Sigma have just released this new lens

http://petapixel.com/2013/04/18/sigma-drops-bombshell-announces-a-18-35mm-f1-8-lens/

What do you we think?

At present its an APS-C lens which is frustrating as most of us will use full frame.

Would a primarily "landscape" lens really need to go to 1.8?

Seems to be the next step in lens design

The size & weight of a full-frame equivalent would be almost unbearable to use (or at least I'd imagine it would).



I disagree this is a landscape lens at ~28-56mm equivalent (full-frame) as typical landscape lenses hovver either side of ~20mm equivalent, this would however make a very nice general purpose lens being able to shoot at ~56mm equivalent which could do 3/4 shots of people for fashion/glamour and could go wide for location shots.  I'd seriously think of buying one of these if the price is reasonable (say £7-800)

It's a 27-52 FF equivalent so a sort of general purpose, even photo journalistic ( street photography) sort of lens with such a large aperture, and no image stabilisation. A 'landscape' lens does not necessarily need such a large max aperture but Sigma are obviously trying to maximise their sales potentials. If its performance is near the 35 mm prime 34 f1.4 it will be a useful piece of kit.

Sigma has a track record of launching unusually fast but not particularly good lenses - there was a range of f/1.8 wide angles (20mm, 24mm, 28mm) that were well-specced but otherwise pretty poor. On the other hand the MTF graph looks impressive, and Sigma seems to have turned a corner over the last couple of years. I'm surprised that there haven't been more of these "killer app" lenses for APS-C cameras.

It would be a fun party / club-type lens although a longer range would be even nicer. In my opinion an image stabilised APS-C 40-135mm f/1.8 that can focus closely would be even more awesome as an APS-C lens (it would be an almost direct equivalent of a 70-200mm f/2.8 in full-frame terms, with similar depth of field).

If I recall correctly the previous record-holder was the old Angenieux 28-70mm f/2.6, a full-frame lens of almost mythical stature.

As per my comments earlier, such a lens would be excessively heavy, even more so considering most crop bodies are not only small but generally plastic so it'd make an incredibly unbalanced lens on one of those cameras.  When you also consider the cost of such a lens (which I'd guess would be high) it wouldn't sell, especially since I'd imagine most crop body owners are simply after a bargain.

+1 Sigma actually make rather good lenses these days, as many who have bought one, will tell you!This sound like an interesting lens!

You'd kind of hope that an '18-15mm' lens would be f1.8 across the range! That must be the shortest zoom lens ever made in history!!
