Please forgive me if I am repeating info from earlier posts. I own Wimberley MH-100 and love it for shooting field sports where I am almost never shooting upwards and I am not usually standing up at full height. But for landscapes, focus stacking, or long exposures, the MH-100 is not the right tool. For the past several years, my preferred hiking setup is a handheld camera and lens with a good cross-body strap. But, as my lens combos get heavier, I have been searching for more stability than my aging muscles can provide. Common theme, right?
So, checkbox #1... can I stand comfortably and shoot upwards? Until last month when I bought a Gitzo GM4552L Series 4 Carbon Fiber Monopod with the intent of using it in combo with my MH-100 on birding hikes and general walkabouts. First, the Gitzo was over half-off on sale on B&H, but more importantly it is a tall monopod. I measured my old kit out and determined that I can stand at full height with the Gitzo/Wimberley combo and comfortably shoot up without crouching.
Checkbox #2... the entire combo (R5II, RF 100-500L, 2X Ext, Wimberly, Monopod) had to balance well and be rock-solid through the full extension range. I was concerned that the bottom/thinnest leg of the monopod would be unstable and force slower, less versatile deployments. No problems. In my first couple of hikes, I leave the bottom leg extended all the time and extend the top two sections based on situation: kneeling, standing, for fully extended to shoot into the treetops. The GM4552L is the perfect height for me and is rock-solid with all legs extended.
Checkbox #3 (and "my-cheat #1)... I've always been comfortable hiking with a big combo mounted on a MH-100 and a monopod. I rest the camera and lens across my shoulders behind my neck and use the partially extended tripod as security and a balancing arm in front of my body.
Checkbox #4 (and failure #1)... Birds in flight. I have no problem shooting fields sports with the combo. But BIF and close up action sports shots are better off handheld. The MH-100 really does approximate a gimbal head without the need of a full tripod, but I have never been able to achieve reasonable responsiveness with either. When "bleep" gets real and is upclose, go handheld.
For me, the game-changer is the height of the monopod in combonation with the WH-100... being able to stand comfortably at full height and aim the camera up into tree tops. Weight and stability become less of an issue when I can hike with the weight of the camera and lens across the back of my shoulders and the combo is rock-solid for action stills.
