Kenko DG Extension Tube Set for Sony E &nbsptype_Self Timer 5 is a good qualityThis Kenko set includes two extension tubes (10 and 16mm) which can be used separately or in combination to increase macro magnification. Compatible with Sony E mount cameras, full frame or otherwise. In excellent condition. Note that depending on the lens used and its tolerances, you may need to give it a slight wiggle to get the locking pin to seat on these tubes. No effect on function once seated, but FYI. In near new condition, with original box.
