Hi All,
This is getting interesting. . .
I've only had a few opportunities to shoot the Q with my SLR lenses. It's challenging to nail the focus, but I'm getting the hang of focusing with the LCD. MF is tricky, even with the MF Takumars and their long focus throw but it's possible, even for me. . . When I get a K>Q adapter with a tripod ring, it'll be a lot easier.
All of these were handheld, shot in jpeg, the D FA 100 and FA 50 shots were cropped to 8x10, the Takumar shots are all uncropped. All were PP'd to taste with Dnoise and Infocus only, and resized for posting.
The FA 50 f1.4 allows focusing to @ 1.5 ft, so as @ a 180mm EQ on APS-C, allows some available light close up capabilities.

The D FA 100 f2.8 Macro is EQ to using a 360mm Macro on APS-C, so ultra close ups indoors are a possibility.
D FA 100/2.8, 1/100, f2.8, ISO 1250

Outside the slower M42 Takumars are small, so much more handy, the FLs are longer, and the MF feel is helpful for faster focusing. I used Pentax original M42 to K adapters. Both of the K mount lens adapters were loose on my camera's K adapter, so I stretched a small rubber band over the lens mount which added more friction so the lens doesn't rotate when focusing or adjusting the aperture ring.
The 135/3.5 Super Takumar is EQ to a 486mm on an APS-C. It wasn't long enough for the distance I was forced to shoot at, so I only took a couple of shots with it. It's rated @ 8.33 on the PF lens database.

The 200mm f4 Super Multicoated Takumar is a very nice compact 200mm for use on the Q. It's EQ to a 720mm on a APS-C.

Just to give some perspective, here's a shot taken with the 47mm EQ prime from the same spot as the Takumar shots, about 15 ft away from the tree.
These shots are not as good as I can get with my DSLRs and 510mm and 714mm lens/TC combos, but, considering handheld with no SR at 490mm and 720mm EQ, MF using an LCD, and "consumer" grade tele primes that cost me less than $20 USD each 6 years ago, they're not too shabby with the Q. Shooting from a tripod would help considerably. Shooting the Q with super tele lenses, despite the very light weight is very challenging, but fun.
The one thing that's a bother though is that these 60's vintage lenses don't have the ED glass to control PF and CA, and with the very high pixel density of the Q, color aberrations that are barely noticeable on larger sensors are very evident on Q shots, especially when super accurate critical focus is hard to achieve. I've got a good method of eliminating these aberrations, and don't mind them, but more modern lenses with better color aberration correction would probably be better for the Q.
All in all, so far the Q is living up to my expectations as a digital TC. I think that when I get the K>Q adapter with the tripod ring, the A*200/2.8 and FA* 300/4.5 will do even better.
