No idea. I just meant that the outer surface of the front element is exposed (duh!) regardless of any internal sealing, so it helps if the lens cover is watertight.

Sure, but I always thought the weak link w.r.t. sealing with the front element was the filter threads. (True?)

If a lens like this doesn't have filter threads, why not gasket the periphery of the front element and declare that path of ingress as being sealed?

I also wonder if zoom range obsessives -- the folks who have always been miffed about 16-35 and 24-70 overlap -- would jump on this as a new 'zoom trinity' of 14-24 / 24-70 / 70-200 like the Nikon camp?

What say you all?  Let's say:

  • You did not presently own any UWA zoom
  • This new Sigma is on the very high level of the 16-35 f/2.8L III and the AF is spot on.
  • The price / quality of the 14-24 and 16-35 lenses is the same. (price surely won't be, but let's just say so for the sake of argument)

...would you prefer 14-24 / 24-70 / 70-200 or would you prefer 16-35 / 24-70 / 70-200, and why?

My Tokina 16-28 is on permanent loan to a nephew, so I guess I qualify.  I have nothing between my 14 and 24mm primes and I like 14mm wideness.  So 14-24 is more desirable to me.  The purported low distortion is (potentially) icing on the cake.

16-35/24-70/70-200 because they all can take filters easily.  My most used focal length is 35mm, so having two lenses getting me to that focal length means significantly fewer lens changes.  That... and the 16-35 is lighter/smaller than the 14-24.  The 11-24 and 12-24s have been around for years now, but I'm guessing the 16-35 is a more popular lens choice.  With the 11-24/12-24s , the 14-24 seems superfluous, but it looks to be aimed directly at Nikon.

100% agree.

Disagree.  With the exception of their line of lenses just for mirrorless, Sigma doesn't put out glass without a strong Canon sales opportunity -- they'd be fools not to with Canon's market share.  I think there are still some Canon folks who have always wanted that 14-24 Nikkor and Sigma is hoping to scoop them up.

Also, going down to 11mm is brutally heavy, expensive, exceptionally challenging to filter, and -- perhaps critically -- is f/4.

I guess that there is something magical to some folks here about 14mm + zoom + f/2.8 being all in one lens.  It's not for me as I said before (the wheels come off the bus for me without a front filter ring and compatibility with 100x100 / 100x150 filters), but this was for a long time high on the list of lenses Nikon offered that Canon did not.  I'm guessing that's what Sigma is banking on here.

Very interested, but will wait to see just how go it is

Does Sigma offer a service to convert between mounts?  Just curious

Here you go:

Might cost $300 or so.   Could be a toss up vs selling the old lens and buying a new in a different mount vs converting an existing lens

this a cruel move....

I have Canon 14 mk II .... the lines are straight and pretty sharp in middle...with chromatics
it is a nice small lens .. and keeps a 5Dx size ...smaller

then the Tamron 15-30   a bit of distortion at 15mm... but so very sharp.. towards the edges.. and stabilized..
now they torture us with this one.. I wonder how large it is

I guess..
I await the Canon 135 I.S. ... and stall on all these great options... that keep coming..

////

I didnt even know what it was like to shoot 'wide'  til Canon made the 10-22 ef-s for my 20D...

all I used on a visit to chicago....

then I was hooked..

cruel.....but a lovely idea...

As someone who owns both the 11-24 and the 16-35 I would comment horses for courses.  As mainly a landscape shooter the 11-24 is invaluable and I can't think of a time I have needed faster than f4 for that range.  If I need fast and wide I go with the Sigma 14 f 1.8 prime (astrophotography).  If I need light and not as wide and easily filterable I go with the 16-35. 

I admit I have lots of overlapping glass in this range but each serves a purpose and I often carry at least two when I go into the field.  The 11-24 always requires the most consideration to bring along as it is difficult to shoot with that wide, the filtering system is a beast and it is heavy, but man, what a performer when you get something good! 

Also, I shoot a lot in not ideal conditions (mist, ocean spray, fog, wind, etc.) and have never had problems with my 11-24 with WonderPana on the front.  I don't shoot in pouring rain, but not sure what shot I would be seeking on those conditions regardless. 

Just my response to your question.  Bob

I, am pretty lucky.  My WA array is a wonderful 14mm f/2.8 ii and a 16-35 f/4.  The thought of carrying a 14-24 zoom instead of 2 lenses is appealing but not right now.  Need to finish paying for what I have  ;) .
5d MkIV; Eos-M5 and too many lenses; 430 EXii, 430 EXiii-RT, Flashpoint V860ii-C and a lot of stuff.

Curious how and why this lens is better at 14mm than the prime f/1.8. Especially distortion?

The rumor in December wasn't about two Sigma 70-200?

Biggest obvious upside is that it zooms.  Some vistas don't allow you to move your feet to fill the frame.

Also, it being a zoom opens up a host of other use-cases:  events, sports, etc.

But Sigma is claiming less distortion than in the prime.  How do they improve it and AF, etc at 14mm in a zoom?

funny, this one should have 0 distortion, as should have the 12-24 f4. but the 12-24 is reviewed with lot of distortion by the reviewers (Lenstip and TDP)

So, very reliable information on the sigmaa page, hopefully aat least the price is reliable

My fault -- I only saw the "why" and not the "how" in your question.  No idea how they pulled it off, or even if they did.  (I seem to recall Laowa making a similar claim and reviewers didn't find it to be so distortion-free.)
