In-Camera Framing Controls for a7R II

[Eponym]

This high mPix sensor combined with UWA, like the voigtlander 10mm, is just screaming to be used as a virtual shift lens (tilt-shift)

 

Example: The canon 17mm T/S basically has a 10mm angle of view and the photographer is throwing down $2200 just to crop that extreme angle down to 17mm in-camera.

 

I figured if there was an easy to use in-camera framing/cropping controls, you could turn any lens into a virtual shift lens, if you didn't need the whole sensor. Obviously the shifting amount is dependent on how much you're willing to crop, but that would be a user decision. I noticed the Angle Shift add-on for time-lapse allows for framing adjustment, but does anyone know of a way of implementing this feature on stills?

 

I'm well aware of software cropping, but that defeats the purpose of perspective control. I'd also like to know the extent of Sony's SDK to see if I could develop it otherwise.

10mm on APSC rotated to "portrait". All excess

foreground has been cropped off. Nothing high

tech or expensive. Anyone can do it, no special

software etc. 

  

Acoarst a 10mm for an APSC is not pricey and is

not amazing. Putting a 10 on a FF is gonna cost

beaucoup sheckels, but allows dealing with taller

buildings than the one pictured above !   

  

I'm not grasping why you say "I'm well aware of

software cropping, but that defeats the purpose

of perspective control ". Cropping IS perspective

control, and PC lenses are just cropping devices.

You seem to say exactly that ... elsewhere in the

same post. I don't see how either thing "defeats"

the purpose of the other. They can both serve the

same purpose and both get used in tandem when

neither one does the whole job by itself. Since it's

common enuf  to need to use both in tandem, it's

not like a redundancy that needs to be eliminated.

This part here makes sense: "I noticed the Angle Shift add-on for

time-lapse allows for framing adjustment,"  .... cuz video is unlike

still photo. Still photo has the advantage of dealing with a singular

image rather than a stream of thousands of images. It's simpler.

  

Therefore ... this part does not make sense to me:  "does anyone

know of a way of implementing this feature on stills?" 

 

What's with all that jargon ? For stills "in-camera framing/cropping

controls" is not a "feature" or an "add-on". It's just the normal use

of  a still camera. You frame your subject and make an exposure.

If your subject doesn't fill the frame, you crop the excess stuff out

of the frame. Wash-rinse-repeat. No magical dust required. What

am I missing ? What does "implementing this feature" provide that

the ancient "shoot ... then crop as needed" method does not ?

It seems you guys aren't grasping the point of a tilt-shift lens, which isn't exactly the topic I was trying to discuss (please read that discussion here). My simple question was asking how to crop--in camera beyond APS-C mode--and whether or not the Sony SDK can help with that.

 

But if my motivations are important to you, I'm an arch photog. In our world it's 90% required to shoot level. This limitation is freed up somewhat by perspective control. If you're asking why not just do perspective corrections and crop in post, well that's a gambit you bet on without knowing 'exactly' what the final comp will look like. Removing guess work out of thousand-dollar+ shoots is best for consistency and plus if the client is on site your compositions will look twice as good in camera. Hopefully this helps explain how valuable this feature would be for all of us in arch/RE world.
