I shoot film, 35mm, and am looking to get some more lenses. I have two already, 36mm and a 50mm, both fixed focal length. I want something longer, so I can shoot some stuff from further away, and I found two lenses that seemed good:

1) pros: cheaper, goes down to f2.8
cons: fixed focal length, 135mm
2) pros: zoom, 80-200
cons: more expensive, f4.5
I understand aperture size a little bit....it relates to the length of the lense somewhat, somehow. I've never bothere dot learn more than that, I just know how to expose an image well, it's never mattered to know aperature width, just the fstop. So, will the f4.5 on the zoom lense keep me from shooting indoors without a flash? What I've got now goes down to about 2.8 (something like that, it's been a while since I've shot anything, my camera broke, and I'm too lazy to go pull out all my stuff to get real numbers) and it's been adequate. The advantage of the zoom is that I could use it in multiple situations, but if I can't shoot in indoor conditions without a flash, there is no point to it being short enough to use inside. The other lense is cheaper, and I think I could use it inside easily enough, but it is fixed, and I've been wishing to get a zoom lense for a while now
And yes, both are manual focus. Myc amera body is manual focus only, so it doesn't matter if it's AF, and I don't plan on getting any pentax AF bodies anytime soon
