You can have considerable amounts of 'crap' inside a lens and still get acceptable results. Take a few frames under differing light conditions, ie also take a few into the light/sun and not just behind you. Use both the maximum and smallest aperture and both ends of the zoom range. A brick wall approx 4/5 foot high makes a good test 'card', by taking from both sides you can alter the position of the sun with reference to the lens.If the results look OK, just use the lens as it is. It is relatively simple to make the required tools if you are mechanically minded. However if you have to purchase same, as stated above, they can be a bit expensive. Also zoom lenses are not the best candidate for a 'first attempt' at a stripdown. As you are new to photography, I guess the money would be better spent on film or useful kit. |
