16-80 zoom affects review speed.

[Pixel8r]

I recently acquired a used 16-80 zoom from my favourite camera dealer. When I shoot at or around the 16mm end there is a short delay after pressing the review button before the image appears. When I shoot at or around the 80mm end there is a delay of almost two seconds before the image appears. It doesn’t sound a lot but if it is not normal I wonder if it could be a faulty lens. So I just wanted to ask if any of you get the same results. I use it on an X-T3 and have tried it on an X-E1 and get the same results. Thanks.
