p.6 #1 · p.6 #1 · Olympus E-M1 MKIII Hands On, Tips and Images


I am just about to buy a E-M1 MarkIII for BIF photography but I am not sure what speed of UHS-II card to buy. I don't want to limit my burst speed by getting a slow card but I also don't want to spend a mint on a card that is overkill for the camera. I know that one of the SD card slots is UHS-II and the other is UHS-I. I have read that you can backup to the slower card when your not shooting and that seems like a good option for me.
So what speed of UHS-II card do you use?
Thanks
Karen

While having the fastest 250-300 MB/s read and write speed cards might be nice, they are expensive and really not needed. For both my EMI MkIII and Sony A7RIV, where I shoot raw + jpeg written to separate cards, I use the Sony Tough series M cards, which are 275 MB/s read and 150 MB/s write speed. The write speed is the important one as that is the speed the card can accept sensor data. Only the best UHS-1 cards top out around 90 MB/s write, most are much less, so UHS-II speeds can be significantly faster. But the camera also has to have fast transfer speed internally and somewhere last year I read a review that the EMI MkIII internal speed was in the 145+/- MB/s range, so any card that is faster really won't improve transfer speeds. Same for my Sony, it is in the same range internally. For this reason I bought the M series and not the double the write speed G series @299 MB/s, it seems to be money wasted.

The Tough Series is Sony best card, being waterproof and dustproof, and even though only slot 1 of the EMI MKIII is UHS-II speed I bought UHS-II cards for both slots for convenience and instant backup if needed, knowing the 2nd card can work at fast speeds in slot 1. Never had any issues with buffer slowdown, but then I never shoot at 10FPS for 5 seconds or more. Other than the speed rating the G and M series Tough cards are identical and carry the same 5 year warranty. The Tough M series cards are about 1/3 the cost of the Tough G series cards, B&H and others has the Tough 128GB M cards on sale for $60 where the G series 128GB card is $190!! The Tough 64GB M card is $40 vs $100 for the G series. It's $100 for a pair of M cards vs. $290 for a pair of G cards, yeah, that's a savings

I put the 128GB card in slot 1 for raw/rare movies and the 64GB card in slot 2 for jpeg. I can shoot about 2,500 raw photos with this setup and have an instant backup large size jpeg. Writing raw files to the 2nd card slot, being only UHS-1, is what will slow down the buffer, so try to avoid that.

For Video, the M series has a V60 rating where the G have a V90 speed, but both cameras work fine with V60 cards according their specs.

p.s. Sony makes a non-Tough M card that is the same speed, a bit cheaper, but not rated to be waterproof or dustproof. Since the EM1 MkIII is rated for these conditions, I feel the SD cards should be rated too, so the 5 to 10% savings is not worth it to me.

Wow, this was just the info I was looking for. I couldn’t find the internal write speed for the camera anywhere. Thanks for all your suggestions. Great advice for buying SD cards
Cheers

That's not quite how it works. You're correct that the E-M1ii maxes out at ~160 MB/s but that's with cards rated at 300 MB/s write speed. Slower cards like Sony M or Lexar 1000x which are rated around 150 MB/s write speed only achieve ~80 MB/s. Also, with each generation the card speeds are finally closing in on fully utilizing the write speed capabilities of these cards. The Canon R5, for example, is currently the fastest with UHS-II cards at ~220 MB/s write speeds and I would hope that whatever Olympus comes out with next at least matches that.

I understand that the faster G cards will have a faster write speed time up to the cameras internal transfer limits, but does it really matter to most, certainly not to me. As I said in my post above, I don' spray and pray shoot so taking 10FPS for 7 or 8 seconds, where you would see some slowdown in buffer speed writing near the end, is something I don't do. Thus while the M series of Sony Tough cards may only write internally at ~87MB/s I will never see any writing speed gains by having a G series card capable of writing at the camera max speed. If someone does this type of shooting, or in the case of the Sony A7RIV 61MP's, shoots uncompressed raw where the file sizes are near 100 MB, then by all means pay 3 times as much for a G series of card. But with the EM1 MkIII file size around 22MP this is much less of a concern. And both the EM1 MKIII and Sony A7RIV are rated for V60 cards for video, which the M series of cards are rated at, so having the V90 rated G cards it seems will not add any speed. (but I am not a video guy).

Typically I have my EM1 MKIII set to AF-C mode at 3FPS for people, or 4 for wildlife/airshows. Just to show what is possible at 4FPS, last week I returned from a 7 day trip to Loreto Mexico, located in Baja Sur about 2/3 of the way down the peninsula. Was photographing some high flying, cruising Albatros from a boat when we ran into a big pod of dolphins, estimate 200, and took short series of shots of the dolphins jumping as shown below, a quick 7 shot 1-3/4 sec burst.

I shot multiple instances of dolphins jumping one right after the other. Shooting at 4 FPS with "only" a M speed card caused zero issues, there was no waiting for the buffer or any slowdown to the camera.
