( such as A Hasselblad or Mamiya 645 or Pentax) can be attached to this tripod. However, even though this is a great medium duty tripod, to put that amount weight on top might make it a little unstable. Now if you’re anchored on good solid ground, with little to no wind this tripod will most likely work well. Just don’t walk away if conditions are not optional. Have fun and enjoy your photo adventure. 

Your Nikon lenses will mount to the XT3. Adjust aperture with the adapter. Manually focus lens. 

For heavy medium format lenses like telephoto lens, we suggest to use with a telephoto bracket and a tripod to balance its weight when shoot

 

1. Adapting APS-frame lens to full-frame camera, it may generate vignetting, some cameras could correct it by adjust APSC, please contact us and provide your lens&camera model to check the way to correct it.
2. Adapting full-frame lens to APS-frame camera (i.e: large format to medium format, medium format to 35mm, 35mm to micro 4/3) provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle. and it will magnify the focal length by 1.6 on Canon, 1.5 on Nikon and Sony，2.0 on M4/3 camera.
