hello anyone have any input for which kind of adapter would be best to invest in given the follow wants (+) and want to avoids (-)? +a good macro +fast lenses (<2.8) +good character +autofocus (ideal, not a dealbreaker) +good selection of focal lengths +options wider than 30mm -excessively high cost -vignetting -zooms not required   been considering the mamiya and the CZ adapters, but am open to ideas for FF systems if you can recommend some with UWAs that don't vignette.

Buongiorno ho un 70 300 volevo sapere se è normale che faccia un rumore all'interno se viene scosso...grazie

Added in: I ran a quick check using an image folder from a small astro project I am working on. The folder contains 101 X-T30 full size raw image files each being stored as 55.9 MB files in size. These were all converted to FITS format using Siril, an astro-photography image processing program. It reads each image into ram, converts it into FITS format and writes the converted file back out to disk, these will be used for actual processing. So, for 101 55.9 MB  raw files ---> 101 52.1 MB FITS files, Siril reports that it took 3.68 (3,68) seconds. I am fairly certain the 10 Gb NVME enclosures can handle the larger 200 MB GFX files without any troubles, of course the 40 Gb enclosures can as well. https://siril.org

My goodness! I am so amazed this worked! Oftentimes, my technical problem doesn’t get solved, but this one did! Thank goodness to the peanut foil that was there when I was looking for a solution. Worked worked worked!    saved in my gdrive a copy of how it looked https://drive.google.com/file/d/1EJ41l09KMQL6ZV69QLA8rWaied6Dzumm/view?usp=drivesdk   thanks a lot!!!
