I took these two moonies within minutes of each other on October 3rd using my 70-200 f/2.8VR with a TC-20E III 2x tc on my D300 (first shot) and D7000. Interesting how the denser pixel count on the D7000 seems to give more detail. (Both shots handheld.)

This should not amaze you. The more pixels you can get under the subject (due to pixel density) the more details can be captured.

Love the details in the craters on the right side.

Really nice shots. Yes, the added resolution is visible, when cropping especially.

Being a D7000 owner too I am not surprised but I am still impressed with these shots but I'm equally impressed with the 70-200VR and your tc20III. That VR really works. Nice comparison.

Very impressive images. I'm somewhat confused though by what appear to be radical differences in the exif data between the two shots. If the D300 shot really was a 1.7 second exposure and the D7000 was 1/1000, I'm not sure your D300 was given a fair chance to compete for detail

I would expect to see a similar difference if they were both taken with the D7000. Even with VR a shot at 1.7 seconds should be softer and show less detail than one at 1/1000.

I'd love to see a comparison like this with identical exposure settings on both cameras.

Neat shots!

I too was looking at the EXIF. The D300 EXIF says f5.6, 1/500s, ISO 400 and the D7000 EXIF says f8, 1/1000s, ISO 200. This doesn't make sense to me. It seems the D300 shot was made 3 stops brighter exposure than the D7000. How can that be? Adjustments in post?

I would also think that an f5.6 (fully open aperture) versus f8 is an unfair comparison. So is 1/500s versus 1/1000s (including when handheld).

I do agree that higher pixel density would bias the D7000 to a sharper image.

Peter, thanks for your feedback.

As I was shooting, I had to change the exposure on each shot until I started getting viewable images.The first shots were over exposed so it meant having to play with WB until the shots were adequate. This is why the settings were different. At the time, I was not trying to compare the two cameras. That was an afterthought. If I had intended a "fair" comparison, I would have tried to use the same settings on both cameras as you suggest. This was not my intention. Try shooting moonies hand holding the gear I was and you are glad just to get bursts of shots before you have to lower the rig.

Hi Spencer,
Yes, the lens-tc combo is really good.

Thanks for your comments, Chris.
As also noted above, it would be interesting to try using the same settings on both cameras. Next time, I'll use a tripod as well and set up both bodies so we can see what the results would be then using the same lens setup on both cameras.
I'm not sure why the exif data gave that 1.7 sec. number as that was not the case. It was actually 1/500 sec. as Peter noted.
Cheers.

I'm thinking I may need a different EXIF plugin on my MAC. Will check that this evening. That EXIF report really doesn't make any sense.

OK, that makes sense, thanks.

I find taking a picture of the moon to be very rewarding.

My first thoughts were (a) the D300 shot is over-exposed, and (b) it really looks like it was hand-held and probably shouldn't have been.

From your explanation I think the results could have gone either way irregardless of camera used.

I find my D7000 does beat my D300s in pixel peeping, but the gap is nowhere near what you've demonstrated here.
