I just bought a Canon T4i with 18-135 stm lens and 55-250 lens. I have never used an advanced camera like this before. I am going on a safari, so hopefully it will be useful. Anyone have experience with that camera and those two lenses? Is it good for a beginner?
yes very good...make sure to read up on exposure settings (aperture, shutter and white balance), learn how to set the various metering modes (spot, center weighted, etc) and play around with focusing subjects before you go on your safari.
for daylights, to shoot animals...i'd set the center point on focus, keep metering on center weighted average and keep the camera on aperture priority if subject is slow, non moving. if animals are moving, move to shutter priority and set a shutter speed of 400 or above.
you might want to rent one of the various 70-200mm canon lenses, as you need a better telephoto lens to capture wildlife than the one you are getting. dont get me wrong, you will be able to take pictures just fine with the kit telephoto...but they may not hold up on print.
