Will these filters cause problems with auto-focusing?

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.

They have yet to pose a problem for me. Caveat: I am a casual photographer so they may be a problem for someone more expert.

I have used the clear filter and the polaroid filter. Neither had any effect on auto focus. I am pleased with the filter kit.

Yes, don't listen to these yahoo's who tell you not too. You are protecting your investment. Better to crack a filter than the actual lens, especially a more expensive one. And to the person who said it affects lens flaring... that's what a lens hood is for.I slap a $10 Vivitar on every lens I get. From my nifty-fifty Minolta to my Zeiss and G lenses. There is practically no difference in image quality and if anything it might be better. I am a professional photographer who shoots weddings, portraits, landscapes, etc and never take my equipment without protection.

Yes, they are, but you have to get closer to an object first, so camera may use autofocus.

Yes, those fit very well, but only the filters works well, the lenses quality are poor. I will not recommend it

Yes. I have been able to stack all the filters all at once and use it to get very close to my subject. But at that range, the shadow of the camera obscures the subject. In addition tothat, chromatic abberation (purple fringing) gets worse as more close up filters are added. the +10 alone exhibits a lot of purple fringing. I hope this helps.

I have never had that problem. My lens adaptor screws on and off as easily as any of the filters I use. The only guess I can make is that the threads with your adapter were defective in manufacture.

You should have no problems. Align the white dot on the small switch with the tiny red bar near the aperture ring and it will be fully automatic (focusing and aperture). I use mine on a D80 and D7000. Works beautifully on both.

AutoFocus was fine. Some circumstances, e.g., bird watching, require manual focus.

No- make sure the filter is in correctly. That caused problems with mine too!

I have no problems with the auto focus with this band on. I have used it several times

Usually yes. If you're in an auto mode there me be a delay for focus / light metering etc like most dslrs. However none of that in manual.

Hello Brian, in the years I have used this lens all the time and I can report to you that I have never had any problems with this excellent lens. It is sharp and the contrast and color are beautiful. Focusing has always been crystal clear. Also focus speed would be a function of the camera body which has the drive engine for autofocusing. Hope this helps, Paul

With this filter the camera does not auto focus or do the auto exposure correctly because this filter lets in so little light for the auto focus/exposure to work. The way I use it is to first get a exposure reading without putting on the filter. Then set an exposure using the manual setting (M) that is 8 to 9 stops higher to account for the filter (I decrease the shutter speed by 8 to 9 stops). I also at this point switch to manual focus (or auto focus without the filter and then set it to manual focus on the lens). Now I put on the filter and take the picture. Even though the filter is rated as 9 stops you may need to bracket manually between 8 to 9 stops to get the right exposure.

Those filters fit very well... but you must pay attention to de measures of your lenses...

I use sigma filters on all of my lenses and have had no problems with smudging when cleaning. I use a nikon cleaning pen generally when I clean and all of my filters stay spotless.

Dinosaw,I've used these star filters in astrophotography to highlight bright stars. They don'tadd any distortions at all. Zero chromatic aberration, no vignetting as long as theyare stacked with other filters, and no detectable edge distortions. If you want tocreate highlight effects on bright objects, I highly recommend these filters.Best wishes, Ron Smith

Yes. With 'auto focus' they would be great, but should be supervised as they can break if dropped hard enough.
