BTW -- I received this statement from from Canon sales/product support, when I asked specifically about the 5D3 utilization of the flash AF asssist, and if the 6D suffered from the same malady:

"... the camera does support the AF Assist Beam from the flash, so the EOS 6D should work the same as well."

interesting...

love the 10-22.  just to lighten up the mood, here is a wave that hasn't crashed yet lol.  taken with the 10-22 REAL close.  no underwater housing.  camera moving with the wave firing away at 6fps.  I got drenched but the camera didn't :D

Wow!
Just wonder why do you have so much magenta in the left upper corner, is that color fringe or famous red noise, which may be the case because the same thing you can see on the lower right in the dark parts of the water with no contrast.
In case if this was produced by the 10-22 lens, you probably have a bad copy.

well, now you have me doubting that this was in fact the 10-22;   the no contrast in the water could be flare, and this could have been the 17-55, although the color fringing at the top of the wave is characteristic 10-22. 

as for the magenta itself, I suspect that is an artifact of heavy pp;  probably pushed the red sat slider too far. the colors were pretty wacked in post, so that the wave didn't appear too green and poluted :D

 :)
Depth of field seems bit to shallow to, you know, I have taped the focusing ring on that lens and using as fixed focus most of the time!
It has enough depth for regular landscaping work even at f5.6, the only problem is when I have to, very rarely zoom in, it needs small correction to the focus.

yes, I had the CP on, and now I think this was taken with the 17-55.  my apologies for drifting the thread here.  also -- part of the reason the foreground is not sharp is due to motion blur --  the camera was held at about a foot from the water surface in front of the wave,  without me looking through the viewfinder, and moving rapidly in many vectors to pace the incoming wave.  at the last moment I stuck the camera into the air and took the wave, which was probably only 3 feet high, I would say.  I think the lack of contrast is partially due to lens flare, and the magenta cast is partially because red has been pushed to bring out the sand, which was only a few inches below the water surface. 

I just put this photo up for fun.  please continue with the OP's inquiry, and discuss the other related shots

Great start!  I really hope that Mike the product expert can do more than just provide an SME presence on the forum to assist with understanding and using the equipment.  He needs to be able to influence or at least inform the individuals that can apply resources to address this issue, and not just talk about it.

EOS Bodies / Re: Possible positive 6D surprise? Should I wait?
« on: November 27, 2012, 12:00:45 PM »

I think it's fairly clear Canon had a specific type of photography/photographer in mind when they designed this system.  Namely people who don't shoot many fast moving subjects, but need to focus in all kinds of light.  Portrait and landscape are of course two that come to mind.  If you look at it from the perspective of that type of photographer, the -3EV center cross-type should be outstanding and clearly an upgrade from the 60D/650D, since the other points almost don't need to be there (even on the 5D3 the most precise points are in the center).  The sports/action/wildlife photographer is right to say this system is unlikely to be good for them - and get a 7D or 5D3.  I realize this isn't what a lot of people were hoping it would be, but for some this may be just what they needed (without the expense of the 5D3).
..

Some good points here.  6D looks to be very 40D like in that regard --  aimed at center-AF dominant work:  "grab focus;  then frame".  Whats interesting to me is that, while the -3EV center point on the 6D is attractive, to be sure, all the other points are +.5EV sensitive, which means the moment you pick a different focus point, the 5D3 clearly wins AF sensitivity by 2.5 stops .

getting back to the original topic:  I suspect one reason we haven't heard more about the 7D2 is that Canon is trying to protect holiday sales, and may announce something soon into 2013.  They've telegraphed the big MP FF (to keep people from jumping to Nikon I suppose) but they have not telegraphed anything re:  the 7D2

on that topic, what if the FF 46mp monster and the new 7D2 crop sensor are based on the same process?

I bet it is :)

and the natives are restless for want of information!

... I have my doubts that Canon can get anything more out of the current 500nm process.  I suspect that any significant improvement in Canon's APS-C sensors would require a move to a newer process.
I have my doubts that we will see anything being announced before February or March next year, so we probably still have a while to wait before we see Canon play its hand.

What I suspect would be a likely approach from Canon is to move its APS-C sensors to a new process - possibly next year, while it carries on using the 500nm process for full frame for another 3 years or so, until the 1DX and 5DIII are replaced.  That would probably be done in order to achieve the required manufacturing costs.

