DRabbit Posted May 25, 2010 Share #1 Posted May 25, 2010 Advertisement (gone after registration) This is to questions actually. I noticed yesterday... I had the camera set for aperture priority (aperture dial turned to an f-stop of my choice, shutter dial turned to A)... Yet when I wasn't using the camera but it was on, I heard a "flutter" or light ticking sound from the camera. I looked into the lens and saw that as the light changed, the aperture was automatically opening or closing to adjust. Is this normal? It doesn't seem like the aperture should be adjusting at all if I'm dialed into a specific one I want to use... Also, I notice a ring around the lens that is removable (it quite easily unscrews)... What is the purpose of this? Anyone know? Link to post Share on other sites More sharing options...

leicabrae Posted May 25, 2010 Share #2 Posted May 25, 2010 Hi Amy, On the 'flutter' thing: I've been wondering about that myself. I can't see any reason why it should happen especially when one is in Aperture mode! That is going to shorten the life of the lens, no doubt. I'll email Leica and see if and what they say... Maybe the next firmware will fix it? Rgds, Walter Link to post Share on other sites More sharing options...

In both cameras it doesn't seem to effect performance as far as taking photos and getting the correct exposure, however, like you, I felt it could reduce the life of the lens as well. With the Panasonic, I suppose that isn't as much of an issue for the price paid for the lens... but with the Leica and the fact the lens CANNOT be changed, could it not reduce the life of the camera? I can't imagine why the lens would act this way on either camera with the mode set to Aperture Priority. Link to post Share on other sites More sharing options...

Now please could you explain it to mee, how des the "apperture flutter" shorten the lens life span? By scratching? Link to post Share on other sites More sharing options...
leicabrae Posted May 25, 2010 Share #5 Posted May 25, 2010 Well, the worry is that what's happening is that the aperture blades keep opening and shutting in fairly quick succession as lights conditions change (if I'm keeping the lens uncapped, I'd be walking with the camera pointing downwards while protected in the palm of the hand and the reflection from the ground will vary a lot in light intensity). The blades are a mechanical part and it stands to reason that this 'feature' of the lens might increase wear and tear. I've actually noticed that even the D-Lux 4 does the same thing. The noise is far less noticeable than on the X1 though. However, I have it on good authority (Leica) that this is perfectly normal and won't affect the lifespan of the lens. (which might mean that there are other parts that are forecast to fail earlier than the aperture blades...!) Link to post Share on other sites More sharing options...
vicpeh Posted May 26, 2010 Share #6 Posted May 26, 2010 Actually, every single camera (including all P&S) with live view I have used does this aperture fluttering thing. It's to get a correctly exposed image on the LCD screen. Nothing much to worry about at all. Link to post Share on other sites More sharing options...
DRabbit Posted May 26, 2010 Author Share #7 Posted May 26, 2010 Advertisement (gone after registration) Good to know its nothing to worry about... It certainly hasn't effected performance, it's just mildly annoying (and is on the ep2 as well). Now, does ANYONE know what the ring around the lens is... The one that screws off quite easily???

jsrockit Posted May 26, 2010 Share #9 Posted May 26, 2010 Completely normal and after months of use, you won't even notice it any more. Link to post Share on other sites More sharing options...

h00ligan Posted May 26, 2010 Share #11 Posted May 26, 2010 Some speculation it's potentially for an adapter tube like the dl4/lx3 to enable filters as well. Link to post Share on other sites More sharing options...
