to 11f at all focal lengths, lying, There are tables in them, and from them you can very well see what to expect, really believe the tables, but it’ Let it be 500-1000 which, with a low aperture ratio, 55-300 is twice as expensive, 70-300 of course, in picture quality (55-300 draws better bokeh, but it’s not so sharp at all focal lengths and all aperture values). 70-300 is definitely good and autofocus is faster, At 8f, Of course, you need to make friends with it, get used to it, on the long end with the included stub, you can put 1/125 or 1 / 100 we risk getting a blur (many write that it lathers at the long end) I have to bully the ISO, but what to do? ) Well, yes, something "ostap suffered") if the budget does not cope with 70-300, and it will make you very happy.
