Harryup Posted November 6, 2013 Share #1 Posted November 6, 2013 Advertisement (gone after registration) I'm using a Nex-7 and M5 together with 35/1.4FLE and WATE. When using theNex and the WATE I'm using no filters and having no problems but with the Summilux I'm using a Leica UV-filter and getting some blue rings coming from reflections between the filter and front lens. Especially when shooting in dark scenes and there are light sources outside of the actual coverage of the lens. Is the original square lens hood sufficient? Any alternatives? Have anyone seen the same problem with any Leica Digital M's? Without the filters I need to point the camera into the light source to get a very very vague symptom of the problem. Thanks in advance Harry Link to post Share on other sites More sharing options...

matlep Posted November 6, 2013 Share #2 Posted November 6, 2013 UV-Filters in night scenes is a problem on all digital cameras. The light bounces of the sensor cover glass, back on the filter and then back again. Best is to not use filters at all when shooting at night.

jankap Posted November 7, 2013 Share #3 Posted November 7, 2013 Why do you use a filter for the lux and not for the wate? Why do you want to use an UV filter in the night? Jan Link to post Share on other sites More sharing options...
Harryup Posted November 7, 2013 Author Share #4 Posted November 7, 2013 Just using the filter for protection and because I have never had the problem with the M5. I have never had the problem with min Nikon DSLR neither with 35mm lenses. But the new square lens hood could maybe been a bit longer without interfering? How severe is the problem with a 240 since I will order one later? /Harry Link to post Share on other sites More sharing options...
earleygallery Posted November 7, 2013 Share #5 Posted November 7, 2013 As said this will happen with any digital camera, it's simply a reflection from the sensor. It can happen without a filter too! Maybe it's less of a problem on a DSLR because the sensor is further away typically, but it does still happen. The solution is to remove your filter when using the camera in such circumstances.

I don't want to start the protection filter wars again, but one should remove them in high flare risk situations. A solid lens hood is all the protection you need anyway.

Mike Rawcs Posted November 17, 2013 Share #7 Posted November 17, 2013 Advertisement (gone after registration) I have this lens and I too get reflections from the Leica U.V. filter in dark scenes with light sources but I'm using a (film) MP (i.e. no sensor). A quick test shows the UV filter is responsible for the reflections. Link to post Share on other sites More sharing options...
Mike Rawcs Posted November 17, 2013 Share #8 Posted November 17, 2013 I should clarify that I have seen this with other Leica lenses: not just the 35mm FLE Mike. Link to post Share on other sites More sharing options...
gravastar Posted November 17, 2013 Share #9 Posted November 17, 2013 In practice I've found both Sigma EX DC and Hoya HD2 filters to have lower reflections than the Leica ones, they are true broadband multicoated. I have a Sigma EX DC on the 35mm FLE. Bob. Link to post Share on other sites More sharing options...
Harryup Posted November 18, 2013 Author Share #10 Posted November 18, 2013 Thanks for responding. Will try that filter. Harry Link to post Share on other sites More sharing options...
Peter Branch Posted November 19, 2013 Share #11 Posted November 19, 2013 In practice I've found both Sigma EX DC and Hoya HD2 filters to have lower reflections than the Leica ones, they are true broadband multicoated. I have a Sigma EX DC on the 35mm FLE. Bob. I’m confused. According to the Hoya web site here in the UK there is no such thing as an HD2 filter moreover the filters in their HD series are not available in sizes below 52mm. However a Hoya 49mm HD2 UV Filters is apparently available from B&H in the US at $62.90 (USD). Link to post Share on other sites More sharing options...
Guest borge Posted November 19, 2013 Share #12 Posted November 19, 2013 Don't use any filters when shooting during night time. You WILL get reflections no matter what with a filter attached during shooting in very dim light or dark scenes with street lights and all types of strong light sources all over the place that you can't control. Even the best of the best filters with 0.1% reflection rate WILL cause reflections in these conditions. This includes the Hoya HD series and B+W XS-Pro Nano MRC series filters. I'm talking from a lot of frustrating experience and wasted money on filters. Link to post Share on other sites More sharing options...
