The Sandisk SD cards I used were rated at 170mb/sec.Originally Posted by Kayaker72
BTW...as much as I love gear, can we focus on this for a second....that was a 1D MK IV with its 16 MP APS-H sensor from 2009 and a 500 f/4 MK 1.
Another smart choice, I rolled up with my CFExpress cards for my R5 with their 1500 MB/sec speed...Joel? UHS-I SD cards. Not even UHS-II. As I heard it, he never filled his buffer while shooting on the R5. Only drawback was downloading speed at night, which isn't really even much of a drawback.
You do not need the latest and greatest to take amazing pictures. I still maintain you need good gear, but it doesn't have to be the latest and greatest.
A lesson I may never truly learn.
Since I like to use the crop mode quite a lot on the R5 which provides smaller file sizes (but very adequate for my needs) I thought that these inexpensive cards would perhaps write 8-10 frames per second to the card.
I rarely hold the shutter down more than 2-3 seconds. Turns out it worked just fine. Never hit the buffer limit as Brant described but download to my external drive was a bit slow.
I already had 3 Type B CF express cards (64 gb each) as well but didn't want to buy more for this trip
We did a total of 6 shooting sessions and I used one card for each session: 3 64gb CFExpress and 3 128gb SD1. None of the cards were full. I was shooting around 1200-1300 shots per session.
I was also shooting a 5DMIV with CF cards mostly on the perched birds..... still produces great images.
I downloaded each session into separate folders on an external drive and I kept the used cards sequestered as well.
Once I get through my files I will eventually re-format the cards for future use.
Might be a different experience for someone who likes to use a "machine gun" approach.
