Will this be the first time Canon comes with two versions? I so doubt this….

Fourth time - 20D/20Da, 60D/60Da, 6D/6Dn are the first three.

The two Da versions are relevant, the 6Dn isn't, that is like saying the 600-EX and 600-EX-RT are different, technically they are, but the exclusion of locally restricted radio transmissions isn't a big deal.

But you are missing the big ones, 1D-1Ds, 1D MkII-1Ds MkII, 1D MkIII-1Ds MkIII, 1DX-1DC, the last two might be very similar but have very different capabilities and do have different hardware and firmware.

Canon will make what they think they can sell, and leveraging the 5 series family will likely prove much more profitable than the 1 series. I still like the common sense of a 5D MkIV (MkIII but 'better'), a 5DS (high MP), and a 5DC (video orientated), to me that makes a whole lot of sense.

Thus far, I have not sold anything over eBay because of the practical limitations I have living here in the middle of nowhere. From what I have heard, an individual seller can lose his money and the sold item very easily when the 'buyer' signals a problem with the delivery or the object itself.  If I send something valuable to Waziristan and the person says that the item was not delivered, PayPal will retire the sum from my account until the affaire has been settled. Which can take until the war is over.

I am selling now some lenses on the local net site and the scammers from Cote d'Ivoire are out already, smelling an easy prey. They use the free SMS service 24682 that I know already from their previous attemps.

There are some geographical areas that are better avoided. From a person's name you can get a hunch, also.
World is racist.

I just limit the listing to USA, ship to confirmed address only and get signature confirmation, that negates all you concerns.

Lenses / Re: Purple fringing of 85 1.2ii

Damn this thread!!  I watched Citizen Kane on DVD tonight and for the first time I was distracted by the purple fringing in a lot of scenes!  How the hell you get purple fringing in a black and white movie I don't know but I do know it wasn't shot with a Canon 85 1.2 ;D

The copy of the film that they digitised would have been one that was duplicated onto colour film stock, what they should have done is re B&W'ed the digital copy.

Canon received my 50L and my 5D3 on Tuesday.  Today is Friday and my gear showed up this morning.  Pretty fast service, I'd say!  BTW, I am a Gold CPS member, which probably speeds things up.

The really great news is that the lens now focuses perfectly!!!!!!!!!!!!!!!!

I tested the center point and all four peripheral points and they are right on the money with no AFMA.   I also checked for focus shift with aperture changes and did not find any at my usual six foot test distance.  If I recall correctly, that was only a problem at minimum focus distance anyway, according to forum posts.

Sorry I can't comment on curvature of field, I don't have any brick walls handy!   ;)

The service note says that they only adjusted the lens, not the camera body.  Apparently some optical assembly in the lens was still decentered after their first attempt at repair.    They did clean the 5D3 body, including viewfinder and sensor, and they reset my custom functions to the defaults.

I am a very happy photographer right now!  :)

Nice. And great news too........

To Privatebydesign... I had not thought to use a 1.4 TCR on my 24TSe II, other than the resulting hit of Max aperature, any other "side effects" you'd report? Sounds like a great solution.
And with repose to to the thread, I would love to see a second gen' 45TSe with the same axial rotations as my 24.

None that I know of, though some people have said the 1.4TC MkIII (the one I use) is so close a fit that the rubber ring on the end actually brushes the rear lens element, but nobody has ever reported any damage that I have seen, and I have looked!

The IQ from the 24TS-E MkII and 1.4TC MkIII is much higher than both the 24TS-E MkI alone and the FD 35TS.

Hope this helps.

Is this true for both the 17 and 24mm TS-Es or just the 24mm one?

Which bit!

Both 24TS-E MkII and 17TS-E take the Canon MkI, MkII and MkIII 1.4 and 2X TC's without interference and retain full tilt and shift function. I haven't seen anybody say the 17 has as close a fit as the 24, I use the 17 and 1.4 TC MkIII all the time and infrequently with the 2X TC MkII.

The IQ from the 17TS-E and 1.4TC MkIII is higher than the 24mm TS-E MkI.

Funnily your greens and reds are obviously more saturated in the second picture, which is apparent on the background bricks and moss ! This is more in line with the theory of ETTR.
So we are speaking of a major imbalance in the treatment of the components.
Maybe your software is playing havoc with colours, trying to compensate for a known colour shift of the sensor in low light, but applying it in a range where there is no sensor coor shift due to the overexposure ? Just a wild guess...

I think we have a different understanding of the word saturated. If you put a colour picker on the reds or greens they are more saturated in the top picture in all three sets. The 'correct' exposure is giving more detail and saturation than the severely overexposed image.

Would anyone like to see a tripod collar included in the new designs?

I wouldn't, front movements are infinitely more powerful than rear movements and most of the collar designs convert the lens to a rear movement camera. The oft talked about parallax 'issue' is, really, a non issue talked about by those that don't actually do shift stitching and on the very rare occasions it might impact the image is simple to negate. Even the most often linked article pointing out the 'issue' is a bit of a fake, the example they use is not actually from a 135 format camera!

I'm interested in a Schneider 50 PC-TS but that is a good point; it comes with a collar with an integral ARCA-Swiss dovetail but I'm suddenly not sure how it attaches.  Thanks!

