Well, it did arrive sound and safe, and I took it yesterday to come to our lunch. Not good pictures but quite promising shots:

#1 Shopping center close to where I work:


#2 Our colleague jlsa05 at his office entrance:



#3 Classical motorbike exhibition at the shopping center:


#4 My dessert


#5 A gllass of... bread


#6 Couple of water bottles


#7 Wide open (1.9), close focusing


#8 Our colleague Paco (Nikon & vintage expert)


My first impression: good light deliver better results, high ISO is not the main course for this small nifty cam. Otherwise, not as bad as its reputation in the specialized magazines.

I'm waiting for the M42 & C adapters just to try the Tokinas: moon shots (M42+ Tokina 300mm ) and the Tokina 8mm f/1.3 C lens.

Looks promising Jes, I look forward to seeing results with some vintage lenses.

Thanks, Tony.
It seems better for close shots (with this tiny lens), but I've to experiment yet.

I remember looking at this camera in Jessops. The saleman told me not to buy it as it was a gimmick. He didn't try to sell me anything else instead.

Well, a bit gimmickstic it is Wink (and your salesman also...)

I'm still waiting for the adapters. Today I've shot some outside pictures, to see if the results improve over the low light tests, however it was not the best day to do any testing: cloudy, windy and cold. (yes, we use to have some Wink )

It's really getting to the point with each incarnation of sensor technology, that its getting harder and harder to justify hanging on to these big old clunkers when things like that are simply available.

Colours, Tick
Resolution, Tick
Auto Everything, Tick

Just what else (apart from compensating) are we missing out on. Laughing

Works to me only on close shoots Jes, distance shoots is not for this camera. Look forward more, congrats to have a new cam to play.

Thanks, Attila. That's also my sensation with this 8,5mm lens, much better for close shots.
I'm still waiting for the adapters and some C lenses to arrive. After the "ferrick" samples, I'm hopeful to get better results with old glass...

In the meantime the adapters arrive, I've doing some more testing.
Attila is right, the 8.5mm prime lens is not good for far shooting, but much better for closeups:

The shots of the tower block are actually not bad, acceptable certainly.

Jes, haw do you find the Q's files respond to sharpening? I would hope that sharpening doesn't make noise apparent, which I have found to be an issue with older small sensor cameras I have used.

Ian, I do apply a very slight sharpening only when strictly needed. I use Lightroom 4.3 that has a "mask" control that allows sharpening only around the edges (it makes no sense to try to sharpen plain colour wide areas) and it's very little obtrusive, so it's difficult to tell. Which tool do you use for sharpening?.

Some findings:

Pentax Q autofocus doesn't work well for close shots at the near end:

This is the closest I can get letting the cam to focus (single centered focus point):



and this is what I can get with manual focusing:




Both shots at cam's narrowest aperture ( f8 )
