What owner's manual. He's looking for cards to go in an X-H1.

Tony is right. RFM and choose the recommend cards. Your camera will then limit performance.

I’ve seen that a card rated for HD video in your camera manual would be the "fastest".

Reading the manual is fine, but a couple of caveats: first, since the manual was written, card technology may have evolved. This is especially true of cameras that have been around awhile, plus while most manuals have a table showing max file and burst size, they rarely if ever show the write speed of various types of cards. There’s no substitute for a benchmark (which is readily available for many cameras just by Googling “fastest card for (your camera here)”. There are a number of reasons to pay the few extra $ for fast cards even if you don’t typically shoot long bursts, including: (a) the faster read speed will improve download to your computer (not trivial if you have a full 32 GB card), (b) you may decide in the future to shoot video, which can be very demanding, and (c) the next time you trade up or buy to a newer/faster camera, you won’t also need to upgrade all your cards to enjoy the extra write performance. The cost difference just isn’t that much...

But only to a point. Beyond that, you are just wasting money.

Billnikon is right on with his advice. If you are shooting BIF it's the write speed that will determine when the buffer is full.

User ID

Bill is correct but I think you read him incorrectly. There could be ambiguousness to his syntax but .... where he says his d500 buffer is 200 frames I do not read that he credits the card for that. The buffer is in the camera’s CPU and so the 200 frames is courtesy of Nikon, not Sandisk.

If he used a very slow card he would still have a fast 200 frame buffer but at about the 198th frame the buffer is full and starts dumping to the card ... and THAT is where things can slow down or even stop.

A card is NOT a buffer. Buffers are very brief storage and cards are long term storage. When the buffer is filling the card is doing nothing until either the user stops the burst or the buffer gets full during the burst. A 200 frame uninterrupted burst is usually at least 20 seconds for an SLR. For my LUMIX G9 it’s about 4 seconds. Go figger, but 4 sec is long enuf for any “long moment” that happens before my eyes.

——————————————————

Although a G9 can run much longer bursts if one tolerates a 10% drop in MPs, I tend to do 4 sec cuz I play bass so I’m good at counting to 4 !!!

My most practical use of that speed is to shoot just 15 frames which is about as fast as I can get my finger off the button.

However ! The G9 also records the 30 frames of action that occurred BEFORE I pressed the button so thaz already a 45 frame burst gone into the buffer just from a 1/4 sec of finger-on-button. There’s a pair of Sandisk Extreme 128s inside and I did NOT consult the manual ... I consulted the sale pricing on the card display at BestBuy ;-)

There is a manual for every thing. Go on line

I like to buy a SD card for my Panasonic G9 to shoot birds and sports at the highest burst speed. Do I need a Sandisk Extreme Pro UHSII 170 MB/s or 300 MB/s? Would appreciates comments from anyone who has experience in this.

You missed my feeble attempt at some semblance of humor.
