Good combo lens if doing engraving and cutting within the same job.
Normally buy my miniscus lenses from cloudray, but didn't have time to wait for their shipping times due to the Christmas rush. Had heard good things about this brand on a Facebook page, so thought I'd give them a go. 2" focal length lens has been perfect for my 50w. Not tried this brand on the 80w, but on the 50, I'm getting really good detail on engraving veneered MDF and really clean cutting lines on up to 4mm MDF/birch and 6mm acrylic. Really good combination lens. Can't speak for longevity, but has survived the last 2 weeks in the Christmas chaos and still looking as clean as new.
