I haven't used the EF-S15 to 18, but know a Bloke who does and he loves it. Araldited* to his 7D, I think. From what I see (and read) it is like the EF85/1.8 - "excellent value for money, great IQ, one of Canons ‘sleeper’ lenses in the economy range". (*Dunno if Araldite is available in Canarda - it is sticky stuff the bond is very difficult to break once it is set.)
Not sure whether you meant that the existing 15 to 85 should be an L Series Lens or if you meant that you’d like Canon to make another L Series lens in that zoom compass with an EF-S mount:
Another oddment which is not often realized is that: third party APS-C specific lenses made to fit Canon EOS Cameras (i.e. those with an image circle specifically for APS-C Cameras) are all EF Mount Lenses: often incorrectly referred to as EF-S Lenses, these third party lenses will mount and will work on all canon EOS cameras, often with varying degrees of optical vignette at various Focal Lengths, but nonetheless useful in an emergency.
(Back to Dual Format Kits) – having decided that all our Studio kits (four of them, initially) would be Dual Format; considering we were looking at a reasonably large Capital Expenditure, I really had to sharpen up my accountant’s pencil when it came to the Lens’ Inventory. I decided that meant absolutely no room for any EF-S Lenses – for several reasons the main being it would be fiscally irresponsible to invest Capital into any tool which could not work on ALL and ANY camera at hand.
There was a time when I was really was tempted to buy two EF-S 17 to 55F/2.8 IS USM lenses for the Studio Kits. I used this lens extensively and it is a very good lens; but I am glad I didn’t buy any because whilst very good it is not an inexpensive lens
