I been used to adding sony files large 60mpex raw files adding them didnt seem to take too long , 200 images few mins .
but i have now using om1 .orf files 20mpex raw files seem to take 3 times longer to add even before i start processing anything , 200 images about 20mins just to add them .
work around
add files to lightroom first , then process through dxo4 plugin , alot quicker this way
