ngl i've been trying to chase that perfect sunrise at machu picchu and guess what? the latest a7iv firmware just dumped a massive stm32f7 update that wipes my custom intervalometer settings rn

the hype about "smart auto‑focus" is just an excuse for manufacturers to ship bloated i2c drivers that break my esp32‑c3 trigger board

here's the broken loop i keep hitting:

• push new firmware via sd card
• device re‑enumerates as mass storage
• bootloader resets to stock wiping custom dma buffers
• i spend hours reflashing the stm32f7 with open‑ocd just to get my 10‑second timelapse back

and the community forums keep saying "just wait for the next patch" like we have time when the sun's already set

i'm exhausted the only thing i trust now is a good old analog timer lol

anyone else stuck in this endless cycle of firmware hype vs real world shooting any hacks that actually survive a vendor's "improved" release would be appreciated

so i was on the rim of machu picchu at 2400m rn, sun just peeking, and my a7iv decided to turn every sky pixel into a white blob lol

• set exposure comp to -0.7 or -1.0, but remember the built‑in 5‑stop ND on the kit lens is a myth, bring a real ND8
• use spot metering on the summit silhouette, not center‑weighted, otherwise you get that overexposed sky vibe
• lock focus on the foreground rock, then switch to manual focus to avoid hunting when the light changes fast
• shoot RAW + JPEG, because the JPEG will be a hot mess but at least you can see the histogram on the fly
• bracketing 3‑shot ev 0, +1, -1 with 1/125s gives you a safety net if the sky decides to go full white

tbh the biggest mistake i see is forgetting to set the camera to ISO 100 on a sunny summit, i’ve definetly burnt my D850 on an alps sunrise before. bring a spare UHS‑II card, the buffer fills up faster than you think when you crank the burst mode for those epic wide‑angle panoramas.

any other summit‑sunrise hacks? drop your go‑to settings below
