My Dad's Old Kodak Retina 1a from early 1950's

Shot with Sony A7R2 and Nikkor 105G Macro 2.8 and Fotodiox adapter. I shot a few shots at different focus areas and then in photoshop it can automatically find the focused areas and layer stack the image. Then it's all in focus! Crazy! That's how you get more depth of field with extreme close up work.
