2 newbie questions regarding buying lens:
1. is the max aperture size related at all to the quality of lens? in another words, is it always true that if i buy a F/2.8 max aperture lens to shoot at F/8, its quality will always or most probably or mostly be better than say a F/4.5-5.6 max aperture lens also shooting at F/8?
2. is it always true that the lesser the lens groups and elements, the better the quality? how true is that?
let's say if i used a nikkor AF 70-300mm f/4-5.6G with less construction than the 18-200mm, both of which i shoot at maybe 100mm focal length. would the 70-300mm be better if the lens groups and elements is lesser?
