I’m curious what people’s thoughts are on this.

I’m a fairly new photographer and have done some pro-bono work with an EF 24-70 2.8 l lens adapted to an R10. The photos were a hit and now the client is offering to pay me to work a few upcoming events for them. I’m definitely going to say yes, but am now wondering what I should do with regards to redundancy - the R10 doesn’t have dual slots and I don’t have a backup digital camera. These events aren’t exactly high pressure, but I don’t want to fuck up the first opportunity I’m getting to get my foot in the door for paid work. Some of the ideas that have popped into my head:

• Rent a full frame R series body and use my R10 as a backup
• Buy a cheap used DSLR to use as a backup until I’ve saved enough to buy a full frame camera of my own
• Bring one of my EOS film cameras as a backup (this seems absurd to me)

Any thoughts?
