Pablete Posted May 20, 2021 Share #1  Posted May 20, 2021 Advertisement (gone after registration) Hi all! First of all, I'm a newbie in digital Leica, only shoot film with my M6 for a few years. I've purchased a lovely 240 with the Summilux 35mm 1.4 ASPH FLE version and I noticed too much vignetting in some images. Is this normal? I guess some is wrong in that configuration, lens is in mint condition and same body with other 50mm lens, for example Summmicron or Zeiss planar ZM, not happened. I've tried some differents configuration with Jpegs, spot metering, only DNG, DNG + fine Jpegs, etc with same results. Thanks in advance... Attahc some examples at f2 and f1.4.  Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Advertisement Posted May 20, 2021 Posted May 20, 2021 Hi Pablete, Take a look here Any problem with my M240 + Summilux 35mm 1.4 ASPH FLE? (strong vignetting). I'm sure you'll find what you were looking for!
jaapv Posted May 20, 2021 Share #2  Posted May 20, 2021 Yes, the lens does have vignetting, especially at 1.4 (which is quite normal for this type of lens) but normally the in-camera profile will iron this out. Do you have lens recognition switched on? In general: the shorter the focal length, the more vignetting. So it is not surprising that you 50 mm lenses are less pronounced.    Welcome, dear visitor!

Yeap, but I've had some 1.4s and 1.2s but I expected that to be a summilux asph and modern version, have less vignetting, even at 2.8 is very noticeable Link to post Share on other sites More sharing options...
jaapv Posted May 20, 2021 Share #6 Â Posted May 20, 2021 Vignetting is optical, and depends on the size of the lens. If it must be constructed small, because of the view-rangefinder, there is no other compromise. If Leica had chosen for less vignetting, the lens would have been larger. No matter, it is the easiest thing in the world to correct in postprocessing. If you look at the graph, it is still 50% at 2.8. 1 Link to post Share on other sites More sharing options...
evikne Posted May 20, 2021 Share #7  Posted May 20, 2021 Advertisement (gone after registration) https://www.kenrockwell.com/leica/35mm-f14-floating-element.htm#fo This is normal. My copy behaves the same way. I've made some presets in LR with different amount of de-vignetting to fix this even more easily with one click. 1 Link to post Share on other sites More sharing options...
Casey Jefferson Posted May 20, 2021 Share #8 Â Posted May 20, 2021 (edited) Typical example of camera not recognizing the lens 6bit code, see the color shift on corners and edges. First check if lens detection is set to auto. If it is, it could be the 6bit reader isn't clean or the lens 6bit code need some cleaning. If the lens is in mint condition, it could be the camera problem? Worst case you just need to remember to manual select the correct profile in camera whenever you mount the lens.

jaapv Posted May 20, 2021 Share #9 Â Posted May 20, 2021 That could be exacerbating the issue. Does the lens show up in EXIF? Is lens recognition turned on? Link to post Share on other sites More sharing options...

Weird, all FLE should come with coding. Yours probably an older 35mm 1.4 ASPH (non-FLE). Set lens detection to manual and choose the correct lens. 1 1 Link to post Share on other sites More sharing options...

M11 for me Posted May 20, 2021 Share #14  Posted May 20, 2021 All these short posts have the tremendous advantage that I have to read very little here. On the other hand I still have no answers to the most simple questions asked here to clarify what lens you have  🤢 1 Link to post Share on other sites More sharing options...

As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! Which of these do you have? FLE (11663) to the left, pre-FLE (11874) to the right. All M lenses produced after July 2006 are 6-bit coded. The FLE was introduced in 2010. So if it's not 6-bit coded, you probably have the pre-FLE, or ASPH v1.

jaeger Posted June 10, 2021 Share #19  Posted June 10, 2021 The ASPH is such a lovely lens. The focus shift bothers me more then vignetting. Link to post Share on other sites More sharing options...
