Just Bought A Pentax Super-TaKumar 300mm F4.0 M42 screw mount

I used to own one many years ago and liked it a lot on my Pentax ME Super. I think you will like it. However the Pentax 300/4 is a bit of a beast and it does not have a tripod mount (depending on the version you got).

I currently have the Nikon 300/4.5 which I like and I just picked up the Pentax 300/6.3 so I can compare them. If I can give up an F stop the Pentax 300/6.3 is much smaller and lighter.

 

I'd be interested to hear how you like this lens, and maybe see some sample pictures, since I've been thinking of getting the same thing.

I recently bought a Nikkor 300/4.5 ED-IF, which was really nice, but I sold it to raise money for a Panasonic 100-300mm. The Nikkor's probably a better lens, but I'm going to need the flexibility of the zoom for some upcoming trips.

So anyway--I hope the 300 is working out well for you.

 

That's impressively sharp for hand-held and low light.

 

Those look really good.
