Keep them coming! Huge thanks to Peter Karbe that he is giving this great insights in Leicas camera and lens developments, wether it’s for the Leica Store Singapore like in July or here.
Great video and lot of interesting facts. Nick, thank you for sharing - I enjoy your videos very much. Cheers from Poland from a Leica enthusiast (M10, 50 APO, 50 summilux)
This was incredibly informative and helpful. Thank you! I wonder if you could set something up to do the same thing with the Leica R lenses. I would like to know the how the R compares to the M in terms of the grading system he used in this video.
Really interesting to hear about the design decisions behind the M system lenses, and the various technologies that allowed improvements over the years. The information about sensor package thickness also explains in detail why my M lenses perform better on my Leica M body than if I adapt them on my Fuji GFX (besides obvious image circle limitations). Horses for courses :-)
David, you can ask him yourself - there is another webinar tonight. It's about the SL lenses. leica-akademie.com.au/product/leica-akademie-webinar-m-system-lens-design-with-peter-karbe/ The recording will be online here in a couple of weeks.
Hi Stephen. I don't believe so but you can apply the same info to all the M lenses - the Summarit lenses are just a bit 'slower', but are of the same image quality even when used wide open.
I'm very impressed by Dr Karbe : a life dedicated to Leica lenses. I understand the challenge : size, performance, robustness, ease to use = not easy to build ! But why aren't M lenses weather sealed then ? Other question : constant aperture Zoom are not Leica's choice to preserve size and weight. However SL zooms are big and heavy. So I don't understand the point.
Have a listen to Dr Karbe's lecture on SL lenses and this will give you a perspective on the design criteria for all lenses. SL zoom are big because they are very high quality - size is directly related to optical quality, particularly for auto focus zooms with built in image stabilisers. I can't speak for the weather sealing but given that M lenses are mechanical, they are far more robust and less prone to water damage than electronic lens anyway.
Hard to say in general terms but some of them certainly are. It allows for more flexibility in terms of tolerances when dealing with larger lenses. Mind you the SLR lenses are humongous compared to Leica M glass - one of the main attraction of the M series lenses. 01:27:33
Comparing lenses is multidimensional, but I can tell you one way in which I prefer the Leica M. I have a few G master lenses but don't have a macro lens. Currently I digitally scan my film using an extension tube. The 35mm Summicron with 2 extension tubes *and* an M to E mount adapter clearly outperforms all of my other lenses, including G Masters with tubes for this task. The Leica Summicron 35 with tubes and a mount adapter is so damn good at scanning film that I'm not in any rush to buy a true macro.
Early on in the presentation some confusion over the term ‘depth of focus’ when really Peter K means ‘depth of field’. Depth of focus occurs inversely to depth of field, so in a large format camera where you have less depth of field in the subject field (due to a greater image magnification) you actually have more depth of focus at the film plane, whilst the inverse is true with the smaller Leica format, where you have naturally more depth of field in the image field (due to less image magnification) but less depth of focus at the film plane, which means, amongst other things, that the camera needs to be built to a higher standard of precision, a natural for Leitz since the beginning. On a different note, people talk about ‘Leica glass’, which usually is very good, but I also think that Leica have always generally produced 35mm-format lenses, especially for their RF cameras, which have had, and still have, the most attractive and stylish external physical forms, that is, the size and shape of the lens barrels, iris rings etc. Like their rangefinder cameras, Leica lenses look and feel good even before you shoot with them.
Brilliant presentation. Peter Karbe is an absolute master and I’m proud to own some lenses that he designed.
I never tire of Peter’s presentations. Thank you Nick.
Our pleasure!
Very impressive presentation. Liked the cut away & explanation about the Noct lens.
Glad you liked it!
Great presentation. I helps me to understand what is Leica Look, and why Leica lenses are so good and expensive.
Glad it was helpful!
Thanks for this video - Mr Peter Karbe is a great prof and gentleman
Thank you Roberto
Thank you for this incredible presentation.
Very informative talk. Now I know why images from my M are so amazing. Thanks
Keep them coming! Huge thanks to Peter Karbe that he is giving this great insights in Leicas camera and lens developments, wether it’s for the Leica Store Singapore like in July or here.
You are welcome.
Thank you for a most informative presentation. Particular;enjoyed the history of Leica and the 35mm format.
Glad you enjoyed it!
Hello from the UK! What an excellent presentation - I learnt so much watching the Maestro at work.
Glad you enjoyed it!
Great video and lot of interesting facts. Nick, thank you for sharing - I enjoy your videos very much. Cheers from Poland from a Leica enthusiast (M10, 50 APO, 50 summilux)
Many thanks!
Wonderful presentation by Peter “Shoot wide open!!!” Karbe. AKA: The lens god ❤️
A few hints in there about Leica's 'secret sauce'!
What a wonderful presentation
We all now have a far better understanding of what makes the Leica so different from all other camera systems
Hi Ronald. Glad you enjoyed it.

Hi Filibert. This mostly applies to the wides, the standards and telephotos can work quite well on other cameras.
Wonderful! Can you follow up with a question for Peter? Who does he trust to make the lenses in his eyeglasses?!! I want to go to that place!
David, you can ask him yourself - there is another webinar tonight. It's about the SL lenses.

Thank you
Very informative video. I would like to know specifically which 90 mm f/2 lens Peter was using for his macro photography.
Peter referred to the 50mm Noctilux when he was talking about his macro shots. Other than that I do not know, sorry.
@@LeicaCameraAustralia Thanks. Probably the APO.
Amazing Peter, great video both.
Glad you enjoyed it
Excellent session, I learned a lot
Glad you enjoyed it!
When is the CL webinar? can you send a link? Thanks
Hi Stephen
leica-akademie.com.au/product/leica-akademie-webinar-m-system-lens-design-with-peter-karbe/
It's tonight, 16 September, 7.00pm AEST.
When was the follow up session? Please post link
The session on SL lenses is also on the same UA-cam Channel.
ua-cam.com/video/_vyoAIOTIcs/v-deo.html
The link to the second seminar is broken. Was it cancelled?
I think you must have missed the start time - we took the registration offline once it had started. The recording will be here in a week or so.

Did he mentioned the Summarit lenses?
Hi Stephen. I don't believe so but you can apply the same info to all the M lenses - the Summarit lenses are just a bit 'slower', but are of the same image quality even when used wide open.
@@LeicaCameraAustralia got it thanks

Are Sony G Master lens better optical quality than Leica M glass?
Hard to say in general terms but some of them certainly are. It allows for more flexibility in terms of tolerances when dealing with larger lenses. Mind you the SLR lenses are humongous compared to Leica M glass - one of the main attraction of the M series lenses.

This is quite right - but just a slip of the tongue by Peter, speaking in English instead of German. Pretty sure he understands what he means!
