In the first post of this series I argued that you can save lots of money buying manual focus lenses and get great pictures with your DSLR camera. In this post we’ll look at three more lenses: the Mogens’ 500mm f/8 FD mount lens and his Helios 58mm f/2 M42 mount lens.
First one out is the 500mm. Since it’s a M42 lens, the adapter steals 1/3 stop of light and gives a 1.26x crop, making this equivalent to a 630mm on a APS-C sensor or a 1008mm on 35mm film/full frame sensor.
Be sure to follow the thread, more exciting manual focus lenses are comming up. To wet your apetite, we’ve ordered in a bunch of Pentax K lenses and adapters to other lenses that are laying around.
