wide.... I mean WIDE!

[fmo]

... but which will cover the top of the world's tallest building?...

from which distance?

from which distance?

From 300Km...that's a long lens

Since the title is    "wide.... I mean WIDE"    I thought to react.

120x100 degrees undistorted with the 14-24mm Nikkor- 3 images

I am using a nikon D3x for architecture and also the three PCE Lenses Nikon recently made.

Canon just put out two new wideangle TS lenses that seem to be at least as good as the Nikkors.

Especially I was intrigued by the 17mm Lens - Sometimes the view just cannot be wide enough. (I would prefer it without a tilt feature)
The samples I saw on internet showed however a lot of -over the top- perspectives- It showed the end of what is 'realistic'.

Somedays ago I discovered that with my 14-24mm nikkor zoom used at 14mm i can make 'realistic' photograps of 120x100 degrees ( 90 is round the corner)  with straight lines using three images shot in portrait mode.
Photoshop connected the three images for me...
To my suprise I got a 48megapixel image that really looks great. The perspective has to be simple- than it still works - it is About 8000x6000pixel
The sides are streched off course but still the quality is amazing.

It only takes a little attribute from Really Right Stuff to shoot the three image  panorama. Distortions of the 14mm  are corrected with PT-lens. So i concluded that I do not need to carry around an extra TS/ PCE lens on my back- it is heavy enough.

The shot below I made to see if it will turn up realistic or not. The shot needed more view than the 14mm could give in one shot.
I think I cut some of the sides but than it is OK.

Very interesting... after hearing how many of the mfdb shooters carry dslr kits with t/s lenses as backup or for quick shots, it made me think about buying the PCe's and carrying my D3 more regularly.  It bothered me, though, that 24mm would be the widest so maybe I will just get an ultrawide prime and stitch/correct perspective on those very rare occasions.

Just a short info from the "work in Progress" Hartblei Cam.
I did some shootings yesterday, besides the lots of demoes on the recent canon promo show 2009 germany.
It appears that the Canon 17TS is capable to fully shift 12 mm on our Hartblei Cam UP AND DOWN. Now that would add 24mm of Image height to a P45+ (which I use for testing).
As the normal unshifted image angle is already 125 degr. (diag.) this should give a stitched something close to (I know this sounds really crazy now) 150 degr...........
If you step this down to at least f14 or f16 even the corners are "usable" although I know for the pixel peepers who will start reproing Siemensstars immediately this may not be an option.
On the other hand it´s the only lens on the planet which goes that far.

attached here are 2 samples the Canon TS 17mm shifted up about 9mm (!!!) and the Canon TS 24mm straight both from a P45+ downsampled.
The pics are not very neat or designed, just some demo shots from the Canon tour, but I will upload soon some of the full phaseOne P45+ files I did yesterday night.

"The 17mm exhibits virtually no barrel distortion, maybe a very slight adjustment needed."

the 17 exhibits a lot of moustache distortion, while the new 24 is really ggod !

How about custom made body for your MFDB?

I will try to make Canon EF lens version, but I don't need more wideangle lens now.(PC nikkor 28mm)

It's very cheaper than Hartblei cam. below US$2K?

and If you use wideangle, focusing is not important becuase of large DOF.

Generally I've shot HC35mm but, I used my custom 28mm body for special interior shot.

Whenever shot, I set focusing to infinity and F8~11.



now, I'm test my CONTAX carl zeiss 85mm F1.4 T*lens with P45 back.

modified for nikon F mounts. contax 85mm has about 59~60mm image circle. so a little, very little vignetts occured.

Image quality is excellent, is comparable HC80mm.

but flange distance problem, It can't focusing infinity now. but about 0.5~10m focusing well. It's enough to my cases.



When shoot F1.4, It has wonderful depth of field view.

I will post detailed pictures with 85mm F1.4 / P45.

Your copy exhibits a lot of moustache distortion? Can you post images showing this?

Its unlikely that there will be any signficant sample variation for distortion.

That's why I'd like to see his images showing said distortion.

Well the 17TS and 24TS are the only two lenses that PT lens state there is no need to correct.

You might want to take your sample back to Canon.

Cheers
