Q sensor dynamic range

I am really surprised at how well the Q maintains detail in underexposed shots.
I shoot the Q and adapted lenses in manual mode and when changing scenes the Q display auto adjusts so I constantly forget to check the meter and reset the shutter speed.
here is an example of a shot that was under exposed, but if I had wanted to save it I could do so with just a slight hit of noise.
Luckily in this case the birdie stuck around long enough for me to adjust the shutter speed, but if this was the only shot I could get I would be OK with the ability to save it.
BTW, to date I only shoot JPG - I know that I can go to RAW and have even more latitude on these shots.

These were shot with the DA*300 at f5.6 using ISO 125. The dark pic was shot at 1/3200, the correct pic was shot at 1/400.

Comparison of original and fixed in Lightroom


Fixed shot.


Correctly exposed shot.

Yeah, at minimum iso there really is a lot you can do. The problems don't creep in until you crank that up

I shoot at 125 pretty much all the time. Initial testing on higher ISO was not so great, but I haven't revisited it.
So this performance is nothing out of the ordinary? Good to know.

Expose right works well too

What I found, quite by mistake on a visit to the dog park on a bright day, is that overexposure in RAW mode can be pulled back by a huge margin (3 stops or more). It was so bright that I couldn't see what the camera was going - VF could be made out to frame the shot, and that was about it. So, a very washed out ISO 1250 shot was still salvaged - it amazed me:

This was shot with the 02 lens using expanded ISO TAv - no idea why the metering system got so seriously fooled. Processing was LR 3.6

That's good info Jim and the shot looks great. I've been telling myself it's time to switch to RAW. I like your album.

That's very interesting. I've been shooting pictures of my wolfiepup and noticed with a high ISO and a crop of 50% give or take the noise factor is pretty high. Then again, I don't have lightroom. I use faststone and photoshop 7.0.

I have shot both raw and jpg and find the problem to be the same. I wonder how much is user error on my part. I've only had the Q for a week and am using it intermittently throughout the day with the 02 and 01 lenses.

With the classic Q the noise starts to creep in fairly early.

With a good denoise software you can make the shots look better but you will lose detail.

Try to keep the ISO down if possible.

The Q flash is pretty efficient and since it is offset the pictures don't look too bad, dont be afraid to try it.

I've been very disappointed in super low light situations with fast moving toddlers. I feel like I've gotten better shots with my phone.....
