Panasonic SD Memory Card Compatibility

The Panasonic G1 has an memory card slot that is compatible with SD memory cards. cards with a max capacity of 32GB are compatible with the G1.

Using an SD card that has a capacity of 64GB or larger will cause the Panasonic G1 to display an error code. You will have to buy more SD cards if you want increased storage. The transfer speeds of memory cards are the most important specs to pay attention to.

Faster transfer speeds will greatly reduce the time necessary to copy photos, especially if your camera will get frequently used. A feature that is nice to have is UHS-I as it allows for fast speeds with a compatible memory card reader.

Getting a high-quality memory card also helps to future proof the SD card for use in another device. This will help prevent a situation where you can not use a feature on a device or camera, such as recording 4k video, because the memory card's write speed is too slow.

This is my recommendation for the best memory card for the Panasonic G1:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB

  • Best SD card available
  • Largest compatible storage capacity.
  • Read speeds of up to 95MB/s.
  • Write speeds of up to 90MB/s.
  • Shock-proof, temperature-proof, waterproof, and x-ray proof.

Best SD Cards

Since the release of the Panasonic G1, SD card prices have fallen and capacities have gotten larger. The price difference between the the SD card that is the fastest and a cheap one is astonishingly little. Cost is more closely related to storage, with the bigger cards having a higher price.

Getting the cards with the largest capacity is worth it if you are going to shoot a large amount of RAW files for action, events, wildlife, or sports photography. Another reason could be if you are planning to upgrade your camera or use the SD memory card in a different device.

I believe that the SanDisk Extreme Pro line of memory cards are frequently the best choice for most cameras. They are very fast cards which means they have the best prospect of working in future digital cameras or devices that also use SD memory cards.

I have also had excellent experiences with Lexar Professional and PNY Elite Performance cards. I have not had pictures or data become damaged or lost on these brands. If that scenario did happen, all of them have image recovery software available.

Troubles I have experienced have been with generic SD memory cards. Having a low price or being a bundled accessory are the selling points of these cards. Unfortunately, this is also the most common type of card to have the wrong product description.

It is easy to put a Class 10 sticker on a card with a Class 4 rating. When the camera image processor starts writing data there is destined to be an error or corrupted photos if the card's write speed is not good enough.

Storage capacity controls a large portion of the cost. You'll be better off by going one step down in capacity to reduce cost as opposed to going with a relabeled brand. Read and write speeds are important factors that will influence your satisfaction with the Panasonic G1.

Recommended SD Cards

Lexar 633x 23GB UHS-I SDHC Memory Card

Lexar Professional 633X 32GB

  • High-speed, Class 10 performance.
  • UHS-I technology for a read transfer speeds up to 633x (95MB/s).
  • High-speed file transfer from card to computer to dramatically accelerate workflow.

The Lexar Professional is close in performance to the SanDisk Extreme Pro card when used in the Panasonic G1. The key difference is that the Lexar card features a slower write speed.

Sometimes there can be a big difference in cost between the Lexar and SanDisk memory cards. I wouldn't spend more for the Lexar, but also would not have a issue picking it if it was less expensive.

SanDisk Ultra UHS-I SDHC Memory Card

SanDisk Ultra 32GB

  • Good value to save some money.
  • Quick transfer read up to 80MB/s.
  • Class 10 rating for Full HD video (1080p).
  • Waterproof, temperature proof, X-ray Proof, magnet-Proof, and shockproof.

The SanDisk Ultra is a step down from the Extreme Pro in terms of specificatos. The benefit being that it costs less.

You will not start seeing a difference in time savings unless you need to write data that will fill up a large part of the memory card's space. This isn't the best pick if you plan to use the memory card to shoot 4k video one day.

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB

  • Read speeds of up to 95MB/s; write speeds of up to 90MB/s.
  • Shock-proof, temperature-proof, waterproof, and x-ray proof.

Memory Card Reader

UGreen 4-in-1 Card Reader
There's a bright blue LED that bothered me. It is now covered in gaff tape.

The UGreen 4-in-1 memory card reader supports four types of memory cards. These cover all memory cart formats camera manufacturers make use of in all but their most recent professional-level cameras.

The UGREEN memory card reader has a USB 3.0 connection. The card reader's USB 3.0 transfer speeds will be faster transfer rates than what the Panasonic G1 is capable of in USB transfer mode.