That theory does square, in my opinion, with the fact that 7D2 rumors are quiet, while the 7D1 ages mercilessly, and yet Canon has already introduced a new crop sensor in the t4i.  What will be interesting to see, should this come to pass, is what IQ level can be acheived, how it compares with the current FF lineup, and what we might learn (by implication) regarding what Canon's future acheivements in future FF sensors.

on that topic, what if the FF 46mp monster and the new 7D2 crop sensor are based on the same process?

EOS Bodies - For Stills / Re: Would I benefit from going full frame?
« on: November 08, 2012, 04:15:44 PM »
my 17-40 on full frame is inferior to the EF-S 10-22 on crop.

My experience too. Is that what others have found, or did I have a bad copy or didn't spend enough time with the setup?

I'm thinking thats why God inspired Canon to invent the 16-35 II :D :D

on a related note:  with the recent introduction of the 24-70 F/4 L IS, at $350 more than the 24-105 f/4 L IS, I wonder if the latter is due for an update and price increase

To me the picture is a big deal because there arn't very many other ways to get such a dramatic capture.  Cost aside -- from requests to the pilot (lets go over there, no up higher, now over here.  try 500 more feet ... ahh thats it...) and strapping himself in dealing with the cold and the 1% keep rate, it all shows what one has to do to get shots like this.

I would only disagree that the 6D IQ will surprise people...unless those people actually expect it to be much better than any other Canon sensor. Canon has not yet demonstrated an improved manufacturing process, so it is doubtful that the 6D sensor will be radically changed in any way.

true dat.  and extending this logic, one has to conclude that whatever sensor the 7D2 gets, it may be incrementally better than the 7D1 but still won't compare with 6D or 5D3.  I mean -- even if they could, its not likely that Canon would produce a crop body that would exceed the IQ of a more expensive FF body in the current line-up.  It wouldn't surprise me to see (in the 7D2) an increase in MP count, improvements to AF and perhaps even fps, and a measureable improvement to the ISO and noise performannce, but I guess I'm not expecting to be astonished by a market-disruptive IQ or DR.  is anyone else? 

someone in another thread (pardon the lack of reference) has already suggested that Canon has telgraphed their FF sensor offereings for the next 2-4 years or so, with the 1DX, 5D3, and 6D releases.  The big mp body is the unknown at this time, and I suspect this one to be optimized for DR and low ISO, expecially its first release I doubt it will match the ISO performance of the 5D3 for example.

but they have not telegrahped their crop sensors for 2013, and the silence of the 7D2 in this regard is defening.  I can only hope that the delays mean a new sensor and not a re-worked t4i sensor.

EOS Bodies - For Stills / Re: 5D Mark III sensor cleaning noise (squeaks)
« on: November 06, 2012, 02:06:33 AM »
I have had two 5dIII (returned one) both made 2 high pitch noises when turning it on and off while it said it was cleaning so I would not worry about it. I am also one of those can can tell if a crt is on anywhere in the house. And those damn apple chargers for their laptops drive me crazy with their high pitch noise!

If you are hearing CRTs from NTSC Televisions, you know you can hear 15.7 KHz then :-D  Computer monitors generally run well above the threshold of human hearing. For example, a CRT capable of 1024 lines at a 60 Hz refresh rate runs at about 64KHz, which means in order for these devices  to be audible you would have to be hearing some subharmonic, which of course is quite possible. 

laptop chargers are a different animal.    Unlike the CRTs with flyback transformers, these are switching supplies running well above the audio range,   However, it is still not uncomon for these to produce some subharmonic mechanical vibration or even a real resonance in the audio range as a side-effect.  It wouldn't suprise me if these produce acoustic energy well below the upper threshhold of human hearing.

lol nice work TAF I hope your cats survive the experiment :D   indeed,  bypassing the natural low pass filter of the ear is comparitively uncharted waters.  Here's hoping something useful appears in time for Mt. Spokane!  :D

EOS Bodies / Re: 46.1mp Canon DSLR Previewed at PhotoPlus 2012? [CR1]
« on: November 01, 2012, 07:11:20 PM »
This might be off the wall for hard core students of Canon history who can predict what Canon will do -- but it will be interesting to see which of two paths Canon will take with this puppy.  Assuming this is a 5D style camera:

1.  further the specialization (and sale) of different bodies by preserving both a 5D and a high MP camera, optimizing each for their respective niches and preserving the sale of both, i.e. a 5D4 appears in addition to the 46mp body. 

2.  compete more directly in the D800 style market, but at a higher price -- , i.e. merge the 5D and high MP lines into one  camera that can play well at both 46mp and 21-ish. Use it for studio, landscape, location, wedding, lightweight sports and wildlife.    Odds are that the 46mp body won't appear until 5D4 time anyway :D
