10 of the best SLR video accessories
Lens adapter for classic prime lenses
amazon.co.uk, around £15
Autofocus zoom lenses made by the likes of Canon and Nikon can be really pricey. If video's your game, play it smart and get an adapter so you can use some great older lenses like the Olympus OM mount Zuiko range. You'll want to use manual focus anyway, and prime (fixed focal length) lenses can be picked up for under £100 on ebay.
