Canon wide-angle lens patent price

Basically, the most suitable one is Canon's 17-85, about 3000 yuan or 17-40 5000 yuan, but these two wide-angle ends are only 1 mm wider than your head. 10-24 super wide angle, you must change the lens. What are you dissatisfied with? Is it not long enough or wide enough? If it is not long enough, 17-85 should be about the same. If it is not wide enough, there is basically no way. At present, there is no pan/tilt from super wide angle to medium focus, unless you go to Quan Huafu on 24- 105.
