Class 10 cards should be used if you are shooting video. Besure to check the Sandisk site for current rebates.Giottos Medium Rocket Blower: Always have it handy for getting dust off lenses in a hurry,because blowing on them – no matter how careful – leads to spittle on the lenses. Also use formanually cleaning the sensor as described above.Lens Pen Cleaning System: Works great for cleaning off mysterious spots and smudges thatappear on the lens (this is why I always use UV filters) as well as that a-fore-mentioned spittle.Blow dust off the lens first with the Rocket Blower, brush it with the Lens Pen brush, and thenfollow the instructions for using the Lens Pen.UV Filters: Clear, protective filters for the lenses.

It works best when the sun is to your left or right, but does nothave any polarizing effect if the sun is directly in front or behind you. Do not use an older linearpolarizing filter with a digital camera, as it will interfere with the metering and autofocussystems.Lens Hoods: Use a lens hood on your lens to both prevent flare and to protect the front of thelens when it inevitable bangs against something or drops. Some nicer lenses typically come witha lens hood. With other lenses, buy the corresponding optional hood.BlackRapid R-Strap: A different, more comfortable way to carry your camera, especially onewith a larger or heavier lens. The RS-7 version has a nice curved shoulder strap, the RS-4 is not
