I understand the new Z6 and Z7 will
have dual card slots, which has kept the previous models out of the hands of
some professionals.

What is the second card slot needed for? My camera has two card
slots, but I've been using only one for the past years.

write to both cards as a backup (important for pros), put raw on one
and jpg on the other (pointless, but people do it anyway), or
automatically roll over to the second card when the first is full.

They can be configured in different ways. You can have double the storage, one
for RAW the other for JPEG or, as preferred by professionals, one will be a
backup of the other.

But is all that really needed, given that there are huge memory
cards (1TB) and the professional will backup the images on the
computer anyway?

the backup protects against card failure.

if you're writing to one card and it fails, you won't have any images
to back up on the computer.

with a second backup card, you will.

it's basically a raid-1.

2 slots is like an extended warranty; most experts in commerce will tell
you it's a waste of money, and the math proves it.

utter rubbish.

100% correct. Until you lose a wedding shoot, or something else, where
“shoot� becomes what the client does to you.

I have my Nikon D7200 configured with a pair of cards in the backup
setup. Possibilities:

- One card fails between the time it's inserted in the camera and when
you complete the download of pictures to the computer and their backup.
You still have your pictures.

- On the Nikon, if you delete pictures, it only deletes them on the first
card. Thus, you can 'delete' pictures, show that they're 'gone', and yet
still have them. Or you're reviewing pictures and stab the wrong button.
Oops! Oh, wait - still have it.

Perhaps I'm lucky, but in over 20 years of use (have been using
digital cameras since 1997) I've never had a memory card fail in
the camera.

Other things have occasionally failed over the years (e.g. the
flash hotshoe contacts got exidised, lens AF of Sony lenses
broke a number of times), but memory cards have never failed
(not even 20 years ago, when the technology was new).

So, while I'm not complaining about this second memory card
slot, if it didn't exist, it wouldn't make any difference.

By the way, on a side note, I've never had a camera body fail,
but I've experienced problems with Sony and Tamron lenses for
the Sony A mount (the AF failed). On the other hand, I've been
using m4/3 equipment over the last 4 years and everything is
still working fine, so I guess Olympus equipment is quite
reliable.

on any camera or computer, delete just marks the file as gone.

use a recovery tool and they're still there, as long as you don't shoot
any additional photos (unless you get lucky).
