Sigma announce 18-35mm f1.8 lens...

[Rojin]

Crop only, but quite interesting depending on price...

That looks very interesting.
As you say depending on price though,(probably around the £1k mark) but also build quality & sharpness.
Look forward to reviews on this.

Crop only. Bah. Although, I want then to announce a 14-24! (Or canon too)

That's very very cool. If it's in the league of the 35 1.4 then it'll be a right stunner, nice to see them experimenting with their own lenses (other than the bigma) rather than just filling out a line to take on Canikon at every turn. It was never gonna be a full frame lens, come on guys, but still a very cool piece of glass if they can pull it off.

It makes me wonder what the possibility of a 24-55 f/2.0 type lens would be..

 

[Columbo]

This could just about the perfect zoom lens for me.

Nice to see Sigma doing something new and thinking outside of the box.

 

[Logsi]

Will probably have nervous bokeh... :roll eyes:

I got really excited until i heard crop.

Perhaps it might be ok in 1.2x crop mode.

Interesting to see someone doing something genuinely new in a market place that has become a bit stagnated by incremental imporvements and massive price hikes.

If it's any good it will be interesting to see if Sigma try and bring something similar to full frame as that could be really interesting.

Would also like to see sigma sort out some of the dogs in their line up, it must be time for a 24-70mm OS HSM to compete with the similar Tamron?

 

[D.P.]

Very interesting lens, would like to see the wide open performance. Sigma make a lot of unusual lens (120-300mm f/2.8, the discontinued 100-300mm f/4.0, 150mm f/2.8 Macro, 20mm f/1.8, 12-24mm FF, 8-16mm crop).

But there success rate with these lenses is mixed. 20mm f/1.8 is dire (as is their 24mm f/1.8).



Anyway, if it is sharp wide open then it will close the gap between FF and crop cameras. Compared to a 24-70mm f/2.8 you've lost some range but completely erased any difference in DoF and light gathering ability making an equivalence.

If it is anything like the Sigma 24-70 then the bokeh is probably not very pleasing at all. :roll eyes:


This is going to be an extremely complex lens, wouldn't bet money on having creamy bokeh like the CaNikon f/2.8 zooms.

Come to the Darkside we have the 14-24.

 

[Ksanti]

1.2x crop is already pushing it

Me too. Will be pricey though.

 

[Rojin]

Sharpness looks good on the wide open shots:

[Devrij]

That's quite exciting. It's be nice to have a fast versatile lens like that.

 

[Raymond Lin]

I like this out of the box thinking, now make one for full frame!

 

[SDK^]

I don't get this lens.

Sure the constant 1.8 aperture on a zoom is a world first but the focal range isn't useable on a crop body.
For many years people have been ditching the Canon 17-40L on crop bodies because it's not wide enough but now because a similar focal range lens has a wide aperture it's suddenly amazing.

Hmmm

 

[Ksanti]

No, people ditch the 17-40 because it costs the same more than the Tamron 17-50 which is as sharp, is longer at the long end and is a stop faster, for the sake of full frame compatibility and build quality, and then spending that sort of money could well go on the 17-55 which boasts a stop advantage, is as sharp if not sharper, has the extra 15mm and IS. It's not the range that particularly lets down the 17-40 as a crop general lens, but the fact that you're paying for glass and making compromises for it, when you're not going to use the whole image circle.

The Sigma looks to be every bit as sharp as the rest, has over a stop advantage through the range, still makes it through the wide to normal range and will be built better than the lot of them, on top of the momentum that Sigma have generated from the 35mm.

18-35 is a great range for street, weddings, bands etc. but the 17-40 is just too slow. This isn't a landscape lens.

Eh? 18mm not usable on a crop?
Not sure I agree with that.

And people haven't been ditching the 17-40 because of the focal range, people have ditched it because there are cheaper and better alternatives available.
