Originally posted by LeDave I've been looking at many pictures with telephoto zooms and primes and the thing that amazes me is the many shots that are taken with these zooms that would possibly require fast movement of the hand and even feet when using primes to get the composure right then snap away.
I used to have a DA* 50-135 and although I can hold the lens still, at 135mm it's still shakier than when I am shooting at shorter focal lengths. I'm a young guy at only 20 years old and I can hold things pretty still but yet I'm still amazed by some things.
The thing is also with primes, how can one compose so quickly with a prime telephoto, is it just shoot away at anything and then crop? Because I've seen some pictures of things that will require fast composure before it's gone and yet at the same time, with the distance and the focal length of the lens itself, sometimes I think it would be impossible to hold it that still after composing. I would probably accidently add some motion blur to the picture by moving it that fast then trying to hold it dead still for a split second shutter button press.
Even at higher F-stops such as F8 and F11, yet it's so still. Do you guys run around with these big heavy lenses and a tripod with your feet to compose, then quickly set it down to snap the picture or something? I mean jeeze, here are some examples I speak of.

Canada Rockies, grab copies of Understanding Exposure and Understanding Shutter speed by Bryan Peterson. Often one needs to up the shutter speed on, among other shots, a long tele shot to get proper exposure AND stop movement. Until reading those books, I never got it and tried to shoot everything at ISO100 since it was what I learned way back when as I was first learning photography. Shooting at ISO400 using 100 film was something that never worked well for me...but after those two books, I have no prob going to those lofty shutter speeds and higher ISO settings. The nice thing is there is always a way to get the same shot with different settings so everyone can shoot in their own comfort zone. But as I learned it works better if we learn to move outside that comfort zone.
Nothing drove it home as much as when I had my Sigma Bigmos (150-500) which needs a LOT of light. But when shooting critters you need the faster shitter speed. So a shutter speed on the long end often had to be at least 1/1250...but to get the right exposure on a SUNNY day I needed ISO800 or more. Took a long time to trust those settings. Now I don't even give it a second thought which is where I always screw up and forget something. hahaha....
