do these lens make a picture more sharper and clearer?

Absolutely! Plus, I primarily use these during Skype calls and receive very positive feedback from the other end on that as well.

Yes, especially in bright light. It somewhat depends as well on how steady the photographer is, of course. The HD movies are also really crisp, and I've used stills from these as very nice photos.

No. There is a slight magnification that helps with making text / images clear. Sort-of like reading glasses, but not quite as extreme. I have 20/20 vision, and can use them just fine.

Well, there are subtle shadows with any of these lenses. This doesn't bother me though. The lenses are really fun, especially the fish eye.

No. While they will sort of work these are not active lens. They are basic polarized 3d frames. Good for the movie theater. It is like watching 480p on a 1080i screen. It can be done but you miss out.

Yes. The "pros" will tell you that any additional layer of glass can add distortion and reflection, but I leave a filter on all the time to protect that expensive lens from dirt, dings, fingerprints, etc. Many of today's filters are so well made with multi-coating and high tolerances that I doubt even the experts can tell a difference in 99% of photos. Years ago, so called UV filters added a hint of pink to fight UV. That is no longer the case.

Not from what I have seen. At 100x, the distortion is beyond a focus adjustment.

No I did not notice blurriness around the left and right sides. For the price the lens did ok.

No, this will not improve your existing camera lens. It will allow your camera to take Wide Angle, Fisheye and Closeup photos with whatever resolution your camera is capable of... It is cheap and fun.

Yes. Just like most macro lens extentions there is a fish eye effect. Zooming in will bring it down some but the lens is curved to create the effect so it will take digital altering in the end for a non-warped image.

Yes they have stronger lens than those you posted above. You can also get a "shorty Barlow" lens that will double your seeing power

Yes. The lens is faster so you should be able to take clearer shots in darker situations. If you need to compose pictures holding the camera above your head or down low, however, the lack of the tilt screen will make it much more difficult.

if you are talking about micro four thirds cameras then yes, but its not a razor-sharp lens. The Panasonic 35-100 mm f/2.8 is much sharper.

The lenses in these are not as sophisticated as the ones you would get from an optometrist. Consider the price! As a rule, I normally go down rather than up, so in your case I would get -3 (rather than -3.5)

Hi, I didn't really like this lens. It doesn't have the effect that I was hoping for. The lens cause an effect on the photo that I did not like, on both sides and its not a very good wide angle, if you are looking for an effect more like a fish eye as I did.

I didn't experience any lose of sharpness. However I stack This filter with a CPL Filter. And also I didn't experience any problems. Basically I shoot Landscapes with small apertures, so usually the depth of field is wide and everything seems sharp and in focus.

Yes. They work really well. I have taken several shots with them and they are working great. Here is a website of some of my pictures. The ones with the fall colors are the ones where I used both lenses. You can check it out and let me know if you have any more questions. The people are really good to work with. http://yourshot.nationalgeographic.com/profile/151439/ Thanks Ken
