With the lens in my hands, off of a camera, nothing happens when the shutter is cocked. The iris stays open. However, the shutter is tripped by moving the black lever on the back of the lens, it is a part that fits inside the camera mount and is tripped when the trigger is pushed. It closes the iris. The cable release does not do it. The U/S switch is on U. Use the switch on the side of the lens and set it to Manual to make the shutter move.
Thanks for the video. When I'm using this lens as just a walk around without a flash. Seems the only way I can adjust the f-stop is by moving the lens switch from Auto to Manual. Is that normal? In Auto, the lens seems wide open and adjusting the f-stop does nothing
I'd do some landscapes and portraits. It'll reduce 'shake' and speed up synchro time woth flash. I think, I won't see any difference between B and B+ :) thank You for fast respond
Hi! Thank you so much for making this video! I just bought the 90mm 2.8 leaf and tried to test it using your tip (12:40) and it seems like my lens won't fire yours. I cocked the the lens, pressed the tiny button at the back slowly but the lens won't fire. I can only hear a rewinding noise. Do you think it's broken?
What flash syync cable did you use? Im having trouble with mine as the cable works easily on the body but when in the lense it doesnt however when the metal touches the metal it does
Good video. I received a near mint copy of this lens from Japan. There is a slight rattle when I rotate the lens. Does yours do that? If so, do you know if it is a spring mechanism for cocking the lens? I ordered the 67 body and the lens at the same time. The lens arrived and I'm still waiting on the body. I am hoping the rattle is normal. I will review this video again when the body arrives.
I shot three rolls of film with this lens that were all completely un-exposed. Apparently, the shutter lens was closing and blocking the image every time I snapped a picture. I still don't understand what lens setting I had that caused this extremely unhappy outcome.
I think you should note that the 2x converter is not designed for optimal performance on non-telephoto lenses, so its use on the 90mm lens is a significant compromise in image quality.
Well, there is only one LS lens listed: antiquecameras.net/pentax6x7lenses.html And the specs say yes the newer lens is sharper, but no Leaf Shutter, so, what's the use?
The 90mm 2.8 NOT LS, is a newer design and is optically better, but the 90mm LS is not a dog. If you have the 90mm 2.8 LS, I'd keep it. If you are looking for a 90mm, buy the non-LS as the LS version shutter cannot be repaired any more [no parts]. If you need a leaf shutter lens, buy the 165mm 4.0.

Thanks so much for the video! You answered my questions so concisely and quickly.
I notice you have it set for 220 film. Was 220 still available 6 years ago? Wish it was available today.

Great information.

It electronically stops down when the shot is taken
@@MichaelCarter So I can just keep it in Auto and I'm good to go? Thanks for your help Michael.

I had sent my lens away and found out a slower shutter speed was required.
What flash syync cable did you use?

An old one from ebay that plugged into the strange button on the camera
@@MichaelCarter strange button?
@@fstisted it has a proper name which I forgot. A picture of the camera parts in a manual was used to identify it, then it was bought.

The 165 LS has a slight noise, but the 90 LS is quiet. .??? I hope it works for you.

I would use the camera and lens with the back open without film and shoot some to see if light can be seen or even lock the lens and iris open.

Thanks for that.
Hi, I heard that this LS 90mm is not so sharp as the SMC 90mm from 90's. What is Your opinion?
Well, there is only one LS lens listed: antiquecameras.net/pentax6x7lenses.html
And the specs say yes the newer lens is sharper, but no Leaf Shutter, so, what's the use?

Do not neglect to set the U/S lever to U, or complete exposure will not be made.
