I managed to figure it out. The aperture ring on the lens has to be fixed at F22 and the control will be from the camera setting. This aperture ring is for manual setting should I add an extension tube with no electrical contacts. Please tell me if I got this wrong.
I will be trying out the lens tomorrow. While we are at lenses. I am looking into replacing my existing lenses and wish to get some advices.
1st, I am thinking of replacing my kit lens (18-105 mm) with either the Toknia 11-16 mm or the Sigma 17-55 mm. I think I may need both but should be able to live with the 11-16 mm first.
2nd, I would like to change my 70-300 to 70-200 f2.8. I am not shooting zoom much and I think 200 is good for DX camera. Even if I decide to shoot further, adding an extension tube and bring up the F2.8 to 4 is still reasonable.
At the end of the day, I will end up with Toknia 11-16, Sigma 17-55, Nikon 50 and Sigma 70-200.
What do you guys think and would you consider what I am thinking? I think this Nikon 50 mm, f1.8 is something you guys would have considered if you have my current set up.
