Filter Sizes?


I am new to SLR photography. But, I am learning. My question might sound silly, but I'm interested in purchasing some filters, and I am unsure which size to buy since the camera I purchased was used, and I do not have a manual. If for instance I am using a 50mm lens, do I just purchase a 50mm filter? And for a lens that is listed as 85-210mm, which size would you buy?Or is there a certain brand that I have to buy for it to be compatible? I know this might sound silly to some, but I am really clueless. Thanks for your help.

  I know the feeling when it comes to filters. Filters are not tied into the focal length of the lens or to the type of camera used.
I have a 28-70 lens with a 72mm filter size and a 85mm lens with a 58mm filter.
I brought tons of different filters at first. For one reason, I kept reading about this type or that type of new filter that adds "pop" to the image. For another reason, I kept buying lens without paying much attention to filter size. Both things can be an expensive challenge due to the cost of filters and the amount of room they can take up in the camera bag.
You might want to consider getting initally a "skylight" filter for each lens that you buy. Most photographers have favorite types of filters that they add but the type you need depends mostly on the types of subjects you shoot.
Canon EOS lens tend to have 52mm, 58mm or 72mm filters for the consumer brand lens. The larger the filter, as a rule of thumb, the more it costs to buy and the more room it takes in the camera bag.
One way to buy a metal "cap" system that professional store carry to safeguard the filters.
I am sure you will hear numerous and different opinions on what type of filters to buy so I will leave that issue alone.

  The size of filter you need is often stamped on the inside rim on the front of the lens. Just don't confuse your focal length with this number. If you're still not sure take your camera to a local camera store and they will help you out. They can be very helpful when they see a possible sale.
