agree..  just bunged the numbers through cambridge in colours diffraction limit calculator and it suggests around 1Gpix required to fully resolve a nifty fifty wide open..  (if it's diffraction limited that is)

LOL. Now go and shoot a resolution chart with that nifty fifty wide open and tell me what you are getting off center.............................

You know, I think you'd mentioned the Tables when I started off with the TS-E and then I completely forgot about it and was making my life difficult....
Thanks a bunch!

No problem, it is easy to forget stuff like this.

Here is the one I use from Keith Cooper, a member here, over at his site Northlight Images http://www.northlight-images.co.uk/article_pages/using_tilt.html

One thing they could do to greatly improve the functionality of the TS lenses is gear the tilt to a much finer degree, I rarely want 8º but would love much finer control between 0º and 4º's.

Lenses / Re: Prime vs zoom for landscape?
« on: Today at 12:45:14 PM »
For landscape use the EF 16-35mm f/4L IS is pretty hard to beat.  It has some of the best IQ Canon offers (including their primes) if not the best for landscape...

Did you ever use the TS-E 17mm and TS-E 24 II before making such a claim? I ask because I never had the chance to test the EF 16-35mm f/4L IS. But I know these two TS-E lenses pretty well...

I did, the 16-35 f4 IS zoom is every bit as sharp and has much more contrast especially at the edges and corners at 16mm than the 17 TS-E, the zoom does have noticeable barrel distortion at 16mm, when the 17TS-E has none, but it is easily corrected in post without a significant impact on IQ. The zoom doesn't have movements but it does go to 35........

I own both and would really struggle to make a choice of one or the other unless I had a specific shoot to do and IQ would not be the determining factor, ever.

To follow up earlier post ...  right on target, so many DSLR's out in an audience, and all clicking away, at least one or two are bound to "get lucky" and hit a 'reasonably decent shot', and offer it for peanuts or free.   

No no no no no, that is absolutely not what this is about. It is about making some of the best general sports photographers in the world freelancers rather than staffers. It means no more gear budget, no more medical benefit costs, no more post processing staff and equipment and the office space and cost they incur, no more travel expenses etc etc, it is about cost cutting not about buying the one shot a fan might have, those fans will never get the access and they will never get the releases, heck most high end sports venues have 8" lens limitations.

The same photographers will be shooting the same venues with the same gear, SI will not have any of the costs associated with getting a photographer, or photographic team, to a venue and they will have the ability to buy any freelancers images if they want to.

What will happen is the ex staff photographers won't make as much effort to try new stuff, they will have to concentrate on bankable sale-able images first and foremost because they now have gear budgets, travel costs, and health insurance, to pay out of whatever they can sell on the market.

There are an awful lot of people here who did exactly what I laid out, owned a crop camera and then got a ff one and hardly touched the crop camera again afterwards, virtually every one of them will say they see the difference in their images, if you can't in yours then that is up to you.

The only benefit of APS-C over FF is increased pixel density.

If Canon bring out a FF DSLR with similar pixel density to the 7D2, I wouldn't be surprised to see a bunch of folks sell  their (FF, APS-C) combo and buy a single new camera. The only consideration then would be if the new camera has enough FPS.

I have no intention of getting drawn in to one of your back and forth black holes either dilbert.

But APS-C have more advantages than the spurious pixel density which has been illustrated time and time again to be largely meaningless in real world shooting of same generation sensors. There is the cost advantage, the features advantage (fps, swivel screens etc), the AF area as a percentage of the frame advantage, size advantage, weight advantage etc etc.......

The real competitor for this camera will not be other full frame cameras, but the Pentax 645Z

Not really. Anybody that has owned a crop camera then moved to a ff camera and then left the crop camera to gather dust knows the intrinsic difference that sensor size makes, well that happens again going to medium format digital, throw in the lack of AA filters on medium format and the differences become even bigger.

In the same way that crop  can't ever deliver what ff can (though I am not saying crop cameras are not very good and have several key advantages over ff cameras in specific situations), ff will never be able to deliver what medium format digital can. The point at what each sensor size becomes 'good enough' for each individual is an entirely personal call.

I use a crop camera and a full-frame camera side-by-side all the time.  I just usually use a lens on the crop camera that's one stop faster than the lens on the full-frame camera allowing me to use one stop lower ISO on the crop camera.  The resulting images are virtually indistinguishable from each other.

I don't care what your opinion of the differences are, or are not, as I very clearly said.

You missed the point.  The differences are removed if the smaller sensor shoots at a lower ISO.

A full-frame sensor is like a faster lens.  The difference between 1.6-crop and full-frame is 1 1/3 stops.

I didn't miss your point, I ignored it.

How do you shoot with a lens 1 1/3 stop faster on your crop camera if you are shooting on your ff camera with a 1.2, or a 1.4? How about if you are shooting 2.8 zooms all around? What if you are going big with a 300/400 f2.8 on the ff, or a longer f4?

There are an awful lot of people here who did exactly what I laid out, owned a crop camera and then got a ff one and hardly touched the crop camera again afterwards, virtually every one of them will say they see the difference in their images, if you can't in yours then that is up to you.

Given that many people with FF cameras have a 24-xx L-series zoom...

In my case, I had the 16-35/2.8 II and swapped it for the TS-E 17mm as my ultra wide lens...

Neuro, do you use your TS-E exclusively on a tripod, or do you often find yourself shooting handheld?

Almost always on a tripod, though I have shot handheld a few times with the TS-E 24 (using shift, not tilt).

+1
Can't imagine myself holding that beast of lens+body combo with one hand, in front of my face to use live view, and changing the tilt movements with the other hand.

You don't need to, you can work out the tilt you want before you lift the camera to your eye, the 'J distance' is the key and tilt tables give you the values you need, the shift is easy to do through the viewfinder and focus will follow on from your tilt angle and desired plane of focus angle. It sounds much worse than it is but once you start playing with the TS-E's it becomes second nature.

What do you use your TS-E for?
I have generally don't use wider FoVs than 24mm for landscape and the 17TS-E is great for buildings (outside and inside) and the Rokinon 14 is great for getting really close or small spaces. For that reason, amazing as it is, I haven't been able to justify the 16-35. Since I hope to get into real estate photography, I think the 17mm is one I need to hang on to even for non-entertainment purposes :)

I use it for architecture and real estate, the truth is it is overkill for the vast majority of real estate, but I shoot for developers and high end rental so any of my images can end up in brochures, print, or even as posters.

Though one of my mentors, an awesome leader of his field who was published in glossy magazines with multiple page spreads every month, shot multi million dollar projects with a Sigma 12-24 on his 5D MkII.

It really depends on what kind of 'real estate' work you are intending doing, it sounds silly but it starts to branch out pretty quickly. Regular MLS stuff would be better served with the zoom, and you'd earn the money back faster! But as you get into the higher end with larger spaces and bigger expectations the TS-E's come into their own. For anything architectural, the TS-E's are a necessity as all the other shooters are using them.

For most real estate image buyers drones and video walk throughs are becoming must haves and most shooters would be better off spending the money on a drone rather than a TS-E.

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.

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........
