This 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.
