canon vs sony 7rll for use with canon TS lens

This minute

Im currently using an older nikon d700 and have several of the top lens 16-35, 70-200, 24-70.

Ive recently ventured in architect photography world have some good opportunities. Currently renting a Nikon 24 TS

for one of the projects.

Looking at the sony 7R ll

i like the idea of getting adapter to accept canon TS and my other nikon lens . i'm aware i'd need two adapters.

Does anyone know if there are any limitations to using the adapters with these lenses.

I'm not really in the market to switch out to canon.

thanks for any suggestions.

owen

I use a Novoflex adapter for Nikon lenses (and another for Leica M lenses). The adapter is a metal tube which puts a Nikon lens mount about an inch from the Sony mount. There is no mechanical interference using the Nikon zoom lenses you describe, and I doubt the TS lens would cause any trouble in this respect. Since the ID of the adapter is the same as the ID of the mount, it might cause some vignetting. The Novoflex is machined with knife edges and coated dead black, so the large image circle of the TS lens would probably not result in internal reflections and flare.

 

The Novoflex has a ring to set the aperture by engaging the tab extending from the lens. If the lens has an aperture ring, set the Novoflex to one extreme and set the aperture with the lens. If there is no aperture ring, you can use the Novoflex to roughly adjust the aperture. The throw is only about 1/2", so it's poke and hope territory. There are no contacts to relay information from the lens to the camera in this adapter. There are adapters which work with E lenses, and are compatible with AF-S autofocus.

 

Canon has used electronic aperture settings for years. There are adapters fully compatible with Canon lenses, even autofocus with lenses made since about 2007.

 

There is very little a TS lens can do that Photoshop cannot. Perspective correction is easy, with powerful tools in Photoshop, even Lightroom. Keep the camera level to minimize the loss to cropping pursuant to these corrections. The tilt function for focus can be emulated using focus stacking

I don't own a Sony yet. - Maybe that blog post is helpful for you? To my understanding they say an adapted Sony is less likely to nail focus than a proprietary Canikon? But I'd be more confident about manually focusing a tilt shift lens on the Sony.

You often have to "calibrate" fast or long lenses in a DSLR, because the focus detectors are offset from the film plane. In a Sony, the focus detectors are embedded in the image sensor. Some lens adapters put focus detectors in the adapter itself, along with an image splitter. These must be calibrated, and there is a menu entry in the Sony to do that. That was an issue with Sony/Minolta A-mount lenses, but I haven't heard of it with Canon, or more recently, Nikon AF, but they're not in widespread use.

 

That said, phase detection is a predictive method of focusing, and relies on a chip and lookup table in the lens itself. Stopping down not only increases the DOF, but transitions to contrast detection, which is slower but more accurate. I use the DMF option in single-servo focusing, which reverts to manual focus once the AF thinks it is done. Also, AF does not always select the object you wish to be in focus. You might have to try again, or focus manually.
