Nikkor Lens Adapted for use on Pentax K1 camera

[BruceSD]

When using the modified Nikon/Nikkor and Zeiss lenses on the K1, does one have to manually stop the lens down to the taking aperture?

I am unfamiliar with the Pentax bayonet and its K mount system and I cannot see from the Leitax photos on their web site as to whether the K1 can work the lens apertures of the converted lenses.  The changeover process does not seem to be too difficult and its is nice that it is reversible.

Thanks in anticipation.

When I shoot my K1 with my many adapted lenses, I use the aperture shooting mode.   Set that aperture on the lens' aperture ring.   The camera automatically selects the shutter speed.

I can only speak for myself. I had the K3 and the K1, both of which have the pixel-shift technology. There were two main reasons for my not keeping the Pentax K1,
pixel-shift technology on the K1 (while good as a proof-of-concept) was not ready for Prime Time. It only worked with no movement, which was OK with me, and even then there were all kinds of smears, blurs, etc. that muddied the waters. So, I applaud the concept of pixel-shifting, but not this iteration of it... IMO. Others will obviously disagree, but what's new?

In the pixel shift mode the K1's results are incredible!  Post the same photo from a Nikon D810 and a K1 in pixle shift mode, I would wager that most would prefer the rendering and incredible detail of the K1 image.

Certainly, motion does adversely affect pixel shift images.  If there is wind, just shoot a second photo in the "non-pixel shift" mode and blend the two using layers in post - walla, the movement artifacts disappear.   

Also, just like my friends who fly hot air balloons at dust and dawn when wind is at it's lowest velocity,  K1 pixel shift shooters also tend to shoot more at dust and dawn and other times when wind is less of a factor.

Pixel shift does involve a bit of extra work at the time of capture and during post processing.  I happen to be a photographer who believes that the incredible results achieved when using the K1's pixel shift makes the extra effort clearly justified.   

For the photographer like me who shoots landscapes and stuff that does not move very fast, the Pentax K1 in pixel shift mode is a viable option.

However, I do prefer to shoot my Nikon system for birds in fight, and super fast action sports. 

No one camera is optimum for all subjects and shooting conditions.  I use my Pentax K1 in pixel shift mode with adapted Zeiss "Classic" and "Milvus" lenses for stuff that doesn't move much that I want to print LARGE; I use my Nikon system for fast action; and I use my Fuji X system for snapshots and Internet images.

When I shoot my K1 with my many adapted lenses, I use the aperture shooting mode.   Set that aperture on the lens' aperture ring.   The camera automatically selects the shutter speed.

Ie. stop-down metering, or not? Does the aperture of the converted lenses stay fully open for focusing *and* metering ? This would be the return of the technology of the late '50s and early '60s. No appeal for me, plus of course a lot of lenses cannot be used when one cannot manually control their aperture. 'G' and 'E' Nikkors come tomind.

The lack of aperture linkage is hardly Pentax' fault, to be fair; just a reminder that one uses lenses not native to the actual system. When there are so many specialist lenses in one system and none in another, the inducement to "switch" is curtailed.
