These days, I am in the middle of making a decision regarding the purchase of a new digital camera. Given that SLR is an option, a lot of lens numbers get thrown around. For example, there are 18-55mm, 55-250mm, 55-200mm, 18-137mm, 70-300mm, etc.
Recently, I ended up paying 1855/- for some groceries and had a good chuckle. Because I immediately related this value to the 18-55mm lens.
