The O.I.S. drive keeps running, albeit muted and presumably disengaged even when O.I.S. is switched off. I don't think you'll find switching off the OIS makes any difference at all. I find with Panasonic lenses I use and even the SL Summicrons there is a background noise all the time, hoping someone more knowledgeable than me can jump in but I think the noise is more related to the af lens drive, all more battery hungry as you say.

jaapv Posted October 3, 2020 Author Share #122 Posted October 3, 2020 Switching the lens to MF does not make difference. Switching OIS varies the level of noise. 1 Link to post Share on other sites More sharing options...

I wonder if Sigma will release a software update later on to fix this...or if this is a Leica camera update. At any rate, I hope an eventual software update can fix this. 1 Link to post Share on other sites More sharing options...
papimuzo Posted October 4, 2020 Share #124 Posted October 4, 2020 Hello experienced users, I just got this lens. Apparently the CL recognizes it: we can see the text related to the focal range and the aperture range! What it means in term of corrections inside the camera? Just curious, I have not yet used the lens: too heavy without a tripod collar (ordered), I verified only that af is working, at f=100 and f=400. Thanks for clarification. Happy pictures to all.

tommonego@gmail.com Posted October 4, 2020 Share #125 Posted October 4, 2020 I am thinking of this lens, I have a 400 f5.6 Telyt with a Leicavit which for a manual 400 focuses quickly with the CL. But to get the ability to hold it to 1/500 I need a Leica table top tripod as a body brace. The other problem is its closest focus with a Visoflex head is about 12 ft, with out a spacer 30ft which is fine for larger birds, not so great for small birds. I feel the lens is a little better from what I am seeing from the Sigma, but not that much better to overcome draw backs to the Telyt. Then I remember a problem I had with a Sigma lens (28-70 f2.8) back in the late 90s early 2000s where I had to take back then lens 3 times before I had one that would focus with my Nikon. The camera store checked each one and agreed with me, but Sigma wouldn't refund the money, which the store tried to get them to do. So some nasty background with Sigma.

jaapv Posted October 5, 2020 Author Share #126 Posted October 5, 2020 I have the 400/5.6 as well and it is certainly not better than the Sigma. It is fine, albeit "vintage" in the center and barely usable in the corners, reason Leica replaced it by the 6.8. This completely normal for one-element doublet Achromats. The Novoflex triplet Noflexar 400 -T was the best of the Achromats, I really was quite taken by that lens, but still you'll find the Sigma better. Decades of optical development do show.

tommonego@gmail.com Posted October 5, 2020 Share #127 Posted October 5, 2020 (edited) Advertisement (gone after registration) I hadn't noticed the corners, but I am mostly using it on a CL. 😁 But the Sigma is still attractive, nothing wrong with auto focus, OIS and a 100-400 zoom.

jaapv Posted October 16, 2020 Author Share #129 Posted October 16, 2020 The CL/Sigma 100-400 appears to have an AF memory. In the following shots it focused "through the gate" on the bushes in front of the car behind it despite putting the patch on the gate - normal AF behaviour. But: when I locked AF on the bottom of the gate, released the shutter and took a number of AF shots with approx the original framing, focus patch on the gate again, it focused consistently on the gate. The experiment was repeatable. Welcome, dear visitor!

Marac Posted October 16, 2020 Share #130 Posted October 16, 2020 It's a great lens really is. I used it with my CL (now owned by the Wife) and my S1R, to be fair, it is a lot better, for me, when used with the S1R, however, I gave my CL to my Wife & sold the 100-400, I prefer the Leica 80-200 f4.0 ROM version with the S1R as it becomes stabilised, I have yet to try it with an APO 2x converter but will one day. The Sigma L mount lenses that continue to impress me for FF option 14-24 f2.8 is incredible, there is no other word for it, and the tight little 45mm f2.8 is very very good indeed. The 3 APSC offerings 16mm 30mm and 56mm all at f1.4 are brilliant, that is the kit my Wife now uses and is delighted with the results. Sigma are aware of the issues with the 100-400 and are working towards an update (I have been informed). 3 Link to post Share on other sites More sharing options...

bags27 Posted October 16, 2020 Share #132 Posted October 16, 2020 And a shout out for the Sigma 70 macro. An odd duck, but fantastically sharp. So glad to hear about the 100-400 upgrade. From what I see on this board, it does perform well with a full sensor, but the results for me, at least, with the CL haven't been great. 1 Link to post Share on other sites More sharing options...
HeinzX Posted October 16, 2020 Share #133 Posted October 16, 2020 For me the results of the 100-400 with the SL2 are good, even with the ad. converter. Same valid for the CL, but max. with the 1,4 extender - not with the 2 ply one. If a max. focal length of 280 mm is sufficient the Leica 90/280 is the winner. But this one is a heavy giant. What I have to add is, that I used the Sigma at situations with much light. And I think, that the ISOs are of importance. The SLs can be used at higher ISOs than the CL to achieve good results. That might be the reason why under lower light circumstances the results are better with the SLs than with the CL. Link to post Share on other sites More sharing options...
jaapv Posted October 16, 2020 Author Share #134 Posted October 16, 2020 The CL will return excellent results up to ISO 1600, even more with Topaz DeNoise AI. That, together with OIS, will suffice for pretty grotty light. I suspect that the difference you note is due to handling the lighter body mass.

LeicaS2 Posted October 30, 2020 Share #135 Posted October 30, 2020 I had shot this a few months ago with the 100-400 at ISO 800 1/8 second.and recently printed it on a 40"x60" metal panel. I include the close up crop to show the detail of a very small section it would represent a 9" section of the 60" panel. I did not have a tripod collar which would have helped greatly. The grain visible in the crop section is only visible if you are standing close to the print, ie two feet away. So, yes the 100-400 works OK at night, and yes one can blow up a CL file to 40"x60" depending on the subject. BTW I had turned off the IS since I was on a tripod. Welcome, dear visitor!

wda Posted November 3, 2020 Share #136 Posted November 3, 2020 Is there a consensus view on the need for or usefulness of the optional accessory lens tripod collar? Link to post Share on other sites More sharing options...
jaapv Posted November 3, 2020 Author Share #137 Posted November 3, 2020 I would not be without it - permanently attached. It is very practical to stabilize the lens by holding the foot. It is also - obviously- needed to attach a shoulder pod. It provides a connection for a strap, to carry the lens combo without throwing strain on the camera bayonet. 1 Link to post Share on other sites More sharing options...

pocholin Posted March 10, 2021 Share #140 Posted March 10, 2021 At 299mm, had to manual focus...need more practice doing that, could've been sharper. Welcome, dear visitor!
