Hello,
I have recently moved to a Canon 7D II and a Canon 100-400 mk2. The kit weighs about 2.5kg. Not a lot of weight in the scheme of things. My previous camera was a Canon 750D and a Tamron 18-400 lens.

First time use of the camera, my ropey, 70y+ old spine extracted a payment from my body after a walk of only 3K. I tend to carry my camera in my right hand, secured with an over the left shoulder cross body sling. As a walk it is at the lower end of walking distance, I regularly cover 6 or 7K a day. It would seem this camera load may need reducing. There are some structural problems with my frame. A lot of good physio work went into repairs.

I think the Canon combination is ideal for bird photography, however I need to manage my back in some way. My thoughts are running towards a Sony RX10 IV to replace the Canon system. I most assuredly don’t want to give up photography nor walking. Reading posts it would seem the camera/lens weight regularly comes up.

Any RX10 experience or comments please?

Thanks and kind regards,
Journeyman
