To be fair I'm personally not a fan of any straps, they annoy me.
The only one I use occasionally is one an old photographer gave me - he said it's a Zeiss strap, but I have never found any info about them. It's just a simple strap really, just alright for a SLR, but with a really nifty claft -
To be fair I only have one big camera and even that one isn't too big. Camera's are addictive! Especially cheap film ones.
