The scans from the lab are ok, but they are low res jpeg files that I think are even scanned a bit out of focus or with some softness applied.
Dedicated scanners typically have a very deep depth of field. The softness comes from the “dust-removal” software that they get run through afterwards.
Do a test run at a number of labs to see which suits you best.
So I'm going to buy this lens for my Canon M50 and build a scan setup. Thanks!
A DIY setup can be as simple or complex as you want. Do avoid the (numerous) pitfalls. And be prepared to spend copious amounts of time in post, even with good software (such as Silverfast).
Biggest tip: Get your negs/slides as DUST-FREE as possible! Avoid scratching!
Best of luck!

Thanks!
I got my lens today and did some test scans to compare with the scans from the lab. So far, I'm very happy! here's a test comparison, with some zoom:

Hopefully you're able to tell which one is which lol
Left is mine, right is the lab. In mine I see the grain is a lot "finer" and subtle, plus a lot better tonal range I think?
Very nice job! Yours is waaay better.
I scanned a few color ones and the result is not as good as the lab. Color needs a lot more post-processing and my DYI setup is lacking something to hold the negative flat on the light bed. Right not I have a cheap (but very bright) LED panel with cardboard cutout to block the light outside the frame of the image (poorly...) and my canon m50 on a tripod.
Color negs are tough. Here’s where you might want to try some commercial software (like Silverfast).
Get yourself a negative holder (about $20). Use a large depth of field (but don’t go into diffraction).
And yes, dust is your works enemy 🤣
👍
Have fun!
