As a seasoned photographer with years of fieldwork under my belt—from weddings to wildlife shoots—I've lost count of the lens caps I've misplaced. It doesn't matter if you're shooting with Nikon, Canon, Sony, or Pentax; no major brand offers a reliable solution to this frustrating problem.
Luckily, I've discovered and tested a brilliantly simple fix that's become my go-to recommendation for fellow pros and enthusiasts alike.

Simply attach a LEGO brick to the outside of your lens cap and another to the wrist strap lanyard so they snap together perfectly. LEGO's interlocking design is whisper-quiet during shoots and resists dirt buildup far better than Velcro ever could.
Now, in the heat of the moment, your lens cap stays right where you need it. Remove it? Just clip it to the strap's LEGO piece. It's foolproof, cost-effective, and has saved me countless replacements.
Simple, practical, and battle-tested!
