New and old 135mm lenses compared.
Between these two images, I would say that the $1130 price difference between the two seems a bit much. But keeping in perspective. One is a modern auto focusing lens, while the other is all manual. But it does go to show that if you look hard enough you can find a great lens for a bargin.
The 135mm focal length isn't a length that is all unforgiving however it is somewhat important that you have decent eyes to focus properly.
