filters basics ( EOS-300D )

[psychonaut]

will any 58mm filter fit ?

another quesiton: to what extent can software do away with the need for filters ?

optional: how many filters do you own ?

???

thanx

1.The size of the filter will depend on the size of the front element of each lens.

2.Software removes the need for great deal of filters. Exceptions being a polarising filter.

3. A good UV filter on each lens for protection. 2 CPL filters. ND and ND Grads.

If you're talking about the standard lens that comes with the EOS300d (EF-S 18-55mm) then yes this does come with the 58mm thread, so you're pretty safe.

As Lomond says, a good UV or Skylight filter will protect the lens...it's a lot cheaper to replace a bit of glass on the front than the bit of glass in the lens!

A circular polariser is a must.

You might want to play with the filter effects in PS and the like, some poeple prefer to use them at the time of taking the photo, some in the edit.

I use some of my old Cokin filters, these are pretty good for things like grad NDs, less hassle to use than screw-in grads.

UV/Sky for all lenses (except the 15-30). At least one circular polarizer in every size (52, 55, 58, 77), again except for the 15-30 (it takes in half the sky - a polarizer on that would be insane, never mind the cost of a good 82 mm CP). Singh Ray ND grads and a Cokin P with adapters for all lens diameters (52, 55, 58, 77, and 82).

Part of what Jon stated is that circular polarizers work pretty good for middle focal lengths and normal landscape scenes. As you start going toward the ultra-wide focal lengths, you are taking in a huge expanse of sky. Polarizers will still work there, but you get an odd effect. Half of the view of the sky will be in the "right" direction, so the polarizing effect will be pronounced. The other half of the view of the sky will be considerably away from that direction, so the polarizing effect will be nil. The result of that is that half of the sky looks dark and half looks light.

So, I never use polarizers wider than about 20mm (on a 1.6 body).

Thanks for elaborating, Bob. That's exactly what I was referring to.

hm... how can UV damage the lens, and why dont they put in uv protection standard ?

can u have two filters on at the same time ? like a UV and Polarizer ?

thanx :-P

UV light does not damage a lens, nor does it damage a modern digital camera. However, flying sand, flying rocks, and low-hanging tree branches will damage the lens.

Many photographers want to put something out there to protect the lens, and a simple UV filter is about the most transparent and cheap one there is.

You can beat the low-hanging branch problem with a lens hood, but that doesn't help much for any windblown crud that could hit the lens.

A friend of mine hurriedly threw an expensive Nikon lens into his case after a wedding shoot. The front of the lens was rubbing against something in the case. For the next wedding, he opened up the case and found this big scratch across the front element. If he had used any simple filter, he would not have had to replace a $1000 lens.

Of course, if it had been a Canon lens, then it would have broken my heart.

i went on B&H and ordered Tiffen CPL and ND Grad, Canon UV filter and Tiffen 4-filter pouch LOL.

should be enough to stay entertained for a while :)

thanx everybody.
