Haiyoh 80D with 18-55 is purely nonsense.
The 80D you have to match with Canon 15-85 and 17-55 only good.
All the rest are just holding back its performance. No just IQ but the 80D's superb AF system.
And please, DO NOT go 24-105L unless you are pretty damn sure you can live with that less wide nature of it.
If you want to know how wide is the 24-105L on 80D, twist your 18-55 to 38mm. That's the starting WIDE on the 24-105L.
Can live with that? OK then you're good. If not then you're in for a shock.
If you have a certain focal length that you like and want image quality, go with a prime lens.
EF-S 15-85 is available for around RM 1.3k - RM 1.5k range. Good lens there, not constant F4 but it works like a 24-120 and it has improved optics and image stabilization over many Canon's older lens. If you insist on wide constant aperture and not willing to cough up more money then look at the Tamron or Sigma 17-50 models.
