I'm using a Canon EOS 100D, it's not so much the architecture but some of the interesting abstract shapes. The moire effect is hardly noticable in the full size image, it does make it worse resizing the images to fit the forum.
Yes, I struggled to get rid of it completely without losing all the sharpness in the image - the moire removal tool in my image editing software is a bit too vigorous and made everything blurred.
