The Panasonic GH7 has a dual memory card slot that accepts both a CFexpress Type-B card and an SD UHS-II card.

You will need CFexpress cards for this camera to use all the best video features.

Recommended CFExpress Memory Cards Panasonic GH7

The Panasonic GH7 can shoot ProRes RAW at 5728×3024 50fps at up to 4.2Gb/s, or around 650MB/s. This will require high-end cards with very good sustain speeds.

After testing the cards with the camera, here are a few recommendations.

When I tested the CFexpress Type-B card the camera essentially had a bottomless buffer when it came to bursting photos, so I wasn’t really able to get a benchmark with CFexpress Type-B card.

Recommended SD Cards Panasonic GH7

For shooting at lower bitrates you can save a lot of money by using V60 SD memory cards. V90 cards are no longer as good of a value as CFexpress cards, so I recommend v60 for these lower bitrates since they will let you shoot at bitrates up to 480Mbps. This is great for H.264 or H.265 video formats.

However, you can also write to both cards simultaneously, so if you are shooting at higher bit rate, you would need a v90 card to handle that.

Here are some recommendations.

Panasonic GH7 Memory Card Speed Test

Benchmarks with the CFexpress Type-B memory cards just show a bottomless buffer, but these benchmarks can be useful when looking at SD memory cards. However, SD memory cards are more prone to damage or may not always run at the appropriate speeds. Something as simple as dirty pins can throw results off. I try to clean my cards and keep them in good shape, but every so often I get a bad connection from either a bad card or poor connection.

Here are the results.
