What is the next lens to buy for T4i/650D?

Hi,
My gears are Canon T4i/650D , 18-55 mm II, 50mm 1.8, 55-250mm, 40mm 2.8 and 430EXII speedlite. What is the next one to choose? And why?

Thanks

What kind of photos do you like to take? What's your budget? And what in your current setup is limiting you? Hopefully those questions will help you decide what comes next

budget $700-800. For purpose I haven't really thought of that.. but mainly sharp picture. and use it for long time.

EF 70-200mm f/2.8L IS II
Why? because you're itching to spend $$$.

HA HA HA.. maybe !!

I don't shoot landscape a lot.. it is just that when I take pictures of family and I like wide background

Maybe one good do-everything lens ....Canon 15-85mm IS EF-S USM ...

The new Sigma 35mm f/1.4 is a sharp lens but it's a little higher than your budget.

What parts of your photography do you find the most rewarding and/or challenge ?

Or what kind of photography do you find inspiring ... "wow that's a great picture , I want to take pictures as good as / like that" ?

Sigma 8-16 or Canon 10-22. Your only "lack" of lenses is on wide angles.
But you're only wanting to spend money.

Canon 17-55 2.8 because its an amazing lens on a crop camera. Great IQ, IS, and ring USM with 2.8 all the way. Get out of the kit lenses and move on up to quality lenses!

This. It should cover just about all common "family" shots. And the IQ is excellent.

It is not that I want to spend.. it's because I am trying to get good shot and I assumed getting out of kit lens might make a lot different. I am not saying that all pic that I took are bad. But when I want to get good shot it sometimes doesn't come out well.. for eg: I was trying to take quick shot at the kids school's event and when I checked it at home, some were blurry and some were ok few were good. I was using the 40mm f2.8 lens at the event. That's why I had this thought of buying new lens assuming to get good pictures.
Maybe I could use some pointers on how to get good shot with my current lens. I am a beginner and this is my first DSLR, that's why I was asking for some pointers on the settings.
Thanks.
