1 and 2 do it for me. B+W works well for these

Liking the waterfall pics.

Super stuff gareth

Very nice. Wonderful light.

nice set, the last one is excellent.

Aberdeen seafront gets my vote.

Invented by the Romans I believe. Concrete that is, not Aberdeen seafront.

The problem Vic is the weight and size of the modern lenses. If you turn the ball/pan-tilt head to the side so the camera is in portrait mode, the weight of the lens can cause the camera to rotate on the tripod screw axis and do a neat impression of a slowly falling railway signal I have had this happen with both 24-70 and 15-30 Pentax lenses.

The L-shape bracket prevents this from happening as the shorter side of the plate buts up against the side of the camera body. The side arm of the L bracket also has an Arca style mount, so that for portrait mode you dont need to move the ball head, simply remove the plate from the tripod head and turn it 90 degrees.

The 3 -legged thing comes in two versions, one to allow for a grip. https://3leggedthing.com/accessories

I can see times when the second battery is useful to have instant access too. But memory card slot ? Does the camera actually write to it ? Or is it just a container ?

Without grip the 3-legged one works fine. Battery access and card access is available, though not the other one (which I never use.

Never thought about getting a grip for my K1. Camera and lens is heavy enough as it is.
