The 2.8 is smaller. Which is weird cuz normally faster lenses are bigger. Apparently the 3.5 is better, but I have been very happy with my $20 like new 2.8!
I believe it’s the same in the OM system (28/f2.8 smaller than the 28/f3.5).
For Pentax the real gem for slower wides is the SMC-K 28/f3.5, with its fancy pants 8/7 design.
