An old shell I don't think I would even try to fire it. That thing is ancient. 50 mm lens with aperture control used as an extender.
Taken for this week's Macro Monday challenge. Lots of numbers and letters describing the characteristics of the objective. !0 is power (magnification, 0.25 is Numerical Aperture (equivalent to depth of field in photography and determines the resolution). Ph1 is the phase ring size and DL refers to how well it works for enhanced contrast. Plan refers to the extra glass in the barrel to flatten the field and remove the curvature caused by the magnification lens element, and 160 is the path length (in mm, essentially infinity optics for this lens). From an old microscope - a Nikon Labophot. Shot handheld with natural light obliquely lit.
I use this ruler to measure my macro subjects for this group. It's an antique Lufkin L shaped ruler. This side is 4 inches and the other side is 3 inches. it's perfect for this group.

iPhone 3G running iOS 4.2.1. Amazingly large and easy to see pixels. And it still joins my WiFi. Can’t add an email account, but I can still browse the web.

J'ai ressorti mon alarme de voyage du placard et c'est avec regret que je me suis rendu compte qu'il ne fonctionnait plus. Que cela ne tienne, son habit chromé me donne l'occasion de le montrer avec fierté. #Macro #MacroMondays #NumbersAndLetters
