I´d highly recommend you 55-250mm IS STM. Can be found for peanuts, and is awesome and very sharp.
I'd reserve "very sharp" to non ef-s and non 5x+ lenses. L lenses and good primes are very sharp. Usually is those that don't have better lenses that say the low end zooms are very good!
do you count the 70-200F4L sharp?? 70-200 f4L vs 55-250 stm
That's a non 5x+
do you count the £2500 GBP 11-24 f4L sharp EF-M 11-22mm vs 11-24 F4L
So is that.
So we need to know whether Red Fox 88 meant that both conditions cited were individually necessary for a lens being "very sharp". As stated, his post suggests that a lens has to be non EF-S to be very sharp, and it has to be non 5X+. Therefore a single very sharp EF-S lens, no matter the zoom range, would count as a counterexample. But perhaps he meant that lenses have to be non (EF-S and 5X+) to have a chance at being very sharp. In which case, what he said is consistent with an EF-S lens being very sharp, so long as it isn't also a 5X+ zoom. It's a matter of the scope of the negation (in technical logical terms).
And yes, I know this is very pedantic. It's actually my job to be pedantic (I'm a professor), and logic is one of the subjects I'm qualified to teach. At least I've given you something different to be annoyed at.
do you count the 17-40 F4L sharp EF-s 17-55 F2.8 vs 17-40 F4L
And that.
do you count the 24mm F1.4L sharp
From the above, yes.
The EF-m 22 f2 is at a big disadvantage as the L glass is on FF+ more MP but the 22/2 still puts up a good show EF-M 22mm F2 vs 24mm F1.4L
Pretty sure that counts as a good prime?
+1 to Crash's suggestion (unless she wants to go as small as possible). Great lens, though she'll need to pair it with another for the wider stuff.
