I picked up a NEX 5 body incredibly cheaply in a job lot of camera gear. I got a battery and charger and it turns out to work, though it's cosmetically poor. I can't really justify getting a proper NEX lens since my only use for it is to occasionally test NEX accessories such as lens adapters, but at some point I might need to use one, e.g. if I'm testing extension tubes or a converter. It occurred to me that the cheapest option is probably to get an EF to NEX adapter. My question is, how well do they work, and are there any issues I should be aware of? Update 26/12/2020 - I found a Commlite Auto Focus Ef-Nex adapter on CEX for £25 plus postage so I've ordered that - should receive it next week hopefully. I'll post again when I've tried it.
