jamriman Posted December 16, 2011 Share #1 Â Posted December 16, 2011 Advertisement (gone after registration) Holiday Greetings! I'm not sure if my lens has an issue with the aperture lock. When I extend the barrel from the collapsed position it doesn't seem to lock tight enough into place. When I change the aperture the neck of the lens moves out of the locked state and rotates as if to be collapsed. I hope I am explaining this sufficiently. Many thanks for any opinions or suggestions.

algrove Posted December 16, 2011 Share #2 Â Posted December 16, 2011 FWIW, I just took my 90 macro out and as you must know you can lock it for macro shots or 180 degrees around you can lock it as a normal 90. In both cases it locked to the left. After locking it does not move when rotating the f stop. Â There is a small detent feeling when rotating the lens to the right in order to use macro or normal. Once I pass the detent then I rotate left to lock it. Hard to pit into words. Â Does this sound like what you experience? Link to post Share on other sites More sharing options...

I don't have lens with me now but as far as I know it can only be used with the neck extended for normal 90 and with the adapter for macro. Maybe I just don't know how to use it properly? I'll play with it when I get home. Link to post Share on other sites More sharing options...

It is a very nifty lens and so small to carry around when collapsed. Â The neck is extended for either way of shooting. Correct you need it extended and rotated to the macro side and the adapter for shooting macro. I really like using it in macro. Link to post Share on other sites More sharing options...

In both cases it locked to the left.... Never seen this this so far but i may be wrong as i rarely use the goggles. AFAIK the barrel itself (the 'tube') can only be locked to the right. This must be done firmly though so perhaps the OP did not turn the barrel far enough to the right. Link to post Share on other sites More sharing options...
tobey bilek Posted December 16, 2011 Share #6 Â Posted December 16, 2011 It locks clockwise or to the right when viewed into the lens from subject position. Â When the close up eyes are on the camera, the lens must be rotated upside down so you see the correct focusing scale, but the tube still locks clockwise. Â Changing aperture does not unlock the tube if properly locked. Link to post Share on other sites More sharing options...

I only found out after using the lens for a while that true locking requires more force than I had anticipated, read was willing to apply to a new lens.

algrove Posted December 16, 2011 Share #8 Â Posted December 16, 2011 I now realize in post #2 above, I should have specified that when rotating the lens I am holding the camera with the lens facing away from me and looking down at the lens from above. Â Does that now sound right to everyone? Link to post Share on other sites More sharing options...
