Super Woman
This woman photographer is amazing! She must be from the planet Krypton.
She’s an older person (I would guess in her late 50s, early 60s) and she carries a 1DMk4 with a 600mm f/4. She makes her photos HAND-HELD. That’s 24Lbs/11Kg at the end of her extended arm.
That day, the light was not the greatest, it was grey, low contrast and very cloudy. Either she’s super-woman or she uses ISO 100,000. Look at the arch of her back…
Just holding such a big and heavy rig at the end of the arm is hard enough for me. That’s why I mostly use either a tripod or at least my monopod. And my monopod is usually set to be 2½ feet tall. I wear a single carpenter knee pad on my right knee and I kneel down, just like Tim Tebow but I was doing it long before he started to play football. I kneel to be closer to the ground and have a different perspective than 98% of the other photographers.
BTW, she’s just holding the lens up, at arm length, without even taking photos.
