"We can remove the AA filter and replace with an optical window with the same refractive index (so that focusing and aperture settings don't change). This allows the camera to perform at its full resolution with one possible drawback - Moiré patterns. However, most photographers would prefer to deal with the occasional Moiré problem by fixing it in Photoshop and are happy to maximize the resolution of their camera.
We can currently convert many different Canon, Nikon and Olympus cameras to HR.. The cost is $450 + return S&H ($20 UPS ground insured domestic USA). We only need camera body, charged battery and cover letter requesting the conversion type. Turn around is usually 1 or 2 days from receipt. Conversions are done in our Class 100 clean room with ionized air and static control surfaces. We have been in business since 1997."
