According to Sonyalpharumors website the NEX-FF photocamera project will come within 2 months. In light of the quality expressed by the Sony RX1®, is there a possibility that - from a technical perspective - the new NEX-FF will impact on Leica affecting the new M240 in terms of overall image quality and sales (being offered at a more affordable price)?
Hello, I'm new to this forum and I'm seeking some experienced advice. I recently purchased a Leitz Summaron 35 f3.5 with goggles from eBay at a very reasonable price - for a reason - the rear element has considerable haze/fog that is noticeable on every image. I've been reading on the web that it is possible to clean the glass and even to DIY it: Removing Haze from Leitz 35mm F/3.5 Summaron Lens - DJCPHOTO.COM Now, I've tried going ahead with the instructions provided by the link above but I'm finding it impossible to remove the rear lens retaining ring. In addition, I have unscrewed the focusing helicoid and I think I have not been able to put it back together correctly. Apart from sending my lens to more competent hands, does anyone have other advice or guidelines for cleaning the lenses (and putting the focusing helicoid back correctly...) myself? Thanks for your time
