I'm going to Kruger National Park in South Africa, how be should my zoom lens be for it? I have a 300mm one. Do I need a 500mm? I have no idea how close they get to animals...... Also the bigger the lens, does shaking affect it more/ Do people use a tripod with the 500mm and 300mm
Answer
The problem of shaking as you know is amplified by several factors. The first as you mentioned is longer telephoto lenses. The next factor would be the size of aperture, the smaller your apertures the slower your shutter speeds will be i.e., smaller apertures = less light and longer exposures. The last thing that can amplify your shaking is what ISO film or setting you choose. The lower your ISO the longer your exposures will be simply due to the fact that lower ISO films don't react as quickly to light. Of course in many cases it is more ideal to use a lower ISO film because of the grain, and lack there of, however with some action photography this just might not be appropriate and you may have to go with a higher ISO film or setting especially when lighting conditions are poor and the use of a flash is just not effective because your subject is too far away.
So as you learned from the previous post fixed focal length 500mm lenses are not cheap and can run several thousands of dollars. Of course you can go for off-brand fixed focals or zoom lenses but quality is always a concern and especially with these long focal lengths you may run into things like chromatic abberation. However I have to say that with most of your major non-mfg lenses this isn't the case.
I am not sure if you are on a budget or not but if you are then my solution is this, buy yourself a 2x converter for your lens which would make your 300mm lens a 600mm lens. Check with the manufacturer of your lens to make sure this is possible. The only drawback of course is that these 2x converters will affectively reduce your minimum aperture, usually by 1 stop or so, so that if your minimum aperture is 5.6 then it will be 8. This of course can be offset by using a higher ISO setting. I would suggest that you take a look at keh.com if you are considering purchasing a lens or lens converter. Furthermore if you are worried about stability and shake, then purchase yourself a monopod as tripods are too much of a pain in the field when you are photographing nature and have to move a lot.

hello i want to get the canon rebel t2i and i was wondering if http://www.google.com/products/catalog?client=safari&rls=en&q=canon+t2i+wide+angle+lens&oe=UTF-8&um=1&ie=UTF-8&tbm=shop&cid=8153805409731932107&sa=X&ei=U9qWTrjBEKH10gH7y_TBBA&ved=0CGsQ8wIwAQ#ps-sellers fits the canon rebel t2i ? and is it good ? i can't get a fisheye or wide angle lens and soon as i buy it ..but it will take time for me to get a good 200$ one so I'm going to need one ...and i know nothing about lens sizing etc and filters if you can leave me some information about lens sizing and stuff please ..1 thing i know is that cheaper lens will lower the quality but i don't really care as long as its good and hd i don't need top resolution
i will be using this for skateboarding so yes it is in a specific field
Answer
The T2i is a good camera and usually comes with the wide angle lens, the fisheye lens is something that will not be used very often unless your in a very specialized field.
As long as the lens has the same common mount you can use it on your camera I would suggest you just buy lenses that fit, the adapters don't work well they throw off your F stop settings.
If your looking to save money look into Sigma lenses they are less expensive and just as good and will fit your camera.
A wide angle lens and a zoom lens would be a good start and when you get more into photography a macro lens but the fisheye lens will probably be a waste of money and they are more expensive then the others and won't be used much.
