first my concern... i just got a nice siuri p324 monopod. my lens and camera are about 8lbs and i have some concerns, it seems to screw on to the lens tripod mount nice and tight but i am not 100% sure i trust it. i would like to be able to throw the monopod over my shoulder and carry it around with out worry about it unscrewing from the mount.. i am just a little worried about the the lens screwing loose from the monopod when i have it thrown over my shoulder due to the weight of the lens and camera.. is this something i need to worry about and if it is what are the chances of the camera falling off and crashing to the ground. i do have a way to secure it but i would rather not if i do not need to. i pulled the siuiri K20X ball head off of my tripod, i can put it on the monopod, you can lock the ball head head onto the monopod with a set screw that screws into the bottom of a hole on the ball head. this seems like the most secure option but that ball head roughly adds 1 lb nothing is going to come loose this way, it seems like the most secure option.. but i would prefer not to use the ball head and ditch the extra lb. so what do you think.. just screw the monopod on to the lenses mount so its nice and tight or should i keep the ball head on the monopod to be safe. -------------------------------------------------------------------------------------------------------- what i like about the monopod with the heavy lens.... 1. i got some back issues and that 8lbs of camera and lens can be quite unpleasant. with the monopod when i am standing still i can just rest the monopod on the ground and all of the weight of the camera and lens is now supported by the monopod and not me. all i need to do at this point is hold on to it so it does not fall over, i set my camera strap to the longest it can go and i can still wear the strap, if the monopod slips out of my hand its not going any where because the strap will catch it, plus the monopod has a wrist strap as well. often for the bird photography i am just standing still for periods of time holding all that weight and that really starts to make my back muscles tighten up and ache after a couple a hour or two. so far it seems like this is going to be a huge help with the aching back.. i went out on my back yard for about 30 min with it today and it seems to be a big help over all. 2. having the monopod over my shoulder so all the weight is behind me when i am walking around seems to strain my back less. when just using the neck strap and all the weight is at the front of my body it seem to strain my back more. 3. when i see a bird up in the sky or way up in a tree and need to lift the camera up to the sky, since i am holding on to the monopod its self i can keep my elbow against my body and use my bicep to tilt the camera which actually makes it feel lighter even though there is a added lb or two from the monopod and ball head, without the monopod my shoulder was doing all the lifting, even just to bring the camera up to my face to look into the view finder can be hard on the shoulder after your out there for a while.. my biceps are much stronger than my shoulders are. unless you one of those wild life photographers that wants to crawl around on your belly and what not. the monopod seems like a huge help and it does not seem like its going to slow me down trying to shoot birds like it does when i have tried to use a regular tripod ( regular tripod sucked hard for bid photography) i was worried the extra weight of the monopod would be a issue but i also though it might help, i was not really sure, i have been thinking of getting one for well over a year now and finally decided i need to give it a try and see how it goes. as of right now i thinking it was a good purchase.. tomorrow of the weather is good ill probably be out with it for a few hours so ill know for sure.
