does stacking these filters affect sharpness?

I'm not sure. Because I don't have chance to use it until now. But it's not a new one, I feel not good...

the stacking of filters may cause vignetting, but should not affect sharpness.

I have never tried stacking them except for with my normal UV lens, however I have been told they wouldn't affect the sharpness. I used this along with 3 speedlites to "over power" the sun when the sun was directly overhead. I didn't feel like I needed to stack them ...not sure if I helped you at all or not, sorry! But, it is well worth the money!

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 Scott, any additional filter you add to a lens will affect the sharpness, but dependent upon the number of stacks, the effect may not be detectable on the photos with the naked eye.

I would not stack more than 2 filters. There probably won't be any effect on sharpness, but you could get vignetting depending in the lens. Try it, if it works fo9r you, it's OK.

UV filter coating imbues a slight color tinge, and reduces the amount of light. Clear is actually preferable. UV filtering is unnecessary with modern lenses.

You will be able to use to auto focus with these filters, wont affect in any way.

Assuming you're asking about the polarizing filter, I have not noticed any significant darkening of the corners at 16mm (NEX-6). It may depend on the angle of the sun though. For the price I paid, these are an excellent value.

it depends on the design of the lens. It won't affect the image quality though.

Yes, this is stackable with a similar sized filter. Keep an eye out for reduction in Image Quality.

yes, you can stack them, and they should fit the Nex-7 Sonnar E 1.8 lens, however - as a 24mm wide lens, as you stack them, the edges may become visible in the frame. not sure of the crop ratio with the given lens / camera combo, but with stacking any filters - you are extending a length of tube the camera looks through. if this is an issue, a common work around is to buy a step-up adapter ring and use larger filters. (say, a 49-52mm adapter, then buy 52mm filters.) it all depends how far you need to stack.

I tried to duplicate your problem with the B+W filter. I noticed no purple problems with it on but slight fringing w/o.

It should work just fine with your lens. There is a bit of a color cast produced by the filters, depending on your editing skills, this is something somewhat easy to fix. I mostly use the graduated filters for sunset and notice a a purpleish tint in the sky that is otherwise not there. For sunsets, this is an acceptable fault for me. For ~$20 you cant go wrong, especially if you are buying these to determine if a higher end filter would be a good fit for your bag.

Generally, the instructions for the filters will mention that something like this may happen. I do not recall this happening to us with the filters we ordered. Keep in mind that not all filters are top quality. Investigate the manufacturer before the purchase.

The answer is "no." The filters I use have threads have threads on both sides. Most of them do so this shouldn't be a problem.

I have not noticed any change in the sharpness of the pictures. I am quite happy with the results I get, even when I stack them on top of each other.

Depending on the lens, it's not usually a good idea to use both filters. UV haze filters are pretty useless and are usually mostly to protect the lens, which the polarizer will do. Unless you spend a lot on a UV filter, it's actually going to degrade the quality of the image. If you stack too many filters together you start to get a vignette effect because it lengthens the barrel of the lens, and the inferior glass will degrade the quality of the image further. Use the circular polarizer to reduce glare and reflections or to stop down a fast lens to use in bright light, otherwise use the UV filter or no filter.

No think of them like filters. They help your landscape look better as in give you more depth when using fisheye and wide lens and macro gives you a microcospic view. For macro you have to get really really close to an object to take a photo.

I have no idea. I guess it would depend on the composition of the filter that you have. This is good stuff.

I would expect that you would notice a reduction in glare, if you tune the orientation of the filter sheet. Be aware that there is an overall reduction of light through the sheet, even when it is not affecting the glare.

I hope you get an answer from someone who is more familiar with the filters, I bought them for a friend. However I do use her camera at times and I only use auto focus and I have had the filters on it so I don't think it affects it. The filters are not high end but appear durable and are fun to experiment with for a very novice picture taker, I by no means consider myself a photographer.
