Been used pretty much exclusively in a studio for product (jewellery) photography. The high shutter count (322,044) is due to focus stacking when capturing the jewellery. In one photo of a product up to 100 images are taken slowly to create a deeper depth of field. No high drive mode has been used on the camera so even though the shutter count is high it has been done slowly without stressing the camera. Sensor is perfect, creates incredible images.
