Nice shots!
Is the Rokinon replacing the Tokina or adding to the collection? Pros and cons of each?
Thanks,
Dennis
The Tokina 11-16 is a DX lens. It will work but only in Crop mode. Which I found is automatic on the D750. You put a DX lens on and the default is to go to the Crop mode on the camera. It you are going to do that then you might as well use the D7100 to shoot. Get more pixels that way.
The Rokinon is a FX lens so you really are shooting at 14mm instead of the 11mm on DX which is an equivalent of 16.5mm . I would not have thought there was that much difference in 14mm and 16.5mm but there is.
I do a lot of interior photos where I need the entire room in 1 shot. The 11-16 would do a pretty good job but the 14mm does it better. Also with the super wide lenses you don't have to worry about focusing the lens. Many of the areas I shoot there is not enough light to see what you are focusing on. I still like to shoot at ISO 100 so I carry a tripod and preset the lens on 7 feet or so and the aperture on f8 and everything from 2 feet to infinity is in focus. That is hard to beat. I think Long exposures tend to give you better color saturation anyway. May be in my head but that is what I tend to see.
