Don't Fart on A Camera: Pentax-M SMC 28mm F-2.8 Lens

So I was out taking some photos of the Tower Bridge one night, and my 50mm wasn't cutting it. I could only get like 3/4s of the bridge in the shot. So I decided it was time I got a dedicated 28mm lens. In my hasty resolve to acquire this new lens I bought the Pentax-M 28mm f-2.8. After using it for around a week, actually at like 3 days, I had decided that the sharpness of the lens would not work for me.So I put it on the shelf for a while.
I've been using it on my Pentax *ist DL and just using it for close up work and surprisingly it does fine for that sort of thing, the building shots that I took with it about a month ago, were totally unimpressive and that is when I kinda just decided that it wasn't what I wanted. I also noticed a lot of chromatic Abberation, so minus a few more points there.

I began using the lens with a Light Ring that is still a work in progress and it does fairly well for that sort of thing. The subjects aren't that far away and it doesn't degrade the detail. I took some cat pictures this morning with the *ist DL, and they came out pretty decent, acceptable at least.

My opinion of this lens is that it SUCKS for building or landscape shots, especially concerning anything with a large amount of detail. Close up is this lens main fulfillment in life.

These are some building shots I took with the 28mm, they are pretty decent but the detail is shitty. the close ups of myself and the cats are like I said more than acceptalbe. Comparatively to say the SMC 50 DA f1.8 or even the *ist DL kit lens.
