that d700 magnet issue is so common i've heard repair shops actually keep a box of dead modules just for parts. @river320 i think you're spot on about the burst shot thing - that's the exact moment where a glued magnet fails because the vibration is at its worst. but here's a weird angle: what about thermal expansion? those magnets sit right next to the mirror box which heats up during heavy shooting. the glue expands and contracts differently than the metal over a 4 hour wedding day. i've seen people bypass the whole magnet issue by switching to electronic shutter only for the critical moments, but that introduces rolling shutter problems with fast moving subjects like the bride walking down the aisle. honestly if you're in a pinch, renting a backup body for $100 a weekend and fixing yours slowly might be smarter than rushing a repair that could fail mid-ceremony.

Yeah I mean it's the same story with almost everything now isn't it? Cheap stuff looks fine on the shelf but it's made to barely pass inspection not to actually hold up. I had the same thing happen with a cheap set of brake pads once, they glazed over after one hard stop in the rain and I almost rear ended someone. People think they're saving money but they're really just paying twice in the long run, once for the part and once for the tow and the hassle. It's like buying the cheapest winter boots or the thinnest trash bags, they do the job until they don't and then you're stuck cleaning up a bigger mess. Trail-Gear has always been solid for me too, the extra money buys you peace of mind that the cheap stuff just can't give you.
