All Leica should have Dual SD slots

After my son got caught by SD failure (no valid image), I suddenly think dual SD  slot should be essential for all digital cameras, including low end P&S.

At least in all Leica. After all, no Leica is low end.

nice idea, but if the error is from the main board then most probably both slots would have SD failures

What did your son see when he checked images on his LCD from the beginning of his shooting? (I assume something was visible to him?) Did he have and use a spare card?

If he was travelling, at what stage did he realise that he had a problem?

On any of my cameras that have two slots, I use the second slot only for overflow or for storing a spare SD card :).

I had only once an issue with a couple of images on a CF card.

All cameras are compromises with something missed out for weight, cost or other reasons. In a consumer camera (most cameras) I am happy not to have an extra slot. I have never had a card failure in-camera since I went digital around 2001.

 

Q. What camera and card was it? Had the card been used without problems before?

When the photography is being paid for by a client and not repeatable in the event of a catastrophe, I would not use a camera without dual card slots or enough internal memory to cover me.

In the last 24 years I've had one early days 1gb microdrive fail and one Lexar cf card fail.  Not a high number by any means, but enough to put some value on in-camera backup.

I cannot remember a dual film camera. It were tough back then🤔.

I had two backs for my Hasselbad then.

So did I - but generally with different films in them. And unless you shot everything twice they didn't help save images either.

I have dual slots in the medium format cameras, but not in the Ms -and do a lot of work with them too-.  Yes, it is a risk. I travel with a laptop and save images from the cameras every evening.  But said that, so far I have never lost information on a card, but I have lost a full external drive -a Lacie- once. i was able to recover the files but it cost me a fortune.  Since then, I keep a NAS, and a backup storage in Azure.

I'd rather have an internal SSD a-la-M11.

Im in the other camp for a few reasons. First I hate cables to begin with and with the latest usb garbage there are too many variants. Much happier to just pull the card and stuff in the MBP slot.  The other thing is related to failure. Yes, cards fail as well, but they're replaceable and at increasingly lower cost as time goes on. SSDs have a limited number of write cycles.  If the internal mem is of the highest quality, nothing to worry about for a very long time, but if not, if could fail after a few years.

Never had failed card in camera. Since 2003.

Had few crappy cards which propagated their quality by purchasing place and price.

For those who needs two, here is SL series.

Pushing two cards readers into M and Q is not realistic. Those cameras meant to be tiny.

Two slots, micro-sD  See what phone did with the SIM/Micro-SD insert slot.

Dual slots maybe, but incorporate an CF Express Type A card holder that is backward compatible with SD cards just as the Sony A7S III does.  CF Express technology is superior to SD technology, but at a price.
