I own both lenses and the image tests I have done seem to bear this out. If you want a 28 for landscapes, shooting stopped down, the M28 2.8 would be a good choice.

I've also noticed that from the chart, maybe f3.5 versions (K/M) have better contrast or something that make them stand out in IQ compared to f2.8 versions

Someone who used both frequently can comment. My 28/f3.5 in shipping so I can compare once I receive it.

I love the M28/2.0. It's my best M series lens. Also, my copy of the F 28/2.8 does not seem to exhibit the PF issues mentioned by others. It's capable of doing excellent work, as well.

Cheers... M

Does anyone have any experience with the A 28/2? I have one that I picked up but hardly ever have used.

I have no experience with it, but it seems to be very well liked judging from the lens database: https://www.pentaxforums.com/lensreviews/SMC-Pentax-A-28mm-F2-Lens.html
