I want to purchase one of these two lens and was wondering if anyone has any personal experience and can make a recommendation?

Thanks,

The F3.5 is considered to be the bett of the two. I have both, and I thinks so too - very sharp!

My experience

About 4 years ago I was debating between these two lenses. My research of common opinion indicated that the f3.5 was sharper than than the f2.8 and had better contrast. So I bought it. I was happy with the lens and had no complaints, but when I later bought a FA 31 Ltd it became redundant so I sold it.

As I recall there are two versions of the M 28/f2.8 with different reputations.

I didn't have a chance to play with 28/2.8, but 28/3.5 is an incredible lens with outstanding sharpness and contrast.

IMO the K28/3.5 is one of the very best ever made.

Cheers.

I owned M28/2.8, then A28/2.8 and sold both. Not bad lenses at all but with strong back light both are prone to flare and producing low contrast. Also, at f/2.8 corners are a bit soft and vignetting is noticeable (but not bad).

I have M28/3.5 now and it's here to stay: better than M28/2.8 in terms of flare resistance, contrast, color rendering, and corner to corner sharpness, but at the expense of loosing 1/2 steps which is acceptable to me.

So get one, you won't regret.

It exist two versions of the M 28 f/2.8, the Mk II was sharper than Mk I.

What I like about them is that they have a warmish tone to the images. I have also owned the FA 28 f/2.8, which in many ways was a better lens - technically speaking - but I liked the images from M 28 f/2.8 more... It simply had flair. (no, not flare Flare was never a problem).

The K version is better corrected than the other 28mm lenses for chromatic aberrations and the like. I don't think it is any sharper in every day situations, but it certainly is an outstanding lens.

The first version is much more common. The second version is optically identical to the Pentax-A and Pentax-F, and has some physical features of the A lenses. (It won't work like an A lens, though.) The easy way to spot a Pentax-M version II is the serial number is not on the front of the lens; it's stamped near the aperture ring. It will say only this around the front element:

Is this the sort of bokeh you usually get from this lens in the dreaded branches in background situation?

Thanks to everyone...

...for the feedback. I have been looking for a K 28mm/3.5 with no success so it looks like I will jump on the M 28mm/3.5.

Cheers

Yes - the bokeh isn't what you'd call 'dreamy' in that situation.

But I like it - I love seeing different types of bokeh. Each lens has it's flavor.

I loved my M 28 f/2.8 - sold it because I have the Vivitar (Komine) 28 2.8 Close Focus, and a mes of 35's.

According to Bojidar's site M 28/2.8 Mk II is the same optically as A and F 28/2.8 so technically I owned both (since I had M Mk I and A which is the same as M Mk II) and Mk II optics was indeed sharper to my eyes. Here is the story:

I think so; not that different from the f/3.5 version, based on shots I've seen.
