Anti -Aliasing Filter ??
May 27, 2020 10:51:35 #
Hello . I use Nikon D5300 cameras which do not have anti-aliasing filter in front of sensor . Curious : Just what are the pros & the cons of having or not having this filter in a camera ???

Con - reduces sharpness
Pro - gets rid of a funky pattern you get from frequency of repeating patterns.

Interesting. I have a D5300, and I didn't realize it was filterless.

Thanx for quick reply . I always thought that my D5300's were ever so slightly less sharp then D5200's I had prior . Now I know why . Think newest in D5xxx series (the D5600) did away with filter .

Not needed. My D750 has one. wish it didn't. My eyes are bad so I really don't notice the difference.

The D5300 does not have an anti-aliasing, which potentially makes it sharper than a camera with the filter

Manufactures put these on, or do not put these on according to the specific specs. of the camera.
For instance, the Nikon D850 and D500 do not have these filters, but the D5 (top of the line) does.
I have camera's with, and without AA filters. I see little difference. And I also doubt you will.
I believe camera manufactures are the best ones to decide which camera needs one and which ones do not.

Years ago, the Nikon D800 had the filter, and the D800E did not have the filter.
What a decision.
What a decision.

It also degrades the image somewhat.

Quite the opposite. Images are sharper WITHOUT the filter, which degrades the image slightly.

The AA filter causes a slight blurring of the image. Filters today are thin so that blur many times seems insignificant and readily taken care of when sharpening. Modern editing softwares like those made by Topaz like Adjust AI use artificial intelligence to analyze the image and come up with a great sharpness and clarity.
I have never used a camera without the filter but I am very happy with my results and by the way, the RAW data seems very sharp without adding sharpness. It could be that the software applies sharpness and this in my experience has been more evident with Olympus RAW data.

Really, is that why the Nikon D5 (flagship until a few months ago) has a filter. Are you saying that the images from the D5 are degraded because it has a filter. REALLY?

YES! Anti-aliasing filters are used to blur the lines between repeating patterns in order to avoid moire. Film grain was random, so repeating patterns did not result in moire. Digital sensor elements are laid out in a two by two square pattern in most cameras, which results in moire. Fuji sensors use a 6 x 6 pattern which offers greater randomization and avoids the use of AA filters. You do realize that anything designed to blur, will degrade your image. Most noise reducers do that also. The degradation is minimal, but it does exist, otherwise the moire effect would not be reduced.

Reduces moire patterns.
Unless you micro pixel peep there will be no visual difference in the photos produced as far as sharpness.
Nikon puts the AA filter on their flagship cameras for a reason.
Pros do not micro pixel peep.
