Used to have 10-22 and 24-105 on 50d but found myself switching back and forth between these lenses too often! It might sound good to cover the whole 10-105mm focal length range without too much overlap, but it didnt work for me. A key reason for me upgrading to FF was that the 24-105, which I love, would become much more useful (24mm was not wide enough for me on crop sensor).

I recommend the 24-105 if you're planning to upgrade to FF and can live with less wide angle on your crop camera for a while. You could also consider adding the 17-40 which is reasonably priced and takes care of the wide end on crop and it could later serve as an ultra wide on FF.

If the light is so low that the AF is being affected I would think the 60D would be struggling anyway

No, this isn't the case - when using iso800 or maybe iso1600 with a lens with IS, the 60d works pretty well even in lower light with reasonable iso noise. It's just that focussing @f5.6 isn't very reliable in these conditions.

When using single-point af, I'm used to shoot 2-3 pictures and then dump the out of focus ones. It's better with multi-point af, but sadly there are too few af points spread too far apart. This is where the 7d should shine, but alas, it doesn't run magic lantern :-(

I was suggesting the 24-105 which is F/4 which I believe are as good as f/2.8 on the centre point?

I wouldn't suggest the 15-85 for a variety of reasons

I don't really know how large the difference between f4 and f2.8 is concerning af performance on the 60d, but I can say f4 is good on my 70-300L in non-optimal light. But if regularly shooting something you cannot take multiple shots of, I guess getting f2.8 like on the Tamron 24-70 for safety isn't a bad idea - for tele lenses, it's just that the 70-200/2.8 was too zoom-short, expensive, physically-large and heavy for me. And a good af like on the 5d3 should do better anyway.

Concerning 15-85 or 24-105, it's really a matter of "do you need the wide angle" or get another ef-s ultrawide, and if sealing is important for the environment the lens will be used in. And last not least, let's not forget the 15-85 is way cheaper than the L and should give comparable performance in most situations.

Which is why I suggested buying used 24-105, there are plenty around

I use the 15-85 with my 7D and the 24-105 with my 5DII.  Both work excellent for walk around purposes.  Never even thought of using the 24-105 on the 7D.  I do like my wide angle though.  I would recommend the 15-85 for a crop camera.

I sold my 24-105 after getting the 17-55 f/2.8. I found it was just not wide enough on my 7D. The difference on the long end is not so noticeable as I also have a 70-200 in my bag, and the gap in focal length between the two lenses I have not had a problem with at all.

I find the 24-105 covers the portrait lengths on a crop whereas the 17-55 is too short and the 70-200 is too long (and visible for street work)

I see no reason to own the 24-70 or 24-105 on a crop body with the 17-55mm around. It is as sharp slightly lacking range but is fast and has IS. Only thing it misses is weather sealing, had mine in all sorts of conditions, soaked dry etc only thing is it does suffer a little with dust but chuck a UV filter on the front should reduce this.

Reason for my opinion is I did the same thing wanted to go FF in the future so got a 24-105mm and it was great on the long end but constantly switching lenses for the wide what do you combine it with? The equivalent focal length is 38.4-168mm, combining it with a 10-22 there is a huge gap. Buy a 17-40mm in between equivalent of 27.2-64mm  Dont get me wrong the 24-70 and 24-105 are incredible lenses but the dedicated EF-s lenses are more suitable. so 3 lenses for a standard focal range... then you need a tele because 168 is ok but not that far so a 70-200mm equivalent of 110-320.

I decided to sell the 24-105mm got a 17-55mm had the 10-22 so that filled the standard zoom range. Also had the 70-200mm so there was a gap on the other end between the 55-110 but depends what you shoot I dont shoot portraits really apart from the odd wedding so filled that with a 50mm which is 80mm equivalent and I tend to shoot on the wider side.

Also the 17-55mm are high in demand, buying one and selling it you shouldn't loose too much money. Most are selling second hand in the UK for between £500-£650 depending on condition.

If your moving to FF then sell it and change up to the 24-105 or 24-70mm. I think that the only FF lenses worth having for a crop body are the teles 70-200 and everything above, the 100mm L or non L macro, TS because there is no crop equivalent For wide and standard the crop sector has it covered, the 17-55mm and the 10-22mm are a fantastic combination. The standard and even the wide full frame lenses are not wide and offer a strange focal length meaning you have to learn to shoot in an unfamiliar way.

My kit fills most of my need for crop, the obvious drawback is to sell the lenses which is an inconvenience not a deal breaker.

10-22mm
17-55mm
50mm = 80mm
100mm L macro
70-200mm

Suits my style but would be nice to have a medium tele in the range at events but they dont make a fixed aperture just the 15-85mm try to stay clear of vari aperture lenses.

If they made a 15-85mm 2.8 I would be all over it but they wont, im guessing because it would sacrifice all the other lens offerings although im sure the price would make your eyes water. Plus not many pros shoot crop for everything more for the tele end and reduced cost of lenses so less need I suppose.

Best case have a 7D for length 5D MKIII for everything else.  8)

...

The 1.6 crop factor also needs to be taken into account with EF-S lenses, e.g:

10-22mm corresponds to 16-35mm FF FOV
17-55mm corresponds to 27-88mm FF FOV

In other words, there is a negligible 2mm gap between the 10-22 and 24-105, and a small 15mm gap between 17-55 and 70-200 on crop cameras.

Ive used the 24-105 on my 7D for a couple years and lkve it as an all around lens...Def use a true wide for landscapes but thats not really a walkaround situation. Now on my 5D3 the lens is perfect. Well close,  a 2.8f version would be killer, but then the 24-70 wouldnt be needed. Ultimately get it. Its a pro lens. You wont regret it.

I used to have a Tamron 17-50 f/2.8 nonIS on my 40D and 'upgraded' to a 24-105L and have no regrets at all.

My lineup on the 7D  is 12-24 Tokina, 24-105L as a walkaround, and a 70-300 as a Tele, I have the 24-105 for universal use, on a very rare occcasion as a portrait lens at ~105mm (nice OOF) but for dedicated portraits it does not beat the primes at 50mm or 85mm.

For the price the Tamron is a great deal, maybe you keep it for your wife's 450D,
the 24-105 may be useful on a future FF body, too.

Examples?

I *loved* the 24-105 with my 7D... Was my main walk-around lens. Paired with a 10-22 or 12-24, there is NO problem with the 24mm widest FL. IQ was excellent from end to end, very happy with that combo.

On FF the lens gains a little more use on the wide end, but I do miss the reach of 105 with the 7D.

For a while I used the 17-40 and 24-105 on two crop bodies (7D and 50D) as my regular setup. Since purchasing the 14mm and 50mm L primes I have used both primes a lot, especially the 14mm. Since then I rarely use the 17-40, but the 24-105 I use quite often. Having some nice lens for wide angle complements the 24-105 quite nicely and indeed I am using it often at 105 as well, without feeling the need to switch to my 70-200 all too often.
