Probably not.New lens has arrived, its a hefty old lump. Do I start using a gym or buy a mono pods or whatever they are called !
Get a black rapid strap you will find that far more useful than a tripod / monopod with that lens
Probably not.
My experience based on talking to hundreds of our customers is that *most* people can cope comfortably with lenses that are up to about 200mm long. weigh up to about 1.5kg, and have focal lengths up to about 400mm. That includes the 70-200mm f/2.8 and also things like 300mm f/4, 100-400mm, 80-400mm. It's when lenses start to get heavier and/or longr and/or longer focal length that *most* people start to struggle. The physical length of the lens is a factor because if you can tuck your left elbow into your ribs that makes the camera much more stable, but that's harder to do with longer lenses. The focal length is also a factor because longer focal lengths magnify any instability.
No none at all and mono pods are very good but I am sure he will find it more a hinderance than useful most of the time (yes sometimes will be useful but I feel will be more a hiderance most of the time with his lens)You've only got one back and its got to last you the rest of your life. No shame in using a monopod.
I used to be anti monopod but after twisting whilst climbing over tyre barriers at Anglesey track years ago leaving me in a lot of pain (and then having to pitch a tent and then sleep in it) I decided that anything that can help preserve your back is worthwhile. I shoot sports mostly and wouldn't be without it, even for modest lenses.
Happy to oblige (Sigma 120-300 Sport )
