EOS Bodies / Re: EOS 7D Replacement Coming for CP+? [CR1]
« on: January 14, 2014, 09:34:05 AM »
Long time lurker here, first time poster...
I'd add to jrista's observations that the implementation of CFast here is probably not for burst rates anymore, but more for video.  As a current 7D owner, and a user of MagicLantern (or whatever it is now... TragicLantern maybe?), the card write speeds are far too slow for RAW video and generally pretty iffy for higher-bitrate H.264, so any card write speed improvements would probably be for video, not photos.  Even the 1DX has a buffer that will eventually fill up, and if Canon would try to design any camera to be able to sustain a burst, I'd expect them to work on the 1D series.  I certainly wouldn't say no to a sustained burst on a new 7D though!

I think you need to start posting, as you seem to know what you are talking about.  We can all benefit from your knowledge.

I agree!

It isn't a panacea, and as I said in my reply a few days ago, I use it along with many other techniques. The key is to capture the information at the highest quality you can, then find the best way to present that information.

My top three methods for interiors with problematic exterior light levels are; 1, bring the light up in the room with strobes, this can look ok if the room is smaller and the architectural lighting is not a key element to the actual space. 2, layer mask in PS. 3, PS 32bit.

I often end up using a combination of all three but will bracket the hell out of the scene to guarantee I have all the information in front of me.

On one thread about HDR techniques many months ago I wrote about all the different kinds of blending, HDR, etc techniques and posted a same image comparison, but it is one of many hundreds of my posts that disappeared for no known reason. It was funny, the thread was basically about Photomatix and how horrible it was, yet my Photomatix HDR rendition, not the blend, was very popular and showed none of the comedy HDR look we are all so familiar with. Photomatix is an extremely powerful program and has recently been updated, skilful use of it can make remarkably subtle images now.

This again highlights another aspect of forum anxiety, I regularly shoot in situations where I am severely low iso DR limited, not just by my Canon's DR range even the mighty D800 wouldn't help much, because of that I have fully explored all the techniques available to mitigate that and am aware of how to work around it. Meanwhile other posters are adamant there is no DR "issue". However, I am not placing myself on a higher plane, I am a noise nazi, can't stand it, as far as I am concerned even a 7D at base is too noisy, but only because I haven't fully explored every noise reduction technique to satisfy myself, because it is not a priority for me. For the birders out there who have to shoot at >800iso they do prioritise that technique so don't understand my frustration at low levels of noise. Yes I have Topaz etc, but you can't know everything about every technique, and as far as end result, what is acceptable to one person might not be to another.

Well, there can most definitely be DR issues in many kinds of scenes. Photographing interiors is probably the best way to exacerbate dynamic range to the ultimate limits. If that's what you do, you should be screaming for Canon to reduce read noise to less than 1e-, and demand full 16-bit output with 20 stops of DR. :P

As for the 7D, by todays standards, there isn't any question it's a noisy little bugger. It's sweet spot is ISO 400-1600, it does rather poorly at ISO 100 and pretty badly at ISO 3200. It isn't TERRIBLY far behind modern APS-C cameras, however it really lags pretty far behind modern FF cameras. Between the 7D and 5D III or 6D, the difference in noise is so massive, it's almost painful. Part of that is due to the 7D having smaller pixels, part of it has to do with the strong AA filter (softer detail is more prone to being perceptually noisier, vs. sharper detail with is perceived as less noisy, even when they technically have the same amounts of noise)...however the 7D's pixels seem to have a particularly low full well capacity. At 4.3µm the FWC is 20187e-, where as the 70D with even smaller pixels has a FWC of 26726e-. The difference in Q.E. is a mere 4%, where as the difference in full well capacity is 32%! I am not sure what Canon did with the 70D sensor, but they have clearly made some fairly significant advancements with their sensor fabrication as far as efficiently utilizing the minimal amount of space they have. I would love to see ChipWorks break down the 70D sensor design...a die shrink to 180nm from 500nm could account for the necessary increase in surface area to support a higher FWC.

Even more impressive is the D7100, which as a FWC of 29236e- for pixels that are even smaller than the 70D. Again, the difference in Q.E. is relatively small, 11%, but the difference in charge capacity is huge, 45%! Canon's 18mp APS-C sensor simply wasn't really a thing of wonder...never really has been. It's surprising it's survived as long as it has in as many cameras as it has, given it's rather lackluster low-level specs. I am hoping the 70D sensor becomes the new standard for low end DSLRs and the EOS-M. I also sincerely hope the 7D II gets a sensor with a FWC in the 30,000e- range at 24mp...that would help immensely with the noise issues.

Another brilliant post, jrista!
Learning a lot from you, neuro, Mt Spokane and others. Thank you all.

