Comparison of two tilt-shift lenses: Canon TS-E 90mm (non-L version) and 24mm (non-L version) in UV and IR

[Kai]

Attached I would like to show a few comparison photos with the lenses mentioned in the title.
The images were taken with a modified Canon 6D.
The UV photos were taken through a filter stack ZWB2 with two QB21, the IR photos through an 850 nm filter.

The solar spectrum (slit, DVD grating) was recorded with both lenses through the filter stack. The UV reach and transmission are not particularly good, but allow for a weak yellow-blue differentiation with WB against PTFE.

The images were taken with a clear lens tilt at f 8.0 (both lenses).
The 90 lens is more powerful. The 24 is not very suitable because of the hot spot in the UV. In IR it shows less contrast than the 90.

 

At first the TS-E 90 mm:
 

 

 

 

Second the TS-E 24 mm:

 

 

 

 

 

 

Has anyone tried a tilt/shift adapter on a mirrorless lens with non-tilt-shift lenses?

I don't think you can use a mirrorless designed lens on a tilt shift adapter. 

I have a Nikon F-mount to m43rds tilt-shift adapter.  It will only work on my Olympus Pen-f and Panasonic GM5 cameras, as they don't have false penta prisms blocking the mount. Neither of these cameras are converted. Both are stock. 

I also have a Pentax 645 to gfx tilt shift adapter,  but I haven't used it yet on my 720nm converter 50R camera. I have the Pentax 35mm, 75mm and 120mm lenses.  I can also mount pentacon six lenses and maybe the Nikkor 105mm El f5.6 lens on it, with adapters. 

I don't have a full spectrum converted gfx camera.

I used the TS-E 90/2.8 on an R5 for UV pictures a few times, tilting down.  Occasionally, light leaked through the tilt-shift juncture, so I wrapped foil around it.  I wonder whether the hotspot with the TS-E 24mm that you mentioned results from light leak.

@ dabateman: I looked in vain for a tilt-shift adapter with an EF to RF function.
                         Maybe something can be modified/adapted?

 

@Ming: Good point!
              I'll check (as soon as the sun is visible here again ;)

Do you mean like this one:

You will not get electronic contacts with a tilt-shift adapter,  so might be better in Nikon F-mount

I have Canon TS-E 17/4 which has electronic aperture control and it works OK on GFX, I'm using Viltrox EF-GFX adapter pro. This + STC Fuji GFX clip-in 850 nm filter gives me equivalent of 13.5 mm wide angle on FF with infrared and has full aperture control.

 

[Unscenerie]

I have a Fotodiox Canon EF to Sony E shift adapter. I have tried it with my Sony NEX-5N and some accidental full-frame UV lenses, but their corners are too soft and this shows when shifted.

 

I mean, a shifted full-frame lens on an APS-C camera isn't too bad I guess.

 

I have a Pentacon Six lens and thought of adapting it to my FS Sony A7 but I'm not sure it's even worth it because of potentially low UV-transmission of the Pentacon Six lenses.

That looks very good. Thank you very much for the tip!

Such adapters adds some risk for light leakage that might not be seen in VIS. For UV it is magnitudes more sensitive.

The same phenomenon was seen with the built in extension in the Noflexar 35mm.

That is an important point! With the Noflexar 35 mm I even had to observe this in the VIS...
