My aperture plates are sliding out of my lenses, what should I do?

Petzval 58 and Petzval 85 aperture plates are designed so that you can adjust each one to perfectly fit inside your lens. Using some pliers, simply bend these two small parts on each side and this will prevent any possible slippage. Be careful not to bend them too much so that they still fit.