I got tired of waiting for the 7DII to upgrade my 60D. So I just got the 5DIII. If the 7DII shoots 10fps, 61 point AF and has thr same sensor as the 70D. I would be tempted to get one. Because I cant afford the 1DX.

Well, I will keep on waiting... :)
Good luck with the 5D3!

My crystal ball says it will use the same sensor as the 70D.

Hopefully you couldn't see right because your crystal ball lacks enough dynamic range. :)

I understand the OP wants to know how many of us jumped ship when "superior technology" became available from the other brand, and chose for comparison the 5D2 and the D800. I also understand it is his opinion that the D800 is superior to Canon's products available today as the 5D2 was to Nikon's at the time; otherwise, a comparison would make no sense.
So, I believe the question he wants answered here is how likely we (CR folks, big bias) are to jump ship when competition is clearly better, or if we prefer to stick to what we already have anyway.
(It seems likely to me people will disagree with the cameras chosen for such comparison, though.)

I've been using Smugmug for several years now. While I have minor dissatisfactions with them, they are adequate. I pay a reasonable price for a service level that gives me what I need.

Many more professional photographers I've seen lately seem to be using Zenfolio. I'd probably try them if I were not so lazy.

I abandoned Flickr when they did their "graphic" redesign. Now all your pictures look like they have been dumped into a blender. I still visit once in a while for the comments in groups -- you can find some good insight into particular bodies, lenses, etc. from people who are actually using them.

I tried 500px briefly, but they're too social oriented. It's all about campaigning to have members vote for your pictures. I quickly grew weary of all the needy pleas to "like my picture!"

I will give Zenfolio a try, then.

(...) but the interface and ability to truly customize is tedious and really cumbersome. (...)

Thank you for answering!
Do these problems persist despite the recent "upgrade"?

Dear CR friends,
Which of the hosting websites do you prefer, and why is it better for you?
Thank you!

(...) If you are unable to take decent to phenomenal shots with today's Canon offerings, which is by far one of the best and innovative systems on the planet, you should consider a different hobby/job.

Could not agree more.
I own a 60D and some humble lenses (17-55/2.8, 50/1.4), and even though I would like to have better high-ISO IQ, more DR, faster FPS, AFMA etc, etc, etc, I am pretty sure that after all those years my entry-level camera still longs for a better photographer behind its viewfinder.

I thought that it was generally accepted that they already have - a couple years ago in fact: the 1Dx
+1  Haha!!  So true! 

Another thing.. WHEN the 7D mark ii is announced, that is going to be the camera of the year.  Seriously, how long we've been waiting..  That's what I really want to see and I don't think I'll be disappointed.   ;)

Waiting anxiously for the 7D2!

Canon General / Re: What is the problem with Canon
« on: January 09, 2014, 02:11:18 PM »
Why has Canon not come out with their 50-100MP camera?

Because they can't make a business case for it.

The engineers tell management that the "new" camera will cost X
The marketing department tells management that the "new" camera will sell for Y
The sales department tells management that Canon can expect to sell Z number of units

The managment subtracts X from Y and multiplies the answer by Z.

The management then compares this number with a whole bunch of numbers that Engineering, Marketing, and Sales have no idea about and makes a business decision.

That's why Canon is not releasing their new mega mega pixel camera.  The numbers are not just right yet.

This why Engineering, Marketing, and Sales departments don't make these types of corporate decisions.

Great way to put it.

EOS Bodies - For Stills / Re: EOS-1D X Firmware Version 2.0.3 Released

Great! Now all I need is 7000 dollars.

Alan, thanks for posting these results!

Btw (hint, hint :-) ... unless shooting jpeg only use full iso stops, iso 320 is really iso 400 underexposed, iso 640 is iso 800 underexposed, you gain nothing by this but only lose dynamic range.

Do you have data to support that assertion?  You didn't respond previously

Btw (hint, hint), Bill Claff's data suggest that you're wrong, and that using ISO 160-320-640 gives less noise (as AlanF indicates) and also more DR than the 1/3-stop higher full stop increments of ISO 200-400-800.

As I stated in the other thread, it seems that from a noise as well as a DR standpoint, you're better off using multiples of ISO 160 than ISO 100 (unless you're using a 1D X, which has smooth noise and DR curves, unlike the jagged ones of other recent Canon sensors).

Very helpful and supported!

Neuro, this item definitely deserves some research - I'll try to shoot some high DR test shots this weekend at the various ISOs (on my 5DIII) and then run them through a battery of tests with the tools I have.

Waiting anxiously on the results!

Great bike!
Why did you opt for HDR?

I like how the HDR highlights the chrome and also all of the detail it shows in the tires.  I also like how it made the shadows look.

Thanks for answering!
