In a recent thread I was advised to try out the U-ULC condenser to enhance the quality of photography at low magnifications. Here is a test I performed showing why I cannot justify $700 on a U-ULC condenser if it makes NO difference to swinging out the TLD condenser in the universal condenser assembly. All photos straight out of the camera - no processing applied.
