How important are dual card slots?

I've never had a card fail on me (knock on wood) the past 16 years. I don't have a second card in my X-T2, X-T3 or nikon D850. In my Nikon D800 its only for the videos. I bought the Z6 and I don't care it doesn't have a 2nd cardslot.

I usually have sandisk, but 've also had IBM's microdrive, Toshiba's, kingston and Transcend.
Same here, the only card that made me some problems was a Kingston about 10 years ago, it was slower and slower and some photos disappeared, with Sandisk and Samsung cards I have no problems at all
The point isn't whether you've had a card fail or not - I've never experienced it either. What is important is:

a) Can cards fail? (Very?) Rarely, but yes, it can happen.

b) If a card fails, what is the impact for you? Depends on the number and significance of the images on the card I guess.

c) Are you willing to take the risk? I am not a pro so unless I'm on that once in a lifetime vacation, I would probably be OK with a single card slot.

d) What is the cost? Does it force you to go over your budget or against your body preference to get dual card slots? I am fortunate that I like the X-T models, regardless of dual slots.

To put it another way: do you wait until you have a house fire before buying home insurance?
A house fire loses your home & belongings, a card failure loses you some images.

Maybe do you need a spare wheel in the trunk is a better analogy ;)
Well no, depending on what those images are and how important/irreplaceable they are to you or a client etc, the house fire might not be such a wild comparison.

A flat without a spare tyre is a pain, but it’s a recoverable situation - you can get another tyre, call for help etc, you will get home and the car will be fine, you’ve just been inconvenienced that’s all.

If you’ve just shot a wedding and the card fails/gets wiped etc - yes you might be lucky with some recovery software, but you might not. Whether you have a spare card or not isnt going to matter if the images were only on that one card that failed.
And....
Not sure if you think you’ve made or clarified any particular point with that. Bottom line is, if you really don’t feel your images have any value at all even to you, then sure - losing them is just a minor inconvenience, like having a flat and no spare tyre in the back.

But there again, if you do genuinely feel that way... maybe the number of card slots in your camera is the least of your concerns anyway. Why own a camera at all?
 
The answer is simple. For wedding photographers two slots are important, for everybody else not important at all.
You mean it’s not important to you at all, you don’t speak for me, thankfully.
2 card slot is good to have. U can use the 1st or the 2nd or both... Memory is so cheap today that u can back up everything...

I am a slow shooter cos I hate playing find the difference with 10 images that looks almost the same. So 1 card slot is good enough.

Been shooting digital since the day of 2 images on a 3.5inch disk(don't even rememeber what it's called now) ...to cf to micro drive to memory stick to SD... Non had failed me...guess I wasn't annoyed enough to want 2 slots.
And that’s what works for you, but it doesn’t work for me. For important photo shooting 2 slots is a must for me.

Interesting advice. Not good advice in any way IMHO... just interesting. So, unless you're a wedding photographer, having a backup for your images isn't really important then? Therefore, when I'm on the ship returning from that once-in-a-lifetime trip to the Galapagos Islands, for example, and I'm unlucky enough to have experienced the sort of failure and loss of images described earlier in the thread, then by your measure it's all OK, right?

So, I might suggest that the answer might be very simple for you, since the possible loss of irreplaceable images is no big deal. But for many of the rest of us, the images we capture as part of our little hobby are really important, as many of us value them highly alongside the memories we take back from our travels. Also, if you're a working pro in a whole range of areas beside wedding photography, the loss of images could be a career impacting event.

So, maybe you didn't think this through, or perhaps you're simply blind to the importance that lost images might have to many people who are serious about this little hobby of ours. But honestly, I would suggest that your statement is pure bunk, to be blunt, particularly if you think it applies to a lot of individuals besides yourself.

Nice try, Fujifilm.

I picture you nearly in tears.

That's why I keep the tissues close at hand. :-)
 
With my T2 and H1 I never had any card error (Sandisk and Lexar)

I use the slot 1 for FJPEG and RAF, the second for video clips

It is also a good solution in case the first one is full you can manually switch quicly to the second.

Finally it gives you a huge autonomy of recording space when needed (trekking for ex)
 
I guess if you are only a hobbyist, dual slot is not a MUST have. However, if you are paid to take a picture. Dual slot is a must. What will you tell your client if their wedding picture is corrupted and you got no backup? I will not gamble and hope that my card will not fail.
 
