Thanks Bob, i did email them about what serial numbers they have in stock and whether they are expecting new shipments, but it has been nearly two weeks now with no reply, I may have to call them.
Do you have one? If so does it have the flash lag thing?
https://www.pentaxforums.com/forums/172-pentax-k-3/242556-k-3-delay-when-using-flash.html I find the flash lag thing quite extraordinary, I was going to get a K3 as the mirror flop thing is by most reports not that bad as such, but now i find there is another problem with delayed flash firing. A bit perplexing.
