Q-S1 w/Pentax 16/1.4 C-mount TV lens shot wide open. Lens sharpens up nicely when stopped down.

Pentax Q-S1 w/Pentax 16/1.4 C-mount TV lens shot at f/4. Unfortunately I forgot to check my settings and all shots were at iso 1000. This lens is remarkably free from CA/purple fringing when shot at f/4.








I like the shots where I missed focus.

Q-S1 w/Kodak Cine Ektanon 63mm f/2.7 which has a built in helicoid for close focusing. I just got it mounted and am loving it on the Q-S1 and my M43 GX8.

Q-S1 with Zeika 38mm/1.4 D-mount.

Fly shot were taken while the lens had a C-mount collar epoxied to it, which acted like an extension tube.

Wide open.




Stopped down a tiny bit.



Stopped down more.



Stopped down to f/8 I think.





With C-mount removed, now has normal focus range with D-mount.


Wide open.





Stopped down slightly.



Stopped down and cropped.




I don't think the Zeika 38mm/1.4 will get anymore time on the Q-S1. The Kodak Cine Ektanon 38mm/2.5 covers the focal length and has the built in helicoid for close up work. I'm loving what the Ektanon can do on the Q-S1.

Hi guys I haven't visited in a while so have not updated the index.
Additionally it seems my photos that were hosted at Photobucket will no longer be linked in the forum as they are asking folks to upgrade to paid accounts.
I don't really have time to deal with any of this ATM.
If it is important and if someone is interested in maintaining the index send me an email to lnavarro1 at yahoo dot com and I can send the you the excel files and program that is used to create the index.

Hi crewl1/Larry, email sent.

BTW I wanted to thank you for creating and maintaining this thread for such a long time. This thread was/is the single most important source of inspiration and encouragement for me as a person who wanted to explore the possibility/capability of my Q7 beyond that which is provided by native Q lenses. I believe I'm not the only one who feels that way.

I cannot work on the index as frequently as you did but it seems like the work load is not as heavy these days. I'm interested in maintaining it. (By "it" I mean this thread, not just excel sheets.)

Best,
kwb

Lens table updated. Thank you all for your submissions, and thank you Larry for maintaining this thread for a long time.

There are some posts that were deleted by the users, and there probably are dead links too, but I'll leave them. I don't have time to actively search for broken ones.

Thanks for doing this and do not worry about the dead links. They tell us what was there once and that is also interesting if not immediately useful

We all owe a debt of gratitude to Larry for all his contributions over the years.

Thank you kwb for taking on the important job of keeping the adapted lens table updated. Your donation of skill and time allows this important resource to grow.

Don't worry about dead links. They add a little historical character.

Thanks for helping out,

Pentax Q-S1 Photodiox PK (A) -P / Q Adapter with lens: SMC Pentax-M 1: 2.8 28 mm


Nice results of the possibilities of the adapters in our dear Q-S1 .. !!!.
I have here the last thing I did with the K / Q adapter using a SMC Pentax-M 1: 2.8 28.00 mm lens and trying to close the diaphragm to F22
Hope you like....

I was looking for a small lightweight macro for my Q7, Q forum member (surfar) told me that he uses this lens, I bought a good copy from another forum member, and even though I haven't used it that much yet, I'm already liking it (thank you surfar)!

I'm very happy about the color and the sharpness. And this lens is much easier for me to hand hold than Vivitar Series 1 90mm 1:2.5 VMC macro partly due to its shorter 50mm focal length and partly because of its lighter weight (220 VS 650-ish grams). The following pictures were both shot hand held.

I can use it as a telephoto and it's good, though I prefer 06 lens for that purpose (can be almost as long, much lighter weight, F/2.8, auto focus).
