Excellent for Engraving
Swapped this lens out for a 50.8 lens to see if it improved the engravings I was doing on cork coasters and WOW! The detail and crispness is amazing. The 50.8 Lens was doing a very nice job but nothing compared to this lens. Running it on a Light Object full setup, tube, X-Y stage, power supply and 708/LO-X7 controller at 500mm/s at 11.5 on power. Great product, especially for engraving like the ad states.3/16/2016
