A little while ago I was considering changing my camera to ease the problem of carrying all the equipment on my bad back and neck. After much thought I have decided to keep my Canon as I really like it, but try to reduce weight wherever possible. 
To start I have  changed my 100-400mm Tamron lens which really was excellent, for a Canon 100-400mm RF which is approximately half the weight. 
Today Mrs K, Jak,  and I took it for a local walk.

A very happy new year to you all.
