Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon SX610 HS is significantly lighter (708g ) than the Nikon P900 which may become a big advantage especially on long walking trips.
Unfortunately neither Nikon Coolpix P900 nor Canon PowerShot SX610 HS provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon P900 and Canon SX610 HS's LCD screens has the same diagonal size of 3.00".
On the other hand, Nikon P900 sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Canon SX610 HS's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P900.
