Filter to enhance the quality of image

Then the barrel distortion/color fringing can be corrected in the software (darktable, RawTherapee, etc...). Using a lens with a fixed focus (no zoom lens) greater than 100 mm is better. On the other hand, old photo prints mostly have barrel distortion/color fringing and in this case, it is about a flat object one is trying to digitise.

Hi,

Thanks for your advice.

RAW image is lossless, capturing uncompressed data from camera sensor.

My Samsung Galaxy S9+ smartphone is provided with RAW mode shooting.  I'll try it later shooting film negatives, both with and without scanning software to check the result.  I'll post my testing results here thereafter.

Would following lens be suitable for my use?
EF 100mm f/2.8 Macro USM

Does it fit to Canon EOS 850D Body ?

Or Canon EOS 4000D Body

Can I use this LENS for daily life shooting ?
