SLT or Mirrorless and Tilt effect

[Dr. Harout]

I didn't know where exactly to point this question, so decided to put it here as it is related more to SLT/Mirrorless than anything else.

Since SLT/Mirrorless have peeking ability and WYSIWYG, then using a Tilt-shift lens would give you an immediate result in your EVF/LCD (what a dumb question )... But what is actually happening with a T-S lens? (no need to explain)...

What I am getting at, is it possible to have a tilt effect with the sensor (shift is not possible, I guess)? That is, what if we could control a slight angle deviation of the sensor from its initial plane, regarding the optical axis. And you could obviously visualize it in your EVF.

Just thinking...

I would imagine Doc that tilting the sensor would just make part of the image oof, maybe even all of it, the uncorrected perspective coming from a lens would remain as it was except now it would be oof as well. (that's my guess)

Yes. You can see the effect and the peeking will show you exactly where the sharpest area is -well, exactly... there is some depth of field involved...

I believe you don't have enough room (or, phrase it in a different way, you'll need much more room) in order to tilt/shift the sensor in a fashion that you get the effect -and not just a "misaligned sensor" image.
Keep in mind that on a field camera you can pivot front (lens) and back (film) in order to get the miniature effect, or the straight lines everybody dreams about.

Doc, yes, it would work. Same effect as tilting the lens except that it doesn't require the lens to have an extended view-angle.

Greg, you tilt the lens or back (sensor) to compensate for tilted subjects ie tall buildings and such.

As Pako says - tilting the film plane was how this effect started on Large format etc. DK has a great article about this in the latest issue of CameraCraft. (Perhaps this is what started you thinking, Doc?)

I've read more reviews of the new Samyang 24 TS lens. Seems to be ok once you stop down to f/8, but overall not up to the same level as the Canon equivalent. It is several times cheaper of course! Not convinced that I want this lens yet

don't Pentax already have something like this (that's how their astro-tracker works)?

Doc,

Tilting or shifting the sensor would be the same thing as doing it to the back of a view camera.

Find some old articles on view cameras and look at all the illustrations on how that effects the final photo. It's really just the same thing with a sensor, except that your tile is digital and not physical (or as good)! STILL can't beat a good view camera!

I still don’t think it would be a marvelous plan, a view camera doesn’t have an SLT mirror in between the lens and the film/sensor. (it would be interesting to find out though)
