The DA70 LTD is an excellent small lens that on the Q will offer a 385mm equivalent reach.
Hand holding is easy as the Q's SR is very effective at controlling shake.
The Q is brutal on lenses so even though this lens is wonderful on APSC, on the Q it shows some deficiencies.
Wide open at 2.4 you will see quite a bit of purple and green outlines in high contrast areas.
The lens works best stopped down to around F4 where the CA gets under control (position 2 on the adapter.)
The manual focus ring is a little slim so focus is not as fun as with the older manual lenses.
The great thing, though is the DA70+Q is a tiny package that can make it easy to get those long range candids.
Also, the bokeh is very nice from this lens on the Q.
It's raining here so sorry for the crappy subjects.
F4 ISO800 1/20 (handheld on a 385mm lens, thanks to the Q's great SR!)
F4 ISO125 1/60 hand held again
With better lighting you can stop down further to reduce the CA. I don't recall the settings on this early shot but it does not look so bad. Probably f5.6
