R5 Mark II Playback bug (2nd last image)

[noms78]

This bug likely appears under other settings too, but these are the ones I typically used when testing several R5 Mark II bodies at my local camera store in recent months. A factory reset did not resolve it.

Settings:

• Image quality: RAW

• Drive mode: Single shot
• Image review: Off (2nd-last Shoot menu)
• Card inserted (e.g., SD)

Procedure:

1. Take two photos.

2. Press Playback.

3. Press the Info button to check the sequence number.

Expected (no bug):

• Last frame shows as the final number (e.g., 2/2, 3/3, etc.)

Bug present:

• Playback shows the 2nd-last image instead of the last frame

Serial numbers with playback bug:

• 146 202 1 01 XXX
• 149 502 3 00 053 (1.0.2)
• 149 502 3 00 160 (1.0.2 -> 1.1.1) - bug persists
• 154 502 4 00 368 (1.0.3)
• 154 502 4 00 382 (1.0.3)

Serial numbers without playback bug:

• 149 502 3 00 534 (1.0.2)

• 151 502 3 00 043 (1.0.3)

I also posted about this bug in several reddit forums, for example:

There is no playback bug! The issue was caused by using older, slow SDHC cards (30MB/s) instead of SDXC/CFB.
