But there really isn't a bad Cron in the bunch. Personally, having had all the Crons from collapsible on up to the latest, my favorite is the 11819, so-called "tabbed" version with the same optics as the current version. The 11817 is less flare-prone, and definitely has better coatings, which are the achilles heel of the earlier versions as they were quite soft and easily damaged. Although the 11817 head does unscrew, I maybe wrong but AFAIK it was not meant to do so except for repair/adjustment, and it either won't fit or won't work properly with any other focusing mount.Īs for performance, the 11817 gained contrast and center sharpness, but at the expense of a slight loss in resolution across the field.
