ASI2600 & ASI6200 flange backfocus distance is too long

Hibou

The ASI2600 & ASI6200 flange backfocus distance of 17.5mm is too long to use most lenses for non-astro imaging. Even with the 5mm leveling plate removed, it is still 12.5mm, and MFT (micro 4/3) backfocus is 19.25mm. MFT cameras are sufficient for many applications, even if the full chip area cannot be used. The ASI2600MM & ASI6200MM are cooled, 16-bit with no amp noise, and there is no ZWO alternative. (The ASI294MM has amp glow for 5 minute exposures, and the ASI432MM is not cooled).
Would it be possible to reduce the backfocus distance, with perhaps an additional compensating plate to maintain the existing distance for backward compatibility? Even an extra 5 mm for the ASI2600MM would be interesting. Maybe even optionally remove the dew heater ? For non-astro imaging the camera and lens must also be separated by the metal plate of the camera box, which makes backfocus even more difficult.

Since I didn't have a reply :-) I'll make a simple suggestion. A micro-4/3 lens adapter could be screwed onto a faceplate of the ASI2600 camera to allow the use of modern APS-C lenses such as those from 7Artisans with 19.25mm backfocus. The backfocus of the ASI2600 is already 17.5mm with the 5mm faceplate, so only a 2mm micro-4/3 flange could be added unless the backplate was made a little thinner. As a trial, I will use the flange from a cheap macro extender, and make my own thinner backplate, but it would be good if ZWO considered this simple solution rather than assume that people can use (obsolete) Nikon or Canon full-frame lenses on these cameras. ZWO already offer special faceplates for camera tilting.
