Takahashi announced a new version of the FSQ-85, the "EDP" model. The new FSQ-85EDP will be replacing the currently available FSQ-85EDX.
Here's the news release in Japanese with photos: http://www.takahashi..._fsq-85edp.html
From my initial assessment, the new FSQ-85EDP appears significantly improved over the current FSQ-85EDX if you will be imaging with a CCD or DSLR camera that has a full frame sensor. There are probably not enough differences for current FSQ-85EDX owners to sell theirs and upgrade to the new EDP version, but if you're about to pull the trigger on a new FSQ-85, I think its best to wait a few weeks for the FSQ-85EDP to hit American shores. I've heard late November is when it will be arriving.
The above article is not available in English, so i've translated the Japanese text into English, its not perfect and i'm still a bit confused as to some of the specific features, but you get the idea:
"Although it is FSQ - 85ED which has gained popularity as a compact photo visual machine, we changed the specification of the eyepiece section for this shooting. This makes it possible to connect the camera by preparing the camera mount DX - WR. APS - C size was mainstream at the time of the launch of FSQ - 85ED, but recently the number of users to image with a full - size digital camera etc. has increased, even with this class of caliber the Petzval type personality, Aberrations came to be noticed. By using the flattener 1.01 × previously released, we can correct the light field curvature at the focal point and the astigmatism almost completely to the full size range, resulting in a flat image plane. With the FSQ - 85EDP, you can also connect the flatner 1.01 × if you have the camera mount DX - WR. Up to the eyepiece adapter connecting ring (FSQ - 85ED) connected to the draw tube is the same as FSQ - 85ED, but behind it is the camera rotating device (TSA - 102), the filter box auxiliary ring TSA - 102), CA - 35 (TSA - 102), eye view adapter (CCA - 250), eyepiece adapter connecting ring (short), 31.7 eyepiece adapter. The camera mounting DX - WR is attached because M54 P0.75 is where you removed the eye view adapter (CCA - 250). FSQ - 85EDP is a lens barrel that planned and designed the optical system with consciousness as a compact machine, and focused on φ44 mm which is the full - size image circle from the center. Although it is a sharp star image from the center of the screen to φ20 mm or so, it is somewhat less flat with about 30 microns in φ44 mm (4 corners of 35 mm). At the time of the launch of FSQ - 85ED, it was an optical system that was necessary because it was the mainstream of APS - C size digital single lens reflex camera and cooling CCD. Recently users increasingly use digital cameras and CCD cameras with full size or more to increase the number of users to take pictures of the Petzval type even in this class of caliber, surrounding astigmatism has become noticeable. By using the flattener 1.01 ×, the light field curvature and astigmatism at the main focus are almost perfectly corrected to the full size range, resulting in a flat image plane. Although the focal length slightly increases to 455 mm f / 5.4, the sharpness of the central image unique to FSQ - 85 EDP continues to the full size area, the image circle is small but sharp optical FSQ - 106 ED is inevitable You can upgrade to a system. Reducer QE 0.73 × is used, the focal length and brightness are the same as the camera lens of 327 mm f / 3.8, and the aberration performance exceeds the high performance telephoto lens. It is a star image of 30 microns or less even per full-size four corners (φ44 mm)."
