fill the void -17mm to 24mm

[NWPhil]

No such beast yet.   I'd say keep the 17-40 and keep saving for one of the high end primes.

+1 Why does it have to be a prime? Both the 17-40L and 16-35L are fantastic wide angle lenses. If you're ebing limited by the 17-40L, maybe try the 16-35 instead?

Or perhaps the 14mm or even the 8-15 (fisheye)

Nice choice of lenses for sure, but for 'filling the void between 17mm - 24mm... surely not really going to be contenders here?

agreed - the 15mm is already a special use lens for me - it travels always as a secondary lens

I'd say pick up a 17-40. Doh 

I think the 17mm TS-E is your only choice if quality is factor #1.  I have it and it is an awesome lens.  Check eBay, i bought mine used for $1600.

starting to agree with that more and more...
great deal at $1600 - new: they show from $1895 to...overpriced, and not many used in the last few weeks.
I think I saw one about $1800 - used

I've been through this as well and I have the added issue of being an unbelievably bad auto focuser - even with a lens that wide. I know everyone will say "it's all in focus with a wide anyway but not for the type of shooting i'm doing where I generally have a model or some other subject in the fore frame.

I shoot with the 35 L primarily - own the 15 fish and sold the mark 1 version of the 16-35. I've had extensive chances to play with the new one and it's ok. NOT STELLAR. Someone else asked "why primes" and the answer as always is weight, aperture, and generally better performance. I have had many talks with Canon reps about the fact that (until the non-AF and super expensive 17 TSE) there is no L prime between 14 and 24 and that an 18 or 20 would be a welcome edition. F 2 perhaps...1.8 on the 20 end would be pretty sweet.

Sigma makes one that is reasonably sharp but honestly focuses slowly...

[NWPhil]

took a look at that sigma - the reviews give it low ratings
17 TS-E is indeed the better/best option for overall performance and view angle; that is, if you want that wide
maybe I can sell a kidney and then buy the full line of TS-Es...but I would have to drink less beer and wine - darn!!!

maybe the Zeiss ZE 21mm f2.8?

That's an awesome one, I'm having a tough time deciding between that and the 24L II.  I really only used my 16-35mm for the wide end and with the 14mm it seems unnecessary, so I guess I'm going to sell it for the Zeiss 21 or 24L

if you thinking indeed about a 24mm -------take  look at the TS-E. I did, and will not look back
Zeiss 21 is a great lens too, according to reviews...and then there is the other TS-E (17mm)

I've actually never played with a TS-E, do you enjoy yours that much?  I always thought they seemed pricey and somewhat limited in terms of functionality.  If you don't tilt and shift it's just a plain 24mm right?

I really like mine.  For architecture, there's really no substitute. For landscapes, tilt is great.  It's also a lot of fun just to play around with DoF effects. Without TS, I suppose it is just a 'plain 24mm' lens, and manual focus at that - but it's the sharpest and least-distorted 24mm lens you'll find.

it would be a waste to 'just' use it as a 24, because has so much more to give.
I never tried the 24efII, but I really love the 24 ts-e. Next upgrade I will make will be the TS-e17mm
Still think Canon is missing something between 14 and 24 as worth consideing prime - they can't/won't ever have every number in between(as prime) but seem logic that they should consider a 20mm (1.8?) or whatever they can make with low CA and soft edges
Zeiss has the 18 and 21, altough the 18 is a lesser performer - so there you have it 19-1/2

Sorry no other options:

1st choice: TS-E 17mm L
2nd choice: Zeiss Distagon 21mm f/2.8 

I have the later and I wish the former

If you do not want your zoom you sell it, add the 1000$ which is your budget and you are closer to
get a wonderful lens...
