Different cameras can produce very different images. One of the funkiest lenses available today is the 60mm f.8 lens of the Holga. The lens is soft, the shutter vignettes, and the single shutter speed of 1/100 of a second is suitable to introduce just a touch of motion blur on top of the aberrations inherent in the single meniscus design. It is a marvellous piece of plastic.
The Carl Zeiss 50/1.7 Planar lens of the Contax is at the other end of the scale in terms of design complexity. It is a fast lens made up of seven elements of glass. It is sharp, subtle, and smooth, and the lens alone costs more than ten times the price of the Holga camera. That doesn't make it better, of course, just different. OK, make that very different.
