I have a Pinnacle M-25 with a 2 inch lens. I can purchase a 1.5 inch lens to use on my laser and understand that the shorter focal length has a smaller spot size and will produce more detail.
Does anyone use anything other than the standard 2 inch lens? If so, is the increase in engraving detail worth the cost of the lens (not cheap!!)?
The material I was thinking of using the 1.5 inch lens with would be marble/granite, metals and tile with thermark or cermark.
