no sir you have it all wrong your zeal on bringing the so called truth is mind boggling remember sony dat tec? or Betamax and the list is so long of failed items its scary.and digital cameras I got a box point and shoots plus the majic memory sticks don't even say sony is best its not.+1 these forums are less about photography and more about fighting...
So feel free to continue staying away.I'll tell ya. The best thing I ever did was leave this nutsy forum and just DO photography. .
Interesting that your website is still full of 7D wildlife images then, don't you think? Where are all the superlative Sony shots that blow Canon out of the water?Just keep talkin. You are making my case for me.
Good to see the old vitriol and hate is alive and well here on CR. *sigh*Interesting that your website is still full of 7D wildlife images then, don't you think? Where are all the superlative Sony shots that blow Canon out of the water?
I suppose we'll be waiting a while for them, eh?
Thanks, Don! AP has really consumed my imaging, just about entirely. I am actually trying to get back into some terrestrial photography, as I haven't actually done much of any the last couple of years (some floral and fungal stuff mostly). While I am not a huge fan of Canon sensors, I'm a big fan of their glass, and it is well past time for me to upgrade some of my EF lenses (which thankfully, due to their decent backfocus, work on pretty much every camera I own regardless of brand. ;P)Jon, beautiful!
Hi Jon!Good to see the old vitriol and hate is alive and well here on CR. *sigh*
I have been doing astrophotography for years now, and it dominates what I do. ... Here is one of my latest works...
Thank you for sharing your experiences and knowledge. I sometimes really missed that.... I work with quite a few different kinds of cameras,
... Sony IMX183 sensor ... some of the most beautiful raw data I've ever worked with
... I now understand that Canon's sensors suffer from relatively high FPN ...

I have been doing astrophotography for years now, and it dominates what I do. I work with quite a few different kinds of cameras, and have processed data from dozens of different kinds of cameras, including DSLRs as well as scientific CCDs, astronomy CCD and CMOS cameras, etc. Sensors from Canon, Sony, Panasonic, Kodak, OnSemi, Aptina, and others. I routinely work with signals orders of magnitude fainter than anyone doing terrestrial photography works with (fainter than starlight, and starlight is darn faint!!).
I know how to process just fine. I am intimately familiar with faint signals and how to extract the most from them, and how different cameras compare in terms of noise and signal quality.
Here is one of my latest works, in this case with a Sony IMX183 sensor, 2.4 micron pixels, at about 1.9e- read noise and gain of 1e-/ADU:
This is some of the most beautiful raw data I've ever worked with, and acquired with a relatively modest aperture...and with very tiny pixels. Canon data doesn't come close to this kind of quality. I've processed very faint signals from every major Canon DSLR on the market (I now understand that Canon's sensors suffer from relatively high FPN, which is more of a problem for them than other noise terms, and even with dark calibration, their FPN is often unstable and does not always correct properly). I also use a Panasonic sensor regularly, and it performs very well as well...and in some respects, is actually superior to most of the Sony sensors I use. The only thing that can top the Sony IMX183 and Panasonic M IQ is data from a KAF-16803 (originally Kodak, now an OnSemi CCD sensor with very large pixels and immense dynamic range) when paired with large telescopes...however the camera alone costs at a minimum ten grand, and telescopes that can deliver comparable results with this KAF camera tend to cost eight to twenty grand or more. The KAF-16803 also requires some fairly extensive total exposure time with long individual exposures when operated at similar image scales (here, ~0.82"/px for the image above).
I have not tried taking any pictures through my telescope since I used slide film over 15 years ago. I imagine that the old Canon mount for the telescope might work with my current digital bodies, but I haven't tried. Light pollution around here is too great to photograph much of anything. Even back then, I don't think the clock mechanism was that accurate. I got some decent shots of Jupiter, but didn't try Saturn, though it was relatively close at the time and looked good through the telescope. An exposure long enough was too likely to be a blur, so not worth wasting film on. Also eyeballing the angle to Polaris with my equipment that is rather primitive by modern standards would have given even more of a tracking error.Personally, I have been getting into astrophography as well. My understanding is that the most important gear is a good tracking mount and astroguider, and knowing how to process images and what type of images to take is far more important than camera choice.
