CANON EF Auto Extension Tubes

with electrical contacts - AF works and EXIF is written correctly.


Much better solution to have the tubes after the adapter for my vintage primes - saves the hassle of having a set for every mount...


I prefer tubes to a bellows - much better to handle in the field...


Seen by my Carl Zeiss Jena Tessar 50mm ƒ/2.8 Alu 1Q (8 blades, 1960)

wide open @ƒ/2.8 | available light | manual exposure and focusing


Lens EXIF written with ExifMixer | ExifTool
