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?
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.
And yes, dust is your works enemy 🤣
Very interesting! Good result.
I have a lot of my Dad's old Kodachrome slides. I transferred about 10 boxes of slides so far. I used the M6 mark ii and Canon EF-S 55-250 IS STM with an extension tube, in a dark room the slides about 3-4 feet away from the lens, behind the slides was a piece of white paper lit by 2 3000k LED work lights.
This worked very well for me --- as I could use my standard workflow using DxO Photolab to process the results quickly. DxO excels at white balancing, adjusting colors and tones, contrast --- but it's best attribute is its ability to sharpen and de-noise. I was able to bring the grain to the level where you just see a hint of it.
I have tried quite a few film scanners and like you found them FAR too slow to make doing more than just a handful of slides or negatives very painful.
I just got the EF-M 28mm macro a month ago --- based on your results I am going to try that next! I think I will try putting a bunch of empty filter rings, and then some 'step-up' rings (I have a full set stepping up from 49mm to 82mm with many rings) to see if 35mm slides will 'fit' in one of the rings.... I'll try to make a make-shift slide adapter at the right distance to fill the frame with a slide.
I'll report back how it goes.
Here's a sample from my 55-250 work... a slide of me holding a kitten at the age of 8! The film was badly faded but I was able to get some color out of it. It might not have even been done with DxO.... at any rate my post-processing skills are far better now and I'm sure I could do much better with the latest DxO PL!
