I have seen posting mistakes before, and this smells like one (not from our poster here, but from the lens seller). I have seen a 50mm f1.2, but when you look at the images of the lens (always get these, the fron of the lens stated 1:2, so it was an f2 50mm lens. I will bet hard money this is a 20mm f4. Get pictures.

Sorry to post again and again...

I just shot a sample.
Sorry for the bad photo.
I am a Nikon Z7 user and do not have a Pentax camera. This lens is hardly used.
The aperture I can use is only 1.4 due to poor mount adapter.Lens has no problem(Apature works).
If you want to see more samples,I will take tomorrow.

You can use the lens aperture ring to adjust the aperture

Yes, but you still need a K-mount adapter with a stop down mechanism to operate the diaphragm lever

The close focus sample looks great. That's probably where I would use it most

. The standard mode of an K or M lens is stopped down, unless something is pushing the aperture lever. So you need an adapter that doesn't push to lever. That way the aperture will respond to the ring immediately.

OMG wow, this is amazing! I would love to own a lens, or even just see pictures taken with it. On the other hand, I would almost be too scared to take it out of the house.

How much are these going for on ebay these days...

I can't believe this hasn't gained more traction - it's a part of Pentax history that's been myth for so long.

Awesome post Japanese guy! It sure made my day and other guys here in the forum. Keep posting sample pictures!

SSGGeezer · 01-07-2020, 03:14 PM

The lens looks immaculate! A true Pentax Unicorn!

**Pål Jensen** · 01-07-2020, 03:14 PM

Anyone with the M and/or the A 35/1.4? They are just as real as the 24/1.4
