Will a lens filter and lense cap work together?

[KmH]

My photography class instructor recommended it to protect the lens. She said she always keeps one on all her lenses and it saved her $1,000 lens when she dropped it. Cracked the filter but the lens was saved. I'm not sure if it is a good idea but she swears by them.

She does not know for sure that the cracked filter saved her $1000 lens. All she knows for sure is that the filter cracked.

And if somehow a front lens element of a $1000 lens does get broken the lens can be repaired and usually for a lot less than $1000.

The front lens element of a $1000 lens is substantially thicker and more robust than the thin glass in a filter.
In fact, at the front of a camera lens is usually several quite thick glass elements in a group that support each other. Look at the cutaway photo below.

Soft focus, lens flare, and Newton's Rings are common problems caused by a filter screwed to the front of your lens.
Use a filter when it's needed. Take the filter off when it's not needed.

In short, your photography class instructor has given you bad ans incomplete information regarding the usefulness of having a UV filter on your lens.

My apologies you are absolutely right robbins. That said with all the filters I use they are threaded in the front so at least for the canon, zeiss, and rokinon lens caps I have they all work perfectly well with the uv filter.

Edit:
I should have direct this at SCraig.

No worries. Trust me, this comes up at least a couple of times a month. If not your post it would have been someone else's. The debate will rage on regardless.

The issue isn't really debatable if everyone has the facts.

While there are some limited situations when a clear or UV filter put on a lens will offer some protection, leaving a clear/UV filter on a lens all the time is not a recommended practice.

The OP's instructor statement that a cracked UV filter saved her $1000 is at best a WAG - Wild Ass Guess.

Which has yet to stop the endless debate. So, yup, not going down that road. Will be happy to wave to you as you pass by.

Here's an idea. And a really stupid one at that.

Why not start a STICKY about the "UV filter as protection"?

Then, once the debate (definition of 'debate' as it applies to this subject: a discussion between those that are educated on the merits and those who are not) rears it's ugly head, it can be directed to the Wallowing Pit of Applied Misinformation that is the sticky.

I like this plan. I'm excited to be a part of it. Wallowing pit of misinformation on your left folks, please watch your step...

We need a "No-Religion Religious Arguments" forum: UV Filters: Yes or No, Canon vs. Nikon vs. Sony, Photographer or Equipment, Raw or JPG, etc.

OP, as it was pointed out, in most cases you'll be able to use the hood with a filter on the lens, especially Nikon kit lenses since the hood attached to the outside of the lens barrel.

And a cap if so desired.

I used to have a stack of around 10 filters threaded together and my old lens caps were also threaded. The newer snap-on lens caps were made to work as a replacement to the thread-on caps so in most cases it should be no problem to put on a filter and then place the cap on the filter.
