Four 50mm Leica Lenses 

Glad it was helpful!

The 50mm Summilux is Aspheric but does not have the APO designation. That’s what I am going by. And the 50mm f1.2 are hard to get so I could not include it, which is a pity from a completeness point of view!

@@LeicaCameraAustralia thank you overall for doing this as many maybe like the short form factor sometimes long ones are better specially from someone passionate about the topic 👍

@@LeicaCameraAustralia the lux has ridiculous CA and no abnormal lens elements. It’s not an APO lens

The 50mm Summilux has an aspherical lens element, as stated in the lens name. It's the fourth element from the front, just behind the aperture iris. It is an apochromatic design in that it fits the criteria of what qualifies a lens as apochromatic (as opposed to an achromat lens). The lens is not publicised as apochromatic, but our lens designer Peter Karbe is on the record as describing its apochromatic character.

Thanks, will do!

Sir, what you are discussing is Angle of View. Irrespective of Diagonal measurement, the accurate representation of distance between subject & background-object happens with a perfectly normal/natural focal length of 58mm ... not 35, 43, 50, or 85 ... and furthermore, whatever the sensor size or format (large, medium, fullframe, Apsc, M43) this rule doesn't change. I would prefer to use 58-65mm lenses on any camera system, & purposely keep all formats in my collection, if i can afford, thus achieving Wide-to-Tele Angle-of-View depending on the format. This is the correct method to be adapted.

@@chirag4 Do you have any recommendations for books/resources I could look into, to understand the physics behind such statements not in just a rule of thumb way, but from first principles. More the math, the merrier! TIA!

yes 58 mm is perfect , Middle ground

The foculpoint from the human eye is 66 mm and the F number is F 0.6

Agreed.

Got the brass summilux, thinking about a summicron, just for the size and weight

Thanks for sharing!

I also got serious about photography in the late 60’s. My first camera was a mamiya 35mm, with a 1.4, 50mm lens. I shot all my head shots at 1.4, and my work blew people away. Not because it was great, but no one ever seen blurred out backgrounds. Ya gotta love bokeh ! These days my tools are an m6, with a 2.0, 50mm Summicron. Rick….. 📷

Thanks so much!

75 noctilux is awesome .

Sell the 35 and get 28 instead. No entrapment anymore, you have 2 different tools for different use cases

Hi Peter. I agree and it’s a good idea, but IMO the nuances do not come over in a YT video. Maybe it would work in 4K. You have to look hard for the differences because they are all really good!

@@LeicaCameraAustralia I am so frustrated I'm trying to find people on RU-vid to show me why I would spend $5000 or $20,000 on the lens, I find really frustrating for me as a buyer to get really accurate information about why would spend the money on this gear and I don't understand if you can't show it on RU-vid why you would do a tutorial on RU-vid saying this is the lenses but you can't show us the difference between the lenses, please this is not attack on what you've done but I need someone to show me why I would spend $20,000 on the lens. You have to realise it's not easy for someone just to go out and get a $20,000 lens and Hire and have a play with it unless Leica or the shop know who you are it's not just gonna happen so we trust the people who do tutorials on the lenses to give us a visual and informative view the difference between each language lens. I'm just a frustrated photographer trying to find people who can inform me accurately to the difference between lenses and why I would buy them.

What part of the world are you in Peter?

Ok. Please email me. info@leica-akademie.com.au I have an idea for you.

I'd go for the Noctilux. I love its look, it's a very quirky look but at the same time, very distinctive.

No that's not normal. I have many R lenses, including that same lens, that work fine with adapters on my SL2 and the aperture will change as you'd expect.

The Noctilux. Easy choice!

Favourite - Noctilux. Most used - Summilux.

Sure thing. Got to start somewhere!

This is an extremely hard to get lens, and they are sold as fast as they come into stock so I have not had the opportunity to use it. Thus it could not be featured. Once I get my hands on one I can do an update.

I'd like to but R lenses are getting hard to find! I have one 50mm Summicron-R, but there are many different versions in this focal length. Check out Thorsten Overgaard for lots of R lens info.

This is true, it’s a subject distance thing. But then you change the framing if you change the lens. So if you keep the subject framed the same then you can change perspective by using using a different lens. All these factors are related.
