With all do respect, Mr. Professional, a tripod is recommended for any shutter speed slower than 1 / twice or three times the focal length. Assuming he has a 1.6x cropped body, that means his shutter speed would have to be no less than 1/640 but preferably 1/960 or faster.
Go ahead and have your 'chuckles', but in the end, you'll be the only "professional" chuckling. There is absolutely no reason not to use a tripod or monopod. All the professional photographers I have shot with (yeah, you're not the only pro on here
have shot with a tripod in broad daylight. You're not going to miss the shot because you have a monopod. A tripod, maybe if you aren't quick with it, but that is going to be your fault for not being prepared before hand.
Not to mention that with his body and a majority of the other bodies on the market, turning up the ISO just isn't a solution to low light situations. It'll generate simply too much noise to be useful.
I'm sure hand holding your camera at those sorts of shutter speeds will give you good enough shots that you're mom and girlfriend will say to you "wow, amazing photographs", but as soon as you take them to your editor or whatever sort of boss you have, it'll be shot down.
If you want to use a monopod, by all means do so, I was just trying to give you some insight. No offense intended my friend.
To clarify, a monopod only does you any good if you know how to use it for the situation. When you are tracking with a moving subject, unless you are moving your feet around the monopod, you are rotating your body and keeping your feet planted. That causes the monopod to angle slightly, causing your frame to be crooked unless you adjust as you pan. If the monopod is attached to the camera, that adjustment is impossible. If the monopod is attached to a lens with a rotating collar, you can make the adjustment with practice. As for shooting a fast paced game like lacrosse with a tripod, good luck with that. Tripod too have their place, but in 20 years of covering NCAA sports, I have never seen a tripod on a field/court.
Please leave my mom and girlfriend out of this.
I have photographs published every day. I'm not making this up for my own amusement. I am trying to give you guys the benefit of my experience, but if you don't want it, that's cool too.
FYI....I would never laugh at your monopod.
What I was saying was that amateurs see us with our big lenses on monopods, and think that a monopod with significantly help them, when most times, it won't. For low light, there are a few tricks with a strobe you can use to get shots if the lens is too slow.
