There are a few non-essential items that could help you get more from your photography. These could include: a remote control (or other system for using the ‘Bulb’ feature of your camera), a Neutral Density filter to fit your ‘normal’ (35-105mm) lens (this is particularly helpful if you’re interested in special effects or video), a polarizing filter (also usually best for the ‘normal’ range lens), a ‘step up ring’ (useful for fitting one expensive filter to several lenses of varying thread diameter), a small towel to pat your equipment dry, lens cloth or LensPen, spare battery and charger. We strongly recommend a waterproof bag or case to store and carry your equipment in.
