Just wondering if that 2.8 of the D10 would be the decider. 
IMHO it's a wash for lightning photography.  Buy which ever one you can pick up cheaper.

The D20 does suffer from chromatic aberrations probably more than the d10 (looking at the d10 image samples I've seen). And images aren't always that sharp with the d20. Another thing, the d20 also has a horrible orange lens flare that appears whenever the sun is in the image (not that it would matter for your lightening shots though). I can probably upload some examples if you want.

ISO 600 is still quite a bit for the D10 I'd imagine, even on the D20 I'm reluctant to use ISO 400. I've heard though that the D20's high ISO performance more than makes up for it's smaller aperture when it comes to noise.

Keep in mind that the D10 only goes down to 35mm while the d20 goes down to 28mm which was one of the major deciders for me choosing the D20 over the D10

I'm sure however that the D10 is less likely to get stolen as it looks more like a teletubbies toy than a camera (then again, the D20 does too...)

So, like I said, it's a wash for lightning photography?  Buy which ever one you can pick up cheaper. Otherwise pick the one you like best based on Recyclojunk64 review.

Alright, thanks dudes.  Either one it is.

If I zoom in a bit on these powershot cameras (all models) in general does the picture get sharper?  I know that's usually the case on my stand alone lenses for my GH2 but does that also follow for all of these point and shoot cams, zoom in a bit where the lens is sharper?  If yes then I'd lean towards the D20 and its 28mm side. Thanks.

I've been thinking about purchasing a used D10 or D20.
The D20 is superior in every way except aperture. I doubt that underexposure will be a problem with lightning photos. A bigger issue is the field of view. The D20 has a wider field of view, so you'll see more sky and thus, more lightning bolts. You may even want to try video mode for lightning. The D20 has HD video. The GPS may be useful too.

I haven't tried the D10, but the D20 is great in a storm. I tried putting RainX on the D20 last night, and did a time lapse in a nasty storm. One of the local TV stations used it in their news broadcast today:

Lens flare and reflections with the sun in the frame are a problem for any camera. The D20 is better than most, because of the simpler lens. The super-zoom SX50 is horrible, and the G1X is  a little better than the D20.

I put the D20, G1X, and SX50 on a camera bar for these three time lapses, with the sun in the frame at the very beginning, if you'd like to see the lens flare/reflections:

G1X: http://www.youtube.com/watch?v=tDtN6FqtgIg#ws

SX50: http://www.youtube.com/watch?v=80_k6QMq3ao#ws

I haven't noticed the sharpness problem at wide angle, but I haven't looked closely. I assume it comes from the lens distortion correction when creating the jpg image from raw.

We don't get much lightning where I live, but I have tried to capture meteors a few times. For that, I want the widest field of view possible. I assume you will too, since you never know where the lightning will be.

Nice videos there.  The GX1 did look the best, which it would.  Thanks for the tips.  I'll find a new/used D20 before summer starts.  We get some nice lightning here in the summer.

Yeah that's the orange circle flare I was talking about. Not that bad compared to some other cameras, but still quite annoying (especially for me as it will ruin a stereo photograph). While the lens is simpler than a superzoom, is still a compact 'periscope' lens (unlike the D10) so does have it's limitations (image sharpness and CA mainly). But I would agree the D20 is still better overall, and compares quite well against many of the other rugged compacts released at the same time.

Here are some test shots at different focal lengths:

Test2
All at ISO 100

Yeah better off going with a used one, I got mine for less than $150 each.

On the topic of the D20, I would like to express my disappointment with the new D30; after two (or was it three?) years of waiting, it's almost exactly the same as the D20 except it's got a redesigned case (so it can go deeper underwater). It's still stuck on digic 4 five years after the D10 was released!

Try using www.imgur.com for photos you want to post here. It's free and you don't even need to register. I uploaded the images here:

If you click the tool icon on the pictures you can view or download the full resolution.

Those pics all look pretty good to me, but I'm not a pixel peeper.

Thanks.  Saw the pics now.  Well, two comments:
One, I agree.  I can't tell much of a difference either but I too am not a pixel peeper. Thanks to the original poster for doing that.
Two, I'm stuck up here in frozen northern Wisconsin with 22" of snow in my yard and you send pics of your tropical paradise living?  Not fair!  Not fair!  :xmas
