I recently purchased a Sony RX10-M4. I use it mostly for bird photography and it augments my Canon large lens setup, being lighter, able to create good images and be silent when exposing. I like the camera. The software however.... is totally unwieldly. I have my own method of organizing my images, one I have used for many years. I take only RAW images, then peruse in the Viewer, delete images I don't wish to retain, perhaps do minor editing (especially cropping) and convert some to TIFF files for further processing in Photoshop. I use a 4k monitor. The Sony Viewer is useless. The thumbnails are far too small and I cannot discriminate between images without selecting a single photo to view in the window. I have set the Sony to shoot at 10 fps and sometimes return home with more than a thousand images. My first edit is to delete images I don't like or which are duplicates due to the rapid fps. If I use the Sony Viewer, it requires about 5X the time as with my Canon viewer with which I can re-size the thumbnails. I have found no way to re-size the thumbnails on the Sony Viewer. Anyone know how to do this? The Sony Viewer displays 16 images per line and shows 9 lines, or about 144 thumbnails per screen. Far too small for my use. Most often the subject cannot be discerned in such small thumbnails. Out of frustration I DLed Capture One and quickly discovered that it can re-size thumbnails to a functional size - about 5 per line. However, its viewer does not seem able to delete images via the viewer. It also seems overly concerned with "catalogs" and I have zero interest in using their catalogs. I use my own organizational scheme. Anyone have any other suggestions? Sony seems impossible to contact to make a suggestion that their software incorporate thumbnail sizing. I did purchase Lightroom a couple of years ago, but did not like it. Too concerned with "cataloguing".
