Bower 14mm weird behavior ---SOLVED !!!!

(1/2) > >>

NWPhil:
So finally I got my hands on a bower 14mm,  in preparation to a Canon ef 14mmL II loaner trial.

Sure I was aware that focus and aperture are manual, BUT as I switched the aperture ring back and forth,from 2.8 to 22, no light change did happen.
I tried a few times, and nothing, till I gave the lens a light tap on the side, when the value was at f/22.
The viewfinder did become darker as it should be. I turn the ring to 2.8, and it did become lighter, but as I turn it back to 22, again no light change on the viewfinder
The light tap solved the problem.

No, I am not kidding, but has annyone ever experienced similar situation with this lens ( knock-offs included)?
It seems that the lens has some issues...

Thanks for your feedback

I own the bower (Samyang) 14mm + used with my 550d.

Superb Lens. Always use in AV.

Never had such as issue.

NWPhil:
Thanks
I guess you mean Tv? the manual aperture ring controls the aperture, and is not registered by the camera sensor.
Truelly, you can shoot in manual or shutter speed only.
Thru the viewfinder, does the brightness changes, as you turn the aperture ring in the lens?

Thanks

I am having one of those delivered to me today. If I see such issue, its going straight back for an exchange. I heard of decentering and other such quality issues with some copies of this lens, but nothing like you have described. Sounds like something is causing the aperture blade to be hesitant in opening and closing.

Mt Spokane Photography:
Take it back.  Mine resulted in images with the entire left side smeared.  I've never seen a lens with this poor of quality.  QA is poor, so its hit and miss. 
 
I've seen almost as many complaints as those with praise.
