Not necessarily - a lot of them are made to end at 24mm to mesh with the next lens, a 24-70 or 24-105.

I only know two: Nikkor 14-24mm f2.8 and Sigma 12-24mm.

 

The normal UWA's have overlap (thankfully): 

Nikkor 16-35mm f4 VR

Canon 17-40mm f4 USM

Canon 16-35mm f2.8 USM

Nikkor 17-35mm f2.8

Zeiss 16-35mm f2.8 SSM

Tokina 16-28mm f2.8

 

On APS-C SLR there are only two examples of lenses with less/no overlap (depending on which APS-C standard zoom to put them next to), the Tokina 11-16mm f2.8 DX and the Sigma 8-16mm DC.

Pentax and Tokina 12-24's also.

 

The other UWA's that you list are for FF.  They are not really UWA on APS-C.  The 12-24's are 18-36 FF equivalents...to the lenses that you list.

[dave9t5]

Yeah, the focal length range is a bit odd -there isn't a matching 24-xxx lens. Of course, a user might want to skip a midrange zoom altogether, and go for the 35/1.4 and a Tele lens.

 

My thoughts too.  10-24 and 55-200 covers alot.  But I do 80% of my shooting with a 15mm, 28 and 58mm primes...don't need to have every single focal length available.

[Klaus]

Well, take the Zeiss 12mm or Fuji 14mm instead. The choice is yours.

[stoppingdown]

The discussion of overlap makes sense in a different perspective: other lens catalogs offer more choice and you can choose whether you want a set which overlaps or not. Indeed the overlap can be helpful (more flexibility, as sometimes you don't have to change lens), but with a price to pay (heavier). Currently with Nikon I have an overlap (12-24 + 18-70) but I'd like to go with the lighter solution without overlap as an alternative. In other words, with Fuji, I'd like to see both a 10-18 (such as Sony's) and a 24-70 or such.

Those are APS-C lenses. The 24-70's are FF lenses. We were talking FF lenses in this APS-C thread.

As is this 10-24. Speaking of this focal length: there is a Nikon and a Tamron sharing it. And though the 24-70 lenses are full-frame, they make sense on APS-C as well when coupled with a xx-24 lens. A few people I know were using this kind of setup.

 

If I'd been shooting Fuji, I would've taken the 10-24 + 35 + 55-200.

That is fine, but the 24mm overlap mentioned was meant in FF terms. The 22-24mm ends of APS-C UWA zooms are not designed to match FF standard zooms.... They merely mimic the UWA zoom range of FF UWA's.

[Rover]

Regardless, they mesh well.
