any old manual 200/2.0 lenses?

I've been digging for something like this, but did Pentax ever make any old 200mm, f/2.0 lenses?
Saw some awesome bokeh out of Nikon's variant of this lens (Canon also makes one). Both are in the $3500 range

Hello,

AFAIK, the fastest 200mm made by Pentax was the Pentax-K 200/2.5 ... Only seen once from a seller on the auctions site, it seems that it was a really good performer ...

Hope this helps

Best regards

They also made a SMC Pentax A* 200mm F2.8 ED, which I would recommend you try if you can find one somewhere.

Pentax had a prototype 200mm f2. I don't think anyone has seen this in real production.

Olympus has 180mm and 250mm f2. They are excellent lenses and might be able to used on Pentax camera. They are extreme rare and very expensive.

You might get a hold of 135mm f1.8 or f2.3, or even extreme f1.5 from vivitar or other third parties. They act like 200mm on dslr. All of them are pretty soft wide open. Among them, Vivitar S1 f2.3 is better.

One sold this week on eBay for under $500. What a steal

I found my k 200/2.5 on b&h for 350. It's a great lens stopped down even a tad, but focuses kinda slow, even for a MF lens. keep your eyes peeled and you may see one for a good price.

As noted above the K 200m 2.5 was the fastest telephoto 200mm or larger to make the production line. Apparently Pentax showed a 300/2 prototype in the late '70s, but it never made it to the market place. Too bad but the price would have been astronomical. I came across this footnote while reading about the Nikon 300mm f2. Seems this one had a $29,000 price tag. A bit steep for me.

Nikon F 300/2

Cheers,

"compact Nikkor 300/2 ED-IF AIS weighs in at a petite 16 lbs"

Now that's a good one...I doubt the Pentax one would have been any cheaper or lighter unless they bent the rules of physics :-)

Kenyee, I have finally gotten an adapter for my 180/2.8 Sonnar, and it is said to be a bokeh champ, see Bokeh Test.

It's not f/2.0, but with tele lenses it does not matter too much if it's 2.8, cause the DOF is very thin in both cases. I have yet to test it at full open, said to be nearly as good at full open as closed down. See Mother of Lens Tests for build spread of this lens.

Downside of it, it's a medium format lens, and so the resolution is not quite up there with the 35mm film lenses. On the same token, you get a 2.8 lens that is huge (about 90mm diameter and quite heavy, with tripod mount on the lens), but there you have your bragging rights also :-)
