Lense suggestions

[Fdmcgady]

I own a Canon EOS Rebel T2i - I have a 10-20mm lense and a 28-300mm lense. I was thinking of getting something in the 28-70 range. I was looking for some suggestions.

How much are you willing to spend, and do you have any thoughts of eventually going to a full-frame camera (e.g., 5D or 6D)?

[Fdmcgady]

I probably will not being going to a full-frame camera any time soon. I was looking for something not too expensive. I've seen some Canon 18-135mm zoom lenses.

Either the Canon EF-S 18-135 IS STM or NANO lenses are good choices.

Avoid the older versions of that lens.

You already have kit lenses.  The kit lenses don't have particularly large apertures.  Your lenses already cover the range from 10mm to 300mm.  

You should strongly consider getting something different from what you already have for your money rather than another variable aperture zoom.  

You do not have a bright fast lens, ie: a lens with a large fixed aperture.  You could do this two ways.

You could get a 17-55 f/2.8, which is a great lens for crop cameras.  This would let 4x the light into your camera at the long end, letting you shoot in dim light with a fast shutter speed without having to jam the ISO up to a level where your image quality suffers.  It is also very sharp.

You could go with even brighter glass, like a bright prime.  Something like a 50mm f/1.4, or an even cheaper 50mm f/1.8.  This would give you a lens that will work in low light and it will also give your shots a different look due to the shallow depth of field you get with a large aperture lens.  Even the 40mm f/2.8 pancake would be brighter than the kits lenses and would give a narrow DOF, and primes tend to be very sharp for comparatively little money.

"You already have kit lenses."

I agree!  Why do you want another? The EF-S 17-55mm f/2.8 IS USM Lens would be an excellent upgrade.

"I have a 10-20mm lense..."

Do you mean and you have the EF-S 10-22mm f/3.5-4.5 USM Lens?  Perhaps the EF-S 10-18mm f/4.5-5.6 IS STM Lens?

In either case the faster EF-S 17-55mm f/2.8 IS USM Lens is still an excellent choice.

I also like the idea of a fast prime.  It will have better IQ plus a fast fixed aperture. Examples would be the EF 50mm f/1.8 STM Lens or the more expensive EF 50mm f/1.4 USM Lens.

I agree with the idea of having a wide aperture zoom, or a fast prime in your bag, like the EF 50mm f/1.8 STM lens.  Make sure you get the "STM" version of the lens.  It is the one with the metal connection to the camera, not black plastic.  In fact, make sure you get STM versions of any Canon EF-S lens, although there are a couple of excellent "USM" exceptions to that rule.  The 50mm f/1.8 STM is a better deal than most photography classes.

If you are looking for a good walking around lens, for capturing photos like a tourist, then the 18-135 lenses that were mentioned are good choices.  Please take note of the fact that "walking around lens" strongly implies walking around outdoors in the sunlight.  Using that lens indoors, will almost require a flash, under most circumstances.

If the Canon 17-55mm f/2.8 is too pricey, then take a look at the Sigma 17-50mm f/2.8.  It seems to be on sale at 50% off, clearance prices, at some major online retailers, and I do not mean Amazon r eBay.  Avoid them both when it comes to camera bodies and lenses.

Thank you everyone for the opinins - that is just what I was loking for. I will start doing my homework now.

I have the Sigma 10-20mm f/4-5.6 EX DC HSM lens

That's what I figured.  You might like Sigma 17-50mm lens, if you cannot afford the Canon. 

Keep in mind that the Canon DPP software is only able to do lens correction with Canon lenses.  If you do not use any post processing on your photos, I suggest that you shoot in RAW format, and give it a try.
