Vignettes what is that with a lens and filters?

Vignettes:
are mentioned with a lens I was looking at. I wanted a more universal lens for my new Sony SLT33. A Sony - 16-105mm f/3.5-5.6 zoom lens perhaps?
It came with two kit lenses; 18-55 and 55-200 ? really do not recall the size.
I should have likely bought the SLT55 with the one lenes but it felt so heavy.

Also, lens covers, I am gettig marbleizing affect on white walls low light. It will not focus, or shoot if out of focus. If I step back and take the photo all the rainbowing swirls come through on the white walls.
I was photographing walls with cracks where a tree fell on the roof and cracked the walls. There was a sliding door, a walk out door, and few windows. Dark inside no elec. Is this a UV or polarizing problem?

Do I need a special filter over the lens? What kind of filters do you think I should have?

Not really an answer to your question but I am looking at the A33 or A55 and was wondering if you would recommend these cameras. I am replacing my sony A300 that I loved!

Camera is perfect, especially the light weight. I just need to learn how to use it and the lenses. The photo's are for the great part fantastic, some of my work environments need settings which I know nothing about.

My son bought a Canon EOS and it is easily twice this size and weight.

For our cruise I took my point and shoot, if I knew how to use the settings for the DSLR I would have taken it.

I would like one lens that I can use for our trip to Disney.

I am not sure I am following your question exactly, but here goes. Vignetting is when there is a darkening in the corners of the image. It is caused by something interfering with how much light reaches that part of the sensor. If it is always happening on the lens alone, I would probably avoid that lens. If it is just whan that lens uses a filter, that would not bother me too much because vignetting typically only happens at the widest angle of the lens and I do not do too much with filters anyway. If you always do post processing, then the darkening is easy to correct. The real problem is that the darker part of the image is also not going to be as sharp, even after being lightened in post processing.

Vignetting with wide angle lenses that you use filters on is pretty common at the wide end (16mm). You would not find that happening at the longer end unless you had the filters stacked. I have heard a lot of good things about the 16-105mm lens and not anything about any excessive vignetting beyond what you might expect with a filter. I don't use filters on any of my lenses although I do have both ND and polarizing filters. I'm just too lazy to carry them around and I use the lens hood for protection rather than a filter.

For another all purpose lens you might consider the Tamron 18-270 or Sony 18-250. They will cover the length of your other two lenses combined and they have good IQ for ultra zooms. Quite comparable to the 16-105mm without giving up much on the wide end and gaining more zoom.

Regarding the rainbow swirling it might be helpful to see a picture showing the issue. Could you have had an odd light angle hitting across your filter causing the colors?

I would also like to see an example of the "marbelizing" you're talking about.

Do you have any kind of filter on the lens when this happens? Do you have and use a hood on the lens?
