Any enthusiasm for the upcoming 1.25/75mm Noctilux?

exactly

How?

 

Edit - let me elaborate. Your Noctilux is a 50mm lens, whether mounted on your TL2, SL, S or your field camera. It’s always a 50mm lens. On your TL2 it gives the field of view of a 75 in 135mm terms because the sensor is smaller. It’s still a 50. Your 70 Summarit-S on your SL will give the field of view of a 70mm lens. On the S, the field of view is wider, because the sensor is bigger, but it’s still a 70mm lens.

 

The focal length is a factor of the lens, not the camera or the sensor size.

 

Similarly, the widest f-stop of your lens is a factor of the lens, not the sensor. The “f number” of the lens is the ratio of the focal length of the lens, divided by the diameter of the aperture. Neither changes with the sensor size.

 

So, the Noctilux wide open on the TL2 is still 50mm @ f/0.95, it’s just that the sensor only captures the central 2/3 of the image circle.

Perhaps you’re not acquainted with Neil’s supernatural auto-correct.

John thats exactly what I was trying to say .......so thanks for that.

I think you have to add that the depth of field is comparable to a 1.4etc. lens when cropped to a 2/3 sensor (but it absorbs as much light as a 0.95)

I am... Have seen it in action before...

Indeed...

A Summilux 35 would be so big it would block the rangefinder window.

 

I have grown used to the 50mm Nocti bumping into the window. Do you think it would be substantially worse? I also suppose that the EVF on the camera would mitigate the issue. I often use the EVF with my Noctilux because lower light difficulty focusing the RF and also because focus peaking helps me to better nail the thin focal plane of the Noctilux. Cheers--lt

I believe it would be bigger especially a hood for a 35.

I primarily use the rangefinder viewfinder. The reason I bought an M.

Sorry--I  just answered my own question The 1.2/35mm Nokton is nearly the exact diameter (62mm) of the Noctilux-50 and about 50mm shorter. So, I would have no issue with that size and RF window. LOL--of course this all just chatter as there is no indication a 35mm Moctilux is in the works.--lt

[lct]

No issue with that size and RF window perhaps but what about the blockage of 35mm framelines? Would be much worse than 50mm ones i suspect but i have no experience with big 35mm M lenses at all.

Paired with the fabulous MTLLRS (Magical thinking Leica Lens rendition System), otherwise known as the Leica Glow, which is not to be mistaken with mere lens aberrations.

Here is an image through a Leica optical viewfinder, showing how much the Zeiss ZM 35 f/1.4 blocks the 35mm frame: 18% ignoring the hood, almost 25% with the hood.

"35 mm Moctilux"?  That would be a HyperPrime copy would it?

 

Pete.

Funny, I have two of them, they both works perfectly fine.

Looking at the picture you just posted, it docent block anything. The only bit you need is the small patch in the middle of the RF and you picture clearly ilistrates it doesn't impede into the focusing patch

I meant Noctilux and you damn well know that.

hahahahahahah

But, having now seen the word 'Moctilux' I like it -- so will surely find a use for it.

 

Thanks, Linford!

[tobey bilek]

Not interested.   75 APO is great enough.

 

I tend to value small lenses and the only 1.4 I own is 50 Lux.  

[Trystero]

It's officially released today. No price tag yet, as far as I can see.
