Is there much difference between using native versus M lenses on the CL?

I think the important question is whether the “effect” is reproducible all the time for a given lens+settings. Jaap’s comment above seem to suggest that it is not always and shows up only on a certain angle. Is it so?

 

Flare depends on angle of view for sure but i don't see how a lens like the ZM 50/1.5 could make disappear reflections caused by the sensor. I'm no techie at all though.

I would suppose that the configuration of the last lens element is decisive.

OK, With the sun in the center of open sky, this "day for night" shot gives me a few blobs on the M10 with the same 24/2.8-asph @ f/16, but nothing like the pattern of blobs from the CL's sensor:

Enough.  מספיק  No mas!

...... but previous Leica's are not mirrorless ...... 

Actually, all but the S line of current Leicas ARE mirrorless...

Lower right hand corner?

Lower right hand corner?

There's some diaphragm rays from the sunstar, which are erratic, suggesting that the aperture ring consists of curved segments.  There's a real streak heading up and left along one of those rays, and an image of the sun reflected back in the middle right side of the image.  And finally some bright spots of light through the foliage in the lower right corner.  I think the last are real.  That tree is not very thick.

I don't do much of this shooting, but here is one using the 18-56 with B+W 007 filter on the CL. I can't find much to complain of. (Except that the forum software somehow destroyed microcontrast.)

And here we have one that shows sunstars on reflections (albeit just behind the plane of focus)

Again 18-56, 007 filter

Not bright enough i suspect. Problems seem to come from strong light sources at around f/16.

Well, f16 is something I wouldn't use at all, especially on smaller format sensors. It gives all kinds of nasties.

Scott's pics above were shot at f/16 reason why i did my tests at f/16 as well but other comparos can be made at other apertures i guess.

That's interesting. Bit off topic so do move if you think appropriate but I wonder if the full range on the TL lenses is useable without performance issues? - I only have the 23mm Summicron TL and as I use it more I find most of the shots I'm happiest with are taken between f4 and f11

On APS-C f 16 is sure to run into diffraction problems - personally I even avoid f 11 on the CL.

In good light, I leave everything set for f/5.6, go to f/8 for a little more depth of field, and switch to working from widest aperture or maybe 2.0 with some stop-down for extra depth of field in weak light.  And I don't point my camera at the sun if I can help it.  So it took some effort to make the CL misbehave, and a serious effort to get anything like that from the M's.

I use smaller aperture with Sun in the frame to get good sunstar.

No real issue here on M10. Lifting shadows with Sunstar in the picture does reveal many artifacts that are usually hidden in the darker areas. My understanding is that for CL (I don't have one, I am just reading this thread) the flare artifacts (regularly spaced circles) were visible without lifting shadows. It was illustrated in post #11.

 

I will add that I do have enough experience on Sony APS-C sensor with M lenses and I haven't seen anything like this. If these flare artifacts are easy to be provoked then I will cross out CL from my future list.

Don't take this as trolling because it's not meant to be.  Is it just me or has this thread (which I've just read front to back) managed to exemplify that saying about the two kinds of photo gearheads: those who figure out what gear can do for them and those who figure out what it can't.  What's been demonstrated?  That torture-testing different lenses on a CL produces flare in certain cases.  Sheesh, I can make my Lux 50 flare like fireworks on multiple bodies.  So what?  Anybody able to offer samples of CL photos under reasonable conditions taken with M v TL lenses that demonstrate how they might render differently?

I agree that the thread got off-topic, driven by the feeling that "someone is WRONG on the Internet!!," as a New Yorker cartoon once captured the situation.  What some didn't seem to grasp is that the flare pattern on the CL, seen with several different lenses, was not just due to internal reflections inside a lens, but included a rectangular pattern of red blobs created by a back reflection off the sensor, not seen from the sensors of other cameras.

 

Back to the topic of M vs CL lenses on the CL.  My current example is the occasionally magical M 24/2.8-asph, which I have been using instead of the perfectly competent CL 23.  Here's what it can do (has been posted in the image thread previously):

Thanks, I get it.  Valuable to know if one is going to be shooting the CL directly into the sun wanting "creative" flare that the sensor reflection spoils.
