Optimized for corner mounting, this 2-pack of matte black Vicoustic Super Bass Extreme Ultra VMT Bass Trap features a beige front, and it is designed to provide effective low-frequency absorption between 60 to 125 Hz, delivering maximum effectiveness between 75 to 100 Hz. The VMT front provides sufficient mid-high frequency absorption to control corner reflections. When porous materials such as foam are applied to corners or walls, they become less efficient in dealing with low frequencies, because the particle velocity or air movement associated with long wavelengths is low. However, the sound pressure is at its maximum and Super Bass Extreme's internal membrane transforms these high-pressure fluctuations into air motion. The membrane sympathetically vibrates over a 75 to 100 Hz frequency range, causing the air to pass through a layer of high-density foam that absorbs the low frequencies. Super Bass Extreme Ultra is highly recommended for smaller rooms with low-frequency issues. The panel can be used in different corner positions, and its modular structure allows further units to be added as required.

Q: 1. Is this the correct card for the 1Dx MkIII? Am I right that it has 2x identical slots for the same type of card?

A: Yes, the SanDisk 64GB Extreme PRO CFexpress Card Type B is compatible in both memory card ports in the Canon 1Dx Mark III.

Q: 2. It only says it can record raw 4k video. Will it work with 8k 60p raw and 4k 120p in the upcoming canon r5 mark ii?

A: Yes, the SanDisk 512GB Extreme PRO CFexpress Card Type B can also record 8K 60P RAW and 4K 120P video with the Canon EOS R5 Mark II Mirrorless Camera.

Q: 3. It would work on an SLT-A58?

A: No. The Sony A58 needs an SD card like this https://bhpho.to/36MUPMm instead of a CFExpress card.

Q: 4. Will this card work for 600 Mb/s 4K/60 All-I footage from the Sony A7SIII?

A: No, it would not be compatible. The SanDisk 128GB Extreme PRO CFexpress Card Type B, B&H # SACFEP128GB, is a larger card that is not compatible for use with the smaller CFexpress Type A card slot found on the Sony Alpha a7S III Mirrorless Digital Camera. While we do not currently have a CFexpress Type A card from SanDisk, the two options we have that would be compatible would be the Sony 80GB CFexpress Type A TOUGH Memory Card, B&H # SOCEAG80, or the Sony 160GB CFexpress Type A TOUGH Memory Card, B&H # SOCEAG160. The maximum bitrate for the Sony Alpha a7S III is 600 Mbps, which would require a minimum sustained write speed of 75 MB/sec or faster to record 4K video. The Sony memory cards listed above have a minimum sustained write speed of 400 MB/sec, and would be more than fast enough for your usage needs. If you need a card that is currently in stock, as the Sony a7S III also supports SDXC UHS-II cards, the Lexar 128GB Professional 2000x UHS-II SDXC Memory Card with SD Card Reader, B&H # LESD2000128R, has a minimum sustained write speed of 90 MB/sec, and would also work for your needs until the CFexpress Type A cards are available for purchase.

Q: 5. Will this work with Canon C400 in 6K?

A: The SanDisk 512 GB Extreme PRO CFexpress Card Type B is not a VPG400-rated card. While it should work with all the recording modes of the C400, we recommend working with VPG400 media when it has a guaranteed minimum write speed of 400 MB/s, like the card listed below: SanDisk 640GB PRO-CINEMA CFexpress Type B Memory Card (B&H # SA640PCTBC)

Q: 6. Does this work for r6 cameras ?

A: CFExpress won't work on the R6. The R6 only accepts SD/SDHC/SDXC cards.

Q: 7. Will this work in the new Nikon Z6-iii?

Q: 8. Is this new or used?

A: Our products on our B&H website are always new unless they are from the used section. The SanDisk 512GB Extreme PRO CFexpress Card Type B is new.

Q: 9. Will these work with older cameras, specifically the Canon EOS Rebel XT?

A: No, the SanDisk 512GB Extreme PRO CFexpress Card Type B is not compatible with the Canon EOS Rebel XT. It won't fit.

Q: 10. Will this work with Canon R6M2 and Canon R& ?

A: The R6 II and the R7 cameras are compatible with SD memory cards only, so they are not compatible with the SanDisk 256GB Extreme PRO CFexpress Card Type B. The R6 II and the R7 are compatible with the SanDisk 256GB Extreme PRO UHS-II SDXC Memory Card. https://www.bhphotovideo.com/c/product/1617742-REG/sandisk_sdsdxdk_256g_ancin_256gb_extreme_pro_uhs_ii.html
