Canon Extension Tube FL 15

This tube let me get much closer with my old 55mm lens than I thought possible, and the breech-lock connection feels just as solid as on any of my vintage bodies. The metal construction has held up perfectly for something this old, no wobble or play at all.

Finally, my old 50mm lens can focus close enough to photograph small details, thanks to this extension tube. The breech-lock ring clicks into place solidly, no wobble at all.

Bought this to pair with my 50mm f/1.4 and the breech-lock mechanism clicks on just as solidly as the old lenses do. No light leaks, no wobble, and the extra extension makes close-up flower shots way more fun than I expected.
