M100/2.8 vs M100/4 Macro

How does these two lenses compare for non-macro work?

M100/2.8 (non-macro) vs M100/4 Macro

I own 100/4. It's amazingly sharp and produces beautiful portrais however my only only grip with it is that split focus screen often blacks out at f4 which does not happen at f2.8 and was wondering if it's worth replacing?

Thanks
Yusuf

Our users think highly of the M 100mm F2.8, but I haven't seen any direct comparisons.

I believe you can't go wrong with M 100/2.8 -even for macro works
It's now my most used macro lens (for more magnification I coupled it with macro diopters and/or macro-teleconverter), portrait lens, and even landscaping short tele lens.
It's very sharp, very strong contrast, beautiful bokeh, and renders stunning full Pentax' tone.

Yes, the M100/2.8 (or A, which I have) is good for "macro-type" shots, as minahasa has well demonstrated. When I first got mine I was surprised that I could often get as close as I needed for flower shots, even though it's nowhere near a true macro. And as he also said, the images are beautiful - of a quality similar to Ltd and * glass, but only a little slower and much cheaper.

I have the M 100/2.8 and have often wondered how an f/4 macro version would compare, but I'm not willing to lose that extra stop and I too have a split screen which would darken at f/4. For most things my M100 looses out to the M85, mostly because of the focal length and that the M85 is superb, while the M100 is merely very, very good.

I tend to take the M100 to events like weddings as it provides good reach in a small package and is sharper wide open than the 85.

If you want a 100mm macro lens from Pentax that's faster than f/4, you'll need to go for A series or later, which will cost a lot more and be harder to find.
