Vignetting with Kit lens?

Just curious. My wife and I took a few shots over the past weekend... lens hoods on (as well as a HOYA UV filter). Both of us had images that had definite vignetting. I cropped them out and therefore have nothing to show. I'm simply asking a question here. Has anyone else experienced this with the kit lens and hood attached? Any reasons why both of us would have the exact same thing from two completely different cameras (both k10d's)? Thanks.

Yes, vignetting is well documented with this lens at the 18-20mm range. I dont think the hood makes a difference but I guess the filter would. I would ditch the filter from now on.

Well... I appreciate your taking the time to respond. I had no idea about the vignetting documentation but now that I know about it, I'll take steps to stay above the 18mm range. As for removing the filter, I'm still a bit reluctant to do that because of the conditions around here. Perhaps I'll try and little experimenting this weekend and see how things turn out.

Anyway, thank you again for your help.

Sometimes you need 18-20mm. Most imaging software programs have the capability to eliminate vignetting. Really not that big of a deal. Just my opinion, but I don't think the filter affects the amount of vignetting on the kit lens, especially if it is just a single filter. You will get vignetting without a filter too on this lens.

Filters are a constant argument in itself. One either likes them or doesn't. Uses them or not. Sometimes and not others. There is no clear, definitive answer. Do what you're comfortable with.

But, yes, the kit lens does vignette at the extreme focal range. Just the nature of the beast.

Hello, Steve

Actually, it makes a good deal of sense when you consider the complexity of a zoom and the fact that this is a very inexpensive one. And of course, you are also correct in reminding me that imaging software programs can help to eliminate this problem. In fact, I simply cropped it out but that is not going to be a satisfactory answer for all my images. Ultimately I'll have to learn these techniques and also to take care when using the wide end of the lens. Because of my reluctance to use a lens unprotected, I'll continue to use the filter. Besides, as you've pointed out, it likely has very little to do with the vignetting.
