if you're doing this with a camera, you need a consistent light source as well. which that adapter from JJC seems to have its own light source. otherwise something in the mold of a Huion L4S light pad, will make post at least a step easier.

having said that, there's no getting around having to shoot each frame, and that's a bit more cumbersome than you can anticipate. how many of them are you looking to digitise? you will also need a photo editor - lightroom does a good job, the worst ones i have required a trip to photoshop.

i first did this some 20 years ago with a Coolpix 4500 + ES-28 slide copier, and came away happy with the pretty good results. a modern dslr/mirrorless would definitely do a better job. what you won't get is digital ICE, which depending on the condition of your film, would help A LOT. and that is a big factor in how much time you spend per frame.

i'm currently in the midst of the same. 🙂 where are you based? if you can trust me with one of your priceless (like i consider my ones) film strips, i can give one a run to give you an idea of what they'd be like out of a coolscan v. it takes me ~15 min per frame scanned to raw then converted, but much longer for the ones in poor state. the people i've shared my output with have all told me to turn this currently hobby into a side hustle, but i'm not done with the family stuff yet - some from 50-year-old strips.

ah, you're in akl...
