"Black Spot" inside 02 Zoom?

Got an 02 Standard Zoom today. Just wondering if this is considered "normal" or if my lens needs to go back...

(And just to clarify, that isn't a shadow. Light has no impact on it, and it's always in the same place. Also, the internal shutter seems to be at the same point in the lens, but seems to work fine.)

I just checked mine and lo-and-behold it has precisely the same arched area on the side.

Thanks for checking! Well, I guess that's reassuring... might be some kind of "handle" for the assembly of the shutter/ aperture in the lens. Will be thoroughly testing the 02 out to make sure I have a "good one" as well (but so far, it is quite sharp at 15mm!).

No problem. I have it with me now that I have a case that is small but holds the Q, 01, 02, & 03 plus batteries and viewfinder.

Is it possible that it is the ND filter and it slides down fully when the setting is turned on in camera?

Ding ding ding! You win the prize, sunny16. It is the ND filter! I just tested it, and sure enough it slides over when you half-press the shutter...


I just realized that these lenses will be crazy-impossible to adapt to other cameras in the future. They have their own firmware, built-in leaf shutters, built-in ND filters, focus-by-wire... really a lot going on inside these silvery plastic shells!

Don't bet on it panoguy. A 3rd party adapter was introduced that allows Canon EOS lenses to function on Sony NEX cameras including aperture, which is motorized, and autofocus!!!
thanks

I feel both clueless and delightfully surprised -- these things have real ND filters built in? I was just assuming the camera's ND function was some digital trickery to lower sensitivity.

So, quick check and this seems to be a two-stop filter in both the 01 and 02. Amazing!

Oh, I'm not betting on anything, but there will need to be a new (smaller) entry into this table for it to happen.

Not at all, though that's one way. But having room for the entire mount recessed inside the native mount is also perfectly possible. (C mount adapters for m4/3 for example.)
