thybo Posted January 20, 2011 Share #1 Posted January 20, 2011 Advertisement (gone after registration) Anybody who can help? Using the X1 together with lens tube (KIWI-LA-49X1) and UV-filter (Tieffen 49mm). The result is rather strange I´ve (tried to) attached 2 pic. to show the difference with/-out using UV filter. Mostly when the pic. has ex. electric lights/lamps in it. I can see that other members had made this solution (tube+filter) so others must have had the same problem ?

prk60091 Posted January 20, 2011 Share #2 Posted January 20, 2011 it looks to me like there is alot of refraction going on with the tube/filter combo (ie light "bouncing" around between the filter and the lens - could be a "cheap" filter although Tiffen filters aren't bad- they aren't of the "best" quality. the "protection" UV filters provide is illusory. the front element of any lens is the least expensive element to replace/repair. I haven't used a UV filter in years- and I havent had any damage to the front element either- I figure the money I have saved in not buying UV filters over the last gazillion lenses on many camera bodies has now paid for that front element if I ever need to have one repaired..... Much better protection is a lens hood. Link to post Share on other sites More sharing options...
Guest Posted January 20, 2011 Share #3 Posted January 20, 2011 i like the protection with a filter,but i think you have to add a hood to protect the large (filter)glass area against reflection.... imo tube+filter+ hood is the best protection and works great in my case. i´m curious ,can you show a pict of your x1 with the kiwitube:rolleyes: Link to post Share on other sites More sharing options...
h00ligan Posted January 20, 2011 Share #4 Posted January 20, 2011 Inexpensive uv filter... not multicoated enough. Very common on all sorts of cameras when shooting with uv filter that isn't properly coated, and sometimes even the god ones at the right angle. Don't use one unless there is uv to kill Link to post Share on other sites More sharing options...

Well the reason using this set-up is primary to protect the whole lens-system. But You have some points there... What would the best UV filter be to You.?

earleygallery Posted January 20, 2011 Share #7 Posted January 20, 2011 Advertisement (gone after registration) This is the simple issue of the light being reflected off the sensor onto the rear of the filter. Buying a more expensive filter isn't going to stop the reflections, you just need to remove the filter when shooting such subjects (assuming you want to keep it on the rest of the time).

What would the best UV filter be to You.? Thanx for response I have used a Heliopan polarizing filter and B&W ND filters in the past- both manufacturers make high quality filters i would assume a UV filter from either of those manufacturers would give you much better quality (also at a higher cost) Link to post Share on other sites More sharing options...

Thanx for respons i think the difference is in the quality difference of the lenses between the dl4 vs the x1 and sensor size Link to post Share on other sites More sharing options...
JeTexas Posted January 20, 2011 Share #10 Posted January 20, 2011 My guess is too much distance between the end of the lens and the filter. It's allowing reflections of either the inside of the hood or the lens itself to bounce back onto the filter. I keep a Tristar UV filter on my Nikon lens all the time, but I don't bother with the X1. I only use an adapter and a circular polarizer when I'm outdoors in daylight. Link to post Share on other sites More sharing options...
andybarton Posted January 21, 2011 Share #11 Posted January 21, 2011 the "protection" UV filters provide is illusory. the front element of any lens is the least expensive element to replace/repair. I have had a lens rendered useless and unrepairable through front element damage. OK, it was a 19mm Elmarit-R, not a cheaper lens on a compact, but it was still a write off. All my lenses (with the exception of a 60 Macro-Elmarit, where the filter would be way too far in front of the lens) sport Leica UV filters on them and will have so long as I use them.

Stefan K Posted January 21, 2011 Share #12 Posted January 21, 2011 I'll second Andy's comment. Also, according to Leica, in the case of the X1 the front element cannot be replaced without replacing the entire lens and sensor module (at a cost of 650 Euro). So while I am not using a filter on my X1, I can see why people might want to. Link to post Share on other sites More sharing options...

thybo Posted January 22, 2011 Author Share #15 Posted January 22, 2011 Well All in all - I just wonder why no one - but me - with the same set-up - has had the same problems ?? Strange .... Thanx for the responds - so far Click Thybo Link to post Share on other sites More sharing options...
h00ligan Posted January 22, 2011 Share #16 Posted January 22, 2011 That's been answered many times. It's the quality of your filter. Buy a b+w and see if the issue exists - if so - return it and you've eliminated one possibility. That said, I can show you the same artifacts from my gf1 with cheap uv filter I forgot to remove when I first bought it. Link to post Share on other sites More sharing options...

The hood will only help when the light source causing reflections is outside the field of view. Link to post Share on other sites More sharing options...
wda Posted January 24, 2011 Share #20 Posted January 24, 2011 I wonder whether the modification is justified? In an attempt to add a filter and hood the whole camera quickly ceases to be a compact camera! With reasonable care it is possible to shield the front of the lens with a hand or other convenient nearby fixture, like a door frame. I seldom suffer from flare and enjoy the compact nature of the X1. Why convert it into something never intended? Link to post Share on other sites More sharing options...
