As you know Tokina launched those three new APS-C E-mount Reflex lenses:
- Tokina 300mm lens at BHphoto, Amazon, Adorama.
- Tokina 600mm lens at BHphoto, Amazon, Adorama.
- Tokina 900mm lens at BHphoto, Amazon, Adorama.
SonyAlphaBlog tested all three of them (Click on the links to read the review):
- The 300mm F7.1 is the champion for the pocket size
- The 600mm f8 is maybe the one with the best sharpness and the best comprise in term of focal length
- The 900mm F11 is much bigger but its magnification (1350mm equivalent) is phenomenal. Unfortunately it is also the less sharp of the 3 , the one most sensitive to wind and difficult to focus
