How long should I do this "look, its just a monopod" exercise? Couple of weeks to be on the safe side?
Long enough to learn how to move it with yourself, without hitting other folks.
Long enough to learn how to quickly employ its full length, relative to your body, without dropping kit or having to search each time for a place or spaces to put up other items, ie, the point and shoot you've just switched out for the larger camera.
Long enough how to travel with it and have a routine that includes, shooting with your bag(s), meter, filters, lens shade, secured so, others will not have the opportunity to walk away with any part of your gear, in a fraction of a second.
Long enough to both learn how to change Hasselblad backs and, to hold it secure while loading and unloading a magazine back, lens or change a filter, of each type you carry.
Long enough to learn how to quickly adjust it's length to,
1) A one knee down shooting position,
2) Amid-level (belly button position of your target)
3) A relative position of a full length extension for your height, both with the waist level at a 90⁰ viewing position and a stable lockdown view through the WLF
4) a long overhead, "Hail Mary" CROWD shot with a longer plunger type cable
5) disassembly of small and large (MF) camera kit from pod, while keeping positive control of every other kit item
6) Long enough to learn how to lean the monopod forward w/camera and neck strap around neck or shoulders, which helps eliminate wandering lenses and stabilize the camera in place for shooting, from both a free standing position and with your back against a static wall, truck side, butt only against a car, etc, so there's little movement in the camera/lenses.
A number of these exercises can be done together, the point is to practice this "manual of arms" with monopod and cameras, in real-world conditions.
For some, practice is not needed, and smooth handling natural talent does happen, but with occasionally used kit, many people need to learn by doing what is needed to get the maximum benefits of a sharpened of image and the use of it in the many situations that can arise.
Cheers,
