The little blue 12V Bosch cordless drill you show is an excellent cabinet shop or light construction item made in Malaysia. I have their full set, including the impact and right angle drivers, which Bosch gave me for sake of an endorsement. But it's certainly not ideal for camera or other sensitive technical repair purposes.
What you need is an especially linear attachment rotation with minimal wooble, along with an especially sensitive clutch to avoid stripping small screws. Only the German Festool 12V system would provide that, which is significantly more expensive. Otherwise, you better stick to doing it by hand. The only exception, where a Bosch impact driver or drill might be suitable, would be to remove a stubborn screw in reverse mode, or else use it just to drive a screw most of the distance, and then do the final tightening by hand. That's how I've often used it in relation to camera or darkroom gear. An impact driver works much better in this respect than a drill.
Still, you need to be careful about bits themselves. It looks like you have indeed selected quality Japanese driver bits; but I am unfamiliar with that specific brand. When it comes to drill bits, I'd recommend domestic cobalt steel ones. Getting a good center hole into a small screw for sake of a tiny easy-out or screw extractor, is a demanding task. I only use my small Sioux industrial air drill for that kind of purpose, because it has almost no runout wobble at all (cheaper air drills are a different story, sadly). And again, it's hard to find good quality screw extractors unless you shop at a true industrial supplier like McMaster. Once a cheap one itself breaks off inside a screw, you're really in trouble.
Dremel tools? Everyone needs one of those sooner or later, unless you have a more serious die grinder system.
Want the finest in a tiny yet powerful cordless impact driver or drill. Try the Makita aerospace version. These are programmable to within 2 or 3 % preset torque value, and have flame and explosion-proof batteries for sake of combat conditions. I don't know their current price; it was about $8,000 apiece 15 years ago, or double that for one ergonomically adapted for space gloves. Every DIY home rocket ship shop needs one. Most of the ones in use in this area are at the Tesla/Space X plant.
