Leica SL Lens System with Peter Karbe

[@astraeusone]

This presentation is a pure technical joy to listen. Thank you, Peter.

[@LeicaCameraAustralia]

You are welcome.

[@HatefYaminiOnline]

Always a pleasure listening to Peter Karbe discuss lens design.

[@LeicaCameraAustralia]

Totally agree!

[@thedisquisitivebarbarian4979]

This is such an amazing lecture, with just the right amount of technical detail. I’m especially grateful to understand the differences between the 50/1.4 and 50/2 SL lenses. Thanks, Peter!

[@LeicaCameraAustralia]

Glad it was helpful!

[@BackFocus11]

Peter is da man. Love his lenses! I just got my 35 APO SL and are amazed!

[@RenePfluger]

Peter Leave is head of a excellent Leica Team at Wetzlar. I am using M, CL and SL Lenses with enjoyment every day, meeting my highest expectations in photography. Thanks Peter for explaining his thinking around the world best lenses.

[@LeicaCameraAustralia]

An interesting insight for sure.

[@astraeusone]

Peter Leave?

[@stephenedmunds207]

well done to leica australia for getting mr karbe for this and the m lecture,fantastic.

[@LeicaCameraAustralia]

Hi Stephen. You are welcome.

[@tamilhoward9708]

I really enjoyed the video but really wish it was indexed so I could find the section easily where Mr Karbe talks about the 50 Summilux-SL. A great deal of his talk focuses on the Summicron-SL line.

[@LeicaCameraAustralia]

He is very proud (rightly so) of the Summicron line - and thus talks mostly about the newest developments.

[@tamilhoward9708]

@@LeicaCameraAustralia Understood. I am a Summilux girl so I was hoping for a little love for us too. Its all good though.

[@cmolina31]

Awesome deep dive into the SL lenses. Thank you,

[@LeicaCameraAustralia]

Glad it was helpful!

[@marc6652]

I'm very impressed by the quality of you videos. I wish Leica Camera France had the same ambition for their consumers. Congratulations to you both.

[@LeicaCameraAustralia]

Thank you very much!

[@sebastiang7183]

This is a great interview. Exceptional level of information that is well worth the time.

[@yungsoohong28]

So therefore with 1.5 crop factor in relative to contrast ratio in proportion we can get the same preception to FF with 1.5xfactor decrease in contrast ratio. ( I hope my question phase properly about the relativity to contrast level to crop factor of I focus in preception to the overall Capture imagery)

[@stevechang2135]

Fabulous presentation. Thanks for the presenter and the host.

[@LeicaCameraAustralia]

Our pleasure!

[@__-lt4hm]

Wow, thank you so much for this! As a current SL2 user with M and TL zoom lenses (for compactness) , it was interesting to hear Mr. Karbe's opinion about APSC, and cropping. Can't wait to get my first SL lens (especially the 21mm). I can confirm, the M and even the TL lens do not work as well on other L mount panasonic cameras (adapted S lens autofocus won't even work). Would love to hear about the TL lens as well as the S lens, especially adapted to the SL.

[@LeicaCameraAustralia]

Glad it was helpful!

[@yungsoohong28]

May I ask is that mean the ratio of contrast affecting what is perceiving in sharpest use. Meaning in translation in focus area ( DOF)

[@andreasehrenreich4497]

Great video! 👏🏻 I love my M240, the 35 Summicron and the 50 Summilux. These two lenses also work very well on my new SL2-S 😊 Greetings from Austria

[@LeicaCameraAustralia]

Thanks for sharing!

[@bobsykes]

This was fascinating. Really well done, thank you!

[@LeicaCameraAustralia]

Glad you enjoyed it!

[@delpierro0815]

Great information - I would love to see a similar discussion regarding the Leica Q lens design and the digital correction etc.

[@MattOsborne-MrLeicaCom]

Great video! Very informative and thanks Peter!

[@LeicaCameraAustralia]

Glad it was helpful!

[@MattOsborne-MrLeicaCom]

@@LeicaCameraAustralia it will probably cost me more money ha but very interesting. I review and use mostly M and LTM Leicas so SL glass is another can of worms (and R.. I found a few points at the end especially interesting). Thanks

[@carlosnunes5717]

Great video, thanks a lot. I would love to have similar information about the SL zooms and the TL lenses if it`s not expecting too much, or where can it be seen, best regards

[@qnetx]

Superb presentation. Thank you very much for sharing.

[@LeicaCameraAustralia]

Thanks a lot

[@fsi2210]

Thank you, this was also incredible.

[@Andy-qi3kd]

thank you for this very valuable insight into the manufacture of lenses. For leica ethusiasten these are the most valuable videos on the net, presented in an exceptionally personable way. Many Thanks !!

[@LeicaCameraAustralia]

Glad it was helpful!

[@miketan6050]

peter sure knows what is he talking about. very technical but informative.

[@wilfredshum3703]

Is there actually one on TL lenses with Peter?

[@sanfordlavine1760]

Thank you Nick and Peter for another great presentation from a master of lens design. Is it possible to obtain Peter's presentation slides on the M and SL lenses. I would find them helpful in expanding my knowledge.

[@LeicaCameraAustralia]

I'm sorry, that won't be possible. You can of course see all the slides in the video.

[@dfj555]

I have the Leica SL2-S, and I'm interested in purchasing the new Leica Summicron APO 35mm ASPH. I value smaller size, but will the M APO produce similar results as the SL 35mm?

[@LeicaCameraAustralia]

Yes. In a word. The 35mm APO-Summicron-M is most certainly up to the standard of the 35mm Summicron-SL. I have used both on the SL2 and I have no doubt at all.

[@tonn5673]

worth every seconds to listen from part 1 and need to learn more

[@markwalch702]

I enjoy the very detailed information about the SL lenses in video thank you very much even if it was 6 days later thanks

[@LeicaCameraAustralia]

Glad it was helpful!

[@philmtx3fr]

Gréât vidéo. I learnt a lot there . Thx for that.

[@RenePfluger]

I ask myself after going to the presentation, if 40 mp at the M10 R is too much for the M Lenses looking at the diagram comparison 35 SL and 35mm? Do I understand it wrong?

[@LeicaCameraAustralia]

Hi Rene. The M lenses are pushing at what is possible with the design constraints of such lenses - small lenses are challenging to make, as Peter explains. If you need to go to more megapixels then the SL lenses allow that, but they are of course bigger. I have been using a 180mm Elmarit-R on my SL2 and whilst a tad soft at f2.8, at f4 it's fully up to the 47MP sensor. Older M lenses might benefit for stoppoig down a bit, new ones not so much. The 75mm Noctilux-M is a good example, fully sharp at f1.25 on the M10R.

[@sanfordlavine1760]

@@LeicaCameraAustralia would this apply to the M10M sensor? I would like to use my 28mm 2.8 R PC lens on the SL2 and M10M

[@eis-bl4xw]

If the summicron 50 f2 is better than the summilux 50 f1.4 for the SL, why is the Lux more expensive? Seems like light flux is the only thing going, is that really that big of a deal considering that the cron is not far behind on that?

[@LeicaCameraAustralia]

f1.4 lenses will always be more expensive than f2 lenses for a variety of reasons, not least of which is the amount of glass required. Personally, I prefer the Summicron because the DoF fall off is very cleverly designed to appear more pronounced than f2 would normally indicate. It's also a much newer design and a lot lighter!

[@jukeboxjohnnie]

didnt know a 21mm was on the way..

[@LeicaCameraAustralia]

It's on the road map - 21mm and 24mm for the SL2 and SL2-S