The first time, I recovered my images. The second time, I lost loads of photographs from a trip I took to Italy. I still miss them. The third time, I had a dual card slot, so I didn't miss a beat (though I only have JPEGs, as I set them up as RAW plus JPEG)

A lot of people think that SD card issues are software related. That was true of two of the issues I had. However, one time I dropped the card. I don't see any way to avoid that risk, apart from dual card slots.
 
That was a tack sharp piece of advice...high res, better than FF or MF, indeed, probably this is the reason why Fuji has implemented several options for 2 slots management...

I haven’t had a card error since the early 2000s, where I had several on everything from usb sticks to cf cards to sd cards. Not saying it’s still not possible, but the tech for these has come a long way.

However, if I was shooting event photography with somebody else’s money on the line, I would want dual slots for peace of mind.

I’d also want a weather sealed body...and a fast 2.8 zoom...and a backup body.....these are all things that ensure I would get the shot, but things I don’t actually use these days.

A card is not the only thing that can fail. I would like to see the reliability statistics concerning card failure, camera failure and lens failure. I expect after infant mortality has been eliminated (and that's easy to do - never put in a new card at an important event) the card is less likely to fail than the camera. In reality event photographers should always have a complete backup system ready to go - two card slots or not if the images are that important.
 
When I shoot events I now match the camera body models make it way easier on many levels from ergonomics to button layout and features are the same. In some cases to keep the batteries the same as well

A second camera body is more important than a new lens if that is a next buying decision. Then I rank flash and lighting , tripod or monopod then a lens.
 
Think about it as an insurance..

People buy car insurance but many times they have never had an accident.

However, just as insurance, you only buy it when the loss would be catastrophic - car, house, health, wedding shots.

I find that photographer failure for me is the highest one of all - failure to change focus mode, failure to notice a distracting element in the edge of the frame, failure to choose a correct shutter speed for the occasion, etc. etc. I had fewer of these failures when it was just my FM and me - only one ISO at a time, shutter speed and aperture. Focus was easy to achieve. These modern marvels are like a fighter jet cockpit for me. (Well, really, I quite enjoy the technology. But I do find that I have to be on my game.)
 
Risk assessment requires evaluating both the likelihood of a card failure AND an assessment of the potential impact if one was to fail. While the probability is low, the impact with today’s mega capacity cards can be catastrophic for a pro shooting a critical event. This also partly explains why dual cards is a more recent trend.
And also why I don't use large cards.
Multiple 35 mm rolls instant of the mega backs saved a lot of peoples butt when there was a screw up in the dark room.

Cards are cheap - especially low capacity cards. And you know what they are a lot more unlikely to fail.
Yep.
I got good advice early on. When using 35 mm use the 24 exposure rolls vs. the 36 exposure rolls. Sure you would be changing film more often but if you lost a roll, you would lose fewer images. Some people want the "latest thing" - why use a 16 or 32 GB card when I can get a 128 and can take three days, a week, whatever, without ever changing cards. But all your eggs are in one basket.

Yep, it's too easy to screw up. With my M4, I could whip it out and have zap the focus, probably as fast as AF and fire the shot. I knew what the settings were because there were only three and the ISO didn't change. I could have a shot from camera hanging at my side or pressed against my chest by a strap in about 1/2 second. Didn't have to look at anything, didn't have to worry about accidentally moving an EC dial, didn't have to worry about my fingers or thumb accidentally pressing a button. Wham bam, thank you mam, I'm done. The camera didn't force me to pay attention to it - I could concentrate on the scene and when the composition was right - bang done. With my digitals, I've taken to turning them off right after a shot and turning them on right before. That minimizes an accidental configuration change, with the exception of turning the EC dial - it turns with the camera off. Fuji should really put a press lock on that puppy.

EC - well open the aperture up one or close it down one. Or simply change the shutter speed as you survey the scene. No problem - no accident. On the Pro2, I have disabled the video button - since it is too easy to accidentally trigger. On the H1, I've disabled the Q button for the same reason which means I put the camera to my eye and see this flipping menu that I see no need to ever use - not my scene and potentially miss a shot. At some point I suspect I will dump my Pro2 and pick up an M10 or whatever follows that. Of course that depends on the direction Fuji takes with the Pro3.

I don't dislike automation and/or features, I dislike a camera that makes me pay attention to it. Today's digitals are like high maintenance girlfriends - "pay attention to me." I don't often want to pay attention to my camera - I want to pay attention to capturing my vision not interfacing with my camera and making sure I didn't accidentally change something that is going to give me heartburn after the fact. After all a decisive moment only happens once.

Technology should be there to help you not force you to pay more attention to your tool than your vision. Of course none of the camera companies have yet to figure out how to do that very well - except maybe Leica with the M10.
