I sold my xc 50-230 in favour of 55 200 xf, for the extra weight and price, you get better build, better image quality and contrast. People are complaining about the extra cost for one stop of extra speed, which is about €300 with this lens, but not complaining about a 50mm 1.4 lens being €300 dearer than a 50mm 1.8, also one stop. It comes down to as it always does, you get what you pay for. If you can afford the 50 - 200 and will make full use of it then its the way to go .
