Bearing in mind I already have an EF 50mm f1.8 for indoor and sports photography.
For general photography in urban and rural environments, I can't decide whether to get
A: Canon EF-S 18-55mm f/3.5-5.6 IS II £100 + Canon EF-S 55-250mm F4-5.6 IS II £130
B: Canon EF-S 18-135mm f/3.5-5.6 IS £235
C: Canon EF 28-135mm f/3.5-5.6 IS USM £280
A obviously has best focal length range and larger apertures at portrait and above focal lengths, but is less convenient than having a single lens, question is whether the single lens will necessarily have enough reach in some situations. B and C will definitely be more convenient and probably have enough reach in 80%+ of situations. C obviously has a USM but is not as wide which may become a concern in certain situations again, not sure if it's worth the money above the other two.
