Canon has improved the lens cap on the rear of its RF lenses. You heard that right, the Lens Dust Cap RF mark II. This might well be Canon's most popular new product in 2026. It solves an annoying problem.
What is the problem? When developing the new lenses, Canon's 'clever' designers had to develop a new lens cap. New bayonet mount, new lens cap. That is nothing more than normal.
It is essential that you align the lens cap exactly. Otherwise it will not fit. By comparison, the lens cap for the EF mount always fitted. Blindly. The RF lens cap does not. It only fits one way.

Now the Lens Dust Cap RF mark II is coming, and it solves this problem. It will be just as easy as it was with the EF lenses. You will once again be able to put the lens cap on blindly. Finally. The new lens cap will cost around 7 euros.
Since the 'old' RF lens cap causes so much annoyance for photographers who want to change lenses quickly and blindly, this new RF lens cap will be a real solution. I think it will be more than worth the (small) investment.

Don't want to spend that money? Then you can of course modify your 'old' RF lens cap. You need to remove the longest 'notch' with a hobby knife or Dremel. It is simple and saves money. It does have one small disadvantage.
When modified, you can tighten the lens cap in any position. In one of the three positions, the lens cap may be lifted by a millimetre. It is hardly a disadvantage, but it should be mentioned.

Are you going to modify your lens caps? Then do so at your own responsibility. If you use a hobby knife, be careful with your fingers. You do it at your own risk. Or order the new Lens Dust Cap RF mark II. The choice is yours.
It remains to be seen when this lens cap will become available in Dutch shops.
