Default Kit lenses or Tamron 18-270

I have the Canon T2i with the 18-55 and 55-250 kit lenses and I was wondering if the Tamron AF 18-270 would be better or worse than what I have now. The other lens I'm looking at is the Canon 18-200 IS. Any recommendations would be helpfull.

The 2 lens are actually optically better then the 18-270. But the 18-270 for a megazoom lens is one of the better ones out there. If you want a fast focusing and smaller travel setup. The 18-270 PZ is one of the best you can get. It is better then the canon 18-200.

While neither your kit 18-55 nor your 55-250 are particularly good, they're better than any jack-of-all-trades-and-master-of-none lens. While you won't have to change lenses anymore, the image quality won't be as good as what you're getting now.

If I were to replace these lenses with two other lenses with about the same focal length what would you recommend? I want to get the sharpest pics without breaking the bank. Maybe I'll replace the 18-55 first and then save for the 55-250. The two lenses I have now are borrowed from my dad. He has the 18-200 so he doesn't use them but I'd like to get my own.

Around $400 to replace the 18-55 and $700 for the 55-250. I shoot all kinds of things but wildlife is my favourite. I find trying to choose lenses really cofusing. Everybody has a different opinion. Some people say the lenses I have are just fine and others say to get rid of them because they're crap. It's hard to know what to do.

canon ef 70-300 IS USM non L or tamron 70-300 VC USD to replace the ef-s 55-250 IS. And if you do not need IS or as much reach. The ef 70-200L non IS is a good one.

on the 18-55, with that budget the sigma 17-50

The 17-50/2.8 shoturtle mentioned is a good choice, but so is the Sigma 17-70/2.8-4.0.

Also, if you don't really need the wide end of a standard zoom, the Tamron 28-75/2.8 is very nice and in your general price range, though it's not stabilized.

As a walk-around lens, I have been pleased with the performance of the Tamron 18-270 VC (on a Nikon body). At apertures around f8, sharpness is excellent (and I am a pixel peeper at that). Look at the samples under the username "Wingman" in the following thread: Tamron 18-270 DII VC PZD or Sigma 18-250mm?

The lenses you have are just fine...they are just not pro lenses that have large constant apertures, or are optically sharp at maximum zoom and at aperture extremes. Lenses that fit that bill cost thousands! The advantage to a lens like the Tamron (or Sigma 18-250) is that it saves you the trouble of switching out lenses. I also own a 70-200 f2.8, but I use it for aviation photography exclusively.
