Choosing filter BW clear nano MRC or UV UV nano MRC for 70-200

i don't know what difference between 2 filters so i need your help to choose.
main function is protector, which one is better? what is difference?
tks all

A clear filter is just that - a clear filter used for protection or completing a weather seal. A UV filter blocks some types of UV light - other than that, functionally the same.

What do you plan to be photographing where you need a filter for protection?

i shot my kids, portrait, streetlife, landscape
it seems almost people use UV filter, right? i don't know why?

if you must then CLEAR...
no really need for UV with a DSLR, neither having a light color tint add to your pictures

both are same price, which one do you choose?

None of them ! for protection i use the best protection ever provided by lenses manufacturer when you buy a lens >>> the hood !

And no need UV filter, there is already an UV filter on your sensor, we are not any more at the film era where in some condition/film you need an UV filter

Just what do you think is going to damage your lens?
Just how much protection do you think a thin sheet of glass will provide?

So we have the same lens (i suppose it's the 70-200 f/2.8 IS II)
The only reason of a filter is to finish to seal the weather sealed of the lens, but because you're already "afraid" i'm sure you will never take a picture under an heavy rain storm or a wave coming toward you

The main thing that can scratch the front element is another piece of glass or something more hard like a diamond (metal are softer than the glass)
The hood of the 70-200 is really "long" unless you are taking a picture of an arrow coming toward you, nothing will get in, at the opposite, if your lens fall on the ground the filter might break and it will be the broken pieces of glass from the filter which will scratch the front element

Exactly this thin piece of glass is just an illusion

I have the same lens. Yes the lens is over $2000 but the front lens element is probably only about $200. It seems crazy to me to use a $100 very fragile, thin piece of glass to protect a $200 very robust, thick piece of glass.

I have never scratched a front element in over 30 years of shooting with Canon SLR's and DSLR's, but if I did, I would just get the $200 front element replaced.

I have a $10,000. lens and you cannot buy a filter for it. Use the hood.

If you don't have one already you may want to consider buying a CPL. It's not a protector in the sense you were considering but it can go a long way to improving your images and creating more dramatic compositions. They are wonderful for landscape work under the right conditions.
