looking for some longer/somewhat faster glass

I'm checking out an SMC Pentax M 200mm f/4 lens, also I saw a 150 f/3.5 SMC M lens -
basically I'm looking to get some used glass to use for sports, and possibly some macro work with some extension tubes. Anyone have thoughts on these, or suggestions otherwise?

Really the only thing I have right now is the 50-200 kit lens, and it has autofocus issues, so I'm manually focusing everything anyhow, I'd like a slightly brighter view, but at the moment I don't have a ton of cash. I'm really just looking for ideas, I mull over this crap for weeks before I actually buy anything - it's a really annoying habit of mine.

Thanks in advance.

Try the M135 f3.5. You can get it for around $50.

can yoou define fast?

there are a lot of good options, depending on speed etc.

if 200mm F4 is roughly what you are looking at, There is a photo store in toronto that has 4 of them, 3 SMC-M200 F4 and one SMC 200 F4 (slightly bigger and heavier)


have you considered something like a vivitar Series 1 70-210. there are several versions including a constant apature f3.5 the extra 1/2 stop is a 50% increase in shutter speed (good for sports) and the lens can do 1:2.2 macro.

they show up occasionally in the forum. the single ring zooms are thebest in my opinion. They have a 180 degree rotation min to max focus so it is relitively quick, yet precise, and it is a true zoom so pulling back on the collar zooms the lens while retaining focus. Again a single ring zoom is better for sports because all adjustments are with one hand.

not very fast, but i bet the new sigma 150-500 would be pretty rad for sports

I used to have the M150/3.5 lens, kind of regretting selling it to fund other lens purchase. I have also got the M200/4. Both lenses are excellent for the money they cost. Here is some images I have got online, taken with M150/3.5:

@ Kenny - wow those are some crisp images. That gives a good + to that possibility.

Lowell: define fast: well, faster than f5.6 at the long end - f4 or better would be great. I'm leaning toward primes simply to focus on optical quality, but I've never heard a bad word about the series 1 lenses.

(MJB: If I had money for the Sigma 150-500 I'd rather just buy the Tamron 70-200 f2.8 instead...)

JMS: there's a Takumar 135 f/2.5 as well, that seems like it would be pretty sweet - but I've read there's two versions of that, and one has no coating, or very little, so I assume I'd have to be careful there.

The 200 f/4 is something I'm looking into, or the slightly faster 150 f/3.5. I need to go around with the zoom set at those focal lengths and try a few quick shots tomorrow and see what would be best for what I'm planning.

I just saw a vivitar 75-205 f/3.8, but it's not a Series 1 - Like I said, I'm mulling over things. Looking at my favorite used places online, there's the 150 f/3.5 for $115, a 200mm f/4 for $99, a Takumar 135 f/2.8 for $89, then if I wanted to spend some money there's a 300 f/4 for $299.

*grumble* 3 weeks from now my wife will say "did you buy a lens yet, you're driving me crazy?"
I have a little bit of money stashed away, and I may be able to afford a bit more than what I've been looking at, but I've never owned anything faster than f/5.6 in any focal length longer than 100mm, and unfortunately my purchases must be made online without any handling of such a lens, because there's no place around that sells used Pentax stuff nearby. So any other suggestions are totally welcome.

for the sports shooting, i thank the A*200/2.8 or A*300/4 may be good choice. because if you want "fast" the F2.8 would be very usefull. these two lens also easy to find(about 800$?)

(Kenny - very nice shots)

Dan, The M 200 f4 is a great little lens, not particularly fast, but sharp, light, well made, great bokeh. Here are a couple examples:

I use a Sigma 70-200/2.8, usually with a Sigma 1.4x on, unless it get too dark.
I am happy.
Though I am looking forward to trying the latest HSM version.
If you get a second hand, or even new, Sigma like this go sor it, it's great. The lens with the 1.4x means you either have a 70-200/2.8 or ~100-280/4. The HSM should be at least as fast to focus as the Pentax 60-250/4.

If it wasn't for budget constraints, one of the 2.8 zooms is how I would go - for now I have a limited budget, plus I want to keep the weight down.
I think I'm leaning toward the SMC M 150 f/3.5. I'll post my experience with it once it arrives. Thanks everyone for the suggestions.
