HELP!!! i am using an r6m2 with an rf 50 1.8

while editing this session, i have noticed that at this specific location of the session, red and blue dots appear on the photo. this was shot in raw. there is red dot in his hair, a blue one above their heads and red and blue dots on the left hand side as well. this didnt happen at any other location during the shoot and has never happened before.

It is unclear whether it happened *after* this shot. If so, it is probably a sensor issue. If not, it is likely file corruption. Try a new card.

It may be due to the raw converter too. Mind sharing the raw file?

"is my lens cooked?"

No, very unlikely to be the lens. First culprit is the SD. Is the SD a top quality brand purchased from a known good retailer? Amazon and eBay are not known good sources. And exactly the SD recommend in your manual. Never a micro-SD, never, never.

Second question, is this on all your shots or simply this one? Do the color dots appear in your jpg shots? My last suggestion is to d/l and use DPP4 for all your raw conversions to your computer. DPP4 is the only converter/editor that knows Canon raw files 100%.
