Will 77mm ultra thin filters work on f/4 300mm L

[henry_ed_fly]

Will the 77mm ultra thin filters (UV & circular polorizer)work on a Canon EOS f/4 300mm L lens? These filters were expensive and I no longer have the wide angle lens that they were purchased to use on. Thanks.

No problem. You can use ultra thin filters to any lens. I also use

ultra thin filters to telephoto lenses.

Why wouldn't they work?

The whole point of thin filters is to minimize the risk of vignetting

caused by the edge of the filter frame darkening the corners of

the image; a problem most common with wide-angle lenses.

There's no problem using a thin filter where one is not needed -

the only thing is you'll have to deal with the drawbacks of thin

filters. (ie: since they usually lack front threads you can't always

attach regular lens caps when the thin filter is in place)

if you have both the 77mm ultra thin filters and EF 300mm f/4 lens,

try it out. unless and until there is any electrical contact, any 77mm

filter should work with any lens having that filter size. you just

have to be careful about vigneting. if you don't see any vigneting

through the viewfinder, then i guess that you won't have any problem.

Electrical contact? What on Earth are you talking about?

I think it's sarcasm, NK Guy.

[sajeev_chacko]

Guy, i exactly meant electrical contacts like the one one any

teleconverters. since <b>NO</b> filter, manufactured so far, has any

such contacts, there should be <b>NO</b> problems for using any

filters on any lens (of the same size, ofcourse).

[john_peter]

Filter with an electrical contact???? That is interesting. Why would

one make a filter with electrical contact? I dont think so. BTW..

Sajeev, do you know what we are talking about? Filter never require

any kind of electrical power to work. It is some thing that is

screwed on to the lens or slide into a filter holder.

You can use it, Even I am using an ultra thin filter on my telephoto

lens with out any problems.
