Can you ID the lens used for the image below? Top half is the full frame, bottom half is a crop.

 

Hint: Leica M camera

 

Answer must be as complete as possible, including brand, name, focal length, max. aperture (e.g. Leitz Noctilux 50mm f/1.2, Cosina-Voigtlander Heliar 75mm f/2.5, Canon Serenar 85 f/1.9, Leica Summicron-M-ASPH 75 f/2, etc.)

Leica Summilux-M 1:1.4/35 ASPH (maybe :-)

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

Andy,

 

I'm pretty sure it's been taken with a Canon Serenar 85 f/1.9

 

or maybe Canon Serenar 85 f/1.5

 

Anyway, that creamy bokeh looks like a Senenar wide opened.

Wow! What a fun game. My guess is the CV 35mm Nokton f1.2 (latest-asph). At least, that's the one in my collection that would produce something close to this.

Thanks Louis, Rich, and Art.

 

But only three connoisseurs in the whole Forum? I want at least 20 entries before revealing the truth.

 

What happened to all the folks who rabidly support a 28 'cron over a 28 Elmarit ASPH? Or a 75 'lux over a 75 'cron? Or won't use an M8 because a 75's drawing on 1.33 crop just can't be compared to a 90's drawing on 24x36. I would have thought eyes that sensitive would be able to nail this down to year of manufacture, let alone basic model.

I had a bowl of creamy bokeh with a little milk, blueberries, strawberries and half a sliced banana for breakfast this morning.

Andy,

 

If the point of focus was the tip of the nose (to bring the full face into focus) then the lens is front-focussing because the right eye is out of focus. Front focus suggests that the picture is shot on an M8 because the plane of focus on the sensor is so unforgiving, which means there's a 1.3 crop factor to consider.

 

The in focus area doesn't appear to have the razor sharpness of a modern aspherical lens but the shallowness of focus suggests a wide aperture. The bokeh is quiet harsh, which makes me suspect that the lens is wide open and I'm not convinced that we're close enough to the lady who is out of focus to allow the effective field of view of a 35 mm lens so I'm going to guess a Leica 50 mm f/1.5 Summarit lens.

 

Pete.

It is neither a 75 or 85, to wide a view from what I take as the shooting point and the DOF is to great for those longer lenses given what I think the shooting point is.

It is definitely a 50mm lens and I think the Lux Pre-ASPH shot at about f/between 1.4 and 2 (what is that f/stop anyway).

[JBA]

I agree with Shootist. It looks like a 50 'Lux pre-asph shot with an M8, which makes the focal length appear effectively longer.

Agreed. The OOF area indicates the shot was taken wide open or close to it, but the DOF does appear too great for the lens to be in that range of focal lengths.

I'd say Summilux 50/1.4 ASPH wide open

[jacobh]

I'll just throw in a guess: Cosina-Voigtlaender Nokton 1.1 / 50 mm at 1.1

[NZDavid]

I honestly have no idea. But I like it. Great bokeh really makes the difference with portraits.

 

My guess is it's at least a 50, wide open for sure. Maybe a 1.4 'Lux, but which model? ASPH or pre-ASPH? Hmm. I'll go for pre-ASPH. Not an oldie, I think. It's damned sharp.

 

I'd be pleased to have it in my camera bag, anyway.

50mm pre asph summilux

[wizard]

My first impulse was "Summilux 1.4/50 pre-asph", but on second thought it could be the Summilux 50 asph., too, as contrast seems to be higher than what I would expect from the pre-asph. at this aperture (1.4 or 2).

Hell! Even when I'm holding a rig I'm not sure what it is. It just does what I want....mostly.

 

My non-technical opinion is: M8 + 'Cron 75mm wide open.

 

Being wrong can be sooo much fun.

[andybarton]

Interesting that guesses so far have gone from 35 - 85mm...

[ArtZ]

I like this game! Thank you, Andy.

 

I'm probably wrong, but I believe this is not digital but film... . Some people suggested this is a modern lens. I don't think so. My first though was a Summilux 75 first generation at f/1.4 but the lux doesn't really draws like that, does it? This looks to me like old Canon lenses... so I still think this is a Canon Serenar 85 f/1.9 (or maybe a f/1.5).

[jacksparrow]

I'd say it's a 50

I don't think it's the summilux asph or pre (last gen).

I'd say it's a nocti, but not quite, so maybe the nokton?

I'd bet that, whatever it is it's 50 mm wide open

Hallo,

Look here: Interesting Leica gear

[erl]

Altering my position slightly, I reckon maybe a film cam with the 75mm crom wide open.

 

It's still fun being wrong!
