Do you FORMAT your cards IN the camera you are currently using them in.... they donít swap from camera to camera .... as far as I know, each make of camera write/reads them differently.

Never format them on your computer.

Other members may be more savvy about it than me.

Never had any problems with card readers and getting cards out of cameras.

Is there a valid reason for using card readers? I have never used a card reader, always downloaded the images by plugging the camera into the PC and using Adobe Bridge (or Lightroom), which seems to me to avoid so many problems. The only time the card comes out of the camera is if it is full but even then it would go back in the camera for the images to be downloaded.

I've used card readers for years and have never had a problem.

Many years ago I used a card reader but they were badly designed and the pins bent. This happened twice so I stopped using them and leave the cards in the camera. I thus upload from the camera directly into Lightroom. This is very straightforward and I now wonder why I ever bothered with a reader. I have always used a good quality card normally SanDisk and never had the slightest problem with them.

My current computer has an SD card slot and that is what I use and it has been working OK

No need to have the camera switched on, cable across the desk etc.

I have used a card reader for years without any problems. I used to plug a cable into the camera but the socket collapsed within the camera and caused the camera to cease functioning. The repair was quite expensive.

Cards can be swapped from one camera to another.

Some years back, my wife forgot to put a card in her camera before we went out for a walk. For the next couple of hours, we swapped the CF card between her camera and mine. The images just went into the appropriate folder. Is it just Nikons that make a folder without being prompted?

This will not resonate with many of your comment providers but you will only ever bend or damage a pin inside an expensive camera once. I sadly did just that with a card in one of my earlier digital cameras and since then have used the connecting cables, supplied software with my Nikons, and the windows system to copy and paste with the other odd ball digital cameras I buy and try. I do reformat the cards in the nikons from time to time but I was brought up on compact flash cards and the lessons learned have stayed....Dust damp and wear and tear are in my book the enemy of electrical contacts and the interior of card slots are a no go area...............Just one of my photo foibles I know but hey........ its sunday morning and still lockdown!

A camera club member used to work for the local Jessops before Peter Jones bought them and he told me that bent pins was one of the most common faults in cameras taken to them and it is an expensive repair. While I have used cables for many years now. I notice that my most recent camera Canon 5D4 has a guide which ensure that the usb connector is guided accurately so there is little chance of damaging the connector. I have had the camera 3 years now but I do not think I have ever removed the two 32 G Byte cards. I do carry some spare cards but the capacity is about 630 full frame raw images and I have never yet exceeded this in a single photoshoot.

I've always left the card in the camera to avoid problems with bent pins or just plain wear and tear. Photos are uploaded by wi-fi or by cable using the connector provided which is designed for frequent connection/disconnection.
Card reader ? Why risk it ?

Something over 90% of electronic problems are caused by bad connections. When I went to use a camera to do some Fleabay snaps, it wouldn't recognise the card. A quick squirt of Electrolube Switch and Contact Cleaner did the trick.
