Hi! Question about filters :)

Hi everyone! I'm not sure this is the exact right place to put this, but I'm brand new to this forum so just correct me if I got it wrong I currently shoot with a Canon EOS Rebel T1i. I have had this camera for about 2 years and it's done well for me, but very soon I will be upgrading to a Canon 5D Mark ii (squee!!) I have done extensive research on this camera and I know it's the one I want. What I'm not sure about are filters. Which ones are recommended, and mostly what size? I believe for my Rebel I use 53 or 58mm filters. But I'm just not sure what size to get for the Mark :/ Thanks everyone!

The filters go on the lens, the lens cap usually shows the filter thread size needed for that lens. Changing the camera won't matter unless you're using different lenses.

As ^^^ mentioned, filter sizes are dependent on the lens, the body doesnt matter.

In order of usefulness -

• CP - Can be used to enhance an image in a way that's totally impossible with software.
  
• GND - Has an effect that can be replicated in software, but never with equally good results.
  
• ND - Specialised uses where a very slow shutter speed is required in bright scenes.
  
• Special Effect Filters - things like Star filters - Can often be replicated in software (if you should ever be sad enough to want to).
  
• Coloured filters - Can normally be replicated easily in software.
  
• UV/so-called 'Protective' Filters - Can easily be replicated by using the 'Blur' and 'Lens Flare' tools in Photoshop.
