I have a 200-500 and a 70-300 which I use with my D500. I have had the 70-300 for quite a few years now, mainly because it is so light and very useful for travel and has good IQ, if a little soft at the longer end. I'm contemplating buying a 70-200 2.8 VRII to replace the 70-300 in order to gain the extra stop, better bokeh and IQ, although its a lot heavier and more expensive. Cost is not really an issue. I usually buy second hand from the likes of LCE, MPB and Parks Cameras. I have read some reviews that say up to 200mm there's not much difference and also that the 70-300 works well with the kenko teleplus 300 pro 1.4 x converter. So, has anybody compared these two lenses and opted for the 70-200 ?
