Thanks Humayun. That's Canon Canada BTW. Still hopeless though... the whole mess needs a clean out and re-design. Consistency between markets would be a start... Great software however.

Sorry, yeah, I grabbed the link off DPR yesterday. The *.au site is probably a bit slow in updating.

And, you're right, the software section of Canon's site is a bit of a shambles. Although, luckily, you only have to go there once every few months, so, it's not too arduous.

I have been playing with the camera at work and am even more impressed than my first play last night. Fantastic!

High ISO performance is impressive - certainly beats the D800 on that example.

hey H.. looking nice. guess i won't be able to put off getting one for very long :-)

any chance of a 5DII vs III comparison at max ISO on the II vs same exposure and ISO settings on the III?

Phil

I read a figure by Sensorgen which put the Mark III having a 49% QE figure.

I went up to take a picture of sunset this afternoon, but, the clouds went all lame.

Try again tomorrow.

Those images certainly show up the shortcomings of the 85mm F1.8 lens.

Wow. Check out the full size file. How much does that lens cost??

It just goes to show the standard required for telescopes and astrophotography is much higher than terrestial photos.

Greg.

Hey Greg,

Yeh there are lot of "seagulls" in that image, but its amazing what you can record with just 5 second exposures and a cheap 85 f1.8 lens (they are about $500 or so). I was looking at the LMC shot and you can see mag 13 stars even in that jpeg.

Yes good point. Incredible amout of signal recorded for 10 seconds.

I was thinking of the $2000 85mm F1.2. $500 is cheapish in the lens world.

Great site thanks for posting that. I often wondered what the QE was for various DSLRs. Gee thats up about 50% over 5D2. They should push that more.

Also I see D800 at 57% with quite deep wells. This could be good for astrophotography as my Proline and 8300 cameras are 60% QE and I am used to that level of sensitivity.

Both these cameras should be awesome for time lapse. There's a reason for Phil Hart to get one over 5D2.

Have you taken any night shots yet H?

Imagine these cameras modified for astro?? Wow, their QE would hit much higher levels and up around or beyond normal CCD levels.

Imagine a mono 36mp Sony Exmor sensor in a cooled CCD cam. Geez I'd buy one of those. Its QE would be way over 60%. Also those read noise levels are really low.

Both those numbers are impressive. Kodak never achieved that with a Bayer matrix sensor. Have DSLRs caught up with some CCDs now??

Greg.

I bought my 85mm f/1.8 lens for $360.

It is a sublime portrait lens, but, would be no good for astrophotography.

Example.
