I've taken a Nikon SP with 8.5cm F2 and 5cm F1.4 to the beach. I'm fairly careful with them, use a sealable plastic bag and do not do this if the wind is blowing. I've not had them damaged.
Last month, me and my Nikon S3 went down the giant slides and Hay rides during a local Fall festival.
What's the point of having these classics if you don't use them?
