A 6D2 with one slot would be like buying a BMW with roll up windows...
lol, quite an exaggeration there!
I use a 1DX and never shoot to both cards simultaneously no matter how important the event.
Sure I could have a card fail on me, then again I could have two fail on me, or three, or the camera might break, I might even get run over by a bus, hit by lightning or....
If you are so concerned about losing data, buy extra cards and swap them out frequently, it's not that big a deal and if you are going to do that you can buy smaller GB cards which are also cheaper.
Congratulations on your lucky streak. Others are not so lucky. Remember, it isn't a matter of IF, but WHEN. Memory cards, as good as they are - still fail or corrupt. It's rare, yes I admit that. But it does happen. Usually at bad times too. Funny how that works.
It also depends greatly on the type of event. If you're at a race track and the mission is to capture images of various cars flying by - your method works fine for a single card slot users. Take shots on card A, then take mostly the same ones on card B. You have the flexibility to capture what is going on at an event, rather than key moments at an event. Only downside is, shooting the same or very similar stuff to two cards is a waste of time and redundant.
Then there are some events where this is impossible. Like a wedding. Good luck getting the first kiss or bouquet toss on 2 different cards with a swap. Not enough time. This means critical, key moments of the event, which are NOT reproducible, will reside and exist on a single card until they are uploaded to something. Also, the critical portrait/family shots, the ones that mom will cherish and frame up - you are going to slow down the shoot by doing it 2x over? Or doing it once, but stopping to swap cards for each portrait?
There are plenty of arguments of absurdium like the camera could fail, tornado et cetera. Great. Because any number of infinite, but remote possibilities exist, one shouldn't bother with a simple safe measure like dual slots? That is illogical. If the camera dies - you will know it right there on the spot, and you can then use your backup camera. If it is a critical event, yes, you should have a backup camera. And NO, a backup camera is not a substitute for 2 slots. Two single slot card cameras solves nothing. Just to be clear, the 2nd camera would be worn on body, not out of reach. It is very fast to deploy, and you have a high probability of still getting the critical moment. To be fair, the only way to be completely rock solid is to have 2 shooters, with dual slot cameras going at it for critical moments. Thus, to lose the moment would require the failure of 2 cameras at the same time, or 4 cards. Almost statistically impossible. That's what you want, minimize the chances.
People put wayyyy too much faith in the reliability of memory cards.
So it depends on what latitude of freedom you have at your event. If I'm shooting for some blog that wants photos of a local festival - no problem. 1 slot will do it and I can swap and get a collection of what I need that spans a few cards, the majority of which will allow me to produce to the client sufficient material in the event one goes down. However, what will I say to the bride when I do not have a shot of the first kiss? Tell her sorry, my Lexar/SanDisk corrupted.....This destroys reputations, is unfair to the client, and irresponsible.
For $2,000 or more, Canon should offer dual slots as a standard feature. They offer on the 5D3, 5DS, 7D2...and even video cameras like the G40...Gee, why do they do that? Use the reverse argument. If it is so safe to have one slot, why bother even on these cameras? Do away with dual slots entirely.
Given also that Canon can economically place 2 slots on the 7D2, and given its current price point - it is totally unacceptable they put 1 slot on the future 6D2. There's no logical, reasonable reason of any kind other than they are doing it to cripple the camera. To deter people from using it in the most serious moments as to instead opt for and buy a more expensive FF camera....
Push the suckers up to a 5D series. That's all.