Jim

I have been crucified by people here before for pointing that out, and in the ad for the Schneider they have it on a regular ballhead, about as inappropriate as you can get! If you used it with a really nice geared head, like an Arca-Swiss D4, or Arca Cube, which is the kind of thing Schneider owners should have anyway, then it makes a bit more sense, but to mount it on a ballhead is ridiculous.

If you mounted either the camera or lens on a really nicely marked geared head then you could effectively have front and rear movements with just one set of movements, which is kind of cool, but a big investment for 135 format work (I'd love a D4 though!). Also you can give some thought into landscape or portrait format, with a lens mount system vertical shift stitching is easier than with a camera mount, but it still isn't difficult. On balance I thing the camera mount is a much better solution.

Business of Photography/Videography / Re: The Pros or The Enthusiasts?
« on: January 23, 2015, 03:15:08 PM »
I am a Pro, that is, I earn all my income (nearly) from photography. As always Thom hits quite a few nails on the head, there are more than a couple of keen enthusiasts at my camera club (I have never been too self important to be in the local camera club) with much bigger investments in gear than me, and the rate that they turn it over for newer stuff never ceases to amaze me.

I am gently leveraging into spheres that are still strong, and a few are actually growing, but the entire photographers business model has been in a state of flux for years and hasn't leveled out yet, and probably never will to the degree that it had for generations.

But the truth is that clients that value results gravitate towards pros that can deliver, it is not about the gear (most of the time) it is about the consistency of the output. I recently did a 6 day trip to the Caribbean to shoot three villas, I was given two days at each location and it rained for three days, and I lost the batteries for my one camera before I even got there! But I delivered and the images were good enough to spearhead a new advertising campaign over and above the actual reason for the shoots. Now I am no big shot, indeed I freely admit to being an awful businessman, but my ability to deliver in adverse conditions rises me above the level of those enthusiasts who don't want the stress or have the aptitude for that kind of pressure.

-White balance is not subjective.  It's either correct or not.  It is a term specifically related to the rendition of colour temperature.

-What you do with that file afterwards is your call.  Totally subjectively.  Just don 't confuse the wb slider with the hue slider.

You are the one trying to argue semantics, and if you had read my post properly once then you would have realised we are saying exactly the same thing. When I said WB is subjective, it was in the context of output WB, and that is exactly what you are saying, but as always people read the headlines and not the context. 'Correct'-'True' are the same thing, as are 'afterwards' and 'in post'.

Where we differ is in the importance of getting a 'neutral' file to start with. I don't bother, I shoot everything in RAW with WB set to 5,500 ºK, I find this the easiest to deal with and as there is zero reduction in IQ to changing WB in post I have better things to do. If I am concerned about the lighting I will shoot a Passport reference image every now and again to aid my subjective output, but that really is more if I am worried about metamerism, not so much my subjective output WB. 

As for the Hue slider, generally you cannot get a 'Correct'-'True' WB value without the Hue slider, they are x and y axis of a neutral WB.

Lenses / Re: 17-40 ---> 16-35 f4
« on: January 22, 2015, 06:10:31 PM »
I use the $2,000+ 17TS-E almost every day, it is lauded as the best ultra wide lens made by Canon, I recently got a new 16-35 f4 IS for $999. At 17mm the zoom has every bit as much resolution as my TS-E and the contrast is much better.

The 16-35 f4 IS is a very very good lens with sharpness and contrast that rivals the very best available, throw in IS, the 77mm filter thread, and the keen price, I am more than happy with the purchase.

i will be getting the 17TSE I know its a super good glass but since you own it is the 16-35 f4 a better buy. I will not be switching a prime for a zoom thou.

They are very different lenses that do different jobs, but as a 17mm 'prime' the 16-35 f4 IS beats the pants off the 17TS-E. Of course if you need tilts and/or shifts then the 16-35 is useless!

After selling my 16-35 f2.8 MkI and using the 17TS-E as happily as I was I wasn't actually planning on replacing my ultrawide zoom, but after seeing it on CPW for $999 I thought I'd give it a go and I am very happy that I did, the IQ from it is staggeringly good and the functionality with the zoom, weatherproofing, AF, IS etc just makes it a supremely good package. I know it is really the 17-40 replacement, and as such it is a large cost increase, but to my mind it is worth every penny and some.

The 17TS-E does stuff the 16-35 never will, but unless you really need that functionality then the zoom is a vastly better buy. And unless you must have the 17 fov I'd recommend the 24TS-E over the 17 any day.

That is not to say that an image cannot be enhanced by some colour grading,  it absolutely can, but for me the best starting point is a neutral raw file.
Is there such a thing as a "neutral raw file"?  I had understood that in-camera white balance settings are only applied during the conversion to JPG and that RAW is RAW.  But, RAW files do include a thumbnail JPG which will reflect the WB settings (primarily for the LCD).

You are right, RAW files do not contain a setting to make the WB 'neutral', they have a tag to tell the rendering program what WB was used or chosen, but that is a completely different thing.

On another note, whilst Tinky took exception to the way he read my comment, regarding WB we are actually on the same page, nearly. There is a 'correct' WB setting, and that is what I called 'true' WB, that is one where blacks, whites and greys are rendered neutral, he then said that file can be 'enhanced via grading' in post, which is entirely subjective, whereas I just used the term 'subjective'. Rendering blacks, whites and greys as neutral is not subjective, processing a file to actually convey the scene in a realistically atmospheric manner is (and we do that far more often than process for 'neutral'). You do not have to do the first before doing the second.
