I'm not the expert, but this is my experience:
1) The cheap wide angle lenses don't have fish-eye, but do distort,
esp on the sides. You'll find straight lines, like buildings, lean in
toward the center; a wide horizon curves (unless it's across dead
center of frame, which is poor technique). At least on some; more on
some than others. Not full fish-eye, but some distortion. One of the
primary differences between a $30 lens and a $300 lens.
2) Often these cheaper lenses have vignette effect. That is you will
see part of the lens barrel clip off the corners. You can eliminate
this by zooming in, but then, why get a wide angle if you have to zoom
in and wind up with the equivalent of what you had before installing
the lens? More expensive lenses, exp those by the same camera
manufacturer, are made for your camera and won't have this effect.
Depends a lot on what the widest angle of your camera's native lens
is. If very wide, then more vignette with a cheap WA lens. If not
really wide, then this is not an issue. I have a couple of these
cheaper lenses gathering dust that I won't use because of this issue.
3) Cheaper lenses have less or minimal coatings. This creates more
lens flare and can alter true colors.
4) Cheap glass is USUALLY cheap glass. While not always do you get
what you pay for, in this case, most cheaper wide angle lenses will
have issues you don't want.
5) If you use one of these WA lenses, I would remove the UV and use
just one piece of add-on glass. The more add-on glass, the more
distortion. Moving the WA lens out a 1/4" by putting it on top of the
UV filter will increase vignette effect.
6) A polarizer has it's own uses. I have one, but seldom use it. Go
into a camera store and ask to try one outside in the sunlight. I
find the variable polarizer is best. Decide what type of shots you
are most likely to take, then get equipment for that. While it sounds
like you want to be ready for everything, you can't. You are more
limited by the quality of the camera itself. Are you taking family
and vacation? Surely you aren't trying to get paying gigs using this
camera? The story you tell and how you craft - that's CRAFT, the
final production, even for family and vacation stuff, will make more
difference than a WA lens, or polarizer, etc. As you shoot look for
"B roll" stuff, like signs, close-ups of feet running or walking; get
down for low angle, up for high. Fill the frame with faces from ear
to ear. Think about how you will tell this story as you shoot. Can
you create drama or mystery? What's just a family birthday video can
be made special by cutting in old photos of the person as they grew
up, and asking the question of what does the future hold for them? Do
you have a good video editing program and a fast computer? These
things are much more important than the questions you have asked.
7) Neutral density is up to you. One use is to open the lens
aperature and get less depth of field. Tough with your camera. The
very small sensor will limit you more than aperature. More than
likely, your camera with its 1/6" sensor will have everything in the
picture in focus at all times. By getting back and then zooming in,
and opening the aperature, you might get some depth of field with the
classic cinema "fuzzy background" most serious videographers want.
Usually too much trouble for the amateur taking family or vacation
video. If you want everything in focus, and some do, esp for family
stuff, then why consider neutral density?
8) Panasonic is a good brand, but has a wide range of models and
quality. This is more of an entry level camera with OK images. Great
for family and vacation, not for serious documentary or Indie films.
A wider angle is good for inside rooms, and for scenery, but remember,
50% or more of your shots should be close-up. Even for family video,
you will be noted as being very good if you tell a story with a
beginning, a middle, and an end; use lots of close-ups which draw your
audience emotionally into your production; and KEEP THE CAMERA
STEADY!! I'd get a tripod before a WA lens or other. I like one that
has a monopod built in. I used to shoot all handheld, then started
using tripods, and while I thought I was good before (steady with
elbows on something, holding my breath, etc), the difference is well
worth the hassle. Unless you want a specific effect that emphasizes
handheld (which is becoming more popular in TV), the steady shot is
the sign of the pro. But story trumps all!!
9) Remember that shooting is the fastest and easiest part of video
production. Most of the time is spent editing. Don't think you have
to make the final production with scenes in the same order as shot.
That's why it called NLE. Non Linear Editing. Craft a complete
story. Put in titles and credits. Use music and narration, but
please, never use copyrighted commercial music if you upload to
youtube or other places, or give a copy to others. For a single copy
for use of you and your family when you have purchased the music ...
well, that's up to you. Find a way to get really good sound - the
soundtrack is 70% of what we call video! I don't think your camera
has a mic in jack, and the onboard mic will sound tinny. Consider
buying a separate audio recorder, and get software and a good computer
that will allow you to synch the separate audio with the video, then
delete the onboard soundtrack for what should be the better quality
separate audio.
10) For a while, just shoot and enjoy. Forget the accessories and
paying $$; they won't make enough difference to make a difference.
Instead of wide angle lens, just pan a little bit. Polarizer and
neutral density won't make much difference with the limitations of
this camera. Buy and extra battery instead; and a tripod; and decent
editing software; and blank DVDs. Spend time editing and crafting
good stories your family will enjoy. Beginning, middle, end; craft a
story; close-up; tripod; good sound; editing equipment and skills.
Don't just shoot and show! Create productions. You'll find it's
either in your blood and will spend the hours, or you'll just shoot
and show mediocre stuff they'll watch once, and the camera will be
used less and less. It's in my blood, but then, that's me.
More than anything... Have Fun!!
