>If your 4x5s are barely beating your D3300, that's on you. Only the higher end medium format digital really matches 4x5 in terms of resolution

These two statements contradict each other. There is not much difference in resolution between 24MP and 50MP (4.9 : 7), so if I was getting ~50MP of resolution in my 4x5 negatives, you wouldn't expect to see a big difference, even if I was doing everything right.

>Moreover, if you do a 'DSLR' scan of the negative, you can get quite a bit more detail.

This is in fact what I do (using a very sharp pre-AI 55mm Micro Nikkor). I do get benefits from stitching multiple 24MP "scans", but this is because there is always some resolution loss in scanning. So, sure, I might end up with a 100MP file, but I find that I can typically reduce that down to around 30-40MP without losing any detail.

Do you have an example of a 100MP scan of a 4x5 negative that loses detail when reduced to, say, 50MP?
