and definitely going to be looking for some reviews to see if it should be on my wishlist. At this point it already is.

    The first thing I'm going to do when I get my hands on this lens is mount it on my D700 and see what I can get out of it as far as cropping VS vignetting is concerned. I'd really mainly use it for star trail time lapses, so cropping down all the way to DX is okay if necessary but I'm hoping I can get the equivalent of 24-50 out of it one way or another...

    Nice to Sigma creating new and interesting glass. Although I find the range a bit limited (kind of like the Tokina 11-16mm 2.8) isn't it?
    I wished Sigma updated their beautiful 300 2.8 prime one day, so it would also perform with TC's.

    Are you wishing it would perform better with TC's because it does perform with TC's.

    For the 18-35 1.8 I am very interested in this lens. With the performance manufactures are getting out of cropped sensors, I am finding I get less and less interested in new full frame bodies and more with upcoming cropped bodies.

    Sigmas 300mm prime falls apart with 2x TCs. Also the Sigma 120-300mm f/2.8 outperforms it's sister prime.

    I would prefer a 24-70 2.8 on fullframe over a crop camera with a 18-35 f/1.8. Why?
    Because I am shooting FF mostly for thin DOF, and f/1.8 on a crop body gives the same
    DOF as a f/2.5 lens on fullframe. And while the f/1.8 lens allows for faster shutter speeds,
    a FF camera allows for higher ISO, which nullifies the advantages of an f/1.8 zoom on a
    crop camera for me.

    ... Which is an even thinner DOF for the Sigma 18-35mm F1.8 DC HSM, is it not?

    (Actually, for a Canon crop 1.6x body I think that the f1.8 translates closer to f2.8 DOF on a FF body with equivalent AOV/FOV. I can check further on that tomorrow, if you wish.)

    ... Or it means the same shutter speed at a lower ISO, allowing a more similar noise signature.

    I think they (Sigma) mean 28cm / 11", not 8 cm.

    Hi Ziggy, all of what you said is correct and thus the lens makes great sense for crop shooters.
    What I meant to say is, that on FF one gets the same effect with an f/2.8 lens and higher ISO.
    Therefore it brings nothing new to the table (for me). The Sigma is a DC lens, meaning it can't
    be used on FF without heavy vignetting, unfortunately.

    Definitely! A handful of us here at DGrin have had a chance to test the lens, and I believe that a few people now own it too. I've done a full review here, if you're interested:

    http://www.slrlounge.com/sigma-18-35mm-f1-8-ex-dc-field-review

    Bottom line, the lens is flawlessly sharp, and built like a Zeiss. It's incredible.

    Matthew, thank you so much for your review. It definitely gave me the confidence to make the purchase without renting first. Now I just need all of the stores to have it in stock.

    Yes. Are you hoping that it offers some sort of extra focal range that can get you to a wider crop factor than 1.5x? In my experience, not really. If you're just recording timelapses at 1080p you might be able to squeeze a 24mm FOV or so out of it, but that would still require shooting at 18mm or 20mm and cropping in.

    I'm more hoping to have a more utilitarian lens that I can possibly use in the 24-35 mm range on FX without too much vignetting as well. I'm not looking for a wider range.

    Yes, that's what I'm trying to say. You could achieve the EQUIVALENT of 24-35mm on full-frame, but you might have to do it by zooming the lens a little wider than 24mm and cropping in post. This won't be a problem on the likes of a D800 for still photography, but on something like a D700 it might be only worthwhile for lower-res stuff like timelapses.

    Honestly though, I'm fully expecting Sigma to release a fast wide angle full-frame lens within the next ~6 months though. If you're already solidly in the full-frame camp and not interested in things like the crop mdoe on the D800, then I'd hold out.
