  1. Thank you all for your responses.

     

    Since this lens is practically new I'd like to get the element replaced if the cost is reasonable. I've seen a post here dating back to 2001 where someone was inquiring replacing a rear element for a Zeiss/Hasselblad lens and was quoted $177 for the part and IIRC ~$50 for labor. For that particular case the rear most element was part of a group and the entire group was replaced. It looks like the rear element of the 21 Biogon is in it's own group.

     

    I think if the price is in the same ball park(less than $350) IMO it's still worth it to have it fixed. The scratch is small, however relative the SLR lenses the rear element on the Biogon is tiny and since it's so close to the film plane I'm not sure what the impact might be. It is difficult to test since I do not have a baseline to compare to and I do not have a digital M body.

  2. Hi,

     

    I have a ZM Biogon 2.8/21 and the rear element has a very tiny hairline scratch

    on it. I don't know how that got there, maybe accidental contact with the RF

    coupler.

     

    I would like to have the rear element replaced. I have contacted Zeiss Germany

    and they haven't gotten back to me yet.

     

    Does anyone know if Zeiss have any service centers in the US? I understand

    these lenses are made in Japan but so far it seems Zeiss Germany handles repair

    work for them. Anyone here had elements replaced on their Zeiss lenses and can

    shed some light on the ball park cost of such a repair?

     

    TIA

  3. Hi,

     

    I recently purchased a pre-owned 35 Summicron ASPH. I noticed the aperture ring

    needs very little effort to turn as compared to the aperture rings on most pre-G

    series Nikon lenses. This is my very first Leica lens so I have no clue if this

    is normal.

     

    Sometimes when I focus if I am not careful I can accidentally change the

    aperture setting if my fingers touch the aperture ring.

     

    Can someone tell me if this is normal?

     

    TIA

     

    - Daniel
