These photos were shot about an hour before sunset. I used a Fotodiox adapter with black felt tape on the inside.

F/5.6 - 1/200th - ISO 125

These photos were shot about 30 minutes before sunset. I used a Fotodiox M39 to Q adapter. No black felt in this one yet.

F/4 - 1/320th - ISO 125


F/4 - 1/100th - ISO 125


I'll update these with new photos and better samples (including 100% crops when I figure out how to do that).

Good work MerinatedHerring. You are doing well with the swimming birds. They are tough to shoot whan moving. Glad you tried the felt tape. Let us know how it works for you.

thanks

The Tokina is a keeper. Looks good and sharp. It is liberating to shoot macro from 6'away. So much fun.
thanks for sharing

Sigma Mini-Wide II 28mm f2.8

A lot of people don't like this lens. I guess I just got a good one. It's good on APS-C on now on the Q also. I also used it to shoot video on the Q and it did a great job.

The shot is soft because of the 1/20 shutter speed and my daughter being 7

Sigma 105mm F2,8 EX DG Macro

I made a macro test with this lens and as suspected it works just fine on the Q with the KIWI adapter as it got an aperture ring. It actually gets a bit of a purple fringing problem in some some scenes but nothing catastrophic. Sorry for the slight shift in composition between the pics, a tripod mount would help but I used kitchen stuff as a "bean bag" instead which lead me to shift the composition when focusing. Can you guess the subject?
Answer:

F2.8
The lack of DOF makes the image glowy, the Q exaggerates it. Not super sharp but reasonable but DOF is just too thin.



F4
Looks good



F5.6
Looks even better, probably the ultimate setting for macro.



F8
Looks sharper when viewing the pic like this but actually it's just the DOF tricking you, it gets glowy and mushy. Stacking to get here would be better.



F8
This one shows a bit of of the purple fringing and greenish spots in highlights.



F5.6
Looks sharp to me and renders nicely, slight purple fringing and CA here two but not much. Who wants coffee?

OK, so looking at the successes others have had, I bought the adapter (RJ Pentax PK PK-A AF DA lens to Pentax Q adapter with tripod mount aperture ring), so what am I doing wrong?
My pictures are 100% c**p. Hazy, out of focus (even though I enabled focus peaking) and CA like I need 3D glasses to view the pics.
Tried the 30mm SIGMA prime, the 18-250mm DA and the 18-55mm DA. Just rubbish, rubbish results.

The Q always shows AV on the screen, the aperture rind is useful - but it's not helping.
Hand held or tripod, I'm getting truly bad results.. I mean shocking bad..

Someone have a step by step fool proof process to use let's say the 18-250mm with the adapted Q?

Some lenses just don't work well with the Q. The 18-55 isn't good on the Q, at least in my experience. The 18-250 is a great lens, but is also a superzoom and is not likely a good match for the Q. Because of the Q's sensor size, shortcomings with any lens (CA and lack of sharpness for instance) will be much worse on the Q than on a DSLR.

If you have some good primes, you might have better luck with those.

Since you have the adapter with the ring, if you're using a DA lens without an aperture ring, that's where the ring on the adapter comes in. Otherwise when I use a lens with an aperture ring, I turn the adapter ring all the way to the "lock" position & use the ring on the lens to adjust the f-stop.

The sweet spot for most lenses on the Q is f:4 to f:5.6. Stop down further and diffraction cuts down on sharpness.

Even then, you're probably going to need to apply some post tweaking to get rid of CA & get the best result.

Good luck,
Bobbo :-)

Sounds frustrating! I won't say I have the answer, but here are some thoughts. Moderate CA that not particularly bothersome on the DSLR gets magnified to become shot-ruining when using that lens on the Q. I consider my A400/5.6 a fine lens, but it is basically unusable on the Q (the slow max aperture doesn't help). I've also been trying my macro lenses, both of which have sterling reputations, and so far I'm not convinced that either is up to the Q's resolution. Camera shake also becomes magnified; some tripods that are good enough for the DSLR just don't have the stability needed for the Q. Don't forget the issue of diffraction: f/5.6 is pushing the limits on the Q. Finally, a great many of the stunning shots we've seen from the Q have something in common -- the DA* 300. I've been doing some testing and am realizing just what an amazing lens this is -- resolution way beyond what is needed for its native format.

Also wondering about the issue of reflections inside the adapter, that others have discussed.