There are many favorable customer reviews for the reader, which I agree with. I would recommend it because it has worked with all the computers (Windows, Mac, and Linux) I have tried it with.

The cable prevents memory card slots from interfering with other devices or accessories that are plugged into another USB or neighboring port.

When I searched for a more compact card reader that would be lighter for travel, I needed to send a couple of orders back. I encountered the most commonly seen problem in customer reviews, the readers did not work with my computer.

The card reader supports the cards below:

  • CompactFlash Cards
  • SD, SDHC, & SDXC Cards (UHS-I supported)
  • Memory Stick (MS), MS Pro, MS PRO-HG, & MS XC DUO
  • MicroSD, Micro SDHC, & Micro SDXC Cards

Panasonic G1 SD Card Compatibility

Only use SD and SDHC memory cards with the Panasonic G1. Check to make sure that your camera has the most recent firmware.

SDXC or SDUC cards are not able to be used with the G1.

You should be aware of the 4 different types of Secure Digital (SD) memory cards that can be found. They are divided by capacity.

  • Secure Digital (SD) - 128MB to 2GB.
  • Secure Digital High Capacity (SDHC) - 4GB to 32GB.
  • Secure Digital eXtended Capacity (SDXC) - 64GB to 2TB.
  • Secure Digital Ultra Capacity (SDUC) - 4TB to 128TB.

Image Capacity

Image quality settings on the Panasonic G1 will affect how many pictures you can store at once. Higher image quality settings will result in bigger image sizes.

If you are intending to shoot a large number of RAW files, getting a larger storage capacity card can make sense.

If you shoot JPEGs, you would likely be better off purchasing another camera battery rather than a bigger SD card. 32GB should be enough space to save a few days of photos.

The limiting factor to the number of images you can take will likely be your camera batteries. Remember that, any time the Panasonic G1 is turned on, even if you're just navigating through menu options or using the live view, that will reduce the battery life.

For low light situations, like indoors or at night, the flash built-in to the camera can be useful. Shutter speeds will not be fast enough without using the flash to avoid motion blur. Working with the built-in flash is going to rapidly drain the camera batteries. These conditions are when it is good to own at the very least two Panasonic FZ-G1 rechargeable batteries.

The following is an estimation of how many high-quality JPG images you will be able to save on a memory card for the provided capacity:

  • 4GB - 1,160 images
  • 8GB - 2,320 images
  • 16GB - 4,640 images
  • 32GB - 9,280 images

Speed, Class, & UHS Ratings

Card Speed

Speed ratings of an SD memory card is determined by the sequential write and read speeds. Card continuous write speed is essential for continuous shooting in addition to video.

Slows SD cards can cause a drop in the number of continuous images the Panasonic G1 can take. This is because the camera's buffer will not be able to write data to the memory card fast enough.

With video, a slow SD card can cause recording to stop. The video file may also end up being corrupted. If you are going to shoot video, it is crucial the SD card you use meets the requirements of the camera.

Read speed is nice to have for file transfers to a computer. If you have cards that are full, a memory card with a fast read speed will save you time.

Speed Class Rating

Example of where to find SD Card Speed Class
The 10 inside of the C means the card is Class 10.

The Class rating of a memory card is determined by the sustained write speed. Memory cards that have a minimum write speed of at least 10MB/s will be rated Class 10.

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s or faster

Every brand name SD card that you can get online will be rated Class 10. To find the class rating of a card, look for a number inside of a C on the label.

Ultra High Speed (UHS)

Example of an SD memory card with a UHS-I rating.
The UHS rating of a card can be determined by a Roman numeral I, II, or III on the label of the card.

The Ultra High Speed (UHS) bus can be found in SDHC, SDXC, and SDUC cards. The UHS bus cards to achieve faster transfer rates.

There are 3 different specifications. They are UHS-I, UHS-II, and UHS-III.

You can find out the UHS rating of a card by examining the front of the memory card. If the card has UHS, a Roman numeral I, II, or III can be seen on the front of the SD card.

  • UHS-I - Maximum transfer rate of 104 MB/s
  • UHS-II - Maximum transfer rate of 312 MB/s
  • UHS-III - Maximum transfer rate of 624 MB/s
