Hey guys sorry I know I haven't been on in quite sometime. But I do have a question and maybe someone can help me decide.  Now before I go on I know this is a pretty popular question and I have searched and racked my brains out.  So here it is. In this life of new fatherhood 18 months to be exact.   Lol I see things getting challenging with trying to photograph my daughter running a mock.   When she was 6 and even 8 months I had all day to focus lol she wasn't moving very fast. So now here is my dilemma.   When im out and about with my family I generally use my sigma 18-125mm .. It did its job but as my skills enhance and my daughter gets faster lol I need to upgrade.  Here is what im looking for
my budget is about 600.00 +/- a dollar or two lol
I would need something sharper then the sigma even stopped down its not great
I would like some sort of zoom I was looking at the 18-135 or I think the other was a 17-55 not sure.
It doesn't have to be a canon lens but needs to be EF
Doesn't need to be USM
F4.0 would be plenty fast enough

Now if someone could recommend something that would be awesome. Bc trying to change lens while trying to capture a moment has proved pricey already :-(

I do know that going with something like 18-135 I will be given up some picture quality for zoom but Aslong as its better than the sigma

Thanks
John

Not to be fussy but I think I might want something on the wider side.
But that's a fine piece of glASS lol

Some lens in addition to the
18-135
And 17-55

Are 17-85, 28-105, and the 28-70 non l glass cousin

Any thoughts on these?  Like I said it doesn't have to be canon glass but from I gather its prolly in my best interest to get canon glass

That's the problem im having with the sigma
I love everything about it size, weight, zoom range, speed at 18mm f3.5
I always shoot at iso 100 and this lens produces some noise and not sure of the technical term but even on a tripod at the mid to long focal range  Edges of objects never seem to be sharp.

Im really contiplation the 18-135 or 28-105.  Id be happy with a 17-85.

Hopefully someone can shed some light on this lol

I saw on ebay a used 17-55 sell for 585 last night so there outthere

Its just when u look up reviews they always seem biased id rather have one of the guys from the forum tell me what they think ;-)

Is the 15-85 a good lens?

Well first thing skier thank you for posting bc I tried sounding smart and meanwhile sounded dumb.   Smh

I always thought ef stood for auto focus or something to do with it.  I guess I should have just stated that lol. 

So as a correction I don't care what glass it is or who makes the lens lol I just don't want a lens like my fisheye where it wont autofocus.  Manual focus is good for the fish eye... not good for a kid running around in circles lol....

Getting back on topic that lens seems like just what I need ... is it sharp to your liking ... don't get me wrong everyone liking would be a 5000canon body full sensor with 4000 l glass lol

Wow great pics.... thoselike almost convince me to buy it lol... but im still gonna hold for more advice

Its the best overall lens I have.
I think its as sharp between 18-70mm as the niftyfifty, only softening off at the extremes.
I really find the 15mm useful too.
